It just sounds like something
bad is happening to her.
-I heard her scream, no, stop it.
-I heard some gun shots.
Drop it, whatever it is, drop it.
It is not true that I killed my wife.
We know what happened
because the video tells us.
The camera doesn't lie.
This time on
Killers Caught on Camera.
In the UK, a woman is picked up
by a stranger...
This person is the key to everything.
...who's obsessed
with horror memorabilia.
There was Chucky dolls.
There was a full size Freddy Krueger,
I just presumed they were
really, really into horror films.
It became clear that between them
there was a fascination
with true life crime,
serial killers, cannibalism.
And in Knoxville, Tennessee.
What is your emergency?
I just tried to wake up my daughter
for school and she has no pulse.
-How old is she?
-She's 16.
A secret spy camera is deployed
to catch a killer.
Audio is located up here.
Then we have the camera here.
-Everyday life, man.
-Let's go play some Modern Warfare.
These are young boys.
That's kind of dangerous.
Look at that fob,
is that light still on?
In the heart of the United Kingdom
in the West Midlands lies Tipton.
Home to carer Tracey Barrett.
I'm a friendly person. I'll talk
to anybody. That's my personality.
Tracey's home overlooks
the Birmingham canal.
A serene and tranquil space.
There's a lotta public coming here
a lot.
Got the canal boats
up and down all the while.
But what used to be a place of calm
for Tracey
is now tainted with bad memories.
In May 2019. Julia Rawson ran
a business selling pagan goods
with long-term partner,
Elaine Higginson.
She was a keen artist,
bubbly, outgoing
and well-known in the area.
On the 11th May, Julia spent the day
shopping with Elaine.
They parted ways
and Julia went towards the center
of Birmingham
to meet some friends.
But she got on the wrong bus and
ended up in the town of Dudley,
eight miles northwest
of Birmingham.
The next morning Elaine messaged
Julia but there was no reply.
Julia's friends also hadn't heard
from her.
Her silence was completely
out of character.
Elaine called the police.
Julia Rawson was reported missing
on the 14th of May 2019.
She was reported missing by a friend,
having last been seen on
the Saturday, late afternoon.
Police started to make enquiries.
The last sighting of Julia was in
a Dudley pub, the Bottle and Cork.
The pub was wired
with CCTV cameras.
Emi Polito is an expert
in forensic video analysis,
who has worked on hundreds
of cases in the U.K.
The daytime CCTV of Julia in Dudley
helps the police establish
what clothes she's wearing,
what footwear, you know,
what trousers, what jacket
and therefore really helps police
to build a picture.
Now have a look at this footage,
this is really interesting.
We see a person matching
the description of Julia
entering the pub.
And we can get a good view
of what she's wearing,
potentially some patterns
on her jumper.
This is really good detail that will
help with the police investigation
in terms of trawling
her whereabouts.
Julia was seen chatting
and drinking with a man.
At around 10:45pm
another man came in and sat down
at the far end of the bar.
The lamp is covering the person's
face completely.
It looks almost like he's done it
on purpose, doesn't it?
Julia approached him
and they started to chat.
This is really good because this puts
Julia in a specific location
at a specific time and she's
potentially talking to someone
that could be involved
in her disappearance.
The CCTV footage provided police
with vital clues.
This is potentially the last
person that Julia is seen with
before she disappears.
This person is the key to everything.
What was distinctive about him
is that in the evening in the pub
he'd rolled up his sleeves
and shown Julia
some quite distinctive tattoos
that he had on both arms.
Yes, the CCTV is not great.
We are not able to tell in detail
what these tattoos are,
but we know that this person
has got tattoos on both forearms
and this really helps the police
identifying the person, okay.
Luckily for us, not only do we get
a view of the tattoos,
but we also get a view
from different angles,
because as the person is showing
them, he is also rotating his arms,
and this allows us to see them
in even more detail.
There is a point in the CCTV
where the person leans over to Julia,
perhaps because he wants to talk
a little bit closer to her
and you can get a view of his face.
We perhaps can discern a long beard
on his face.
And again, this is now additional
information to the tattoos,
which can really help the police
identify the person
perhaps with the help of the public.
This imagery was shown by the
community support officer to people
who worked in Dudley town center.
We still had
a missing person enquiry,
and this person was going to be key
to that investigation.
The footage was circulated
on social media.
And a local security guard
recognized him.
Eleven days after Julia went missing
a man matching his description
was spotted in Dudley town center.
Who's been involved in a young
female that has gone missing.
We're looking for a female missing
person missing for about 11 days,
okay, we've got pictures on CCTV
with someone with your description
with her
so we just want details from you.
She's been missing for 11 days
so obviously we need to find her,
and because you look like
the person we've seen on CCTV
-we just need some details.
-Oh yeah, alright.
I'd probably chop all my hair off
though!
The men were identified as
30-year-old Nathan Maynard Ellis,
a former film and theater student
and his 25-year-old boyfriend,
David Leesley.
Professor Coral Dando is an expert
in forensic psychology
at the University of Westminster,
applying psychological research
to help criminal investigations.
We're looking for
a female missing person.
We've got some bodycam footage
of Nathan being stopped,
initially by one police officer
and he was then joined by at least
one other, maybe a third,
because he resembles the person
that was last seen with Julia.
With someone that matches
your description with her...
He reacts quite
sort of quite indifferently.
And because you look like the person
we've seen on CCTV
we just need to get some
details of you.
I'd probably chop all my hair off.
He tries to turn and do a bit
of reverse engineering we call it,
with the police officer,
and sort of say,
this is nonsensical,
doesn't make sense?
If I was involved, don't you think
I'd have changed my appearance?
Nathan was answering questions
and was being cooperative.
You'll notice from the body worn
camera footage
that the officer gives out
information and then says nothing.
And then Nathan fills it.
I'd probably chop all my hair off
though.
When people are being deceptive
that they don't like to be silent.
Silence is uncomfortable,
so they will always try and fill
a silence with something.
Conversely, David, his partner, seems
to react sort of very, very nervously
blowing his nose, coughing,
almost seems as if he is going
to be physically ill any point.
One thing we can notice
from the footage
is that the other male
is carrying quite a large bag,
which looks as if it's a pillow
or some sort of bedding.
And again, this could be interesting
piece of data for the investigation.
Police were confident he matched
the man seen in the bar.
We get a good idea from the images
of the size of the tattoos
and where they are located
in the arms.
Because they'd apparently
had gone under the sort of radar,
I suspect they'd let
their guard down.
So initially he may have
covered his tattoo,
but then he's become
more confident.
It's not unusual for people to think
that they're clever enough
to get away with this sort of thing.
As a result, he hasn't got to bother
to cover his tattoo
or change his appearance.
If he thought about it, that's
exactly what he should do,
it would have reduced the likelihood
that he'd get spotted.
When people do not have the chance
to develop a story or a lie script
or prepare for telling a lie,
it's a classic opportunity for
spotting when people are deceptive.
The fact that he changed nothing
about his appearance suggests to me
that probably, especially combined
with the response of,
"I would have changed something,"
he thought that'd make him
look more innocent.
He knew,
the police are going to ask me,
they'll pull up CCTV footage
or some picture and say,
hey, this looks like you.
And his response would be,
I would have changed my appearance
if I had been guilty.
Nathan was arrested on suspicion
of kidnapping
and taken into custody.
David provided a written statement
and claimed he and Nathan
were at home all night.
Police now had a suspect
in Julia's disappearance
but still no idea where she was.
They searched the canal
for evidence.
But it was the trawl of the CCTV
that revealed both men
made regular trips
along the canal path
with heavily laden carrier bags.
These houses here have got
CCTV footage
of Nathan and David walking up
and down the canal
with carrier bags in daytime
and night-time.
Police weren't sure
where the men were going
or what heavy items
were in the bags.
Julia was still missing.
CCTV footage also revealed Nathan
had celebrated his birthday
the day after Julia's disappearance.
The person could be trying
to look normal
and putting on a brave face.
They go out as normal
to have an alibi
so people don't point out
that they're acting weird.
Or it could be that they actually
don't have those feelings.
Tracey lived directly below them
and noticed something else odd.
There was light colored mud
going up the stairs.
I presumed it was my brother
and it wasn't on his feet.
See this is dark, isn't it? That's
dark, whereas if you go over there,
well you can see, look, it's lighter.
The soil going up my stairs,
not this color, this is dark.
The soil up my stairs
must be from the other side
cause it's paler,
lighter color, like clay over there.
That's coal dust and that definitely
wasn't up my stairs.
Next day, it had gone
and our cleaners don't come
till about Thursday, Fridays.
I just thought it was strange,
they must have come early.
Unusual night time cleaning
and Nathan and David remained
uncommunicative with neighbors.
If and when I did see them,
they were polite and well spoken.
That's the only thing I knew of them.
No conversation with them, as in
conversation, just the time of day.
And they had a unique taste
in home accessories.
There were Chucky dolls
on one of the walls.
There was full size Freddy Krueger,
I just presumed they were really,
really into horror films.
Nobody in their right mind
would have all that stuff.
It wouldn't be the whole flat full
because you could see as much
as you could from the canal
anyway without having to go inside,
you could see the horror stuff.
Police got a warrant
to search the flat
and confirmed what Tracey
had observed.
On top of the gory obsession,
a range of tools including a saw
and ornamental weapons.
It became really clear that between
them there was a real fascination
with true life crime,
serial killers, cannibalism.
Research has found that people
who like horror films
are more likely to be high
on what's called sensation seeking.
On top of that, horror films
often represent our greatest fears.
And so it gives you a safe way to
explore encountering those fears.
Psychologically, the reason
people like horror movies
is because they like the thrill,
being shocked.
Maybe even disgusted, but if you are
already predisposed to violence
and you've higher sensation seeking
and you're watching horror movies
you might take inspiration
from horror
to engage in your violent tendencies,
and then do terrible things
to people.
The shrine of horror memorabilia
was untouched,
but much of the flat
had been refurbished.
A van pulled up
and they was getting carpet,
light colored carpet out of the van.
Heard them banging around,
obviously them fitting carpet.
Then my brother said, there's rolled
up carpet in the bin. It stinks.
So I went down and smelt it,
oh God, yeah. That's... Meat.
You know when you've left meat
in a bin liner and that smell.
I presumed somebody had thrown,
threw a rotten chicken in the bin.
In most cases, but especially in
cases involving major crimes
such as murder or kidnapping or rape,
the police will gather evidence
from a small, confined area,
usually limited to the scene
of the crime.
Police pulled up the carpet
and found a stain.
It was blood and matched Julia's.
If and when the limited amount of
CCTV or video evidence
reveals enough information,
then the investigators can extend
their scope of search
for video evidence to larger areas,
and it becomes a little bit
like a tier level investigation.
CCTV footage revealed
Nathan getting rid of his couch.
And Tracey provided police
with more clues.
The front door wasn't working
for quite a while and I had a look
and there was a screw unscrewed,
so the door couldn't quite shut.
I put it right myself. I put the
screw back in so the door could shut.
They must've unscrewed it
so that in the night,
we wouldn't hear the door shutting or
opening because it makes a noise,
a buzzing noise for about two,
three, four seconds and shuts.
In retrospect, Tracey realized
something was going on.
I have always got my windows open,
whether it's winter, rain, snow.
I'd have heard that
all through the night.
Obviously getting rid of evidence.
Search teams abandoned the canal
and turned their attention
to the wasteland
on the other side of the water.
Sniffer dogs searched the area.
I received a call from the search
advisor that they'd made
what turned out to be a very grim
discovery.
They sent the dogs over that side
and that's when they found
body parts, which is just there.
Over the next few days, police found
the rest of Julia's body.
The body parts were very, very
well wrapped and preserved.
There was no scent given off for dogs
to pick up on.
There was no flies for us
to indicate on.
One of the body parts was exposed
slightly, but you couldn't see it.
A specialist search dog picked up
on the scent
from that first body part
that led us to that location,
which was not visible
to the naked eye, at all.
The first parts they found was
her head, torso and her thigh.
Twelve separate body parts
were found.
The search phase lasted a total
of 47 days. It sounds a long time.
However, the searches were split
over various areas,
canals, woodland, refuse tips,
search storage units,
premises, drains and other areas.
They were found scattered
in quite a large area.
But the drone footage really helps us
get an idea of the scale of the area
or where the body parts were found.
And this could indicate that
the suspect is forensically aware
and is trying to cover his tracks.
This took a considerable amount
of time and effort to be able to do.
Otherwise he would just dump
the body in one place.
The body parts were sent
to a specialist imaging unit.
Now, in this particular case,
the police had also employed
the services of Warwick University
to get a three-dimensional
reconstruction,
virtual footage of the actual
injuries on, on the body.
This is so the images aren't
too upsetting
or too graphic in the courtroom,
but also help establish
the extent of the injuries.
Analysis of the images showed
there were two types of incisions.
The first are were clean cuts,
the second more amateur.
We can see from the images
that there have been
some false starts
and failed attempts to dismember
or disfigure the body.
And the different styles of cuts
that we can see from the imagery
potentially suggests there was more
than one person in this operation.
The amateur cuts helped prove
a second person had helped Nathan
dismember Julia.
Nathan and David were charged
with murder.
Most of Julia's body was retrieved
but her kidney was missing.
People who murder, especially those
who spend time planning them,
sometimes take trophies
from the crime scene.
So they will keep things like photos
or they'll keep objects
or sometimes even things
like hair or body parts.
That is, however really rare.
So mostly if you take a trophy
or memento,
from the crime scene,
to remember your kill,
to remember what you did,
you'll take things
that are less obvious
and just belonged to the victim,
not actual organs.
It hit home the severity of what had
unfolded right under me.
Forensic pathology concluded
Julia had been bludgeoned to death
with a rolling pin
before being dismembered.
I realize that a lot of the detail
around what happened to Julia
in her final hours
and the terrible things
that took place within the flat
and the way in which
she was treated in death
and disposed of
in such horrific circumstances
will be absolutely terrible news
for the community
in which these discoveries
were made.
Nathan and David were tried
separately in December 2020.
During Nathan's trial,
a dark past came to light
when a character witness
took the stand.
She'd been in a relationship
with Nathan,
and he'd been sexually violent
towards her.
Having got a previous history
of sexual violence
and other types of violent behavior,
which may not be sexual in nature
but bring those two together
is a red flag
for future offending
in terms of murder.
So it's like a progressive type
behavior
and they get away with it once
or twice, maybe even get convicted,
serve a term imprisonment
for serious sexual violence
or other violent behavior.
So it could be GBH, ABH, affray,
that type of thing.
And then when they come out,
or if they haven't been convicted,
if they walk away, they will often,
men typically go on to murder.
For the murder of Julia Rawson,
Nathan claimed
diminished responsibility,
that it was a terrible accident.
And in a panic disposed of her body.
It seems as if Nathan
was the dominant one.
He certainly appeared to be
the person that was reaching out
to have psychologically damaging
relationships with women,
damaging to them physically
and psychologically,
but also damaging to himself
because he was trying to repress
the true him for the public,
for society at large.
That behavior fits within
what we would expect
and this acting out of fantasies,
obsessive thought behaviors,
psychologically damaging behaviors
is one of a long list of behaviors
that are exhibited by people
who try and repress their sexuality
and try and present a self to
the world, which is not true.
Nathan was sentenced to 30 years
for Julia's murder
and for four offenses
of historic rape.
At David's trial,
he was also found guilty of murder
and sentenced to a minimum
of 19 years.
This was a complex investigation
that involved an extensive search
of an area to locate Julia's body.
The sole aim of the investigation
to seek justice for Julia.
I hope that the result today provides
some solace for Julia's family.
I know that they are still grieving
for her loss,
but hopefully as a family unit
they can move forward.
So in this situation, we have two gay
men who are in a relationship
and they kill a woman.
And there has been some research
on what can feel incongruous.
So although many men who are gay
embrace aspects of femininity
that straight men often don't
embrace in the same way,
there still can be misogyny
within gay male communities.
So you're not outside of the norms,
not outside of culture entirely
just because you're a gay man.
And so you can still have that
hatred that can build up
and manifest in very violent ways.
CCTV is crucial
to a police investigation.
Certain circumstances might lead you
to slip up and to make mistakes.
Obviously, the more cameras and
more sources of video recordings are,
the more are the chances that you are
going to make that mistake.
After the images of Julia
and the person talking in the pub
circulated on social media,
police got a lucky break
and in investigations like this
you do need a lucky break.
I tried to put at the back of
my head, but no, it's shocking.
If only I could have heard something,
but I never heard anything unusual
to what I used to hear
from up there to be honest.
So I feel a bit guilty
that I couldn't help that woman.
And whatever she might have
gone through. I don't know.
All I hope,
is that she never felt it.
Cameras are an increasingly
common presence in our lives
capturing normal life.
A vital part of catching
Julia Rawson's killers
were the CCTV cameras in the bar
and along the canal.
But also, bodycam
on law enforcement officers.
We're looking for a female
missing person.
Less visible are the "hidden"
cameras on the high street.
This is a spy pen.
You have the camera here
and the audio is in the back
and it's a one button operation
and your SD card storage is here.
Spy cameras are now
so sophisticated
they can record good quality audio
and video, day or night.
The water bottle has a pin hole
built in the label.
The camera sits on the outside.
You can fill it up with water
making it a very good covert device.
And in our next case, essential
to capture a killer on camera.
It's definitely a game changer.
Now your everyday person
can come into a store
and then do their own investigation.
The US in the state of Tennessee,
Knoxville, it's historic capital
and home to almost a million people.
In 2016, 16-year-old Emma Walker
was a cheerleader
at Central High School.
She was dating star athlete
18-year-old, Riley Gaul.
Riley Gaul was a year or so older
than Emma.
He had just recently graduated.
They seemed like perfect
high school sweethearts.
But a few months
into their relationship
things started to change.
Riley began telling Emma
what to wear
and became possessive
and controlling.
Which played out through texts
and social media posts.
Her friends particularly
had been encouraging her
to part ways with Riley.
Her parents weren't happy either.
Especially when they saw
one particularly chilling text.
Her family did not approve
of this relationship.
The parents had, in fact,
at one-point grounded Emma
to try to keep her away from Riley.
They also banned Riley
from the house,
but he was always quick
to apologize.
As a teenager, your brain is still
physically growing
and until you're 25,
so into your early adulthood.
And so a 16 and an 18-year-old,
their brains aren't fully developed.
It means that you're less able
to make good long-term judgements
because one of the later parts
of your brain to develop
is your prefrontal cortex,
the front part of your brain,
and it's responsible
for you making good decisions.
After two years
of on and off dating,
Emma decided she'd had enough.
Emma finally was starting to realize
that it was time to move on.
The break-up affected Riley deeply.
He started texting her.
He was constantly
trying to get her to talk to him.
So there's usually an escalation
of stress before the breakup.
Then there's a peak after
because not only have you
had the stress
of the dissolution
of the relationship
and all that that entails,
but you also lose typically one
of your closest emotional supports.
So that person who you normally
would be turning to
in a high stress situation
is also gone.
Emma turned to her friends
for support.
Emma had gone to a party
after a football game,
talking to her friends about,
I'm done, I'm really done.
And while they're at this party
and it's kind of, it's dark
and he starts texting her claiming
that he's been kidnapped.
And then she gets some texts
that indicate
that perhaps he's been dumped
outside this party.
All the kids were scared.
And a couple of her friends
actually went outside first
and what they discover is Riley Gaul
kind of lying in a ditch,
face down, looks very disheveled
and as if he has been beaten.
Coercive tactics during a breakup
are quite common.
And coercive tactics can include
things like threatening to hurt
yourself or others potentially,
or to take other drastic steps
to force or you think force
that person to stay with you.
Now, the level of coercive tactics
we're seeing here,
staging a whole kidnaping
is absolutely wild.
That does not normally happen,
of course.
And so that level of coercion,
manipulation, lying is...
that's just the sign of something
much deeper
and much more obsessive
happening at this point.
Riley decided not to take
the kidnapping to the police,
but things turned even stranger.
The very next day a stalker emerged
in Emma's life.
Emma was home. Her mother
had gone, I guess, was at work.
Somebody knocks on the door,
it scares her,
a guy all dressed in black.
She was scared to death.
Her parents were so worried
they started walking her
to and from work
to make sure she was safe.
Police were keen to check
security cameras for clues.
As the police investigated the man
in black, they start pulling footage.
Nothing in the footage gave away
who the strange figure in black was.
Here we obviously see that there is
a dark character outside
who seems to be stalking her.
People who stalk
are usually obsessed
with the person they are stalking.
And usually they're a former
or current partner.
A huge piece of this feeling
like you are in love with somebody,
even if it's unrequited,
that you're following them around.
If someone's following you
or you think someone is,
that'll have profound psychological
implications for you.
Make you afraid to leave the house.
Or make you feel unsafe
within your house, even, right?
It can have really intimidating
consequences
for you and your loved ones.
On Monday morning
November 21st 2016,
just a couple of days after
the stalker incident at 6:00 am
Emma's mother, Jill, went into
her room to wake her up for school.
But she was unresponsive.
-She's dead.
-What is your emergency?
What's going on there?
I just tried to wake up my daughter
for school and she has no pulse.
-How old is she?
-She's 16.
-You said she's non-responsive?
-She's non-responsive, she's gone.
Emma was pronounced dead
from two gunshot wounds.
There was nothing
about Emma Walker
that would suggest that she had
caused her own death.
No apparent history of drug use
or reckless behavior.
Bodycams from officers
first on the scene,
picked up vital evidence.
There were at least two shell casings
there on the ground
that they were able to locate.
Every gun has a signature.
There's grooves and twist that occur
within the gun when you're firing it.
Emma was shot from outside
the house while she was asleep.
Once from above her head
and once from the side.
This bullet that entered Emma's
body had traveled through wood,
through the house there.
And so there was some damage
to that bullet.
Riley turned to social media,
an outpouring of grief.
Police started questioning
all of Emma's friends,
and the Sheriff's department
got a break.
One of his classmates said that Riley
had asked about fingerprints on guns
and whether those could be erased,
if they could be detected.
Sixteen hours after Emma
was declared dead,
Riley was questioned by detectives
at Knoxville police station.
Do you know why you're here?
What this is about?
They told me that y'all wanted to ask
me questions about my timeline.
-Where I'd been.
-Okay.
Riley was in shock.
He couldn't bring himself
to mention Emma by name.
The... The girl. She texted me.
-Which girl?
-The one who passed away.
Okay.
-What's her name?
-Emma.
Okay.
Referring to a victim
in a not quite dehumanizing
but certainly depersonalizing way
by calling her "the girl"
just feels like
a psychological tactic
to distance yourself
from the victim,
to not really see her
as a human being.
Don't name her because that evokes
who she really was as a human being.
And instead, to sort of go
"hmm", pushing it away,
because I think that makes it easier
to not feel maybe guilt,
not to feel the remorse you'd have
if you're constantly thinking about
the complexity of this victim
as a human being.
Police asked Riley
about his grandfather's gun.
Your grandfather has had a gun
stolen or missing.
Do you know what kind of gun it was?
I've only seen the gun one time
and didn't even see the whole thing.
They revealed his friends
Alex and Noah
said he asked about removing
fingerprints from a gun.
What if someone told us
that you showed them the handgun?
Do you ever remember
having a conversation with Noah
about getting fingerprints off a gun?
-How you get fingerprints off a gun?
-No.
Police released Riley,
he immediately texted his friends.
Police needed to eliminate Riley
or find some evidence.
The sheriff's department
was in a bit of a conundrum.
We've got lots of smoke.
We need some fire.
The police came up
with a radical plan.
If ever Riley is going to mess up
and say things to implicate himself,
it's not going to be to them.
It's going to be to his buddies.
So the sheriff's department talks
these boys into becoming spies.
Alex and Noah invited Riley over
to play video games.
Try to get him to talk about the gun.
Try to get him to talk
about the killing.
Go do your thing, guys.
His friends were wired for sound
and vision by the police.
-Hey, everyday life, man.
-Let's go play some Modern Warfare.
There you go!
These are young boys.
That's kind of dangerous.
-Look, the fob, the light still on?
-But they agreed to do it.
The secret camera was hidden
in a car key.
Audio is located up here
and then we have the camera here
and the different buttons
that would be on a car,
or different mode settings for audio
only, audio and video,
very covert, nobody would think
twice about a key fob.
This is insane.
This is the most ridiculous thing
that's ever happened.
The friends of a suspect
were undercover cops,
without guns, without badges,
and without protection.
And if... going wrong? Text us.
"Help!" or whatever.
-Yeah. Thanks, guys.
-No, thank you.
See you at the end!
When Riley arrived,
the secret camera was recording.
You only have one take at it.
There's only one time he's probably
going to be this open about it.
-What's going on, man?
-Nothing, just talked to Alex.
Right away, what you saw
was a bit of a psychopath.
I can't even be upset over her
as I'll probably get arrested
in the next couple of days.
But I understand
he told you about the gun.
It's pretty incriminating evidence
because of how relaxed he is.
I had that gun because I was scared
about what happened.
I know you don't believe me.
You probably don't either.
-We believe you.
-I'd never hurt her a day in my life.
He's talking as
if he doesn't even know her.
They said she shot herself
because of me. Or that I shot her.
Riley was worried the police
were closing in.
If I have to go to court
in front of a grand jury
and you have to testify or the cops
talk to you again
I'm trusting you guys with my life,
'cause I mean this is 70 years
in jail
if I get convicted of something
I didn't do.
He wanted his friends
to withdraw their statements
about his grandfather's gun.
If you tell them you were on LSD
drunk and high.
Your mind was altered.
Whatever statement you give them
wasn't a straightforward answer.
I don't know if it will be
on the phone or in person.
It's good audio quality,
good video.
He seems pretty relaxed. Definitely
doesn't know he's on camera.
Incredibly Riley then asked
his friends
to help him get rid of the gun.
It just needs to be gone.
Are you busy right now?
Like, are you about to do anything?
Ultimately, he tells these boys,
his friends,
that he's got to get rid of this gun.
-Well, can we go to the Bluffs?
-Yes, man.
'Cause I need to get rid of the
gun.
-At the Bluffs?
-I'll throw it into the water.
They will never find it.
The Bluffs are a remote area
of forests and deep lakes.
They didn't sign up to help him
dispose of a murder weapon.
I know it's terrifying. You don't
have to come if you don't want to.
That was part of the mission.
They had to carry it
all the way through.
Riley took them to
where he'd hidden the gun.
Noah and Alex waited in the car.
He got back in holding
a plastic bag.
-Success?
-It's a bag of trash.
I don't know what's in there.
-But it's in there?
-It's in there.
There's like some,
some black sweatpants.
His friends are basically like,
we got your back.
They're doing a pretty good job
of getting him to talk
and getting him to feel comfortable
and his friends could help him
get out of it.
So, yeah, that's,
that's pretty good evidence.
And Riley was unaware three police
cars were following close behind.
I'll carry... I'll carry it up.
Put gloves on. Get to the top.
Throw in the bullets individually.
Throw them down the cliff.
Throw the gun.
Yep.
Once his friends had eyes on the gun,
Alex texted the police
with the code word.
-What the... Oh, my God!
-Let me see your hands.
Let me see your hands!
Everybody put your hands
out of the vehicle now. Hands up.
Riley Gaul was arrested
and police recovered the bag
containing the evidence.
Right there. Right there.
-Move the bag back toward the seat.
-Yep, okay.
God... right, boys!
He has the gun and all this
black clothing and duct tape,
Basically a whole kit of evidence.
Not only did the bag contain the gun
used to kill Emma.
Also, inside were the clothes worn
by her "stalker",
solid evidence that the stalker
was in fact Riley.
-I need to get rid of the gun.
-At the Bluffs?
I'm going to throw it in the water.
They will never find it.
A camera doesn't lie and the audio
to back up who said it.
Having a covert device was definitely
a great way to get the evidence
that the friends were trying to get.
They obviously wanted closure
for the family
and today's technology makes it
easier for things like that.
Definitely the camera and audio
did the job it was supposed to do.
Riley Gaul was convicted
of first-degree murder.
Sentenced to 51 years in prison.
She was a young girl
and he really had been the only
boyfriend she had known.
So while it's a little sad that she
couldn't quite seem to break free,
it's not unusual
that she would have thought of Riley
in terms of her protector.
And that makes it all the more
upsetting,
I think, that Riley was playing
on those fears.
It's very apparent that what he was
trying to do was to win her back.

It just sounds like something
bad is happening to her.
-I heard her scream, no, stop it.
-I heard some gun shots.
Drop it, whatever it is, drop it.
It is not true that I killed my wife.
We know what happened
because the video tells us.
The camera doesn't lie.
This time on
Killers Caught on Camera.
In the UK, a woman is picked up
by a stranger...
This person is the key to everything.
...who's obsessed
with horror memorabilia.
There was Chucky dolls.
There was a full size Freddy Krueger,
I just presumed they were
really, really into horror films.
It became clear that between them
there was a fascination
with true life crime,
serial killers, cannibalism.
And in Knoxville, Tennessee.
What is your emergency?
I just tried to wake up my daughter
for school and she has no pulse.
-How old is she?
-She's 16.
A secret spy camera is deployed
to catch a killer.
Audio is located up here.
Then we have the camera here.
-Everyday life, man.
-Let's go play some Modern Warfare.
These are young boys.
That's kind of dangerous.
Look at that fob,
is that light still on?
In the heart of the United Kingdom
in the West Midlands lies Tipton.
Home to carer Tracey Barrett.
I'm a friendly person. I'll talk
to anybody. That's my personality.
Tracey's home overlooks
the Birmingham canal.
A serene and tranquil space.
There's a lotta public coming here
a lot.
Got the canal boats
up and down all the while.
But what used to be a place of calm
for Tracey
is now tainted with bad memories.
In May 2019. Julia Rawson ran
a business selling pagan goods
with long-term partner,
Elaine Higginson.
She was a keen artist,
bubbly, outgoing
and well-known in the area.
On the 11th May, Julia spent the day
shopping with Elaine.
They parted ways
and Julia went towards the center
of Birmingham
to meet some friends.
But she got on the wrong bus and
ended up in the town of Dudley,
eight miles northwest
of Birmingham.
The next morning Elaine messaged
Julia but there was no reply.
Julia's friends also hadn't heard
from her.
Her silence was completely
out of character.
Elaine called the police.
Julia Rawson was reported missing
on the 14th of May 2019.
She was reported missing by a friend,
having last been seen on
the Saturday, late afternoon.
Police started to make enquiries.
The last sighting of Julia was in
a Dudley pub, the Bottle and Cork.
The pub was wired
with CCTV cameras.
Emi Polito is an expert
in forensic video analysis,
who has worked on hundreds
of cases in the U.K.
The daytime CCTV of Julia in Dudley
helps the police establish
what clothes she's wearing,
what footwear, you know,
what trousers, what jacket
and therefore really helps police
to build a picture.
Now have a look at this footage,
this is really interesting.
We see a person matching
the description of Julia
entering the pub.
And we can get a good view
of what she's wearing,
potentially some patterns
on her jumper.
This is really good detail that will
help with the police investigation
in terms of trawling
her whereabouts.
Julia was seen chatting
and drinking with a man.
At around 10:45pm
another man came in and sat down
at the far end of the bar.
The lamp is covering the person's
face completely.
It looks almost like he's done it
on purpose, doesn't it?
Julia approached him
and they started to chat.
This is really good because this puts
Julia in a specific location
at a specific time and she's
potentially talking to someone
that could be involved
in her disappearance.
The CCTV footage provided police
with vital clues.
This is potentially the last
person that Julia is seen with
before she disappears.
This person is the key to everything.
What was distinctive about him
is that in the evening in the pub
he'd rolled up his sleeves
and shown Julia
some quite distinctive tattoos
that he had on both arms.
Yes, the CCTV is not great.
We are not able to tell in detail
what these tattoos are,
but we know that this person
has got tattoos on both forearms
and this really helps the police
identifying the person, okay.
Luckily for us, not only do we get
a view of the tattoos,
but we also get a view
from different angles,
because as the person is showing
them, he is also rotating his arms,
and this allows us to see them
in even more detail.
There is a point in the CCTV
where the person leans over to Julia,
perhaps because he wants to talk
a little bit closer to her
and you can get a view of his face.
We perhaps can discern a long beard
on his face.
And again, this is now additional
information to the tattoos,
which can really help the police
identify the person
perhaps with the help of the public.
This imagery was shown by the
community support officer to people
who worked in Dudley town center.
We still had
a missing person enquiry,
and this person was going to be key
to that investigation.
The footage was circulated
on social media.
And a local security guard
recognized him.
Eleven days after Julia went missing
a man matching his description
was spotted in Dudley town center.
Who's been involved in a young
female that has gone missing.
We're looking for a female missing
person missing for about 11 days,
okay, we've got pictures on CCTV
with someone with your description
with her
so we just want details from you.
She's been missing for 11 days
so obviously we need to find her,
and because you look like
the person we've seen on CCTV
-we just need some details.
-Oh yeah, alright.
I'd probably chop all my hair off
though!
The men were identified as
30-year-old Nathan Maynard Ellis,
a former film and theater student
and his 25-year-old boyfriend,
David Leesley.
Professor Coral Dando is an expert
in forensic psychology
at the University of Westminster,
applying psychological research
to help criminal investigations.
We're looking for
a female missing person.
We've got some bodycam footage
of Nathan being stopped,
initially by one police officer
and he was then joined by at least
one other, maybe a third,
because he resembles the person
that was last seen with Julia.
With someone that matches
your description with her...
He reacts quite
sort of quite indifferently.
And because you look like the person
we've seen on CCTV
we just need to get some
details of you.
I'd probably chop all my hair off.
He tries to turn and do a bit
of reverse engineering we call it,
with the police officer,
and sort of say,
this is nonsensical,
doesn't make sense?
If I was involved, don't you think
I'd have changed my appearance?
Nathan was answering questions
and was being cooperative.
You'll notice from the body worn
camera footage
that the officer gives out
information and then says nothing.
And then Nathan fills it.
I'd probably chop all my hair off
though.
When people are being deceptive
that they don't like to be silent.
Silence is uncomfortable,
so they will always try and fill
a silence with something.
Conversely, David, his partner, seems
to react sort of very, very nervously
blowing his nose, coughing,
almost seems as if he is going
to be physically ill any point.
One thing we can notice
from the footage
is that the other male
is carrying quite a large bag,
which looks as if it's a pillow
or some sort of bedding.
And again, this could be interesting
piece of data for the investigation.
Police were confident he matched
the man seen in the bar.
We get a good idea from the images
of the size of the tattoos
and where they are located
in the arms.
Because they'd apparently
had gone under the sort of radar,
I suspect they'd let
their guard down.
So initially he may have
covered his tattoo,
but then he's become
more confident.
It's not unusual for people to think
that they're clever enough
to get away with this sort of thing.
As a result, he hasn't got to bother
to cover his tattoo
or change his appearance.
If he thought about it, that's
exactly what he should do,
it would have reduced the likelihood
that he'd get spotted.
When people do not have the chance
to develop a story or a lie script
or prepare for telling a lie,
it's a classic opportunity for
spotting when people are deceptive.
The fact that he changed nothing
about his appearance suggests to me
that probably, especially combined
with the response of,
"I would have changed something,"
he thought that'd make him
look more innocent.
He knew,
the police are going to ask me,
they'll pull up CCTV footage
or some picture and say,
hey, this looks like you.
And his response would be,
I would have changed my appearance
if I had been guilty.
Nathan was arrested on suspicion
of kidnapping
and taken into custody.
David provided a written statement
and claimed he and Nathan
were at home all night.
Police now had a suspect
in Julia's disappearance
but still no idea where she was.
They searched the canal
for evidence.
But it was the trawl of the CCTV
that revealed both men
made regular trips
along the canal path
with heavily laden carrier bags.
These houses here have got
CCTV footage
of Nathan and David walking up
and down the canal
with carrier bags in daytime
and night-time.
Police weren't sure
where the men were going
or what heavy items
were in the bags.
Julia was still missing.
CCTV footage also revealed Nathan
had celebrated his birthday
the day after Julia's disappearance.
The person could be trying
to look normal
and putting on a brave face.
They go out as normal
to have an alibi
so people don't point out
that they're acting weird.
Or it could be that they actually
don't have those feelings.
Tracey lived directly below them
and noticed something else odd.
There was light colored mud
going up the stairs.
I presumed it was my brother
and it wasn't on his feet.
See this is dark, isn't it? That's
dark, whereas if you go over there,
well you can see, look, it's lighter.
The soil going up my stairs,
not this color, this is dark.
The soil up my stairs
must be from the other side
cause it's paler,
lighter color, like clay over there.
That's coal dust and that definitely
wasn't up my stairs.
Next day, it had gone
and our cleaners don't come
till about Thursday, Fridays.
I just thought it was strange,
they must have come early.
Unusual night time cleaning
and Nathan and David remained
uncommunicative with neighbors.
If and when I did see them,
they were polite and well spoken.
That's the only thing I knew of them.
No conversation with them, as in
conversation, just the time of day.
And they had a unique taste
in home accessories.
There were Chucky dolls
on one of the walls.
There was full size Freddy Krueger,
I just presumed they were really,
really into horror films.
Nobody in their right mind
would have all that stuff.
It wouldn't be the whole flat full
because you could see as much
as you could from the canal
anyway without having to go inside,
you could see the horror stuff.
Police got a warrant
to search the flat
and confirmed what Tracey
had observed.
On top of the gory obsession,
a range of tools including a saw
and ornamental weapons.
It became really clear that between
them there was a real fascination
with true life crime,
serial killers, cannibalism.
Research has found that people
who like horror films
are more likely to be high
on what's called sensation seeking.
On top of that, horror films
often represent our greatest fears.
And so it gives you a safe way to
explore encountering those fears.
Psychologically, the reason
people like horror movies
is because they like the thrill,
being shocked.
Maybe even disgusted, but if you are
already predisposed to violence
and you've higher sensation seeking
and you're watching horror movies
you might take inspiration
from horror
to engage in your violent tendencies,
and then do terrible things
to people.
The shrine of horror memorabilia
was untouched,
but much of the flat
had been refurbished.
A van pulled up
and they was getting carpet,
light colored carpet out of the van.
Heard them banging around,
obviously them fitting carpet.
Then my brother said, there's rolled
up carpet in the bin. It stinks.
So I went down and smelt it,
oh God, yeah. That's... Meat.
You know when you've left meat
in a bin liner and that smell.
I presumed somebody had thrown,
threw a rotten chicken in the bin.
In most cases, but especially in
cases involving major crimes
such as murder or kidnapping or rape,
the police will gather evidence
from a small, confined area,
usually limited to the scene
of the crime.
Police pulled up the carpet
and found a stain.
It was blood and matched Julia's.
If and when the limited amount of
CCTV or video evidence
reveals enough information,
then the investigators can extend
their scope of search
for video evidence to larger areas,
and it becomes a little bit
like a tier level investigation.
CCTV footage revealed
Nathan getting rid of his couch.
And Tracey provided police
with more clues.
The front door wasn't working
for quite a while and I had a look
and there was a screw unscrewed,
so the door couldn't quite shut.
I put it right myself. I put the
screw back in so the door could shut.
They must've unscrewed it
so that in the night,
we wouldn't hear the door shutting or
opening because it makes a noise,
a buzzing noise for about two,
three, four seconds and shuts.
In retrospect, Tracey realized
something was going on.
I have always got my windows open,
whether it's winter, rain, snow.
I'd have heard that
all through the night.
Obviously getting rid of evidence.
Search teams abandoned the canal
and turned their attention
to the wasteland
on the other side of the water.
Sniffer dogs searched the area.
I received a call from the search
advisor that they'd made
what turned out to be a very grim
discovery.
They sent the dogs over that side
and that's when they found
body parts, which is just there.
Over the next few days, police found
the rest of Julia's body.
The body parts were very, very
well wrapped and preserved.
There was no scent given off for dogs
to pick up on.
There was no flies for us
to indicate on.
One of the body parts was exposed
slightly, but you couldn't see it.
A specialist search dog picked up
on the scent
from that first body part
that led us to that location,
which was not visible
to the naked eye, at all.
The first parts they found was
her head, torso and her thigh.
Twelve separate body parts
were found.
The search phase lasted a total
of 47 days. It sounds a long time.
However, the searches were split
over various areas,
canals, woodland, refuse tips,
search storage units,
premises, drains and other areas.
They were found scattered
in quite a large area.
But the drone footage really helps us
get an idea of the scale of the area
or where the body parts were found.
And this could indicate that
the suspect is forensically aware
and is trying to cover his tracks.
This took a considerable amount
of time and effort to be able to do.
Otherwise he would just dump
the body in one place.
The body parts were sent
to a specialist imaging unit.
Now, in this particular case,
the police had also employed
the services of Warwick University
to get a three-dimensional
reconstruction,
virtual footage of the actual
injuries on, on the body.
This is so the images aren't
too upsetting
or too graphic in the courtroom,
but also help establish
the extent of the injuries.
Analysis of the images showed
there were two types of incisions.
The first are were clean cuts,
the second more amateur.
We can see from the images
that there have been
some false starts
and failed attempts to dismember
or disfigure the body.
And the different styles of cuts
that we can see from the imagery
potentially suggests there was more
than one person in this operation.
The amateur cuts helped prove
a second person had helped Nathan
dismember Julia.
Nathan and David were charged
with murder.
Most of Julia's body was retrieved
but her kidney was missing.
People who murder, especially those
who spend time planning them,
sometimes take trophies
from the crime scene.
So they will keep things like photos
or they'll keep objects
or sometimes even things
like hair or body parts.
That is, however really rare.
So mostly if you take a trophy
or memento,
from the crime scene,
to remember your kill,
to remember what you did,
you'll take things
that are less obvious
and just belonged to the victim,
not actual organs.
It hit home the severity of what had
unfolded right under me.
Forensic pathology concluded
Julia had been bludgeoned to death
with a rolling pin
before being dismembered.
I realize that a lot of the detail
around what happened to Julia
in her final hours
and the terrible things
that took place within the flat
and the way in which
she was treated in death
and disposed of
in such horrific circumstances
will be absolutely terrible news
for the community
in which these discoveries
were made.
Nathan and David were tried
separately in December 2020.
During Nathan's trial,
a dark past came to light
when a character witness
took the stand.
She'd been in a relationship
with Nathan,
and he'd been sexually violent
towards her.
Having got a previous history
of sexual violence
and other types of violent behavior,
which may not be sexual in nature
but bring those two together
is a red flag
for future offending
in terms of murder.
So it's like a progressive type
behavior
and they get away with it once
or twice, maybe even get convicted,
serve a term imprisonment
for serious sexual violence
or other violent behavior.
So it could be GBH, ABH, affray,
that type of thing.
And then when they come out,
or if they haven't been convicted,
if they walk away, they will often,
men typically go on to murder.
For the murder of Julia Rawson,
Nathan claimed
diminished responsibility,
that it was a terrible accident.
And in a panic disposed of her body.
It seems as if Nathan
was the dominant one.
He certainly appeared to be
the person that was reaching out
to have psychologically damaging
relationships with women,
damaging to them physically
and psychologically,
but also damaging to himself
because he was trying to repress
the true him for the public,
for society at large.
That behavior fits within
what we would expect
and this acting out of fantasies,
obsessive thought behaviors,
psychologically damaging behaviors
is one of a long list of behaviors
that are exhibited by people
who try and repress their sexuality
and try and present a self to
the world, which is not true.
Nathan was sentenced to 30 years
for Julia's murder
and for four offenses
of historic rape.
At David's trial,
he was also found guilty of murder
and sentenced to a minimum
of 19 years.
This was a complex investigation
that involved an extensive search
of an area to locate Julia's body.
The sole aim of the investigation
to seek justice for Julia.
I hope that the result today provides
some solace for Julia's family.
I know that they are still grieving
for her loss,
but hopefully as a family unit
they can move forward.
So in this situation, we have two gay
men who are in a relationship
and they kill a woman.
And there has been some research
on what can feel incongruous.
So although many men who are gay
embrace aspects of femininity
that straight men often don't
embrace in the same way,
there still can be misogyny
within gay male communities.
So you're not outside of the norms,
not outside of culture entirely
just because you're a gay man.
And so you can still have that
hatred that can build up
and manifest in very violent ways.
CCTV is crucial
to a police investigation.
Certain circumstances might lead you
to slip up and to make mistakes.
Obviously, the more cameras and
more sources of video recordings are,
the more are the chances that you are
going to make that mistake.
After the images of Julia
and the person talking in the pub
circulated on social media,
police got a lucky break
and in investigations like this
you do need a lucky break.
I tried to put at the back of
my head, but no, it's shocking.
If only I could have heard something,
but I never heard anything unusual
to what I used to hear
from up there to be honest.
So I feel a bit guilty
that I couldn't help that woman.
And whatever she might have
gone through. I don't know.
All I hope,
is that she never felt it.
Cameras are an increasingly
common presence in our lives
capturing normal life.
A vital part of catching
Julia Rawson's killers
were the CCTV cameras in the bar
and along the canal.
But also, bodycam
on law enforcement officers.
We're looking for a female
missing person.
Less visible are the "hidden"
cameras on the high street.
This is a spy pen.
You have the camera here
and the audio is in the back
and it's a one button operation
and your SD card storage is here.
Spy cameras are now
so sophisticated
they can record good quality audio
and video, day or night.
The water bottle has a pin hole
built in the label.
The camera sits on the outside.
You can fill it up with water
making it a very good covert device.
And in our next case, essential
to capture a killer on camera.
It's definitely a game changer.
Now your everyday person
can come into a store
and then do their own investigation.
The US in the state of Tennessee,
Knoxville, it's historic capital
and home to almost a million people.
In 2016, 16-year-old Emma Walker
was a cheerleader
at Central High School.
She was dating star athlete
18-year-old, Riley Gaul.
Riley Gaul was a year or so older
than Emma.
He had just recently graduated.
They seemed like perfect
high school sweethearts.
But a few months
into their relationship
things started to change.
Riley began telling Emma
what to wear
and became possessive
and controlling.
Which played out through texts
and social media posts.
Her friends particularly
had been encouraging her
to part ways with Riley.
Her parents weren't happy either.
Especially when they saw
one particularly chilling text.
Her family did not approve
of this relationship.
The parents had, in fact,
at one-point grounded Emma
to try to keep her away from Riley.
They also banned Riley
from the house,
but he was always quick
to apologize.
As a teenager, your brain is still
physically growing
and until you're 25,
so into your early adulthood.
And so a 16 and an 18-year-old,
their brains aren't fully developed.
It means that you're less able
to make good long-term judgements
because one of the later parts
of your brain to develop
is your prefrontal cortex,
the front part of your brain,
and it's responsible
for you making good decisions.
After two years
of on and off dating,
Emma decided she'd had enough.
Emma finally was starting to realize
that it was time to move on.
The break-up affected Riley deeply.
He started texting her.
He was constantly
trying to get her to talk to him.
So there's usually an escalation
of stress before the breakup.
Then there's a peak after
because not only have you
had the stress
of the dissolution
of the relationship
and all that that entails,
but you also lose typically one
of your closest emotional supports.
So that person who you normally
would be turning to
in a high stress situation
is also gone.
Emma turned to her friends
for support.
Emma had gone to a party
after a football game,
talking to her friends about,
I'm done, I'm really done.
And while they're at this party
and it's kind of, it's dark
and he starts texting her claiming
that he's been kidnapped.
And then she gets some texts
that indicate
that perhaps he's been dumped
outside this party.
All the kids were scared.
And a couple of her friends
actually went outside first
and what they discover is Riley Gaul
kind of lying in a ditch,
face down, looks very disheveled
and as if he has been beaten.
Coercive tactics during a breakup
are quite common.
And coercive tactics can include
things like threatening to hurt
yourself or others potentially,
or to take other drastic steps
to force or you think force
that person to stay with you.
Now, the level of coercive tactics
we're seeing here,
staging a whole kidnaping
is absolutely wild.
That does not normally happen,
of course.
And so that level of coercion,
manipulation, lying is...
that's just the sign of something
much deeper
and much more obsessive
happening at this point.
Riley decided not to take
the kidnapping to the police,
but things turned even stranger.
The very next day a stalker emerged
in Emma's life.
Emma was home. Her mother
had gone, I guess, was at work.
Somebody knocks on the door,
it scares her,
a guy all dressed in black.
She was scared to death.
Her parents were so worried
they started walking her
to and from work
to make sure she was safe.
Police were keen to check
security cameras for clues.
As the police investigated the man
in black, they start pulling footage.
Nothing in the footage gave away
who the strange figure in black was.
Here we obviously see that there is
a dark character outside
who seems to be stalking her.
People who stalk
are usually obsessed
with the person they are stalking.
And usually they're a former
or current partner.
A huge piece of this feeling
like you are in love with somebody,
even if it's unrequited,
that you're following them around.
If someone's following you
or you think someone is,
that'll have profound psychological
implications for you.
Make you afraid to leave the house.
Or make you feel unsafe
within your house, even, right?
It can have really intimidating
consequences
for you and your loved ones.
On Monday morning
November 21st 2016,
just a couple of days after
the stalker incident at 6:00 am
Emma's mother, Jill, went into
her room to wake her up for school.
But she was unresponsive.
-She's dead.
-What is your emergency?
What's going on there?
I just tried to wake up my daughter
for school and she has no pulse.
-How old is she?
-She's 16.
-You said she's non-responsive?
-She's non-responsive, she's gone.
Emma was pronounced dead
from two gunshot wounds.
There was nothing
about Emma Walker
that would suggest that she had
caused her own death.
No apparent history of drug use
or reckless behavior.
Bodycams from officers
first on the scene,
picked up vital evidence.
There were at least two shell casings
there on the ground
that they were able to locate.
Every gun has a signature.
There's grooves and twist that occur
within the gun when you're firing it.
Emma was shot from outside
the house while she was asleep.
Once from above her head
and once from the side.
This bullet that entered Emma's
body had traveled through wood,
through the house there.
And so there was some damage
to that bullet.
Riley turned to social media,
an outpouring of grief.
Police started questioning
all of Emma's friends,
and the Sheriff's department
got a break.
One of his classmates said that Riley
had asked about fingerprints on guns
and whether those could be erased,
if they could be detected.
Sixteen hours after Emma
was declared dead,
Riley was questioned by detectives
at Knoxville police station.
Do you know why you're here?
What this is about?
They told me that y'all wanted to ask
me questions about my timeline.
-Where I'd been.
-Okay.
Riley was in shock.
He couldn't bring himself
to mention Emma by name.
The... The girl. She texted me.
-Which girl?
-The one who passed away.
Okay.
-What's her name?
-Emma.
Okay.
Referring to a victim
in a not quite dehumanizing
but certainly depersonalizing way
by calling her "the girl"
just feels like
a psychological tactic
to distance yourself
from the victim,
to not really see her
as a human being.
Don't name her because that evokes
who she really was as a human being.
And instead, to sort of go
"hmm", pushing it away,
because I think that makes it easier
to not feel maybe guilt,
not to feel the remorse you'd have
if you're constantly thinking about
the complexity of this victim
as a human being.
Police asked Riley
about his grandfather's gun.
Your grandfather has had a gun
stolen or missing.
Do you know what kind of gun it was?
I've only seen the gun one time
and didn't even see the whole thing.
They revealed his friends
Alex and Noah
said he asked about removing
fingerprints from a gun.
What if someone told us
that you showed them the handgun?
Do you ever remember
having a conversation with Noah
about getting fingerprints off a gun?
-How you get fingerprints off a gun?
-No.
Police released Riley,
he immediately texted his friends.
Police needed to eliminate Riley
or find some evidence.
The sheriff's department
was in a bit of a conundrum.
We've got lots of smoke.
We need some fire.
The police came up
with a radical plan.
If ever Riley is going to mess up
and say things to implicate himself,
it's not going to be to them.
It's going to be to his buddies.
So the sheriff's department talks
these boys into becoming spies.
Alex and Noah invited Riley over
to play video games.
Try to get him to talk about the gun.
Try to get him to talk
about the killing.
Go do your thing, guys.
His friends were wired for sound
and vision by the police.
-Hey, everyday life, man.
-Let's go play some Modern Warfare.
There you go!
These are young boys.
That's kind of dangerous.
-Look, the fob, the light still on?
-But they agreed to do it.
The secret camera was hidden
in a car key.
Audio is located up here
and then we have the camera here
and the different buttons
that would be on a car,
or different mode settings for audio
only, audio and video,
very covert, nobody would think
twice about a key fob.
This is insane.
This is the most ridiculous thing
that's ever happened.
The friends of a suspect
were undercover cops,
without guns, without badges,
and without protection.
And if... going wrong? Text us.
"Help!" or whatever.
-Yeah. Thanks, guys.
-No, thank you.
See you at the end!
When Riley arrived,
the secret camera was recording.
You only have one take at it.
There's only one time he's probably
going to be this open about it.
-What's going on, man?
-Nothing, just talked to Alex.
Right away, what you saw
was a bit of a psychopath.
I can't even be upset over her
as I'll probably get arrested
in the next couple of days.
But I understand
he told you about the gun.
It's pretty incriminating evidence
because of how relaxed he is.
I had that gun because I was scared
about what happened.
I know you don't believe me.
You probably don't either.
-We believe you.
-I'd never hurt her a day in my life.
He's talking as
if he doesn't even know her.
They said she shot herself
because of me. Or that I shot her.
Riley was worried the police
were closing in.
If I have to go to court
in front of a grand jury
and you have to testify or the cops
talk to you again
I'm trusting you guys with my life,
'cause I mean this is 70 years
in jail
if I get convicted of something
I didn't do.
He wanted his friends
to withdraw their statements
about his grandfather's gun.
If you tell them you were on LSD
drunk and high.
Your mind was altered.
Whatever statement you give them
wasn't a straightforward answer.
I don't know if it will be
on the phone or in person.
It's good audio quality,
good video.
He seems pretty relaxed. Definitely
doesn't know he's on camera.
Incredibly Riley then asked
his friends
to help him get rid of the gun.
It just needs to be gone.
Are you busy right now?
Like, are you about to do anything?
Ultimately, he tells these boys,
his friends,
that he's got to get rid of this gun.
-Well, can we go to the Bluffs?
-Yes, man.
'Cause I need to get rid of the
gun.
-At the Bluffs?
-I'll throw it into the water.
They will never find it.
The Bluffs are a remote area
of forests and deep lakes.
They didn't sign up to help him
dispose of a murder weapon.
I know it's terrifying. You don't
have to come if you don't want to.
That was part of the mission.
They had to carry it
all the way through.
Riley took them to
where he'd hidden the gun.
Noah and Alex waited in the car.
He got back in holding
a plastic bag.
-Success?
-It's a bag of trash.
I don't know what's in there.
-But it's in there?
-It's in there.
There's like some,
some black sweatpants.
His friends are basically like,
we got your back.
They're doing a pretty good job
of getting him to talk
and getting him to feel comfortable
and his friends could help him
get out of it.
So, yeah, that's,
that's pretty good evidence.
And Riley was unaware three police
cars were following close behind.
I'll carry... I'll carry it up.
Put gloves on. Get to the top.
Throw in the bullets individually.
Throw them down the cliff.
Throw the gun.
Yep.
Once his friends had eyes on the gun,
Alex texted the police
with the code word.
-What the... Oh, my God!
-Let me see your hands.
Let me see your hands!
Everybody put your hands
out of the vehicle now. Hands up.
Riley Gaul was arrested
and police recovered the bag
containing the evidence.
Right there. Right there.
-Move the bag back toward the seat.
-Yep, okay.
God... right, boys!
He has the gun and all this
black clothing and duct tape,
Basically a whole kit of evidence.
Not only did the bag contain the gun
used to kill Emma.
Also, inside were the clothes worn
by her "stalker",
solid evidence that the stalker
was in fact Riley.
-I need to get rid of the gun.
-At the Bluffs?
I'm going to throw it in the water.
They will never find it.
A camera doesn't lie and the audio
to back up who said it.
Having a covert device was definitely
a great way to get the evidence
that the friends were trying to get.
They obviously wanted closure
for the family
and today's technology makes it
easier for things like that.
Definitely the camera and audio
did the job it was supposed to do.
Riley Gaul was convicted
of first-degree murder.
Sentenced to 51 years in prison.
She was a young girl
and he really had been the only
boyfriend she had known.
So while it's a little sad that she
couldn't quite seem to break free,
it's not unusual
that she would have thought of Riley
in terms of her protector.
And that makes it all the more
upsetting,
I think, that Riley was playing
on those fears.
It's very apparent that what he was
trying to do was to win her back.
