The Interrogator (2019–…): Season 1, Episode 2 - Overkill - full transcript

The scene is horrific
the minute you walk in the door.

...Behind me.

My first impression is this is
very, very personal.

Now it's getting
more interesting.

He's dug himself a hole,

And he's having
to look up to see bottom.

He's no longer
a possible suspect.

He is the right person
who did the wrong thing.

Houston, texas,
america's fourth largest city.

I served as a homicide detective

With houston's finest
for over 23 years.



I've investigated
over 400 murders

And solved 90%
with a confession.

Once I have a suspect
in the room,

I don't quit until I get
justice for the victims.

I am homicide detective
fil waters.

This was one of the most
rage filled, brutal killings

That I have been
a part of the investigation.

It's a case that
I'll never forget.

I lived with my mom
down the street from becky.

I felt like that little girl
that needed a grandmother,

And I felt like becky,

She was that grandma
that really needed a grandchild.

So we kind of filled the void
for each other.

She always to me to,
"come in,



And I'll fix you
somebody to eat."

I was there every day with her.

And I spent the most
amazing times with her.

That morning, I called her,
and I was like,

"well, she's not answering
because she's probably asleep."

But later, I called her again,
and I got no answer.

She always answer my calls,
so for me not to hear from her,

It put me into distress.

So I just ran over there.

It was unlocked.

I just pushed the door open,
and that's when I saw her body.

I knew she was dead from
the moment I opened the door.

I saw the blood.

On April 13, 2009,
my partner and I were assigned

To the capital murder that had
occurred on easter Sunday.

Our victim in this case had been
identified as rebecca claybrook,

55-year-old white female
living alone.

She is found, she's laying
on the floor of her kitchen

In a massive pool
of her own blood.

She is nude, and there is
blood spatter everywhere.

The first take that I have on it
is this is very, very personal.

This is somebody
that knows this victim,

And something occurred
that caused them to lash out

And act on her
in such a violent manner.

I just wanted to know
who did it and why.

She wouldn't hurt a fly.

It broke my heart because at 17,
I lost somebody

That I really started loving
at a young age.

Becky's mother had
recently died,

And there was an estrangement
between becky and her daughter.

I did not know becky
when her mom was around.

I met her afterwards,
and once her mom passed,

That's when her door was
an open door to everybody.

The fact that
she's found naked

And on her back,
legs slightly spread apart,

Certainly the first
indication there is

That she's gonna be not only
a victim of the murder,

But she's going to be
a victim of sexual assault.

Dna was in fact
recovered from the victim

And from that dna, the dna lab
was able to create a profile.

No forced entry
on the house.

Every homicide cop knows that if
you don't have forced entry,

It's likely that it's someone
that the victim knows.

Given the personal nature
of the murder itself,

It's pretty apparent to me that
she opened the door willingly

And let somebody in that house.

She just didn't know
she was introducing death

Into her house.

One thing that is of note

Is the number of bloody
footprints all over the place.

And they're good, good prints.

She was stomped to death.

To the degree that that same
imprint that we see in blood

On the floor is on becky's scalp
underneath her hairline.

Becky ends up dying as a result
of blunt force trauma

To her head, and the weapon
that is used is a tennis shoe

At the end
of the suspect's foot.

A tremendous amount of force.

And again, this is telling us
that whoever the suspect is

It's got to be personal
because this is overkill.

This is a rage fueled murder.

The crime scene unit
is able to take pictures,

And they're able
to send it off to

The texas department
of public service,

Who can compare the shoe prints
with a shoe catalog.

So the results of
the testing on the tennis shoes

Is if they're a cheap skateboard
type shoe

Nd it's a size 12,
which would indicate

That it's likely
going to be a man's shoe.

We speak to gina, and we're
asking her about these shoes.

Do we know anybody around here
that may wear this style of

A shoe, and she directs us
to a young man, teenager

There in the neighborhood.

He was this punk rock
hard core teenager.

And he would stand outside
and just gawk at becky.

It was really creepy.

When we talked
to his grandmother,

She explained to us
that she'd been raising them.

The grandmother also informed us
that the night of the murder

He had been asleep.

As the guardian,
we asked her if we might take

A buckle swab for a dna sample.

And the grandmother
very graciously gave us

Permission to do that.

The buckle swab is a long q-tip.

We hand it to the person that we
want to take that sample from.

They put it in their mouth,
and like they're brushing

Their teeth, they pull it out,
they pop it in a box.

We send it off the lab.

It's the best way to take
a dna sample for analysis.

When the results came back,
he was excluded from any kind

Of connection to the sample
that was found in becky.

And because
of that elimination,

Now we can move on to the next
step in the investigation.

Becky's cellphone had
been found at the scene,

And we find in becky's phone

A reference to
"a hunk of burning love."

Obviously we want to know
who is hunk of burning love.

So we speak to gina

Because becky had
a relationship with her,

Sharing a lot of personal things
with gina.

Gina was able to identify
hunk of burning love,

Roy olivarez,
as becky's duplex neighbor.

Roy had lived on the street
in a different house

When he was married.

According to gina,
the relationship between

Roy and becky had begun
before he moved

And broke up with his wife.

So one can presume that
that relationship with

Becky and roy may have been
a factor in the split up

Of the marriage.

From that point in time,

Becky would have
some sleep overs with roy.

His wife would
come visit him,

And that's when becky found out.

He wasn't fully separated.

That's what led to them
really breaking it off

And not speaking
and being on bad terms.

Love's a very intense emotion,
as is hate.

Those emotions can flip.
Is that what happened here?

On easter Sunday 2009,

55-year-old becky claybrook
was found stomped to death

In her own home.

We speak to gina.

Gina is the one
that finds becky.

She put us in the direction
of roy olivarez.

Lives directly next door.

You could knock out the wall
in becky's house

And step right into
roy's living room.

Roy was this handsome
50-something-year-old

That drove a harley that just
turned becky on.

I think it was
more of an obsession.

When she found out
he wasn't fully separated,

She couldn't take the fact
that there was another woman

There while she was with him.

We contact roy olivarez
to come down and talk to us.

We buckle swab roy.

Again, the dna analysis is going
to either make him

The prime suspect
at that point

Or it's going to eliminate
him from the investigation.

I'm trying to determine what
the extent of this relationship

Was between he and becky.

He does tell me they've had sex,
but he is not being terribly

Detailed about that
relationship,

And he is framing it in a way
that it is a sometime affair.

So was this a way that roy was
able to control

Phone calls from becky?

So if he's with another woman
with his cellphone,

He doesn't want becky calling
him while he's engaged in his

"hunk of burning love"
activities with somebody else.

He said he was not present
in the home.

He had spent Saturday and easter
Sunday at another location.

With roy having told us
that he spent that

Easter weekend with his wife,

That would have been something
that we were going

To pursue later
based on the results of the dna.

But the results of that testing
is an exclusion of

Hunk of burning love.

It is as important
to eliminate people

As it is to find
the right person.

Now we're back to looking
at cellphones.

We want to check and see
who's the last person

That talked to becky.

We find that the last
phone call that she makes

Is to a man named robert dray.

She told me multiple times
about the sex being too much.

We know that this looks
like a rage killing,

A personal killing.

And so bob dray, he's now primo
on our suspect list.

We found 55-year-old
becky claybrook sexually assault

And stomped to death
easter 2009.

From becky's phone,
we find that the last person to

Have spoken with her is
bob dray.

According to gina,
bob likes sex,

And becky didn't enjoy it.

The information we get
from gina

Is that becky has ended that
relationship around March 29th.

Now, this is important
because it's about two weeks

Before becky
is found stomped to death.

We know that this looks like
a rage killing,

A personal killing.

And so bob dray, at this point,

He's now primo
on our suspect list.

Bob dray is invited down,
and we have our discussion.

He tells me about
the relationship with becky,

And I asked bob
the $64,000 question

Which is, when was the last time
you had sex with becky?

Now it's getting
more interesting.

We have someone who has
admittedly told me

That he has had sex
with her two nights before.

When those words
come out in his mouth,

My thought was at that moment,

"we're in homicide,
and that's a clue."

And again, we're going to do
the buckle swab.

We send that to the lab.

Now there was no doubt
in anyone's mind

That the dna from examination
of becky was in fact bob dray.

Under normal
circumstances, semen can last

Inside the vaginal vault
up to two days.

We are in within the timeframe
of the possibility

That he had the sex
with her on Friday

And then further sexually
assaulted her on Sunday morning.

And it wouldn't have made
any difference

If the semen was deposited
on Friday or Sunday.

It would be him.

Question in my mind is,
did he find himself

At becky's house
on easter Sunday?

We do another canvas
of the neighborhood.

We're looking for anyone
that may have seen bob dray

On Sunday easter morning.

We find imelda del rio,
becky's neighbor.

Her house is facing
straight up the street.

Becky's house is on the left.

It's not a huge street,
so we can see activity,

We can see cars, we can see
things happening there

From imelda's front porch.

When we're talking about
bob dray, do we see any cars,

Do we see any activity
over there on Sunday.

Imelda says no.

But imelda shares with us
the one unusual activity

That did take place on that
street the night of the murder.

That night,
around 11:00, 11:30,

I got home with my husband,
and I got some tacos.

But we don't have nothing
to drink at home.

So I called my best friend.
She lived five houses away.

Imelda calls
a neighbor and says,

"have you got any drinks?"

Neighbor says, "sure I'll put
them out here in the carport.

You can come pick them up."

I go there,
and I pick up the drink.

When I come back,
I feel somebody is behind me.

And this guy,
he start chasing me.

Now she finds that
she's being pursued

In the middle of the street.

I was screaming for help.

But nobody's there for me.

I remember feeling his breath
behind me.

For one moment, you can feel
you're gonna die.

If the individual
that imelda del rio sees

Chasing her down the street
on the night that becky

Is murdered turns out
to be bob dray,

We're in the game now.

On the night that
55-year-old becky claybrook

Was sexually assaulted
and murdered,

We have an unknown male pursuing
becky's neighbor imelda del rio

Down the street.

I was screaming...

..."help, please,
somebody help me."

And then my husband, he saw me.

And then the guy saw my husband,
and he stopped.

The person that is
pursuing her doesn't

Come up to the door.

She's not sure where
he came from,

But she does know where he went,
and he turned around

And went the direction
of becky's house.

As a result of what imelda
tells us, we ask her

To come down and sit with
our sketch artist.

So now we have a sketch,
and we realize that the person

That we're looking at
is clearly not bob dray.

According to imelda,
the description we have now

Is an hispanic male in his 30s,
5'3", 160 pounds.

Imelda's sketch is really
a big, big step forward.

But more importantly,
the neighbor that she had gotten

The drinks from
has video cameras.

We get those videos,
and what we see is exactly

What imelda has described.

We see imelda come up.

She goes back toward her house,

And then it's seconds later,
we see this image

Running across the lens
of the camera toward imelda,

And you can see that
his actions are aggressive.

He's in pursuit.

And then we see him return,
moving toward becky's house.

And that's around midnight.

We got the video
out to the media.

We went to the neighborhood
showing that sketch.

The downside of it was
nothing came from it.

And at that point in time,
to our great disappointment,

The case went cold.

I feel like when I found her,
I kind of gave her

That piece of
"my death won't go unsolved."

I just want to know
who did it.

I made the promise to
her that I would make my best

Effort to bring that
person to justice and offer her

Some peace about what happened.

In January of 2010, my partner
at the time gets into the report

And finds one sentence in
a supplement written by

One of the original
scene detectives

Regarding a car that was found
a block and a half away

With a flat tire
parked against the curb.

I research the license plate.

We come to find out that
it is registered to a woman

Who lives in pasadena
named terrie espinosa.

Come to find out that she's got
a boyfriend, adam diaz.

And he bears a striking
resemblance to our sketch.

So we go to interview
terrie espinosa.

Every interview is planned.

What we went from terrie
is information that we can use,

And we don't want
to intimidate her.

So we want to take
the soft approach.

We want to walk in there and
talk about this benign topic of,

Why is your car parked
over here at this location?

We started talking
to her about the car,

And then she starts to tell us
about her boyfriend, adam diaz,

Starts to explain to us

That they had gone
to a party that night.

That it's up the street, around
the corner from becky's house.

So now we know adam is
in control of that car

On the night of becky's murder.

Terrie is starting
to fill in the gaps.

Now we know that adam had
become intoxicated.

They had an argument.

Adam's had anger,
alcohol fueled disturbances

With other women.

So there is a pattern here
of behavior

That would seem
to point to adam as our suspect.

We know that she's leaving
that party 9:30, 10:00-ish.

And adam is now
in control of the car.

And also on the man and from
the video looks like adam diaz

On the street chasing after
imelda at around

11:30 or midnight.

We know that the car
is discovered around the corner.

Adam diaz is nowhere
around the car.

And he returns to the residence
where he lives with terrie

At around 2:00 a.M.

When she drops this
about what looked like blood

On the cuffs of his pants,

The hair is starting to raise
on the back of my neck.

This is one of these moments
spider senses going off.

It was such
a large quantity of blood,

It seemed to be pouring
off of him,

Which was inconsistent with
his story that it was a fight.

She explained that that amount
of blood was not from a brawl.

We know what she doesn't know,

Is that becky
was stopped at death.

And the only reason there's
blood on the cuffs of his pants

Is because that is blood spatter
that is coming up to the cuffs

Every time he puts his foot.

On the back his head.

Now it's the proper time
to reveal our true purpose

For being there talking to her.

The look on her face
would have stopped a truck.

This is huge.

This is one of those moments
inside a homicide cop's heart

Where we know this is him.

This is our killer.

We are nine months out

From the capital murder
of becky claybrook.

And now in the investigation,

We are certain
we have our suspect.

His name is adam diaz.

Terrie and becky worked
together in a restaurant.

One day, becky invited
terrie to come over,

And terrie brought her
boyfriend, adam diaz,

To the house.

So that links adam diaz
to becky.

There's only one reason
why that car

Is left up there on that curb.

Adam is going
to becky's house.

Our theory now is he's drunk,
he's stupid,

He's wanting sex,
and he's heading to a location

Where he believes he's gonna be
able to get what he's after.

The next step for my partner
and I is to talk to adam.

In a non-custodial interview,
if adam starts to feel

Enough heat, he wants to leave,
he gets to leave.

I don't have, at this point,
enough probable cause

To seek a charge.

We already have adam
telling us that he knows becky.

So now we want to see
if there's a consistency between

What he's telling us and what
terrie has already told us.

He starts to talk about a party,

Talks about crashing the car
into the curb.

So these things now are
consistent with what terrie

Has told us, and they're putting
adam at becky's house.

Adam is clearly
being deceptive.

I'm looking at him, and I ask
him to explain something.

He's taking those moments
to think.

So he's trying to fashion
an answer, and those answers

That he's fashioning
are starting to get twisted.

So now we've got
a double deception.

He told terrie one thing.

Now he's telling us
something else.

He now knows that I'm doubting
virtually everything

That he is telling me to try to
explain the evidence

Of what he did to becky.

And he's dug himself a hole,
and he's having to look up

To see bottom, and he's starting
to realize that.

So I'm going to continue
to squeeze the vice.

The look on his face,
in texas we would say,

"he's like a calf
looking at a new gate."

And I know at that point now it
is coming to full realization

Of why he is there
and what we're talking about.

I don't have the ability
to keep him from leaving.

I don't have a warrant for him.

I have nothing other than I know
in my gut that he's our guy.

It's always a gamble.
You're rolling the dice.

But because he asks us
to come get him in the morning,

He wants to continue
the conversation.

That's an opportunity
I'm not going to pass up.

The next morning,
we go down pick him up

And take him immediately
to homicide division.

The fact that he has chosen

To come and speak to me
for the second

Non-custodial interview
tells me he is within

The circle of trust that we've
built and he trusts me enough

That he wants to come back
and talk to me.

Adam diaz admits to
being at becky's house

That night
and to assaulting her.

He then tells detective waters
that if he had flown into this

Rage that he described,
he wouldn't have been able

To stop himself, which is
consistent with the brutality

And the violence
we see at the scene.

When he gets to becky's,
he's intoxicated,

He is looking for sex,

And becky lets him in.
She puts up the fight.

The unfortunate result of that
is adam diaz throws her

On the floor of her own kitchen

And proceeds
to stomp her to death.

The confession
that detective waters

Was able to get from adam diaz
was crucial in this case.

Without the confession,
we couldn't have gotten justice

For becky claybrook.

He doesn't admit
to raping becky that night.

What we know is that
if a person wears a condom

Or if he doesn't ejaculate,

Then there is a potential
that a sexual assault happens

But that there's
no evidentiary dna.

I didn't want to
lay her to rest.

I wanted her
to stay with me forever.

This is the becky that I want
everybody to remember.

Her smile.

Here hair.

I want everybody
to remember this person

And know that because of her
trusting somebody

She got killed.

The dogged determination
by myself, my partner

To make sure that we could
bring this case to a close

And bring about
a sense of peace

For becky's friends
and family members,

We accomplished that,
and I feel good about that.
