01x02 - Episode 2

[bunniefuu]

Paul. The Llandarcy
job is yours.

Hang on! Stop there,
please, sir! No, no, no...

No, no. That's my daughter!
That's my daughter! No!

Thank you. And thank
you for trusting me.

Stepdad. Dai Williams.

Alibi -

out driving his taxi that night.

Comparative mitochondrial testing
has shown a compelling link

between Sandra Newton and
Geraldine and Pauline.

You're dealing with a serial k*ller
and all that comes with that.

I thought this day
would never come.
He might still tell
us to bugger off.

Well, he might.

What's the plan then?

Turn the other cheek.

Tea and sympathy
till we get his DNA.

DI Paul Bethell.

I remember you
perfectly, thank you.

May we come in, Dai?

Hello, Pat.

Christmas came early.

To be opened later.

How the hell did you get this?

Can't tell you, mate.

Chris Wynne? I said
I can't tell you!

Gentlemen.

Right. Listen up.

I urge you to remember this.

The parents of both girls are
adamant, absolutely adamant,

they were sensible lasses

who wouldn't have got
in a stranger's car.

So, anyone with
links to the girls,

even just a casual acquaintance,

goes to the top of the list.

Yes, Bethell?

Sir, I really think
we should be looking

at Sandra Newton
alongside these girls.

Her stepfather, Dai Williams,
is worth another look.

Did you not hear
me the first time?

Was I, uh, unclear?

Did I mumble?

No, sir.

Did I not say we stay focused
on Geraldine and Pauline,

come hell or high water?

Good.

You and Philip are on tapings.

Tapings?

Detective Sergeant Jenkins
will show you the ropes.

Here we go, boys.

We're reopening the investigation
into Sandra's m*rder,

and we thought you
should hear it first.

Why?

There's some new
DNA evidence, Pat.

Tells us certain things,
important things.

Sandra was k*lled by
the same man that k*lled

Geraldine Hughes
and Pauline Floyd.

No.

It's the DNA, confirms it.

It's John Dilwyn Morgan,
isn't it? Got to be.

I always said he was soft
in the head, didn't I?

Bothering Sandra when
he had a wife at home.

Have you checked his DNA yet?

No, not yet, Dai. Well,
what are you waiting for?

We haven't checked anyone's
DNA yet, but we will.

We'll be mounting a
targeted swabbing operation.

When the police told me about
Sandra and John Morgan...

..I think they expected
me to be shocked...

..and think less of her...

..grieve less for her.

Was I thrilled about her
seeing a married man? No.

Did it mean anything in
the face of losing her?

What's a targeted
swabbing operation?

Basically taking DNA
from lots of men...

..to find a match
for our k*ller.

I'm afraid that'll
include you, Dai.

It's just for purposes
of elimination.

As Sandra's stepdad, we have
to clear you, that's all.

Oh, you do, do you?

"Purposes of elimination."

I like that. Nice.

Is it his blood?

You say the DNA tells
you the same man

k*lled Sandra and
the Llandarcy girls.

Is it his blood?

Erm, no.

No, the DNA profile was
taken from his semen.

There you go.

Morgan was seeing
Sandra, we know that.

It's got to be him, right?

There is something else
we need to share with you.

The DNA tells us
that there was semen

from two different men
on Sandra's clothes.

Now, if one was a result of Sandra
and Morgan being intimate...

..that suggests the other No.

No. We were told over and
over she wasn't r*ped.

Over and over.

We were.

Categorically.

See? She wasn't r*ped.

She wasn't.

She and Morgan had a row,

and he lost his head.

And it was all over quick.

Very quick.

I'm so sorry, Pat.

DNA, it's like, um,

a very powerful torch.

It lets you see in the corners
that you couldn't see into before.

Well, that's a
good thing, is it?

That's a fair question, Dai.

"That's a fair question, Dai."

Don't insult my
intelligence, OK?

Just don't.

I was on CID's sh*t
list from day one.

And I have it on
very good authority

that you were the
one who put me there.

If you were a gambling man...

Yeah, which I'm not.

That's why I said "if", Phil.

He looked like a worried man.

"Might do a runner" worried?

Who might do a runner?

Oh sorry, Geraint.
Erm, Dai Williams.

Sandra's stepfather.

Taxi driver, perfect cover, didn't
have an alibi for the three murders.

Did he own an 1100?

No, but, er...

The drivers shared cars back then,
so could've got hold of one easy.

We've had a new e-fit from
one of the r*pe victims.

Oh, and that's a '73-era
photo of Dai Williams.

We won't be taking
his DNA, then?

Thank you, sir.

Not so fast, lads.

We have another proud
owner round the corner.

Mr Joseph Kappen.

Right, rinse and repeat.

I'll get his statement,
you do the car.

Catch.

If this lands on my
foot, I'm blaming you.

How's that?

"I really think we should be
looking at Sandra Newton, boss."

We should!

Not even trusted to
take a statement!

One more f*cking
word, all right?!

Thank you.

Right, we're off. Give
her back the keys.

Thank you, Mrs Kappen.

Well?

The car's been on
bricks all summer.

What else? What was Kappen like?

Bit of an oddball.

Think it's worth speaking
to the neighbours?

Check the bricks story?

I'll put it in my report.

Uniform to follow up.

And I'll make
another suggestion.

Smarten yourself up, Bethell.

We're the public face
of the constabulary.

Remember that.

Right. Who's next?

Press conference?

I'm not gonna lie to you,
I'm bloody bricking it.

Say the wrong thing,
the wrong body language,

the press jump on you.

Becomes the whole bloody story.

Oh, that's not the spirit.

I know, I know.

Just be yourself.

When you talk about the case,
the girls, the families...

..you're impressive.

People listen.

Listen, OK?

OK.

Ugh.

OK. What is this?

An empty milk bottle?

Ha-ha.

Come on. Fess up.

Why does she always
think it's us?

It's like living with
a bunch of students.

I'm off.

Oh, I can run you
in if you want.

Yeah.

Love you.

Ta-ra.

Love you. Love you!

Bus is good for her, socially.

I think on some
level, she knows that.

You're the expert.

I am. Love you.

I know.

Yeah.

It's just, erm, once
bitten, you know?

We had a right shitshow
with the press back in '73.

Still bear the scars.

Well, don't worry. I wasn't
expecting you to say anything.

No.

It's important you're here,
but I'll be doing the talking.

Right you are, ma'am.

Thank you for coming, everyone.

South Wales Police are today
commencing the reinvestigation

of the unsolved murders

of Geraldine Hughes and
Pauline Floyd in 1973.

A breakthrough in DNA forensics

has now formally linked the
murders of Geraldine and Pauline

to the m*rder of Sandra
Newton in July 1973.

In other words, we are now
actively trying to find

and apprehend a serial k*ller.

The k*ller is still out
there enjoying their freedom,

enjoying their life,

but we are committed to
bringing them to justice.

Operation Magnum will
involve an intelligence-led

DNA swabbing campaign,

and we are asking the public
to cooperate, come forward

and assist the investigation with
any information they may have.

Someone out there knows, or
suspects who this man is.

We only need a name.

Why are you wasting
time on old cases

when the crime rate's
through the roof?

Sadly, the passage of
time takes nothing away

from the horror and pain

the families of these
girls have endured.

Therefore we will
do everything we can

to bring this man to justice

so they can experience
something resembling closure.

Hey, he smashed it, Jackie
couldn't get a word in.

Freezer's arrived, boss.

So I see.

All right, we're
in business, boys.

So, we store the DNA swabs here

and then we submit them to
Colin Dark at the laboratory.

Daily? Weekly?

The first of every month.

Before that, we need a
prioritisation matrix

to determine the first batch
of 500 men for swabbing.

What's that when it's at home?

A way to triage
our top suspects.

See, now I understand.

I did a course on
prioritisation matrices once.

A man of hidden talents.
Just a two-day thing.

It was that or
health and safety.

Oh, speaking of which,
it's incumbent on me

to warn you that most of
the case papers in there

are plus 25 years old,

so there's a danger of paper
mites and associated allergies.

Good to know.

The matrix, what
parameters are you scoring?

Well, were they suspects
back in the day and/or

resemble physical descriptions
provided by key witnesses

and/or own a white
Austin or Morris 1100?

Then your usual markers.

We need to go back
through the files

and get our list of
possible contenders.

That'll give us a lot
more than 500 suspects.

Yes, it will.

We'd better get cracking, then.

Three teenage girls were
m*rder*d in West Glamorgan.

The bodies of Pauline
Floyd and Geraldine Hughes

were found in woods
near Llandarcy.

Three months earlier, teenager
Sandra Newton had been m*rder*d

15 miles away. This year, DNA
tests confirmed that the girls

were k*lled by the same person,

but they say recent
forensic intelligence

has given them cause
to investigate further.

A breakthrough in DNA forensics
has now formally linked

the murders of Geraldine and Pauline
to the m*rder of Sandra Newton

in July 1973.

In other words, we are now
actively trying to find

and apprehend a serial k*ller.

The k*ller is still out
there enjoying their freedom,

enjoying their life...

These were the girls
you knew, weren't they?

Geraldine and Pauline, yeah.

How?

Er, I was at school
with them for a bit,

and then I worked at the factory
with Geraldine and her mum.

You worked in a factory?

Yeah. I did!

What about the other one?

Er, no, I didn't
know the Neath girl.

Erm, I didn't know Sandra.

When we moved from
Coventry, it was tough.

It was like landing on the moon.

Mum just couldn't handle it,

and Dad said we had to
keep smiling at all times,

be "good immigrants", you know?

Geraldine and Pauline were the first
people I met in the playground.

It was Geraldine's birthday,
and she'd smuggled a cake in.

She offered me a
slice, and, uh...

..that meant everything.

Well, if they're
looking at it again,

it's got to be a
good thing, right?

Yeah.

Are you sure?

At his house?

Then what happened?

Oh, my God. No way!

Really?

No!

With these 500 men, what
will you do if they refuse?

What do you mean?

Well, if they won't
give their DNA?

Well, we can't force them.

Not legally.

Won't be an easy ride, mind.

I've got history with more
than a few of them on the list.

Let Phil and Geraint do
those house calls, please.

Paul...

..you have to go into this knowing
that you might not find him...

..and having some inkling as
to how you will deal with that.

Well, sometimes it's
the things you don't do

that come back to haunt you.

Like I knew John Dilwyn
Morgan was innocent.

But after Ray Allen tore a strip
off me, I did f*ck all to help him.

Nothing. Just kept my head down.

Yeah, well, sometimes
that's the smartest move.

That's what I told myself

at the time.

Hello, Mrs Morgan.

DI Paul Bethell. Is John in?

You're joking.

I chucked him out years ago.

You'll probably find him
down the Labour Club.

You want my DNA?

That's right, John.

What's to stop you
putting it on a dead body?

Screwed then, aren't I?

I told everyone
and their mother...

..you didn't k*ll Sandra.

I didn't believe it then,
I don't believe it now.

I'm gonna f*cking
burst into tears.

Look, John...

..you give us your DNA now...

..and we can clear
you Clear me?

I was tried in the
court of public opinion.

And found guilty. I'm
well aware of that, John.

Yeah, well, you'll
know I lost everything.

How will a DNA test
change that, eh?

It's too late.

Oi!

Where do I spit?

So if you'll just let
us have a DNA sample,

we can eliminate you
from our enquiries.

I'll tell you what,

I'll give you a DNA sample when you
give me my f*cking clothes back.

Sorry?

October '73, you took my
denim jacket for testing.

Hawkwind and Sabbath
patches on the back.

Never bloody saw it again!

I don't see how it took DNA
for them to link those murders.

It was obviously the same bloke.

Yeah, what're the chances of two
K*llers living five miles apart?

Maria.

My schedule is creaking, might
need to off-load some classes.

Yeah, OK.

Can we go over everything
later? I can do five.

Thanks.

Here we are.

15 down, 485 to go.

Where's the boss?

Oh, there's one test he
wanted to do himself.

Can you open your
mouth, please, Dai?

Dai?

Open your mouth, please, Dai.

Thank you.

Oi!

What do you want?!

What do you want?!

This is bloody harassment!

We're taping half the cars in
South Wales. Why not one more?

Cos Dai Williams
is not on our list.

The end.

You need to start
packaging your samples.

You're behind.

Yes, sir.

Let me tell you
something, Bethell.

Every station I've
ever set foot in,

there's a bloke in the corner on his
own, long face, in-tray up to here.

A bloke no-one wants
anything to do with

unless they dump
their sh*t on him.

You know why?

Cos once upon a time, he
thought he was different.

Golden.

Too clever not to follow orders,
too good not to be in a team,

too sharp not to chase
down his own leads.

He thought he was f*cking special,
and the rules didn't apply.

But guess what?

He wasn't and they did?

Ah, sh*t.

You all right?

Fancy a pint?

f*ck, aye.

Give me a solid on this, Colin?

And rush it through.

We have a system in place, Paul.

I know, I helped to design it.

We're still not prepped
for the first 500.

Call it a sneak preview.

The exception that
proves the rule.

Dai Williams.

Oh, I'll be in touch,
Paul, fear not.

Where the f*ck have you been?
You said you'd be home at seven!

It's gone ten! I cooked.

I didn't ask you to.
You did, actually.

I said, "What do you fancy to
eat?" You said, "Lamb chops."

Well, I'm not hungry.

Listen to me, I sound
like my bloody mother!

I'd k*ll for a beer,
though. I'm 23 years old.

I don't want to play the part
of the bloody nagging wife!

Then, do us both
a f*cking favour.

I don't deserve this.

You and me, we're a
team or we're nothing.

Where've you been?

Sandra Newton's stepdad.

I've been keeping an
eye on him when I can.

Like, off your own bat?

Is that a good idea?

Probably not.

But it's keeping me sane.

I suppose.

Every job has their bad days.

I'm not doing my job, Karina,
that's the f*cking point!

We're still on the tapings.

They're not inclined to
come and speak to us.

I would ask them...

come to this.

Watching the bloody news to
find out what's going on.

I would be, or my colleagues
would be the only person

to know who they are.

So at the end of that round,

the scores are like the
legs on a GM turkey.

Your promise.

I'm here.

I don't know what I'll
do if Dai isn't a match.

Always had such a strong
feeling about him.

Yeah, well, DNA trumps
strong feelings.

Apparently.

There's no doubts on that score.

Phil has.

Always asking if DNA's
everything it's cracked up to be.

Did I tell you he came
forward as a witness?

Dai, not Phil?

You never told me
anything back then.

Just walked straight into the
station saying he wanted to help.

Is that so weird?

I mean, he had lost his
daughter. Stepdaughter.

That's not an
indicator of guilt.

I'm just saying.

When you have a feeling about
someone, there's a reason.

You all right there, sir?

Er, yeah, I just want
to talk to somebody.

OK.

Is that our man,
according to you? Yeah.

Yeah.

Leave him to me.

When I came back, he
was still in the lay-by.

And, like, hunkered
down behind the wheel.

Like he didn't want
you to see him?

Exactly.

Navy.

Maybe purple.

Oh, I see.

All the colours of
the f*cking rainbow.

What? No. I'm telling
you the truth.

Three weeks, Dai. Three weeks
it's taken you to come in

and tell us about Lay-by
Man. You know why.

I'm Sandra Newton's stepdad.

You've got a bloke parked
outside my house every night.

We certainly do not.

That's most likely
gentlemen of the press.

Do you know what my old dad
used to say, God rest his soul?

Any time anyone does you
a turn, always ask why -

Hang on, hang on, I came
in here in good faith.

Don't interrupt me, Dai.

I've got some
questions about Sandra,

and it's very important
you answer them truthfully.

Do you understand me?

Did Sandra look upon
you as a father?

I certainly like to think so.

So you got along?
The two of you?

We had our ups and downs.

Oh, well, let's focus
on the downs, if we may.

What?

No!

I bet she drove you up the wall,
though, pretty girl like that,

under your roof, in your bathroom,
passing you on the stairs...

That's disgusting!
I get it. I get it.

You raise her, you clothe her,
sweets, pocket money, all that.

But you expect
something back, right?

You want a return
on your investment.

I don't know what you're
on about. You lose it.

You lose it, and then
two things happen.

You get away with it, and
then you get a taste for it.

Before you know it, you've got
two live birds in the back of your

taxi with only
one thing Stop it!

No, YOU stop it, Dai. Right now!

And tell me what happened,
save us all a lot of grief.

I'll write it down, all
you got to do is sign it.

Make it easy for yourself,
Dai, make it easy for Pat.

Pat doesn't know I'm here.

You see?

Yeah.

I think I do see, Dai. Yes.

There was no man in
that lay-by, was there?

Guv.

Mr Allen wants to
know what's going on.

He says, and I quote, "If this
has got anything to do with

"the bloody Neath girl,
there'll be hell to pay."

Right.

To be continued, Mr Williams.

Chris, take his clothes for
full forensic examination.

Hi, Sita Anwar.

Thank you.

OK.

Could you take a seat
in there Thank you.

We've got a visitor.

Sita Anwar.

Says she was a friend of
Geraldine and Pauline's.

Says she was with them on
the night they were taken.

I thought it was worthy Yeah.

sh*t, I'm, erm, supposed
to update Jackie.

Geraint?

Sita Anwar. See what she wants?

Best china, please. All right?

Right, can we get on top of
the next batch of samples?

I don't want Colin sitting
there twiddling his thumbs,

and Jackie's going to ask
for an update, so, uh...

Sure.

Right.

See you later.

I thought I'd give
you my contacts

in case I can be helpful
in any shape or form.

OK. Well, that's appreciated.

Do you want a tea
or a coffee, Sita?

Er, no, thank you, I've got
to get back to work. Busy day.

And what do you do for work,
if you don't mind me asking?

I work at Oakcross school.

Right.

Wow.

You must be busy.

Do you want to tell
me something, Sita?

Such as?

I don't know.

About that night, maybe?

Erm, I was supposed to go
to the Top Rank with them.

But my dad put a stop to it.

I think it's great
you're doing this.

Fresh eyes is what it needs.

What makes you say
that? About fresh eyes?

Oh, nothing. Just, er...

No disrespect to you,
but some of the '73 lot

were a winning mix of
useless, arrogant and drunk.

Right.

No surprise they
never solved it.

Tell me what you really think.

Oh, you weren't, erm...

No, too young to have
worked on it, right?

Yeah.

Is there anything
else I can do for you?

No, no, thank you.

Nice to meet you, Sita.

Yeah, nice to meet you.

Is it him?

If you mean, "Is
it Dai Williams?"

I'm afraid to tell you, no.

His DNA doesn't match the
control profile of our k*ller.

No.

Colin, are you sure?

Have you checked...? Dai
Williams is not our man, Paul.

sh*t.

It's not just Dai Williams -

the first batch of 50 swabs
have all come back negative.

Yeah.

A fair few healthy
candidates in there.

ALL our candidates
were in there.

All our favourites anyway.

I suppose we have to manage
our expectations and our hopes.

What do you mean?

I mean, we're in this for
the long haul, aren't we?

Yeah, we are.

Can you get me in front of
the Chief Officer Group?

Yeah, course.

Getting the begging bowl
out already, are we?

Just on testing alone,
we're gonna blow our budget

in four months, three maybe.

We need to buy some time
to get through that list.

I'll call them first thing.

As per your request, we've
expedited your application.

But I have to inform you, we see
no grounds to increase your budget

or extend the lifespan
of Operation Magnum.

With respect,

I think the grounds
are self-evident.

We haven't caught this man yet
because we haven't matched his DNA.

But the swabbing
programme is in full swing

so now's the time
to hold our nerve.

I'm sorry, Jackie.

We'd like to help,
but we're stretched,

and, frankly, this was
always a bit of a punt.

Sorry, but Jackie's right.

This is the time
to hold our nerve.

He's out there. And we're
close, and I've got a feeling,

but if an old copper talking
about his gut doesn't cut it...

..let's not forget
why we've reopened

this case in the first place.

Sir, we owe it to these
girls to find him.

In, you know, Mr Willoughby.

How'd you guess?

Jan Stiles.

Number seven.

What makes you think he's in, Jan?
Never answers the door, does he?

Postman, Jehovah's,
Cancer Research...

He rarely comes out in the day.

And you won't see
a light on, ever.

Not from January to December.

Does he live alone?

Got a wife and two
sons, would you believe?

Home-schooled his kids.

Doesn't trust the state.

Doesn't trust anyone.

Do you know, I've lived four
doors down from him for 25 years

and never had a conversation.

He's missing out.

You know I'm famous for
my heavy knock, right?

Not THAT famous.

Took the door off
a Securicor once.

Let's hear it, then.

Mr Willoughby?

South Wales CID.

f*ck off!

So much for your heavy knock,
we got our first refusal.

That's about the size of it.

Anything in the file
about him in '73?

Not a lot, but what we got fits.

Fits how?

Fredrick Thomas Willoughby,
33 at the time of the murders.

Came into the system
as the identified owner

of a white 1100, which he used to
keep round the corner of the house,

even though he had
parking outside.

Was the car taped? If it
was, there's no record of it.

But there's an old intelligence
report in the file.

Complaints from neighbours
that he'd approach kids.

"That's a lovely dress
you're wearing," etc...

Maybe he was just
a friendly bloke?

Maybe.

But his resemblance to
the witness description

was noted at the time, bushy
hair, thick moustache, well-built.

He'd apparently leave
his house of an evening,

but when questioned, his wife said
she had no idea where he went.

Do you look in the
Stop Check log?

Yeah, he crops up a few times.

Always driving his white
1100 late at night.

Stopped locally in
Port Talbot, Swansea

and on two occasions the Jersey
Marine to Llandarcy Road.

Christ, boys, we need to swab
him before we do anything else.

How? He's told us to f*ck off.
Well, he's told you to f*ck off.

Set up a meeting. I'll
work my magic on him.

This I've got to see.

I've got some
homework to finish.

All right.

Oi, plate.

Bloody hell.

I ran into Maria
in the supermarket.

Hmm.

She mentioned you'd
dropped your teaching.

Right. What else DID she say?

Nothing.

But I got the sense that
she was worried about you.

Well, one, she
needn't be, and two,

she had no business
conveying that to you.

Whoa, now, that was
only my impression.

Er, yeah...

Sita...

What is it?

Nothing. Just, er, usual.

Too much work, not
enough hours in the day.

Sure?

Yeah, sure.

I don't want Maria to get
it in the neck now, OK,

cos she didn't really say anything.
Oh, no, no. Don't be silly.

I overreacted. It's fine.

OK?

Yeah, OK.

Well, the good news
is, he will meet you.

He has conditions.

Bizarre, man.

It's full view of as many
people as possible. Clever.

Hello, Mr Willoughby.

I'm Detective
Inspector Paul Bethell.

I believe we've followed your
instructions to the letter,

please say if we haven't.

To cut a long story short,

we're trying to solve the murders
of three young girls in 1973.

Through DNA testing,

we're hoping to bring the
man responsible to justice.

But above all, we're hoping to
bring a degree of peace and closure

for the parents and families
the girls left behind.

Well, Mr Willoughby, I hope
I've put your mind at rest.

Can I arrange for my officers
to return at a convenient time

to collect a mouth
swab from you?

No chance.

Boss wants to see you.

Come in.

Sit down.

Detective Inspector Warren informed
me of your sensitivity at the scene.

He did?

Some imbecilic constable
allowed Mr Hughes into the wood.

Yes, sir.

And then you drove him home.

Poor man.

It's the least I could do,
sir. Well, in that light,

I think you're the man to go and
update Mr Hughes and his wife.

Important that they
feel... kept abreast.

What am I telling them exactly?

Keep it vague.

Talk about our general progress,

the dedication of the team,

the thorough nature
of the investigation.

Right, sir.

And if they ask for, er...

..examples of this progress?

Tell them - to divulge more would
be to jeopardise our inquiry.

What I'd like to emphasise is the
thorough nature of our investigation

and the dedication of our team.

Well, we appreciate you taking the
time to come and tell us, I'm sure.

I'm not sure Detective Constable
Bethell's told us anything.

Are you any nearer catching him?

We have several active
leads, Mrs Hughes.

To say more would
jeopardise the inquiry.

We understand.

Thank you.

I'll leave you in peace.

Thanks for the tea.

And er, tell Mr Allen
he needn't worry.

We're not gonna run
our mouths in public,

vent our frustration
to the papers.

I mean, that's why
you're here, isn't it?

We just wanted to keep you
abreast with our progress.

Right, well, next time you come,
let's hope you've made some.

Not that it'll make a
blind bit of difference.

So, how do we get his DNA?

What, surreptitiously, you mean?

Sorry, but I'm afraid the whole
idea is fraught with problems.

I'm all ears.

Well, if you followed
Willoughby into a pub

and nabbed his glass, say,
there'll be scores of DNA traces

all over the vessel and no
way to tell which is his.

And let's say he hadn't wiped
the sweat stains off your car,

and I'd been able to get DNA,

I would have taken
it without consent.

So it'll very much prove
inadmissible, Paul.

DNA's our new shiny toy.

We must protect it scientifically
and reputationally.

With respect, that doesn't fly.

You started all
this. You came to us.

Now it's getting a bit choppy
out there, you want to...

Play it by the book? You
bet I do, yeah. I have to.

All I'm asking is
you test his DNA.

And when I take that
DNA into a lab, any lab,

they're gonna want to see a warrant.
Come on, don't give me that.

Or some other supportive
legal documentation

that I will not be able
to furnish them with.

Where there's a
will, there's a way.

I know Willoughby did it,
I just need to prove it.

Yeah, you knew it was Dai
Williams, too, didn't you?

All right, you stubborn b*stard.

Find me a way that won't sully
DNA's good name or yours.

All right, such as?

I've no idea, Colin, I got
a D in O-level Biology.

I bet you bloody didn't.

Night, Paul.

Geraint?

You've been summoned, boss.

High-ups need a progress report.

Right, it's been three months.

Where are we? Briefly.

Yeah. Well, sir, we've no
positive results from the swabs

but we have a strong suspect.

A man who was living in the area
in '73 and resembles our e-fit

and is refusing to provide
us with a DNA sample.

How many men have
you swabbed to date?

Sorry, sir, did you
hear what I just said?

Said?

265, sir.

Yeah.

I'm afraid we'll have
to start thinking about

a cut-off point as a date.

I think mid-January
would be sensible.

Sir, I've got a suspect who's
refusing to give us his DNA.

And I've got to consider the
drain on day-to-day resources

in the light of historically
harsh budget cuts.

We completely understand, sir.

And we'll do everything we can
to bring a charge by mid-January,

if not before.

Good evening. The
relatives of four young men

are in mourning tonight
after an horrific accident.

The four were in a car which plunged
into the River Usk near Newport.

A fifth man managed to escape
and swim to the river bank.

He's been released from
hospital after being treated

for shock and hypothermia...

HGV can reveal tonight that one
of the four had previously...

It's all right, Dad,
I've got it. I've got it.

You've got physio
on Friday as normal,

but it's not with Gemma
because she's on holiday, OK?

Now, sit down.

OK?

OK.

We need to talk
about the house, Dad.

Do you remember I said...

..we need to start
clearing it out soon?

I was thinking of making
a start next week.

OK?

Yeah?

We have to work out
what we're gonna keep

and what we're gonna throw away.

Don't worry, I'll
sort it all out.

Sita?

Why did you think you
always knew best, Dad?

Always!

You never asked
me what I wanted.

You just tried to control me
the way you controlled Mum.

Why did you have
to come that night?

Why?!

Why did you make me leave them?!

Oh, God, sorry.

Oh, I'm sorry, Dad.

I'm sorry. I'm sorry.

I'm sorry, Dad.

I'm sorry, Dad.

It's all right bach, it's OK.

Why don't we have some
water, some paracetamol?

I had a B in O-level
biology, actually.

Oh.

Commiserations.

I've been speaking
to a colleague.

I really think we need to
roll the dice on this, Paul,

think laterally.

I told YOU that.

50% of the k*ller's DNA
would have been passed on

to any children he may have had.

Moreover, he has a
distinctive genetic marker,

which also would have been
passed on to any offspring.

Mm-hm, a double allele.

Rare-ish.

I could search for individuals
with the same feature.

Vast.

So initially I would focus
on Port Talbot and Neath.

All right, go on,
I'm interested.

Well, you should be interested.

If we're successful,
we'd be making history.

Familial DNA has never been
used to identify a suspect.

We'll be going where no
man has ever gone before.

Not to strike a too mundane note,
what about my suspect, Willoughby?

Well, if his male relatives
are on the database, then, yes,

we may well get him.

And if I put in the double
allele into the database

with geographic parameters...

Yeah, but those parameters,
I mean, they're guesses.

Oh, that's harsh. This is based
on a statistic that 80% of K*llers

live within a four-mile
radius of the m*rder scenes.

Still guesses.

I did say that we'd be rolling
the dice on this one, Paul.

Go on.

My search could yield a shortlist
of around about 50, say.

What do you think? Achievable?

Very f*cking achievable.
