Silent Witness

The victim is Laura Jennings.

A swimming instructor at the local pool.

Ron Radford was Laura's ex. He's the one that abused her?

You should have said that he was ex-police.

She was pregnant. About six weeks.

I'm on an online sperm donor site.

I'm doing nothing wrong.

You're my garden angel.

This is Cara.

"I'm looking for your brother.

"He's my dad."

A daughter? Could you do a DNA test for me?

You don't know she's mine.

You don't know she isn't.

Tim Garrick. Laura researched the hell out of him.

Address, workplace, school.

It turns out his wife was reported missing two years ago.

I think we've found Joanna Garrick.

There's something else here.

Could be another body.

The body of the female is in a state of decomposition.

CAMERA CLICKS

Evidence of blood stains.

Potential site of entry wound.

Looks like a single stab wound.

We have what appears to be a dark pattern mark

on the male body's face.

Possibly a full-thickness burn.

What is it?

I don't know.

If there are any burns, residue of carbon?

In areas beneath the clothing,

decomposition appears slightly delayed.

We have a similar pattern mark on the right hand.

The dark deposits in the upper airways and trachea -

I think it's charcoal.

She's got a pacemaker.

Do we know if Joanna Garrick had a heart condition?

So pacemakers store data about heart rate and stress patterns,

like a mini computer.

So if this had enough memory,

it should show all event information,

up to the point of death.

Even a time and date.

OK. What am I after?

Something metal.

Like a grid about an inch apart.

Like a grill?

From a barbecue?

Mm-hm.

If he was pushed in headfirst, burnt his face,

puts his hand out to try to stop it?

His airways could have swollen.

Death by inhalation of hot gases.

Thanks, Jack.

Nice work.

DYLAN ROARS AND TOBY COMPLAINS

Ssh! Kids, your daddy's working.

You'll give him a headache. SHE CHUCKLES

Who's giving me a headache?

ME! ME!

Wasn't she the one from the swimming pool?

No, don't think so.

Is the man coming back?

What man?

The man at the shops.

What happened at the shops?

Somebody helped us with our bags. That's all.

It was nothing.

My dinosaur killed his cat.

Did he?

You be good for your mum now, OK? OK.

I did see the man.

Where?

What's cooking?

I'm pretty sure it's human.

Well, the Garricks' dental records are in and...

Cara. What are you doing here?

Sorry, Nikki. Adam?

Oh, it's-it's not what you think.

Paedophile? Who's a paedophile?

Oh, my God, no, no, no. She thinks Ryan's a paedophile.

He's not. He's not.

No.

HE SIGHS Er...it's complicated.

He arranged for another man...

..to have sex with a 15-year-old girl.

What happened to the girl?

She died.

It wasn't Ryan...

..but it happened because of him.

"I never want to meet him.

"Who wants a father like that?

"He's scum." Cara... Cara. Please.

Cara! Cara! Cara!

I didn't know how to tell you.

I'm sorry.

Our female victim's most likely cause of death

was the penetrating wound to the abdominal aorta.

Now, as far as we can tell, given the condition of the uterus,

her os appeared nulliparous,

which means that she hasn't given birth,

which fits with Joanna Garrick's medical records

of three failed rounds of IVF.

But...there's no mention of a pacemaker

or any issues with her heart.

So it's not her.

Well, I couldn't initially say that for sure.

There's always the possibility

that a pacemaker was fitted in an emergency -

maybe the hospital didn't forward the information.

But the Garricks' dental records just came in.

Now, this is an X-ray of our female victim,

and this the male.

That's not Joanna Garrick.

And he's not Tim Garrick either.

Then where are the Garricks?

Why was Laura at their house?

And who are they?

We don't know,

but every pacemaker has an individual serial number,

which is usually on the patient's files.

I've contacted the Danish manufacturer

to find which hospital it went to.

We'll find out who she was, and that should help with him.

Thank you.

How can no-one miss them, eh?

PHONE RINGS

Right. I'm heading back now.

When was this?

She's a teenager.

She'll come round.

Ryan doesn't want to meet her. Cara doesn't want to meet him.

She'll go back to where she came from and we'll never see her again.

Problem solved.

She's family.

I didn't even know she existed until a few days ago. It's fine.

Really?

Adam? Yep?

You're a Forensic Medical Examiner?

Yes. What's going on?

Frank Johnson's been attacked.

Frank the Wank? Yeah. They just identified him.

You ready?

Is there nothing he can't do?

Your blood pressure's rather high, Molly.

We need to keep an eye on that.

Don't want you having another stroke.

Dr Renn's prescribed antibiotics for the UTI.

Make sure you keep drinking plenty of liquids,

or you'll end up in hospital again.

I don't like your bedside.

Keep talking around the subject, Molly.

The words will come.

Table.

Make sure she drinks enough.

I'm still here.

My bonnie boy.

My chickadee.

I want my bonnie boy.

Not now.

I'm...

..kerplunk.

Broken ribs.

Skull fracture, extradural haemorrhage.

Acute bleed between the dura mater and the skull.

They operated to relieve intracranial pressure.

The artery on the side of his brain was bleeding.

He could have died.

Does he have any brain damage?

Is he going to wake up?

I don't know.

Significant bruising on the torso.

Distinct tramline bruising,

which occurs when struck with a cylindrical object.

Like an iron bar, or a bat?

Same on the arm, suggesting defensive action.

Probably trying to protect his head and face.

Mrs Johnson?

We met before.

I'm sorry about Frank.

Is there anything you can tell me about the night he was attacked?

I've already spoken to the police.

I'm taking over the investigation now.

He went to work. He didn't come back.

Were you at home?

Was anyone with you?

Rocco.

The dog?

I got into the shed.

I know what he was doing.

He lied to me.

All this time he said he didn't want kids.

But look what he's done.

Bastard!

I hope you die!

You bastard!

SHE SOBS

Blood spatter patterns show multiple blows, a dozen plus.

This wasn't a quick smash-and-grab.
