Silent Witness (1996) s19e05 Episode Script

You OK? It's all right to feel afraid.
It's all right to feel anything.
I'm here for you.
I see it's catching, my paranoia.
You're safe, Paul.
Trust me.
We talked about pushing yourself, getting back out there from the start.
You're so sure about this, aren't you? Yeah, we are.
Only takes one person to recognise me and I'm screwed.
DOG BARKS Doesn't mean you can go on holiday.
Paul's got a future.
Paul can have the life he wants.
Why are you smiling? You.
All those years, "Tell the truth.
"Face the truth.
" Now you're teaching me to lie.
It's just me.
You can't be here.
What do you think you're doing? Hmm? Why don't you answer the phone? You're a mess, you need help.
You said you'd help me out.
I ain't doing that again.
You want people here knowing what you did? I'd never, I'd never! Please, help me.
Please.
You said you'd get me the drugs.
I'm sorry, I'm sorry! KNOCK AT DOOR Thanks.
Superintendent Clive Mitchell.
Lyell Centre, Nikki Alexander, Jack Hodgson.
DI Snow.
Not often we're met by the Super.
Not often we get one like this.
David Sellars, 31.
Multiple wounds to the torso, forearms, hands, neck.
Forehead and scalp also.
Is there a weapon? No.
Time of death most likely 7.
45 yesterday evening.
That was fast.
Huh.
We'll verify, but with wounds like this, attack and death won't be very far apart.
It is odd, though.
What's odd? There should be way more blood.
Excuse me.
HE SKOOSHES A SPRAY Someone's tried to clean up.
Is this his place? Tenant.
Let's owned by the probation service, they've got several units on this estate.
How long has he been out of prison? Six months.
What was he in for? He did 12 years .
.
for killing his mother.
The kid who used to dream is still in here, but I just stopped believing it.
Cocaine, vodka, cash, being the man, being feared.
Took a long time to learn it's OK to be afraid.
Being in that club .
.
watching my girl get hit on, those two touching her when she never wanted it I chose what happened next.
I chose to follow them into that car park.
I could've walked away .
.
but I took a baseball bat .
.
and I ended their lives, ruined so many others.
You never pay back what you did, never goes away.
Only evil is to admit nothing, deny.
No-one here's doing that.
Everyone here has taken a life, so a life licence gives you the chance of a new beginning.
I believe that earns you the right to dream again.
It worked for me.
Watch that one, though.
She'll do your head in.
LAUGHTER All right, mate, cheers.
That was really helpful, thank you.
Nice one, mate.
Cheers.
Don't make me do that again.
First time back is tough.
Problem share's a pain in the arse, didn't you teach me that? It's always good that they hear it from someone who's been through the system.
You were brave, we were listening.
Maybe I should branch out - kids' parties, weddings.
Erm Well, I ain't going to light it.
You've been a good support to Ben, and really positive.
He's done all the hard work.
With your help.
PHONE BUZZES Excuse me.
Sasha Blackburn, Origins Centre.
Yes.
I'll be there.
Sasha? It's David.
torso, neck, face.
Further incised wounds to the palms and arms.
He was probably struggling to defend himself for most of the attack.
Wound orientation and grouping suggests a rapid assault.
Slim blade, probably a knife.
Single edge, non-serrated.
Both forearms show multiple keloid scars.
Mm, some of the worst I've seen.
Some of them are still healing, suggestion of prolonged self-harm.
Or abuse.
Mm.
Also evidence of heat damage to the dermis.
It's branding.
David marked himself every year, his mother's birthday.
This is Dr Blackburn, forensic psych attached to the Origins Centre, the lifers' rehab unit Sellars attended.
His feet are abraded and lacerated.
David suffered from schizoaffective disorder.
During bad episodes he'd often go barefoot, hallucinate.
Was he in the middle of a psychotic episode? He wasn't stable.
The last few weeks, I'd been seeing him regularly.
I was pushing for a hospital stay.
There's a callous on his lower shin.
Did he wear an ankle tag? He didn't have one on? He must have taken it off.
He had consented to GPS monitoring.
Some prefer that to daily signings or police visits.
Can we get that data, please? Yeah.
Nikki have you ever seen that before? No.
Small intestine, it's the wrong colour.
It's bright purple.
I was a prep cook at a university.
It was a big kitchen, like a canteen, erm, for students.
Can you use a fry tank? What? No, I did breakfasts, mostly.
Worked on the cruise ships two years.
Where did that take you? The Mediterranean.
Catch anything I should know about? I'm winding you up.
We use a candidate verify service.
Background checks.
You're alone with a till.
Unless you're an armed robber, you'll be fine.
You Mill Wall or The Addicks? A South London boy, not into your football? to life for the murder of Mary Sellars, his mother.
Judge set minimum term of ten years, Sellars served 12.
So there were problems inside.
He started off in secure hospitals.
When medication stabilised him, he improved.
Moved to prison, where I helped with his rehab.
He struggled but tried really hard.
He was released on licence last year.
David stabbed his mother with a fire poker which he heated first, yeah? Correct.
How did you find him? Regarding his offence? Yeah.
Remorseful, lucid.
On medication, David was capable of objectivity, good judgment.
His psychometric scores improved year on year.
I had no evidence not to recommend him for release.
And what was behind his recent relapse? It's difficult to say.
Just stopped communicating.
Main reason I was considering the section order.
Without meds, people with schizophrenia can become unstable.
On rare occasions, violent.
But they're all extremely vulnerable.
Right, no weapon yet but the clean-up job seems odd.
Frenzied attack, the killer sticks around to mop up and has the presence of mind to dispose of the cleaning gear.
We're doing a deep search for the murder weapon.
We need to widen the net for DNA.
I'm on it next.
Swabs from all the residents.
Interesting career choice, spend your day with the most violent men in the country.
Whereas our job's entirely free of unresolved personal issues(!) So, purple intestine's calling me.
Thomas.
All right? He was attacked in his flat.
I know you were close in Redhill.
I'm sorry.
They know who done it? Not yet.
Where are they burying him? It don't matter, does it? No-one will be there.
I won't be there, will I? We used to joke who'd have the emptiest church, him or me.
I'll be there.
Yeah, you don't give up on anyone.
Look, I know it's really hard, but you have to focus on your progress.
I am.
I spoke to the agency and they said that you walked out of your job interview.
He smelt me out.
He knew it was bullshit, it's all bullshit.
Paul.
Paul! You don't get it! The things we've done, they don't go away.
No, we just run from it.
SHE SIGHS DOOR CREAKS Four o'clock, Marcus.
Always better the prison governor's on side.
We can move that one there.
That one, yes, that'd be Hi, Sylvie.
You're not so hard to find.
Our boy's name's right above the door.
Had a drink today, Ted? Is that your business any more? You're in my office.
Is Connor here? So you've heard, then.
He's out, Sylvie.
I was going to call you.
Yeah, I can see you're busy.
They told me I could have some counselling, it'll help process my feelings.
What do you reckon? Maybe you could get me together with Joe.
Try to forgive.
Never forget.
You should talk to someone.
What if I found out where he lives? Still got some old contacts.
We met some good coppers, didn't we? You promised me you'd do nothing to him.
Ever.
When I still loved you .
.
you promised me.
Promise me again.
Now.
HE CLEARS HIS THROAT I know you're in there, Connor, lad, I know you are.
I just want you to know I respect your decision to ignore your father for almost six or seven years, totally respect that.
Free country, especially if you're Joe Sherringham.
Do you want to be here when the police arrive? I don't have any photographs of him any more.
Can't .
.
of my little boy.
How can you bear to have them? Just have him look at you, every day? How can you do that, Sylvie? I was going to tell you.
I'm sorry.
Forensics, right? Yep.
One of your guys said it's a right mess up there.
Did you get anything? And you are? Ryan White, warden.
I was on the force, two years.
I told your Super I'd help if I can.
Two years? Not long.
Paper worker.
I wanted to be on the street, making a difference.
Has the graffiti been going on long? A few months.
This is a decent community.
There's a few ex-cons, lifers - God knows what they did.
But probation says they're safe, so Is that anything to do with all this, the paint? It's probably just kids.
I'll need a swab from you, for the record.
Anything I can do.
Do you want a cup of tea while you're at it? Tea or coffee? Tea, please.
That spray paint's a nightmare to clean off.
Yeah, it must get all over you.
Can I use your bathroom? Sure, it's downstairs.
Thanks.
Yellow paint.
Blood.
Someone's been busy.
Do you take sugar? TOILET FLUSHES Text from the office.
Sorry, got to go.
Snow? It's Jack Hodgson.
I'm outside flat 63, the warden, Ryan White.
There's blood in his bathroom - better get down here.
Oh, shit Man, I hate it when they run! Stop, police! Get up! Clarissa, the discolouration we noticed in the intestine, anything yet? SHE SPEAKS BULGARIAN What? It's Bulgarian for cow.
Really? Bovine diazepam.
They add a purple dye to show it's unlicensed for human consumption.
This batch was manufactured by a chemical company in Gabrovo.
The deceased probably got it illegally online.
Much like my fluent Bulgarian! Don't worry, I'm all over it Shef.
Sorry I'm late.
Hey, it's your mum! Hey.
Mum! He scored twice.
Twice? Max, that's brilliant! We thought you were going to be there.
I'm sorry, sweetheart.
I'll be there next time for your hat-trick, I promise.
OK.
He was fine.
It's you I'm worried about.
Since the divorce Mum.
Why don't I cook tea? Let me just Let me just get rid of all this.
PHONE RINGING Hi, it's me.
We found aerosol paints on your clothes.
Matches paint found outside the victim's front door.
Yeah, a can went missing from my workshop a few days ago.
There are also traces of blood in your bathroom and on your trainers.
David Sellars' blood.
Why did you wash your trainers, Ryan? I don't know anything about blood.
Then, why did you run? I panicked.
I asked that forensics guy back to my flat.
Why would I do that if I'd just murdered someone? The probation service use some of those flats for ex-offenders.
How do you feel about that, having ex-cons in your block? Nice flats, all paid for.
Everyone deserves a second chance.
You haven't had many yourself, though, have you, Ryan? Eh? I mean, the police force didn't want you.
It seems you expressed some pretty strong views at interview.
Life should be for life, police's hands are tied.
Then, you got divorced soon after, so no second chances there, either.
How often do you see your kids now that Mary's moved to Scotland? She never applied for a restraining order, so you're not denied access.
Don't you want to see them? Or don't they want to see you? Hard for any father, that kind of rejection.
Do you know what that freak did to his own mother? Yeah.
And now I know you did too.
Failed marriage, failed cop, prejudiced, the aerosol, access to the flat, fled the scene.
Not a big leap for the jury.
I went up.
I wanted to see him, wash the graffiti off again.
And I saw You cleaned your tracks.
Why didn't you just call the police, Ryan? I wasn't thinking straight.
I thought if someone knew about the graffiti, if they saw my footprints You can do me for that if you want, but I never killed him, I swear! Tell me you got something new.
We can't hold Ryan White much longer.
We tracked the tag that David Sellars wore up until last week.
Yeah.
Most days he never left his flat, but two weeks ago, he made quite a trip.
Yeah, right across town.
What's this? Residential flats.
He was outside one of them for three hours.
Waiting for someone? Yeah, check the occupant.
If it's good, bring him in.
Sir.
KNOCK ON DOOR Paul Raynott? So, this is your idea too.
What, to use full resources? Absolutely.
Where's the suspect? He's not a suspect.
We have a person of interest.
On his consent, we'd like to do some tests after interview.
Sorry, during which you intend to bring up the matter of his identity.
Are you serious? Absolutely.
Then, these people do not need to be here.
My client's safety means he's a very vulnerable case.
Who's the client? Look, are we part of this investigation or not? How can we contribute unless we know who and what we're dealing with? Excuse me.
DI Snow will be taking notes.
Should I have a lawyer, then? You're not under caution, this is a witness interview.
You understand why you're here.
What would you like me to call you? Paul.
Do you know why you're here, Paul? David's dead.
Describe your relationship with David Sellars when you were both at Redhill.
He looked out for me.
Not many did.
When did you last see him? Ages ago, inside.
So, no contact since, of any kind? This is a record of a journey that David Sellars made three weeks ago.
He visited your address.
Can you tell us about that? I don't understand that.
Did you see him that day? No, never.
How did he know where to find you? I don't know.
Your new ID, address - that's all highly-protected information.
How did he know where you were? Paul answered the question.
I know you're Joe Sherringham.
A child killer.
Joe Sherringham? A willing participant in one of the most notorious child murders in recent history.
Craig Blake murder.
Since release, you've been on daily signing with probation.
You've been late for some of these.
I lose track of time a bit, it's only happened twice.
Tell me where you were last night between 7pm and 10pm.
I never killed David.
Just answer the question, please.
In my flat.
Can anyone confirm that? No.
I was on my own.
Can't imagine anything more lonely.
Living with your secret.
Pretending to the outside world that you're something you're not.
Superintendent Of course you needed a friend.
Someone who knows who Paul really is.
But then, he became a liability.
You felt sorry for him, but you couldn't help Please be quiet.
Must have been very, very scary.
Thinking about what he could do.
What he knew.
What would Joe have done? What would Joe have to do to stay safe? Joe wouldn't be scared.
Stop this interview! I'm not Joe any more.
I've done nothing.
Did you see how he looked at me? Proper copper that one, innit? I know that look! He thinks I'm a monster.
Is there anything you're not telling me? Because now's the time.
Did you contact David? You don't believe me.
Will you just come and talk to Probation.
See, I know what's coming.
What do I have to do? I'll do it.
Daily signing? I'll do curfews, tag me, I don't care.
Not prison, a safe house.
You come and go, I will see you every day.
This is them, they want this.
Paul, it's about what's best for you.
Then, arrest me.
Cos I ain't walking back in, no chance! PHONE RINGING I need Paul Raynott's offender manager.
I've just spoken to Probation Services.
The day David was trapped, Paul was with his offender manager all day.
They never met.
But the day he was murdered, David took off his tag.
There could've been other times.
There's no proof.
Are you going to charge him without it? I appreciate you're very invested in Joe's rehabilitation, but the truth is there are no certainties yet.
Ryan and Joe could both be in on this.
I'm overinvested here? You are prejudging a very sensitive, very insecure young man.
HE CHUCKLES You know, I knew officers on the Craig Blake murder.
When it was done, they both took early retirement.
My age, fit, years of service ahead of them.
But after that one, they'd had enough.
What happened in that building in the woods what Joe and Marcus did to that Blake boy - they'd seen enough.
Have him sign the notes, get his permission to search his flat.
If you've got any fear that he'll run, I'm the first to know.
Agreed? INDISTINCT CHATTER What you looking at? Yeah, I killed Craig Blake.
I'm Joe Sherringham, I killed him.
Now, look at me, I killed Craig! Sick tosser! It is Sellar's blood, yeah? Some.
But these shoes should've been drenched in it.
DI Snow found this in a storm drain outside David Sellar's block of flats.
Fantastic.
Yes, we'll get onto it.
The attack on David.
It required strength, determination.
Over 60 blows, that's around two minutes of repeated stabbing, forceful enough to go through bone an inch thick.
So? Ryan's threats were anonymous.
He wanted to avoid confrontation.
The profile doesn't fit.
And there's more good news.
The wound pattern on David suggests a right-handed assailant.
Let me guess.
Ryan's left-handed.
So, for now, Ryan's story holds.
Went upstairs, saw the blood, panicked, cleaned up.
And we can't prove that Joe Sherringham met David Sellars that day either.
No.
OK, we'll go back and make enquiries about any contacts David may have had outside or inside prison.
Sorry.
Right, can you access the hard drive on this? I can.
Since you asked so nicely.
I'm looking for trashed e-mail, social media, deleted internet activity.
Who's the user? Um, Paul Raynott, aka, Joe Sherringham.
Anything you find, run it past me first.
Understood? I'll run it any way you like.
It was a road rage incident.
Business wasn't going well, was drinking.
When the other guy came at me, yelling, I took the wrench and I just I lost it.
I've been out ten years now.
There were anger management issues, obviously.
I realised that later.
And that's where you met David Sellars.
Yeah, he was on a reoffending workshop that I helped on.
I didn't know him well.
I think Sasha was very concerned about him.
He needed more and more of her support.
We found graffiti outside his door.
Has he ever mentioned that he was being threatened, intimidated? No.
Did he talk about wanting to reduce his dose? We're lifers, Superintendent, we can be recalled at any time for almost anything.
David had three weeks before he could move into his own house.
I can understand why he wouldn't want anything to get in the way of that.
Hi.
Hi.
My wife, Mandy.
Oh, thanks.
She doesn't normally do the coffee.
She's the real boss round here.
Kept the place going while I was inside.
Can you tell me where you were, evening before last? At home.
We went up about 10.
30, after the news.
Like we always do.
I'm also on licence.
Bennet Walker.
He attends the Origins Centre as well.
Yeah, I helped him through his first few months on the outside.
He needed a job, it was cleared by probation, so I'd like to talk to him.
Er, you should know that his colleagues are not aware of his past.
Is Ben in any trouble? I just need a word.
You were a bit of a bad boy, weren't you, Ben? Gangs, drugs, bit of dealing.
Mm.
Got life for murder.
Couple of guys chatting up your girlfriend.
That was then.
So, tell me about you and David Sellars.
Who? HE CHUCKLES You were in Redhill at the same time.
Oh, right, Sellars.
Bit of a schizo.
You attacked him in the canteen.
That was nothing.
It was an argument over a portion he give me, that was my first month inside.
Right.
Before you turned that corner.
Bought into the rehab workshops and classes.
Ten years, got yourself out on licence.
They don't let us out easy.
Whatever the papers want you to think.
Thing is, there's always that question, isn't there? Have you really changed? Oliver texted me.
Why didn't you tell me you wanted to interview my clients? You have a problem with that, Dr Blackburn? Have you seen David Sellars since you've been released? No.
What's this about, Sash? David Sellars was murdered two days ago.
Where were you that day, between 7pm and 10pm? Oh, right.
I get it.
Pull another lifer in for it.
Yeah? Easy collar, statement to the press, all done and dusted, huh? Just answer the question.
It's important, Ben, whatever you know.
I was at the gym and then, I went home.
I'll be on camera all the way.
Why don't you go and check? Why was David killed? They don't know.
I'm so sorry.
Are you OK? I'm fine, Oliver, really.
You weren't responsible for David.
You're looking after everyone except yourself.
There's people around you who can help.
Look, I've really got to go.
We've got David's tox reports.
They confirm that the anti-psychotic that he was prescribed was present, but at much lower levels than expected.
It suggests that he was reducing his risperidone, using bovine diazepam to try and replace it.
Do you think he was self-medicating? David spent all his adult life in jail.
Told what to do, what to think.
Self-medicating is a way of taking back control.
He just wanted to feel normal.
We knew he was struggling.
He needed more and more of my time.
I knew that there was a chance he was letting his meds slip.
David trusted us, and we let him down.
What makes you want to do this? Making these impossible calls? Almost all the lifers that I deal with have also been victims.
Abuse, neglect, just no chances in life.
Most want to turn things around, they just don't know how.
And I am in a job that can help them.
How can you know if they've really changed, if they're safe to be released? We look for the science, patterns, tests, observation.
We do our best with the evidence that we have, just like you.
Do you lie awake at night, wondering if you made the right call? Do you? I believe everyone deserves a second chance.
CLICKING LIGHTER CLICKS There's nothing worth nicking here, mate, I swear.
Hello, Ted.
I used to come round here when Dad was drinking.
And you'd patch me up, let me stay over.
I want you to know I never wanted to hurt Craig, I swear.
But you did.
That's exactly what you did.
I didn't know who I was.
I had no-one at home to show me, just you.
And then, Marcus came.
And he He could see I was wide one, some messed-up kid.
Right, so you're the victim? Huh? Not my little boy.
Is that what you learnt in prison? I came to say I'm sorry.
I'm so sorry.
I know it doesn't mean anything, but It's just too late, but I just wanted to say it.
Do whatever you want.
Come on, Ted.
Come on, do it.
Do it, I wouldn't blame you, do it! KNIFE CLATTERS TED SOBS I'm so sorry, Ted.
My new name is Paul Raynott.
I live at Flat 9, Endicott Place.
So now you know.
DOOR OPENS DOOR CLOSES DOOR CLANGS MAN: Breakfast call, Marcus.
VOICES ECHO Traces of David Sellars' blood, the blade matches the wounds on his body.
No prints or DNA from his attacker.
Meanwhile, Joe Sherringham's laptop tells us he knows a thing or two about encryption.
Masked IP addresses, proxy servers.
So it took a while, but ten days ago, he got this.
An invoice for 50 diazepam.
Exactly the same chemical profile as the ones David Sellars was taking.
Sellars tries to make it without his meds.
His mental state deteriorates.
Asks Sherringham to get the diazepam for him.
Ends up dead.
I'm pulling Joe Sherringham back in.
Going to keep this low-key, OK? Jack.
This what you call low-key? Jason.
Badly burnt male.
Found outside the front of the property.
Alive, just.
Fire crews found a body in the kitchen, we're just waiting for the fire investigators.
This isn't Joe Sherringham.
No, but this is.
Looks like multiple stab wounds to the face, neck, upper torso.
Same as David Sellars.
Possibly.
Weapon? Screwdriver.
Under the body, protected from the heat, about the only thing in here that was.
This little baby is the seat of the fire.
From the spread pattern and the burns on the fellow outside, I'd say an accelerant was used.
Boss.
Hospital's got an ID on the burns victim.
It's Ted Blake.
Ted Blake? Father of Craig Blake.
The kid that Sherringham murdered in the woods.
So, did Blake find out where his son's killer lived, set the fire to cover his tracks? Got caught as the accelerant ignited, staggered outside, collapsed.
Maybe this felt like some kind of justice.
Hard to live with, a loss like his.
Sherringham's new ID was Class One protected.
I want Blake's last movements, contacts, the lot.
I want to know why and how he found Joe Sherringham.
Sir.
Tell the hospital to isolate the suspect.
And, Snow I want the press out of this for as long as I can.
Why would Ted Blake also kill David Sellars? He wanted payback for his son, maybe got to Sellars first, forced him to spill Sherringham's address, then killed him.
How did he find them? Well, we know that Sherringham met Sellars and gave him diazepam, maybe they were seen together and someone tipped Ted Blake off.
We need Ted Blake to talk.
Is he conscious? They won't let us near him.
You're a doctor, right? No.
This man is a murder suspect.
Right now, my patient has burns to over 40% of his body.
I won't risk exposure to further trauma.
I'm sure you realise the implications of this case.
My job is to keep him alive.
I'm sorry.
Er, Dr Chamberlain, Lyell Centre.
He has an endotracheal tube.
Was there respiratory distress? Oedema of the oropharynx.
Possible hypoxia.
Hypoxia.
So, you've taken bloods.
Give us something to work with till we can examine him.
I'll tell Path to expect you.
And his clothes are bagged.
What's left of them.
I've come to see my husband.
Mrs Blake, I'm Superintendent Clive Mitchell.
I know this is a really difficult time, but I do need to ask you a few questions.
Can't you wait? He came to the office yesterday.
He'd been drinking, I just wanted him out.
Did he ever talk about wanting to find Sherringham? All the time.
Dad used to bang on about revenge.
What he'd do to Sherringham and Chadwell if he ever got the chance.
We just We just thought it was drunk talk.
Any idea how he learned about Sherringham's new identity? I got back up on my feet.
Built something positive from my son's death.
Tried to forgive, never forget.
Ted's just made that a sick joke.
JOURNALISTS CLAMOUR It's all starting again.
We're never going to be free of this now.
The blood is all Joe Sherringham's.
No surface traces of the assailant.
Look for sweat or epidermal samples under the handle.
Start where the shaft and the handle meet, work your way down.
So, those are my plans for the evening.
You? Oh, the usual.
Cup of cocoa and straight to bed with a Jilly Cooper.
Did you get the mass spectrometry on Blake's clothes? No sign of accelerant.
Really? Well, maybe we're looking at fast evaporation, LPG, aerosols, lighter fluid.
Maybe, but I can't find any blood on Ted's clothes either.
With that kind of attack you'd think we'd get something.
You set alight to a crime scene to obliterate traces, right? But Joe Sherringham was attacked and killed in the kitchen.
So, why set the fire in the hall? Absence of soot in the mouth and pharynx, indicative of death before the fire.
An examination of distal airways to confirm.
Stab wounds to the chest, neck, upper arms.
Angles of entry and spread suggest that they were made while the victim was moving in relation to his assailant.
Multiple deep stab wounds to the face.
These seem to have been made after he stopped moving.
I don't think this was just a frenzied attack.
This was mutilation.
Someone wanted to dehumanise Joe.
Erase his identity.
Why? There's no ritual element, as far as we can see, there's nothing sexual.
Because then, he'd be removed as an obstacle.
He wouldn't be in their way any more.
Two different types of murder weapon, a knife and a screwdriver.
But there are similarities in wound pattern.
In particular, a deliberate targeting to the face.
In Sellars' case, less pronounced.
The facial wounds are fewer and shallower.
So, the killer's work on Sherringham could suggest a development.
His anger's finding its expression.
More focused.
We know Ted Blake was in the vicinity, but so far we've got nothing to connect him to the actual murder, or, indeed, to setting the fire.
No, you told us there were flash burns on Ted Blake.
Yes, but there's no trace of accelerant on his clothes and we would've expected at least some of Sherringham's blood to show up.
So, we've got nothing.
What happens if there was a third person? Possible.
Pull up the file on Joe Sherringham and his victim, Craig Blake.
Gov.
Anything on the screwdriver? Small traces of skin on the handle.
Luckily, Sherringham's blood didn't get in there or swamp them.
PHONE BUZZES I'm expecting the DNA back soon.
Blake's conscious, he's trying to talk.
I'll come with you.
MONITOR BEEPING SUSTAINED BEEP Sats are dropping.
Bringing the defib just now.
Got a cart.
Ted! Sir! You need to move out of the room.
Sir, can you move back? Still falling.
TV: 'It appears Edward Blake was caught in a fire that destroyed 'the flat where Joe Sherringham was living.
'15 years ago, Sherringham and an older teenager, Marcus Chadwell, 'received life sentences for the murder of Blake's son, Craig.
'Sherringham had recently been released on licence with a new identity, while 'Marcus Chadwell remains at a high security unit at Oakford Prison.
' Ted Blake's dead.
Really? This came from Mitchell.
The pathology from the Craig Blake inquest.
Thanks, Clarissa.
I'm here all night if you need me.
When do we get Blake's body? Be with you later today.
What's the news? Targeting the face is an uncommon style of violence.
But look at this.
15 years ago.
Among Craig Blake's many injuries, there were a dozen puncture wounds to his face.
Joe Sherringham testified that they were inflicted by Marcus Chadwell.
Marcus never admitted this.
Well, he's never admitted anything.
Maybe Marcus doesn't want his second chance.
It's rare, but it happens.
He's never shown remorse for what he did, he's refused all rehabilitation work.
On both Sellars and Sherringham, we suspect that these wounds were inflicted when the victim was motionless.
At the Blake trial, the prosecution suggested Marcus did something very similar to Craig Blake.
All right, is it possible that Marcus Chadwell coerced someone else into killing both Joe and David? This third person? Surely we have to consider the possibility.
When one of the victims is Joe Sherringham.
Marcus's contact with the outside world is closely monitored.
Yeah, but he's associated with other prisoners for years, some of whom have been released.
And he's highly manipulative.
Psychopathic personality types always are.
He manipulated Joe into killing Craig Blake.
But? Two things.
If Marcus influenced someone inside to go out and kill, then we missed it.
Given the tests, the therapy, the scrutiny that lifers undergo, it's unlikely.
But it could happen.
It would take a uniquely deceptive personality to hide their true psychology over time.
Marcus is a uniquely deceptive personality, so what's the second thing? You've seen the TV.
Marcus Chadwell is famous again.
You give him the attention of a police investigation on top? He WILL play games.
He's been dreaming of this.
You understand why we're here.
Ted Blake and Joe Sherringham.
Yes, how very unfortunate for them.
We've not been introduced.
I'm a forensic pathologist.
So you're the one digging up the past.
Can you tell us anything about these wounds? Hmm.
I don't have a lot to say about this.
Do you? Judging by the concentration and patterning, he wasn't conscious when they were inflicted.
And that's your conclusion? Is it correct? Well, you seem quite confident.
What do you see there, Marcus? I see Craig Blake.
Recognise the photograph from the trial.
Have you discussed Craig's wounds with anyone else? Who do you have in mind? Somebody who you felt comfortable talking to.
You looked after Joe, didn't you, Doctor? Strange how inseparable we became.
You were very different.
How was Joe under your care? Joe was a very brave young man.
I'm not very interested in Joe and I'm not, it turns out, very interested in you.
Evidently, you're here because you need information from me, yes? If that is to happen, then, we would need to discuss someone that I am interested in.
Who are you interested in, Marcus? The mother, of course.
Sylvie.
Sylvie Blake.
Things happened that day I've not spoken about, things that impact on Joe's death very directly.
Are you claiming influence over these murders? Influence - that's a very good word.
He's being evasive.
I can tell you who killed Joe.
We need to take Sylvie to the building in the woods.
INAUDIBLE CONVERSATION Puncture wound, made by a small, blunt object.
WE haven't been able to match it with anything in the house and it wasn't made by the murder weapon.
You shouldn't have come here.
I'm not mad at you, mind.
I'm going to bring him out now.
He's not going to get anywhere hear you.
Where were you the day that Craig died? Why are you asking me this? I want you to check for a match.
Right, Ted Blake, I'm on it.
Not Ted.
It can go wrong for people like us.
Don't put your hands on me! SHE SOBS
