Silent Witness (1996) s22e10 Episode Script
Betrayal: Part 2
1 You think this one's suspicious too? I think everything and everyone is suspicious, Jack.
You know me.
Kalan Dhana.
Pujari Pharmaceuticals.
Was it my fault? I gave him the drugs.
BEEPING Shh! Hey.
Mr Pujari? Vail or Hodgson? Would you mind if we had a look around? Can I stop you? Would you want to? Young PC Steven Francis died as a result of the vicious assault he sustained at the hands of the two defendants.
You made a mistake.
I didn't make a mistake.
You have just said as much in open court.
You were wrong.
The Lyell's in all sorts of trouble.
This is the body of Steven Francis.
Caucasian male.
You better bring me the heart.
You didn't find anything.
No.
No, we didn't.
We're ready for the next stage.
One more trial.
Just to be sure.
Is this what killed Kalan? Tell me, or I go to the police.
See this? This is the body of PC Steven Francis, and this is the heart belonging to PC Steven Francis.
I did not make a mistake.
# Testator silens # Costestes e spiritu # Silentium Testator silens.
Can you pay them? I hate that bit.
I always feel I have to come back in the morning and pretend I've stayed the night.
I can't stand the humiliation of them knowing exactly what we've been up to which they probably know.
I'm just talking, waffling.
You are telling me the truth, aren't you, Amanda? About what? My marriage? Us? No, no, I don't mean about that.
The postmortem on PC Francis.
Thomas, do you think I'd meet up with you so you'd cover up No, no Is Nikki really so perfect that she can't make a mistake? One mistake? I'm sorry.
I should never What? Asked me that question or suggested we meet? This isn't about sex or .
.
the thrill of escaping this bloody job for an afternoon or an evening.
This is about love.
We love each other and .
.
that's why it had to end, and that's The problem is, you're the only person in the world I can share any of this with.
I know.
DOOR CLOSES Hello, Leon.
How do you know my name? You out early or are you often down this way? What's it got to do with you? Rumour has it you've got yourself a new phone.
No.
Who said I did? You can't see it, not with the naked eye, but there's a satellite up there and it's pointing down at you, and it's telling me you're using a phone that doesn't belong to you.
Bollocks.
Don't run, Leon.
Please.
I'm too knackered to chase after you.
But, fortunately, they're not.
NIKKI: This is the body of PC Steven Francis.
Evidence number LY-SF-63418 When was this taken? Keep watching.
.
.
This is the heart belonging to PC Steven Francis.
Evidence number LY-SF-63418.
Nikki, what the hell is going on here? I wanted to prove that my original findings were correct.
Who are you with? Who's taking the video? Look, Clarissa's printing out the results.
Results? What results? I took the samples to the laboratory myself.
I don't know what you're talking about, Nikki, but this is a serious breach of every single Nikki did not make a mistake.
Wait.
This has got nothing to do with what happened in court.
She took samples from Steven Francis's heart together with hair from his head.
The two samples have been DNA tested over the weekend, and wait for this.
The heart that you and Professor Long examined doesn't belong to PC Steven Francis.
You're joking.
You and Jack have checked every procedure we do here.
So have Chesham.
Nikki's original PM was with the right heart, but somehow a different heart was sent with the body or was swapped at Chesham.
What about Steven Francis's heart? Where's that now? Morning.
They've found Kalan Dhana's phone.
What did I miss this time? Continuing my interview with Leon Birchwood.
DC Vail, DC Nugent and the duty solicitor, Mrs Alvi, in attendance.
Where were we? What time did you find the phone, Leon? I don't know.
OK.
From the top, what time did you leave work? I told you, just after four.
And it takes you about half an hour to get home? Look, I was just walking that way, down the canal, because you lot took my driver's licence.
We took it, or were you three times over the legal limit when you were stopped and breathalysed? You had no reason to stop me.
Right.
You were walking home between 4am and 4:30am, and there was a blue sports bag left on some cable drums.
And a phone.
The phone wasn't in the bag? No.
It was on some cable drums? Just sitting there? Yeah.
And you didn't search the bag, pull out some clothes, and then find the phone? No.
Did this bag and this phone not belong to someone? Did you not think, "Ooh, that's odd"? Not down there at that time of night! All kinds of shit kicks off.
Look, Leon, I don't give a toss about the phone.
All I'm interested in is who you may have seen by the canal that morning.
You're going to think I was on something.
Other than your son's bike, you mean? OK, Leon says he was here.
It was dark, and he saw a phone and was looking at what else was in the sports bag.
Were the clothes in the bag? So he says.
Leon then heard a noise - some people by the water's edge - and in the water he saw two candles floating in the dark.
He didn't see a body? No.
The candles then mysteriously disappeared and he decided whoever's by the canal is probably going to come back, so he Legged it with the phone.
Which, when he got home, realised was crap, so didn't try and sell it or even turn it off.
Yeah.
OK.
Oh, yeah - I got the DNA results back from Pujari's house, the apartments where Kalan was staying.
Any evidence of those drugs that I cannot pronounce? No.
I guess that was to be expected.
Perhaps.
But there's one thing I didn't expect to find.
Oh, yeah? There was no evidence of Kalan Dhana's DNA anywhere in that room.
But that's where he lived.
That's where we were TOLD he lived.
Where's Jenna? She's on her way.
You and I both know that the variant is still years away from being ready for market.
We were told to take as long as it took.
This is important work.
But there's another use for it, that Mr Pujari would like to explorethat's not strictly legal.
What other use? And the money he earns from that will be poured back into our trials.
Kalan's death has put us months behind.
Does Jenna know all this? The less people who know, the better.
Did Kalan know? Of course he did - he wrote it all down here.
See for yourself.
See for yourself.
Details of the trial.
Expected outcomes.
Richard? I'm sorry, Jacob.
Hi.
Hi.
It was lovely to see you last night.
I've missed you.
You want to have a look at this.
I thought when I got your message this morning I'm sorry, Amanda, this is urgent.
Either there's been some sort of mistake or the heart's been swapped somehow.
I can assure you, Thomas, the heart wasn't swapped at Chesham.
And I can assure you, Amanda, it wasn't swapped at The Lyell.
Earlier this year we had an attempted break-in.
I told you about it.
Yes.
Yes, well, as a result, we had extra security cameras placed in almost every department.
So, if something like this had happened, it would have been seen.
So, you've checked the tapes? Yeah? Are you serious? Well, look, I know it wasn't us.
How unusual! Dr Thomas Chamberlain trying to shift the blame.
I'm not trying to shift anything.
If The Lyell is at fault, I'll be the first to take full responsibility.
Yeah.
Because you're so bloody good at that, aren't you? Amanda, we have to keep our personal relationship Of course we must.
Must be professional.
Above all else.
CLASSICAL MUSIC PLAYS THROUGH HEADPHONES VOLUME INCREASES MUSIC STOPS, PHONE BEEPS Jenna, have you heard from him? No.
What about you? Nothing.
I've sent at least ten messages.
I'm getting really worried.
Have you got any more texts from Jacob? No, no.
Why the hell didn't he talk to me? He's too angry.
So it's my fault? He's angry with you and upset about what happened to Kalan.
He felt betrayed.
I know.
I wanted to tell the truth, but Pujari wouldn't let me.
I really hope nothing bad has happened.
Have you spoken to Mr Pujari? No.
No.
If you hear anything, or Jacob texts you again, you call me immediately, yes? Yes.
Of course.
I love you, Jenna.
OK.
LINE CUTS OFF MUSIC RESUMES Hiya.
I'm sorry I doubted you.
This shouldn't be about me.
You looked at the evidence and you believed what you saw.
You were right, though, I did feel undermined.
Yeah.
Have you spoken to Amanda Long? Yeah, yeah.
She should be here.
Professor Long, what exactly do you put this error down to? Well, we have both looked at our procedures, the keeping and logging of evidence.
Might it have just been an accident of some kind? In my opinion, the most credible explanation is sabotage.
A heart belonging to one body was swapped with the heart belonging to another, with the purpose of sabotaging the evidence and the subsequent trial.
That is a very serious accusation.
Do you have any idea who would want to do this? My findings were categoric.
PC Francis had an undetected heart condition.
After the hearts were swapped, Professor Long found that the heart was healthy.
Clearly that would have an effect on the outcome of the trial.
Are you suggesting the police had a hand in this? I have no idea.
There are a number of people who would have had access.
Including us.
Do you agree that this was a deliberate act? An act of sabotage, as Dr Alexander has put it? I do.
Yes.
Well, it would seem that way.
Yes.
This is a very serious matter.
We obviously can't continue with this trial.
Yes, my lord.
When the jury return, we will be formally asking you to discharge them.
My lord, we will want to address you on that.
Yes, I can see that you might.
This fiasco must be investigated thoroughly at the highest level.
I will make that clear in court and write in person to the coroner.
The evidence from PC Steven Francis's body will need to be located, and two new postmortems carried out by pathologists from establishments other than Chesham or The Lyell.
I feel I owe you an apology, but I don't expect you to.
Why would You know I hold you in high regard, Nikki.
The feeling's mutual.
I was wrong to say what I did after you gave evidence.
I handled that situation poorly.
I'm sorry.
I'm not used to people feeling sorry for me, not professionally anyway.
I imagine you feel the same.
So, the trial of two men accused of murdering a police officer has been abandoned on our watch.
We'd better get back.
A retrial, can you believe it? At least Dr Alexander has been exonerated.
Has she? We have CCTV footage of those two men punching and kicking the life out of PC Francis.
Both have a history of causing GBH and ABH, and both have admitted violent assault.
We had all that evidence, but we still can't get a conviction.
Have you, by any chance, got to have a look at the DNA samples from the Pujari apartments? Tell me again, Jack, what you found exactly? Nothing.
But isn't that, in itself, suspicious, ma'am? It might be suspicious.
But, then again, it might just be some kind of mistake.
They're running the samples again to make sure, but This whole thing has been staged.
The clothing, the finding of the lanyard, the way they spoke to me.
Even Arthur Pujari going on about some old tree.
Right, look.
It's suspicious.
But without concrete, verifiable forensics - no offence, Jack - it's still not a murder inquiry.
Yep.
Kalan Dhana may have taken those drugs of his own free will, taken out a canoe and fallen asleep with a couple of candles on his stomach.
Best get back to work, eh? So, we need more.
When have we ever needed less? If anyone's set this thing up, it's Arthur Pujari.
What more can we find to convince Briggs? Look .
.
I really appreciate what you've done on this.
It's not over till it's over.
I'll go back and see Arthur Pujari and talk to some of those colleagues of Kalan's again.
What if we go back to where Kalan and Jacob were living, and you test every room? All the rooms looked spotless to me, like they were laboratories themselves.
If they were responsible, how did they get the body in the canal? None of them owned a car, Clarissa checked.
Did they borrow one? Hire one? Use one of Arthur Pujari's? I know Clarissa was looking into it, but she's been somewhat sidetracked.
We all have.
Events.
Yeah.
Events.
Another one? No, thanks.
I'd better get back.
See you.
That's when Steven Francis came in.
The signatures of the funeral director, Greg signed it in, and I countersigned it when it came upstairs.
The bar codes zapped and logged.
You can see the entry times.
This is all when - Friday the 11th, yeah? Nikki did the PM on the Monday.
She removed the heart and took samples from it.
Yes.
I can see that.
The samples were sent off by Alice and, once Nikki had finished, the body was sewn up and returned to the fridge.
OK.
So, the heart is put into a container of formalin by Nikki.
Who, then, put that container into the fridge? According to the log .
.
it was Greg.
Then how long before the heart and the body are moved on to Chesham? They were with us for 11 days before being sent for the second PM.
HE SIGHS 11 days.
So, certainly enough time for Francis's heart to be switched with a healthy one.
Yes.
HE SIGHS You want a tea or something? Nothing, thanks.
It's going well, then.
Just an iceberg, Captain.
Nothing to worry about.
Tell me more about Arthur Pujari.
I thought you knew all about him.
So did I, until I started looking into what the drugs found in Kalan's body might be used for.
Like what? One's a dissociative anaesthetic, the other's a muscle relaxant.
In combination, they're potentially extremely dangerous.
I thought they were developing a non-addictive painkiller.
Ketamine, it's fast-acting, it's non-addictive, but the vecuronium bromide? The ketamine just makes it stronger.
Kalan's hearing aids were paid for by a shell company in the Cayman Islands.
Owned by Pujari? That's the beauty of shell companies.
They tend not to tell you who actually owns them, runs them or takes profits from them.
Or who's trying to hide their tax liabilities.
Particularly from "man of the people" Arthur Pujari.
Mm.
Who openly attacks big companies for not paying their dues.
This shell company has a series of subsidiaries in America.
Texas, Florida, Alabama.
What do you think that means? I'm not sure.
Yet.
Jack, we've found another body.
Who is it? Jacob Nduka.
Shit.
You make a judgment call and sometimes Ready to bring him down? Is that a suicide note? Even if it is a suicide note, that doesn't mean that it's a suicide.
I know that, Detective Constable.
When we get him back to The Lyell, we'll be able to examine You're still open for business, then? I heard DCI Dermot Flanagan was heading your way.
Nothing's been confirmed, as far as I know.
Well, when Flanagan does get there, you'll soon know about it.
It's a confession.
To what? "Kalan and I were working secretly on drug trials.
"We wanted to speed up the process and get ahead of the competition" HE CONTINUES: .
.
so we tested the drugs on ourselves.
One night, Kalan died after I injected him with a new drug.
I'm so ashamed.
I am so sorry to my family for disgracing them in this way.
I know I'm going to hell, and that's only right.
I'm so sorry.
Apparent venepuncture marks on his right .
.
yes, and left anticubital fossae.
Petechial haemorrhaging in and around the eyes.
Cyanosis on the lips.
Both consistent with asphyxial death.
As is this ligature mark around his neck .
.
rising posteriorly.
No fingermarks or other obvious signs of trauma here.
These are his X-rays, yeah? The upper cervical vertebrae seem intact.
Alice, have you got the photos taken at the scene? Yes.
Thank you.
Given the height of the drop, if he'd jumped or been pushed .
.
I'd expect his neck to have been broken.
And here's an interesting thing.
In a hanging death, you get lividity in the feet, the fingertips, the ear lobes.
The blood pooling in the lowest areas possible after death.
There's some here .
.
but nowhere near as much as I'd expect.
Right, let's open him up.
Plume of froth, similar to Kalan - another acute pulmonary oedema? Kalan was dead before he entered the canal.
I believe this man died before he was hanged.
We need tox screening as soon as possible.
Thomas? It's the coroner.
He said it was urgent.
On my way.
If it's not at Chesham, then it has to be someone here.
How do you know it's not someone at Chesham? I saw Amanda last night.
She told me.
Are you two? Thomas! Nikki, this is not the time.
Why didn't you tell me, at least give me a heads-up? It has nothing to do with the case.
I believed you, you know that.
And I believed her because the evidence told me to.
PHONE VIBRATES I'm sorry.
I should have let you know.
I'll leave you to it.
PHONE CONTINUES VIBRATING Amanda? I've made a decision.
Or rather our lawyers have made a decision.
Right? I am talking about work, not us.
Oh.
I've been advised that we should get an independent investigator.
Yes, yes, I've already spoken to the coroner.
It's a criminal investigation now - perverting the course of justice.
He's appointed a senior police officer not connected to the PC Francis case.
Right.
Well, I await the call.
I .
.
wonder, what would you do if I said I was leaving Robert to be with you? Um I thought as much.
It strikes me as one of the great chemical ironies, that a drug used in life-saving surgery is so prevalent in the medical profession as a means of suicide.
Vecuronium bromide.
You think Jacob and Kalan killed themselves? No, no.
I don't.
Jacob clearly didn't hang himself.
From the start, that's what we were meant to think, but .
.
here, look - the tox report.
What about it? Along with a tranquiliser, Jacob had ketamine and vecuronium in his body, but the dosages weren't enough to kill him.
The noose he hung from didn't kill him.
So, what did? There may be another drug.
A drug we're not meant to find.
OK.
Let's extend the screening.
Test the brain tissue for metabolites.
Thomas, what were these brilliant young men doing putting all this shit into their bodies? Visit Pujari, ask him.
Right, I'll see what Vail and I can find at Jacob and Kalan's place.
Now, who lives in a house like this? Hm.
Are you going to behave yourself? What do YOU think? Clarissa Mullery.
Mr Pujari.
Please, come with me.
So, Miss Mullery, to what do I owe this pleasure? Jacob and Kalan were secretly working on a new drug.
According to Jacob's suicide note.
It happens.
Some people like to stay ahead of the game.
But what game were they trying to stay ahead of? I thought Kalan was working on a non-addictive painkiller? That's all the information I have, I'm afraid.
Do you condone what they were doing? Running trials without protocols, without safety standards, on your premises? As Miss World says, all I want is world peace and global access to free health care.
Please, try the cake.
Cook baked it this morning.
Two of your researchers have been found dead.
Both had a ketamine variant in their bodies.
Both had vecuronium bromide swimming around as well.
But do you know what else we found in Jacob's body? Evidence of succinylcholine.
It's normally untraceable, but we found it.
We were meant to think it was suicide.
But it wasn't.
Jacob died a very painful death, Mr Pujari.
That's truly shocking.
Poor boy.
Jack? In here.
They've asked us to leave, come back with a search warrant.
I thought we'd permission to be here.
We did, but now it's been withdrawn.
That wouldn't stop the likes of you now, would it, PC Vail? Listen, I think this is where the experiments may have happened.
How do you know? A bed of some kind was here, in the middle.
See? Swab this stain, see what we get.
Won't take long.
Yes.
I'm sorry about that.
The company lawyers are telling me that I have to ask you to leave.
The same lawyers that helped you set up a shell company in the Caymans that paid over ã100,000 for Kalan's implants? A company with subsidiaries in Georgia, Florida, Texas Ms Mullery Why would you want to mask your operations in the southern states of America? Cos you were planning to sell the drug to American prisons for use on prisoners facing execution.
DOOR OPENS That's quite a leap for a scientist.
But, before you start making insinuations against me and my company, perhaps you should have some proof? Two men died in order to get your drug to market.
A drug used to inject condemned prisoners so they won't move as they're being executed, and not for the prisoners' sake but for those who have to watch.
A drug that is illegal to export from the UK.
What a great mind.
Maybe you should come work for me one day.
Just explain this.
The presence of formaldehyde in Kalan's body.
An embalming drug.
I know what's going on at The Lyell and we both know, in court, this would be considered a mistake at best.
Inadmissible .
.
at worse.
It must be so frustrating to know you're right, but that no-one believes you.
Binni! Could you make sure Ms Mullery finds her way to the front door.
Thank you.
Hello.
Please tell me you found something.
But of course.
A stain, sent off for analysis, and evidence of a bed in the middle of the living room.
That's probably where they ran the experiments.
Probably.
These young people were testing the new drug on themselves.
Did Arthur Pujari confirm that? He did more than that - he dared me to prove it.
He DARED you? Yeah.
Wow, are you still a fan? Is that Kalan's phone? Yes.
He was using a storage app to hold a shedload of data.
From these drug trials? I'm still trying to access it.
Do not suggest I call Max.
Wouldn't dream of it.
I've already tried him.
Now, this is interesting.
So, Kalan's login to the app has been blocked.
And his files deleted.
But if I can partly restore this .
.
we can rebuild him.
We have the technology.
Details from the testing programme.
Dates.
Times.
The ketamine variant, the placebo At least four participants were involved in each of the tests, as administrator, observer or guinea pig.
And I bet we can guess which four.
They've been working on these trials for over two years.
Long time.
Pujari must have known about this.
How else were they being funded? And who was all this data for, if not for him? Hm.
That's not going to prove who killed Jacob, though, is it? No.
No, but there are more files here that might.
KNOCK ON DOOR Yeah? Hi.
Sorry, I just brought you some coffee.
Oh, thanks.
Thomas said you were preparing for a trial.
Yeah, it's a murder conviction that's up before the Court of Appeal.
Nikki, I was just wondering Yeah? It's just I've learned so much from watching yourself and Thomas in the mortuary, but going to court would scare the life out of me.
You just have to know what you're saying, and what you're saying is clear and is true to the best of your knowledge.
Thanks.
And this is the case? Yes.
It's another failure in disclosure.
The victim's GP has recently revealed that the deceased had early-stage multiple sclerosis.
Would that have changed the verdict? In my view, no.
Mrs Coulter was beaten .
.
and stamped on by her husband, and he threw her down the stairs, making it look like an accident.
And he was found guilty? He was.
18 years, I think he got.
Because of your testimony? Maybe.
But who knows what the jury think? What they weren't told was that he'd attacked her previously.
He put her in hospital with a broken jaw, but it was deemed inadmissible at the time, because the judge thought it was unduly prejudicial.
And now you have to do this all over again.
You must get so nervous.
It's like anything, really.
The more you do it, the better you get.
But all those people watching you? All those expectations? It's not just that.
There are some barristers who How shall I put it? .
.
aren't interested in what happened, or in the human beings involved.
They aren't interested in trying to establish the facts.
They spend their entire time trying to get me to fit my evidence to their narrative of what may have happened.
"You say the world is round, Dr Alexander, "but isn't that just your opinion?" The pattern of neuropathology shows what's called coup type injuries.
Yes, to the back of Mrs Coulter's head.
This is caused when a moving object strikes the head.
Isn't that their job, though - to question you, question what you say? Of course.
To question the science and the interpretation of that science.
As with this case - falls and injuries like these are always open to interpretation.
And when there are no witnesses or CCTV, it can be almost impossible to prove what happened with 100% certainty.
But you're certain? Sorry, I'm just trying to help.
I was as certain as I could be at the original trial, and looking at these .
.
and going through my report, I'm even more certain now.
Can I refer you to exhibit 5? I'll draw you what I'm going to say in court, if you like.
You can see if it's clear.
In a fall onto the back of the head, we see contrecoup injury to the opposite side of the brain.
The key is to be as clear as possible for the judges to understand what is quite technical Here's a skull.
Obviously they'll be better diagrams for the court, but this will give you an idea.
A coup injury occurs .
.
under the site of impact with an object.
And a contrecoup injury occurs .
.
on the opposite side of the area that was hit.
As the court will know, a coup injury occurs under the site of impact with an object.
A contrecoup injury occurs on the side opposite the area that was hit.
Coup and contrecoup injuries are cerebral contusions - bruising to the brain.
They can occur individually or together.
When a moving object impacts the stationary head, coup injuries are typical, while contrecoup injuries are produced when the moving head strikes a stationary object.
Now, this evidence can be open to interpretation but, in the end, the head injuries form only a part of what happened.
The left shoulder blade - this was fractured in several places, which is just not typical of a simple fall down the stairs.
What do you mean? Well, if it didn't happen when Mrs Coulter went down the stairs, then it must have happened either before or after - suggesting that she had been assaulted.
How can you be sure? The way the shoulder's fractured and the way the bruising appears and, as I say, she had been stamped on before.
Uh, Nikki, um, have you got a moment? Sure.
Shall I print this out for you? Uh, yeah, that would be great.
Thanks.
These are results from samples that we sent off two days ago.
What? There.
Jacob Nduka's sample has DNA from PC Steven Francis? Yeah.
This is out of control.
Fractures to the right shoulder were found in both X-rays and dissection of the back.
There was extensive haemorrhage in the soft tissues.
The RIGHT shoulder? In the original trial and in these photos, it's clearly the left shoulder.
Sorry, I meant the left.
It's the severity of the fractures that makes these injuries notable.
The first fracture to the head, Doctor, you said it occurred at the back.
Yes.
Again, at the original trial, you said it was to the right side.
Yes.
Yes.
Yes? Yes what? You were wrong then but you're right now, or you're wrong now and were right then? Or, as I suggest, Dr Alexander, you were wrong then AND are wrong now? Mrs Coulter was hit on the side of the head - it was a hard blow And not the back? You're sure? Yes.
Would you like a glass of water to compose yourself, Dr Alexander? No, I'm fine, I just.
.
My lord, the court may be aware there is an ongoing investigation as to whether Lyell was culpable in the collapse of a previous trial.
Part of that investigation is considering whether Dr Alexander has acted inappropriately.
And I might say, my lord, the allegations against Dr Alexander are very serious.
In the light of that, we submit that this matter should be adjourned, pending the outcome of that investigation, which can, if appropriate, be presented to this court as fresh evidence.
Thank you, Mr Delaney.
In the circumstances, we see that as a sensible way forward.
Oh, my God, they were all there.
Do you agree this was a deliberate act? An act of sabotage? I do.
Yes.
You have just said as much in open court.
You were wrong.
Sorry, I'm just trying to help.
But YOU'RE certain? Yes? Yes what? You were wrong then but you're right now? Or you were wrong now and were right then? And he was found guilty because of your testimony.
Shall I print this out for you? Hi, Dad.
According to Mr Delaney, I'm as good as out.
At the very worst, I'll get a retrial.
I don't know what you did, Alice, but you did it.
When I was at uni and Mum broke her jaw .
.
she said she did it, falling over.
Yeah.
As she got out of the car.
I saw the photos.
What photos? What are you talking about? You could see the sole of a boot imprinted on her cheek.
Your boot.
That's not what happened - those photos are fake.
Faked? You think it's as easy as that? Isn't it? You stamped on Mum's jaw! If that was the truth, I'd have been arrested.
Mum dropped the charges.
If you think that's the truth, what are you doing here, Alice? Why have you been helping me? Cos I believed you! Cos you're my dad! Because I loved you! I know what you did and I know what I have to do.
Alice rewrote my report.
Why? Why would she do that? Not only that - her maiden name is Coulter.
And her father is Oh! Gavin Coulter.
Yeah.
I've contacted the police.
She went to see her father in prison, but she's not there, and she's not at her digs.
Maybe this explains the contaminated samples.
I'll let DSI Flanagan know.
We need to find her.
Now it's beginning to make sense.
Nikki? Alice! Please let me explain.
Your father lied to you, and you believed him.
He was my dad.
And with my mum's MS, I couldn't think he was anything but innocent.
He said whenever you stood up in court, everyone believed you, so I had to come up with a way to discredit you.
So you cheated your way into The Lyell to get close to us, to me? Your father's appeal will be rejected.
Good.
He lied to me, he's completely betrayed me.
And what exactly did you do, Alice? You haven't thought about anyone else who's lost someone they loved, what this work means to them, to us! Have you any idea of the number of cases that could be overturned? Well, that wasn't my intention.
Contaminating Kalan's sample with formaldehyde My dad's appeal was coming up .
.
has meant the truth about the deaths of two young men I kept some of the samples clean! Any evidence against the lead suspect will be inadmissible because of the contamination.
The original samples are in storage.
Surely you could use those now.
Arthur Pujari is no longer in the country, Alice.
What about the heart belonging to Steven Francis? I can tell you where it is.
You saw the evidence concerning your own mother's murder.
I know.
And yet you still went through with it.
I had I had to hear it for myself.
From him.
As soon as he started talking, I knew You need to call the police, Alice.
They'll arrest me.
You need to call the police.
And if you don't, I will.
This could be the lipstick found on Kalan and Jacob.
Well, according to Jenna, she and Jacob gave Kalan the sendoff into the canal.
But she's denying any involvement in Jacob's death.
Right.
What about Arthur Pujari? Richard's not talking.
But according to Jenna, Pujari wasn't directly involved.
Not in the drug trials or the disposing of Kalan's body.
Hm.
Nothing is what it seems.
Shall we? Yes, please.
Dr Alexander, what are the consequences of the defendant's actions on your work? What's the point of experts if nobody trusts them? What's the point of evidence if it can so easily be contaminated? The whole integrity of what we strive to achieve could have been catastrophically undermined.
What my colleagues and I seek to do is to understand the cause and manner of a person's death.
But we don't only deal with the dead.
We deal with the living - the families, the judiciary, the coroner, police, the public, the press.
And they all have to trust us.
And if there is a betrayal of that trust .
.
there is a crime.
The opposite of truth is not just a lie.
The opposite of truth is chaos .
.
a chaos that is in danger of bringing down the institutions we depend on to deliver justice.
Thank you, Dr Alexander.
You know me.
Kalan Dhana.
Pujari Pharmaceuticals.
Was it my fault? I gave him the drugs.
BEEPING Shh! Hey.
Mr Pujari? Vail or Hodgson? Would you mind if we had a look around? Can I stop you? Would you want to? Young PC Steven Francis died as a result of the vicious assault he sustained at the hands of the two defendants.
You made a mistake.
I didn't make a mistake.
You have just said as much in open court.
You were wrong.
The Lyell's in all sorts of trouble.
This is the body of Steven Francis.
Caucasian male.
You better bring me the heart.
You didn't find anything.
No.
No, we didn't.
We're ready for the next stage.
One more trial.
Just to be sure.
Is this what killed Kalan? Tell me, or I go to the police.
See this? This is the body of PC Steven Francis, and this is the heart belonging to PC Steven Francis.
I did not make a mistake.
# Testator silens # Costestes e spiritu # Silentium Testator silens.
Can you pay them? I hate that bit.
I always feel I have to come back in the morning and pretend I've stayed the night.
I can't stand the humiliation of them knowing exactly what we've been up to which they probably know.
I'm just talking, waffling.
You are telling me the truth, aren't you, Amanda? About what? My marriage? Us? No, no, I don't mean about that.
The postmortem on PC Francis.
Thomas, do you think I'd meet up with you so you'd cover up No, no Is Nikki really so perfect that she can't make a mistake? One mistake? I'm sorry.
I should never What? Asked me that question or suggested we meet? This isn't about sex or .
.
the thrill of escaping this bloody job for an afternoon or an evening.
This is about love.
We love each other and .
.
that's why it had to end, and that's The problem is, you're the only person in the world I can share any of this with.
I know.
DOOR CLOSES Hello, Leon.
How do you know my name? You out early or are you often down this way? What's it got to do with you? Rumour has it you've got yourself a new phone.
No.
Who said I did? You can't see it, not with the naked eye, but there's a satellite up there and it's pointing down at you, and it's telling me you're using a phone that doesn't belong to you.
Bollocks.
Don't run, Leon.
Please.
I'm too knackered to chase after you.
But, fortunately, they're not.
NIKKI: This is the body of PC Steven Francis.
Evidence number LY-SF-63418 When was this taken? Keep watching.
.
.
This is the heart belonging to PC Steven Francis.
Evidence number LY-SF-63418.
Nikki, what the hell is going on here? I wanted to prove that my original findings were correct.
Who are you with? Who's taking the video? Look, Clarissa's printing out the results.
Results? What results? I took the samples to the laboratory myself.
I don't know what you're talking about, Nikki, but this is a serious breach of every single Nikki did not make a mistake.
Wait.
This has got nothing to do with what happened in court.
She took samples from Steven Francis's heart together with hair from his head.
The two samples have been DNA tested over the weekend, and wait for this.
The heart that you and Professor Long examined doesn't belong to PC Steven Francis.
You're joking.
You and Jack have checked every procedure we do here.
So have Chesham.
Nikki's original PM was with the right heart, but somehow a different heart was sent with the body or was swapped at Chesham.
What about Steven Francis's heart? Where's that now? Morning.
They've found Kalan Dhana's phone.
What did I miss this time? Continuing my interview with Leon Birchwood.
DC Vail, DC Nugent and the duty solicitor, Mrs Alvi, in attendance.
Where were we? What time did you find the phone, Leon? I don't know.
OK.
From the top, what time did you leave work? I told you, just after four.
And it takes you about half an hour to get home? Look, I was just walking that way, down the canal, because you lot took my driver's licence.
We took it, or were you three times over the legal limit when you were stopped and breathalysed? You had no reason to stop me.
Right.
You were walking home between 4am and 4:30am, and there was a blue sports bag left on some cable drums.
And a phone.
The phone wasn't in the bag? No.
It was on some cable drums? Just sitting there? Yeah.
And you didn't search the bag, pull out some clothes, and then find the phone? No.
Did this bag and this phone not belong to someone? Did you not think, "Ooh, that's odd"? Not down there at that time of night! All kinds of shit kicks off.
Look, Leon, I don't give a toss about the phone.
All I'm interested in is who you may have seen by the canal that morning.
You're going to think I was on something.
Other than your son's bike, you mean? OK, Leon says he was here.
It was dark, and he saw a phone and was looking at what else was in the sports bag.
Were the clothes in the bag? So he says.
Leon then heard a noise - some people by the water's edge - and in the water he saw two candles floating in the dark.
He didn't see a body? No.
The candles then mysteriously disappeared and he decided whoever's by the canal is probably going to come back, so he Legged it with the phone.
Which, when he got home, realised was crap, so didn't try and sell it or even turn it off.
Yeah.
OK.
Oh, yeah - I got the DNA results back from Pujari's house, the apartments where Kalan was staying.
Any evidence of those drugs that I cannot pronounce? No.
I guess that was to be expected.
Perhaps.
But there's one thing I didn't expect to find.
Oh, yeah? There was no evidence of Kalan Dhana's DNA anywhere in that room.
But that's where he lived.
That's where we were TOLD he lived.
Where's Jenna? She's on her way.
You and I both know that the variant is still years away from being ready for market.
We were told to take as long as it took.
This is important work.
But there's another use for it, that Mr Pujari would like to explorethat's not strictly legal.
What other use? And the money he earns from that will be poured back into our trials.
Kalan's death has put us months behind.
Does Jenna know all this? The less people who know, the better.
Did Kalan know? Of course he did - he wrote it all down here.
See for yourself.
See for yourself.
Details of the trial.
Expected outcomes.
Richard? I'm sorry, Jacob.
Hi.
Hi.
It was lovely to see you last night.
I've missed you.
You want to have a look at this.
I thought when I got your message this morning I'm sorry, Amanda, this is urgent.
Either there's been some sort of mistake or the heart's been swapped somehow.
I can assure you, Thomas, the heart wasn't swapped at Chesham.
And I can assure you, Amanda, it wasn't swapped at The Lyell.
Earlier this year we had an attempted break-in.
I told you about it.
Yes.
Yes, well, as a result, we had extra security cameras placed in almost every department.
So, if something like this had happened, it would have been seen.
So, you've checked the tapes? Yeah? Are you serious? Well, look, I know it wasn't us.
How unusual! Dr Thomas Chamberlain trying to shift the blame.
I'm not trying to shift anything.
If The Lyell is at fault, I'll be the first to take full responsibility.
Yeah.
Because you're so bloody good at that, aren't you? Amanda, we have to keep our personal relationship Of course we must.
Must be professional.
Above all else.
CLASSICAL MUSIC PLAYS THROUGH HEADPHONES VOLUME INCREASES MUSIC STOPS, PHONE BEEPS Jenna, have you heard from him? No.
What about you? Nothing.
I've sent at least ten messages.
I'm getting really worried.
Have you got any more texts from Jacob? No, no.
Why the hell didn't he talk to me? He's too angry.
So it's my fault? He's angry with you and upset about what happened to Kalan.
He felt betrayed.
I know.
I wanted to tell the truth, but Pujari wouldn't let me.
I really hope nothing bad has happened.
Have you spoken to Mr Pujari? No.
No.
If you hear anything, or Jacob texts you again, you call me immediately, yes? Yes.
Of course.
I love you, Jenna.
OK.
LINE CUTS OFF MUSIC RESUMES Hiya.
I'm sorry I doubted you.
This shouldn't be about me.
You looked at the evidence and you believed what you saw.
You were right, though, I did feel undermined.
Yeah.
Have you spoken to Amanda Long? Yeah, yeah.
She should be here.
Professor Long, what exactly do you put this error down to? Well, we have both looked at our procedures, the keeping and logging of evidence.
Might it have just been an accident of some kind? In my opinion, the most credible explanation is sabotage.
A heart belonging to one body was swapped with the heart belonging to another, with the purpose of sabotaging the evidence and the subsequent trial.
That is a very serious accusation.
Do you have any idea who would want to do this? My findings were categoric.
PC Francis had an undetected heart condition.
After the hearts were swapped, Professor Long found that the heart was healthy.
Clearly that would have an effect on the outcome of the trial.
Are you suggesting the police had a hand in this? I have no idea.
There are a number of people who would have had access.
Including us.
Do you agree that this was a deliberate act? An act of sabotage, as Dr Alexander has put it? I do.
Yes.
Well, it would seem that way.
Yes.
This is a very serious matter.
We obviously can't continue with this trial.
Yes, my lord.
When the jury return, we will be formally asking you to discharge them.
My lord, we will want to address you on that.
Yes, I can see that you might.
This fiasco must be investigated thoroughly at the highest level.
I will make that clear in court and write in person to the coroner.
The evidence from PC Steven Francis's body will need to be located, and two new postmortems carried out by pathologists from establishments other than Chesham or The Lyell.
I feel I owe you an apology, but I don't expect you to.
Why would You know I hold you in high regard, Nikki.
The feeling's mutual.
I was wrong to say what I did after you gave evidence.
I handled that situation poorly.
I'm sorry.
I'm not used to people feeling sorry for me, not professionally anyway.
I imagine you feel the same.
So, the trial of two men accused of murdering a police officer has been abandoned on our watch.
We'd better get back.
A retrial, can you believe it? At least Dr Alexander has been exonerated.
Has she? We have CCTV footage of those two men punching and kicking the life out of PC Francis.
Both have a history of causing GBH and ABH, and both have admitted violent assault.
We had all that evidence, but we still can't get a conviction.
Have you, by any chance, got to have a look at the DNA samples from the Pujari apartments? Tell me again, Jack, what you found exactly? Nothing.
But isn't that, in itself, suspicious, ma'am? It might be suspicious.
But, then again, it might just be some kind of mistake.
They're running the samples again to make sure, but This whole thing has been staged.
The clothing, the finding of the lanyard, the way they spoke to me.
Even Arthur Pujari going on about some old tree.
Right, look.
It's suspicious.
But without concrete, verifiable forensics - no offence, Jack - it's still not a murder inquiry.
Yep.
Kalan Dhana may have taken those drugs of his own free will, taken out a canoe and fallen asleep with a couple of candles on his stomach.
Best get back to work, eh? So, we need more.
When have we ever needed less? If anyone's set this thing up, it's Arthur Pujari.
What more can we find to convince Briggs? Look .
.
I really appreciate what you've done on this.
It's not over till it's over.
I'll go back and see Arthur Pujari and talk to some of those colleagues of Kalan's again.
What if we go back to where Kalan and Jacob were living, and you test every room? All the rooms looked spotless to me, like they were laboratories themselves.
If they were responsible, how did they get the body in the canal? None of them owned a car, Clarissa checked.
Did they borrow one? Hire one? Use one of Arthur Pujari's? I know Clarissa was looking into it, but she's been somewhat sidetracked.
We all have.
Events.
Yeah.
Events.
Another one? No, thanks.
I'd better get back.
See you.
That's when Steven Francis came in.
The signatures of the funeral director, Greg signed it in, and I countersigned it when it came upstairs.
The bar codes zapped and logged.
You can see the entry times.
This is all when - Friday the 11th, yeah? Nikki did the PM on the Monday.
She removed the heart and took samples from it.
Yes.
I can see that.
The samples were sent off by Alice and, once Nikki had finished, the body was sewn up and returned to the fridge.
OK.
So, the heart is put into a container of formalin by Nikki.
Who, then, put that container into the fridge? According to the log .
.
it was Greg.
Then how long before the heart and the body are moved on to Chesham? They were with us for 11 days before being sent for the second PM.
HE SIGHS 11 days.
So, certainly enough time for Francis's heart to be switched with a healthy one.
Yes.
HE SIGHS You want a tea or something? Nothing, thanks.
It's going well, then.
Just an iceberg, Captain.
Nothing to worry about.
Tell me more about Arthur Pujari.
I thought you knew all about him.
So did I, until I started looking into what the drugs found in Kalan's body might be used for.
Like what? One's a dissociative anaesthetic, the other's a muscle relaxant.
In combination, they're potentially extremely dangerous.
I thought they were developing a non-addictive painkiller.
Ketamine, it's fast-acting, it's non-addictive, but the vecuronium bromide? The ketamine just makes it stronger.
Kalan's hearing aids were paid for by a shell company in the Cayman Islands.
Owned by Pujari? That's the beauty of shell companies.
They tend not to tell you who actually owns them, runs them or takes profits from them.
Or who's trying to hide their tax liabilities.
Particularly from "man of the people" Arthur Pujari.
Mm.
Who openly attacks big companies for not paying their dues.
This shell company has a series of subsidiaries in America.
Texas, Florida, Alabama.
What do you think that means? I'm not sure.
Yet.
Jack, we've found another body.
Who is it? Jacob Nduka.
Shit.
You make a judgment call and sometimes Ready to bring him down? Is that a suicide note? Even if it is a suicide note, that doesn't mean that it's a suicide.
I know that, Detective Constable.
When we get him back to The Lyell, we'll be able to examine You're still open for business, then? I heard DCI Dermot Flanagan was heading your way.
Nothing's been confirmed, as far as I know.
Well, when Flanagan does get there, you'll soon know about it.
It's a confession.
To what? "Kalan and I were working secretly on drug trials.
"We wanted to speed up the process and get ahead of the competition" HE CONTINUES: .
.
so we tested the drugs on ourselves.
One night, Kalan died after I injected him with a new drug.
I'm so ashamed.
I am so sorry to my family for disgracing them in this way.
I know I'm going to hell, and that's only right.
I'm so sorry.
Apparent venepuncture marks on his right .
.
yes, and left anticubital fossae.
Petechial haemorrhaging in and around the eyes.
Cyanosis on the lips.
Both consistent with asphyxial death.
As is this ligature mark around his neck .
.
rising posteriorly.
No fingermarks or other obvious signs of trauma here.
These are his X-rays, yeah? The upper cervical vertebrae seem intact.
Alice, have you got the photos taken at the scene? Yes.
Thank you.
Given the height of the drop, if he'd jumped or been pushed .
.
I'd expect his neck to have been broken.
And here's an interesting thing.
In a hanging death, you get lividity in the feet, the fingertips, the ear lobes.
The blood pooling in the lowest areas possible after death.
There's some here .
.
but nowhere near as much as I'd expect.
Right, let's open him up.
Plume of froth, similar to Kalan - another acute pulmonary oedema? Kalan was dead before he entered the canal.
I believe this man died before he was hanged.
We need tox screening as soon as possible.
Thomas? It's the coroner.
He said it was urgent.
On my way.
If it's not at Chesham, then it has to be someone here.
How do you know it's not someone at Chesham? I saw Amanda last night.
She told me.
Are you two? Thomas! Nikki, this is not the time.
Why didn't you tell me, at least give me a heads-up? It has nothing to do with the case.
I believed you, you know that.
And I believed her because the evidence told me to.
PHONE VIBRATES I'm sorry.
I should have let you know.
I'll leave you to it.
PHONE CONTINUES VIBRATING Amanda? I've made a decision.
Or rather our lawyers have made a decision.
Right? I am talking about work, not us.
Oh.
I've been advised that we should get an independent investigator.
Yes, yes, I've already spoken to the coroner.
It's a criminal investigation now - perverting the course of justice.
He's appointed a senior police officer not connected to the PC Francis case.
Right.
Well, I await the call.
I .
.
wonder, what would you do if I said I was leaving Robert to be with you? Um I thought as much.
It strikes me as one of the great chemical ironies, that a drug used in life-saving surgery is so prevalent in the medical profession as a means of suicide.
Vecuronium bromide.
You think Jacob and Kalan killed themselves? No, no.
I don't.
Jacob clearly didn't hang himself.
From the start, that's what we were meant to think, but .
.
here, look - the tox report.
What about it? Along with a tranquiliser, Jacob had ketamine and vecuronium in his body, but the dosages weren't enough to kill him.
The noose he hung from didn't kill him.
So, what did? There may be another drug.
A drug we're not meant to find.
OK.
Let's extend the screening.
Test the brain tissue for metabolites.
Thomas, what were these brilliant young men doing putting all this shit into their bodies? Visit Pujari, ask him.
Right, I'll see what Vail and I can find at Jacob and Kalan's place.
Now, who lives in a house like this? Hm.
Are you going to behave yourself? What do YOU think? Clarissa Mullery.
Mr Pujari.
Please, come with me.
So, Miss Mullery, to what do I owe this pleasure? Jacob and Kalan were secretly working on a new drug.
According to Jacob's suicide note.
It happens.
Some people like to stay ahead of the game.
But what game were they trying to stay ahead of? I thought Kalan was working on a non-addictive painkiller? That's all the information I have, I'm afraid.
Do you condone what they were doing? Running trials without protocols, without safety standards, on your premises? As Miss World says, all I want is world peace and global access to free health care.
Please, try the cake.
Cook baked it this morning.
Two of your researchers have been found dead.
Both had a ketamine variant in their bodies.
Both had vecuronium bromide swimming around as well.
But do you know what else we found in Jacob's body? Evidence of succinylcholine.
It's normally untraceable, but we found it.
We were meant to think it was suicide.
But it wasn't.
Jacob died a very painful death, Mr Pujari.
That's truly shocking.
Poor boy.
Jack? In here.
They've asked us to leave, come back with a search warrant.
I thought we'd permission to be here.
We did, but now it's been withdrawn.
That wouldn't stop the likes of you now, would it, PC Vail? Listen, I think this is where the experiments may have happened.
How do you know? A bed of some kind was here, in the middle.
See? Swab this stain, see what we get.
Won't take long.
Yes.
I'm sorry about that.
The company lawyers are telling me that I have to ask you to leave.
The same lawyers that helped you set up a shell company in the Caymans that paid over ã100,000 for Kalan's implants? A company with subsidiaries in Georgia, Florida, Texas Ms Mullery Why would you want to mask your operations in the southern states of America? Cos you were planning to sell the drug to American prisons for use on prisoners facing execution.
DOOR OPENS That's quite a leap for a scientist.
But, before you start making insinuations against me and my company, perhaps you should have some proof? Two men died in order to get your drug to market.
A drug used to inject condemned prisoners so they won't move as they're being executed, and not for the prisoners' sake but for those who have to watch.
A drug that is illegal to export from the UK.
What a great mind.
Maybe you should come work for me one day.
Just explain this.
The presence of formaldehyde in Kalan's body.
An embalming drug.
I know what's going on at The Lyell and we both know, in court, this would be considered a mistake at best.
Inadmissible .
.
at worse.
It must be so frustrating to know you're right, but that no-one believes you.
Binni! Could you make sure Ms Mullery finds her way to the front door.
Thank you.
Hello.
Please tell me you found something.
But of course.
A stain, sent off for analysis, and evidence of a bed in the middle of the living room.
That's probably where they ran the experiments.
Probably.
These young people were testing the new drug on themselves.
Did Arthur Pujari confirm that? He did more than that - he dared me to prove it.
He DARED you? Yeah.
Wow, are you still a fan? Is that Kalan's phone? Yes.
He was using a storage app to hold a shedload of data.
From these drug trials? I'm still trying to access it.
Do not suggest I call Max.
Wouldn't dream of it.
I've already tried him.
Now, this is interesting.
So, Kalan's login to the app has been blocked.
And his files deleted.
But if I can partly restore this .
.
we can rebuild him.
We have the technology.
Details from the testing programme.
Dates.
Times.
The ketamine variant, the placebo At least four participants were involved in each of the tests, as administrator, observer or guinea pig.
And I bet we can guess which four.
They've been working on these trials for over two years.
Long time.
Pujari must have known about this.
How else were they being funded? And who was all this data for, if not for him? Hm.
That's not going to prove who killed Jacob, though, is it? No.
No, but there are more files here that might.
KNOCK ON DOOR Yeah? Hi.
Sorry, I just brought you some coffee.
Oh, thanks.
Thomas said you were preparing for a trial.
Yeah, it's a murder conviction that's up before the Court of Appeal.
Nikki, I was just wondering Yeah? It's just I've learned so much from watching yourself and Thomas in the mortuary, but going to court would scare the life out of me.
You just have to know what you're saying, and what you're saying is clear and is true to the best of your knowledge.
Thanks.
And this is the case? Yes.
It's another failure in disclosure.
The victim's GP has recently revealed that the deceased had early-stage multiple sclerosis.
Would that have changed the verdict? In my view, no.
Mrs Coulter was beaten .
.
and stamped on by her husband, and he threw her down the stairs, making it look like an accident.
And he was found guilty? He was.
18 years, I think he got.
Because of your testimony? Maybe.
But who knows what the jury think? What they weren't told was that he'd attacked her previously.
He put her in hospital with a broken jaw, but it was deemed inadmissible at the time, because the judge thought it was unduly prejudicial.
And now you have to do this all over again.
You must get so nervous.
It's like anything, really.
The more you do it, the better you get.
But all those people watching you? All those expectations? It's not just that.
There are some barristers who How shall I put it? .
.
aren't interested in what happened, or in the human beings involved.
They aren't interested in trying to establish the facts.
They spend their entire time trying to get me to fit my evidence to their narrative of what may have happened.
"You say the world is round, Dr Alexander, "but isn't that just your opinion?" The pattern of neuropathology shows what's called coup type injuries.
Yes, to the back of Mrs Coulter's head.
This is caused when a moving object strikes the head.
Isn't that their job, though - to question you, question what you say? Of course.
To question the science and the interpretation of that science.
As with this case - falls and injuries like these are always open to interpretation.
And when there are no witnesses or CCTV, it can be almost impossible to prove what happened with 100% certainty.
But you're certain? Sorry, I'm just trying to help.
I was as certain as I could be at the original trial, and looking at these .
.
and going through my report, I'm even more certain now.
Can I refer you to exhibit 5? I'll draw you what I'm going to say in court, if you like.
You can see if it's clear.
In a fall onto the back of the head, we see contrecoup injury to the opposite side of the brain.
The key is to be as clear as possible for the judges to understand what is quite technical Here's a skull.
Obviously they'll be better diagrams for the court, but this will give you an idea.
A coup injury occurs .
.
under the site of impact with an object.
And a contrecoup injury occurs .
.
on the opposite side of the area that was hit.
As the court will know, a coup injury occurs under the site of impact with an object.
A contrecoup injury occurs on the side opposite the area that was hit.
Coup and contrecoup injuries are cerebral contusions - bruising to the brain.
They can occur individually or together.
When a moving object impacts the stationary head, coup injuries are typical, while contrecoup injuries are produced when the moving head strikes a stationary object.
Now, this evidence can be open to interpretation but, in the end, the head injuries form only a part of what happened.
The left shoulder blade - this was fractured in several places, which is just not typical of a simple fall down the stairs.
What do you mean? Well, if it didn't happen when Mrs Coulter went down the stairs, then it must have happened either before or after - suggesting that she had been assaulted.
How can you be sure? The way the shoulder's fractured and the way the bruising appears and, as I say, she had been stamped on before.
Uh, Nikki, um, have you got a moment? Sure.
Shall I print this out for you? Uh, yeah, that would be great.
Thanks.
These are results from samples that we sent off two days ago.
What? There.
Jacob Nduka's sample has DNA from PC Steven Francis? Yeah.
This is out of control.
Fractures to the right shoulder were found in both X-rays and dissection of the back.
There was extensive haemorrhage in the soft tissues.
The RIGHT shoulder? In the original trial and in these photos, it's clearly the left shoulder.
Sorry, I meant the left.
It's the severity of the fractures that makes these injuries notable.
The first fracture to the head, Doctor, you said it occurred at the back.
Yes.
Again, at the original trial, you said it was to the right side.
Yes.
Yes.
Yes? Yes what? You were wrong then but you're right now, or you're wrong now and were right then? Or, as I suggest, Dr Alexander, you were wrong then AND are wrong now? Mrs Coulter was hit on the side of the head - it was a hard blow And not the back? You're sure? Yes.
Would you like a glass of water to compose yourself, Dr Alexander? No, I'm fine, I just.
.
My lord, the court may be aware there is an ongoing investigation as to whether Lyell was culpable in the collapse of a previous trial.
Part of that investigation is considering whether Dr Alexander has acted inappropriately.
And I might say, my lord, the allegations against Dr Alexander are very serious.
In the light of that, we submit that this matter should be adjourned, pending the outcome of that investigation, which can, if appropriate, be presented to this court as fresh evidence.
Thank you, Mr Delaney.
In the circumstances, we see that as a sensible way forward.
Oh, my God, they were all there.
Do you agree this was a deliberate act? An act of sabotage? I do.
Yes.
You have just said as much in open court.
You were wrong.
Sorry, I'm just trying to help.
But YOU'RE certain? Yes? Yes what? You were wrong then but you're right now? Or you were wrong now and were right then? And he was found guilty because of your testimony.
Shall I print this out for you? Hi, Dad.
According to Mr Delaney, I'm as good as out.
At the very worst, I'll get a retrial.
I don't know what you did, Alice, but you did it.
When I was at uni and Mum broke her jaw .
.
she said she did it, falling over.
Yeah.
As she got out of the car.
I saw the photos.
What photos? What are you talking about? You could see the sole of a boot imprinted on her cheek.
Your boot.
That's not what happened - those photos are fake.
Faked? You think it's as easy as that? Isn't it? You stamped on Mum's jaw! If that was the truth, I'd have been arrested.
Mum dropped the charges.
If you think that's the truth, what are you doing here, Alice? Why have you been helping me? Cos I believed you! Cos you're my dad! Because I loved you! I know what you did and I know what I have to do.
Alice rewrote my report.
Why? Why would she do that? Not only that - her maiden name is Coulter.
And her father is Oh! Gavin Coulter.
Yeah.
I've contacted the police.
She went to see her father in prison, but she's not there, and she's not at her digs.
Maybe this explains the contaminated samples.
I'll let DSI Flanagan know.
We need to find her.
Now it's beginning to make sense.
Nikki? Alice! Please let me explain.
Your father lied to you, and you believed him.
He was my dad.
And with my mum's MS, I couldn't think he was anything but innocent.
He said whenever you stood up in court, everyone believed you, so I had to come up with a way to discredit you.
So you cheated your way into The Lyell to get close to us, to me? Your father's appeal will be rejected.
Good.
He lied to me, he's completely betrayed me.
And what exactly did you do, Alice? You haven't thought about anyone else who's lost someone they loved, what this work means to them, to us! Have you any idea of the number of cases that could be overturned? Well, that wasn't my intention.
Contaminating Kalan's sample with formaldehyde My dad's appeal was coming up .
.
has meant the truth about the deaths of two young men I kept some of the samples clean! Any evidence against the lead suspect will be inadmissible because of the contamination.
The original samples are in storage.
Surely you could use those now.
Arthur Pujari is no longer in the country, Alice.
What about the heart belonging to Steven Francis? I can tell you where it is.
You saw the evidence concerning your own mother's murder.
I know.
And yet you still went through with it.
I had I had to hear it for myself.
From him.
As soon as he started talking, I knew You need to call the police, Alice.
They'll arrest me.
You need to call the police.
And if you don't, I will.
This could be the lipstick found on Kalan and Jacob.
Well, according to Jenna, she and Jacob gave Kalan the sendoff into the canal.
But she's denying any involvement in Jacob's death.
Right.
What about Arthur Pujari? Richard's not talking.
But according to Jenna, Pujari wasn't directly involved.
Not in the drug trials or the disposing of Kalan's body.
Hm.
Nothing is what it seems.
Shall we? Yes, please.
Dr Alexander, what are the consequences of the defendant's actions on your work? What's the point of experts if nobody trusts them? What's the point of evidence if it can so easily be contaminated? The whole integrity of what we strive to achieve could have been catastrophically undermined.
What my colleagues and I seek to do is to understand the cause and manner of a person's death.
But we don't only deal with the dead.
We deal with the living - the families, the judiciary, the coroner, police, the public, the press.
And they all have to trust us.
And if there is a betrayal of that trust .
.
there is a crime.
The opposite of truth is not just a lie.
The opposite of truth is chaos .
.
a chaos that is in danger of bringing down the institutions we depend on to deliver justice.
Thank you, Dr Alexander.
