He was four years older than Dean.
Found in the street with a fatal knife wound.
No one ever arrested, no witnesses, although the original report suggests the Quinns had a good idea who was to blame.
They closed ranks.
And where did the attack take place?
Ellerfield Road, Colindale, near where they lived at the time.
Why does that ring a bell?
I don't know, it'll come-- anything else?
Uh... just anecdotal stuff from the door-to-doors that Stephen was not like the other brothers, a quiet lad, academic, not a fighter at all, so it was an odd one.
Okay, thank you, good detail.

Then I found one other account listed with his, but not in his name.
Now, that account is in the name of Georgie Graves.
Dean set it up, and he's the signatory, and the account identifier is godson.
Now, Dean makes regular payments of 40 quid a month into that account, but that's literally all the activity there is.

I have news for you guys on your pen.
So I've ran various tests...
SUNNY: So we do now have a witness who can identify you by name as being the young man involved in a fight with Matthew Walsh in the Ifield pub three weeks before he died.
The landlady, Suzie Montgomery.
Mm, well, I'm sorry, but she's wrong, it wasn't me.
Except we have another witness who also says that it was.
And Fiona has given us a lot of detail about what happened between you and Matthew Walsh in the pub, but also a lot of detail about what happened the night of Walsh's death.
Do you have anything that you want to add to what you told us in our last discussion, Ram?
Because this is your opportunity.
What's she told you?
I'd prefer to hear your side of things first.
It was Rob who spotted him.
I was half-asleep.
It was Rob who decided to pull over.
Uh, so you lied before.
It was also Rob who suggested we give him a tug.
And how did Rob know him?
He was in the pub that night.
There's no recollection by anyone else of him being there.
Well, he's a quiet lad.
Tended to fade into the background.
Yeah, quiet and six-foot-five.
Well, he was there, it was him who spotted Walsh, and got out first.
Oh, so you now admit also that you got out of the car?
(inhales sharply) I did, yes.
So you lied about that before, as well.
So did you also run after him, after Matty Walsh?
You walked after the guy who, just a few weeks before, had knocked seven shades out of you.
And then when you found him?
I didn't find him.
How do you mean?
I didn't even find Rob or the others.
After they got out, I didn't find any of them, so I headed home.
But you were in the car when it got pulled over.
(exhales) So, after maybe 15 minutes of looking for the others, I decided to head back to the main road, hope for a night bus.
About half a mile down the road, maybe 40 minutes after I first got out of the car, it pulled up-- Rob behind the wheel.

ALFIE: Send Cass my best.
SUNNY: Six days ago, a phone mast picked up a signal from your phone heading down the A3.
I mention it because we also picked up Dean Barton's phone, um, same day, coming down from Rochester, and about the same time, also heading down the B3256, this very small B-road in Surrey.
He switched his phone off about a mile down that road.
Did you meet him somewhere down there, Ram?
What were you doing down there, then?
I went for a walk to clear my head.
I've got some personal issues going on in my life.
It's a bit of a coincidence, isn't it?
Dean Barton, a bloke that you say that you haven't seen for 30 years, also happens to be down there at the same time.
60 miles from his house, 30 from yours.
But let's agree for now that it was a coincidence.
What isn't one, though, is the ten grand Dean Barton transferred to your ex-wife's bank account just nine days ago.
And we checked with your ex, Grace?
And she had vague recollection of opening an online account with you many years ago, but had absolutely no idea that it still existed.
Nor that from 2001 to 2008, three or four times a year, lump sums of 5,000 pounds were paid into that account from the same account the 10,000 was sent the other day.
An account run by Dean Barton.
We also checked your landline calls a couple of days either side of the recent payment.
Can you tell me, DCI Sidhu, why you called the desk line of an Andy Renfold, a customs officer at the Port of Fenmarsh, the day the money appeared in your account?
You and Dean Barton clearly have an ongoing relationship going back many years involving him giving you money.
With the Fenmarsh customs connection and the Barton family's criminal history, it's not a massive leap to guess that this has got something to do with drug importation and bribery.
Would I be on the right lines?
So I have to ask you, where you, as a serving police officer, might be susceptible to bribery, what might Dean Barton hold over you, DCI Sidhu?
I didn't kill him.
I found him on the ground, bleeding from the head.
(shuddered breathing) Next to a wall.
I tried to save him.
Ask the others, they were there-- I gave him CPR.
I did everything I could to save him.
I'm not a murderer.
(plastic bag shuffling) We found that in your desk.
How long have you used a fountain pen, DCI Sidhu?

RECEPTIONIST: Come on up.
(door buzzing) Thanks.
SUNNY: I'd like to start, Dean, with the night of Matthew Walsh's death, because the account that you gave my colleague now differs significantly from what we've since heard from both Ram Sidhu and Fiona Grayson.
So is there anything that you'd like to change?
Okay, what would you like to change?
So, um, after your colleague left, I went back over that night, had a really good think about it, um, and it was, it was only then that I remembered that actually, I'd slept for most of the journey.
So whilst I said that the car hadn't stopped before it was pulled over by the police, it might well have done, but it's just I would have had no recollection of it.
Okay, well, once again, that doesn't chime with what both Ram Sidhu and Fiona Grayson have told us.
What they're now saying is that when it first stopped, you did in fact get out of the car, you did go after Matthew Walsh, and then later, you did help put the body in the boot of the car.
Yeah, well, whoever said that is misremembering or covering their own back, okay?
If, if somebody stuck a body in the back of the car whilst I was asleep, I mean, it... (stammering): It's possible, I guess.
I knew nothing about it.
So you knew nothing of the events of that night at all.
Tell me, Dean, how on Earth did you manage to convince Ram Sidhu, an intelligent and ambitious young police officer, to become part of your cocaine smuggling operation?
What cocaine smuggling operation?
I am showing the suspect exhibit MB001, a selection of bank statements from an account set up by you, Dean, detailing multiple money transfers between this account and another account linked with Ram Sidhu.
A couple of hours ago, police arrested a customs officer called Andy Renfold.
Been very cooperative already, apparently.
And over the next few weeks, our forensics finance teams will be all over your financial history, and I suspect, given time, will be able to prove that you were importing cocaine through the Port of Fenmarsh.
So again, I ask you, was it just coincidence that your old friend from Hendon was so easily corruptible, or did you have some unique kind of leverage over him?

Unlikely-- he'd been dead eight months by then.
