There's not that many murders where you essentially watch someone die on body

-worn video.

You never get the smoking gun.

It's the theories of little wins.

They thought they wouldn't get caught.

They thought they were invincible.

we know all the tricks i

could be listening to

your calls i could be looking at your text messages i could be watching where

you are right now and you wouldn't know

That mobile phone can incriminate him.

Showing off his knife, he was 13.

There's vast amounts of data coming in.

Everyone's waiting for the analysts to come up with the goods.

You can't afford to waste a minute.

It was just chaos.

And even if you've not been told the truth, a digital footprint can't be

disputed.

I got that phone call late, knowing that the next morning this was going to be

announced as a murder.

Someone had chased down a child.

Stabbed him nearly 20 times.

But there wasn't much more he could say other than his name, Lariko Steed.

And that there were four people that had attacked him.

Lariko, how many people attacked you?

Four?

We call it a dying declaration.

I think the last time he was able to speak was on that video.

So you're essentially watching life head away.

There's a knock at the door.

It's the police.

The first thing they asked me is, where is my son?

That's when they said, he's been stabbed.

Everything ran out of me. I almost felt like I couldn't breathe.

Nothing inside of me believed what he was saying.

Very good. He was my only boy.

Back in Bermuda, people would tell him, you look just like your mama, baby.

Our bond was different.

That was my baby.

On the first day I took over, we basically know there's been a chase.

There's four suspects involved, confirmed by Larico himself.

We didn't know why Larico had been killed and we still didn't really know

where it had happened.

We know where it ended, but where did it start?

We've been stabbed a few times around this place.

About 18 times.

It's a frenzied attack.

The sort of digital experts I want around me at the start of a murder are

telephone experts and intelligence experts.

My first job will be to go to the victim's call data, to go to a specific

time, specific date, the time that the incident occurred, and work backwards

from that.

Normally, you'd have a victim's device on them. That was missing.

We didn't have that.

I go to my specialist digital experts, specialist researchers.

I say, just tell me about any piece of intelligence about Lariko.

Who are his friends? Who is his associate?

What do we know about the tensions in the area at the time?

I went on to all of our police systems, which saw all of the intelligence that

was received.

Massive database.

Hundreds of thousands of pieces of information on any known criminals, gang

-related activity.

Usually, we have an inkling, we have an intelligence picture.

We didn't have any of that for Enrique.

I started to question, why him?

I didn't know anything about him.

It was just really strange that we'd got this young 17-year-old lad and we still

didn't even have a motive.

It was really unusual.

We widened our intelligence strategy, we widened our digital strategy, hopeful

that we'd just get that strand which would point us in the right direction.

The pressure can be phenomenal at times.

You want to do your best.

You know, you want to catch the offenders. You don't want them running

around the city.

It's up and down.

You've had very little sleep.

You know it's on your shoulders to try and keep people safe.

The first real breakthrough was...

At a briefing, through intelligence, we were given a name of someone known to

Lariko.

Let's call her Girl One because she's a child.

A slightly unusual name, lots of different spellings.

We find four people with this particular name on social media.

There was one in particular who stood out for us that...

We think this is the right one.

She's 15.

There are a couple of missing persons, enquiries, but nothing else that's

recorded with us.

Why is a girl of this age involved in something so drastic as this?

We bring her in as a witness to talk to her.

Now, we're going to speak about an incident that happened last week, which

you're aware of, but the most important thing is that you tell the truth about

what's happened. That is really, really important.

I know you're 15 years old, and I'm sure you understand the difference between

right and wrong.

When we spoke to this girl, she actually said, yes, I was with Lyrica on that

night.

For the first time, we've got someone who was with him.

just prior to the murder.

She tells us that

she doesn't know Lyrico that well. They've agreed to meet up for a date

and go for a walk to a park.

What were you two doing other than talking?

She

said

these figures then rob her, take her iPad.

She's terrified. They run off with her iPad.

She doesn't know what to do.

And after that, then, I went to look for Rico, and I couldn't find her, so I went

to see her again, because I'm worried she's dead.

Girl one is very significant, because she's the last person I know that's seen

Rico alive.

She's the only person I know that's seen the offenders.

Now that we know La Rico's been in the park and we've got a whole new area now

that we need to focus on, a whole new area of potential witnesses, CCTV, dash

cam, phone cell sites.

I remember the officer in charge coming through and saying, what do you think to

this?

I see La Rico with a girl chatting.

And then all of a sudden, four figures starburst and chase him, and very

quickly he's on his toes and you see him sprinting.

There was one male running off, and then it looked like there was another group.

There was two at the front chasing after him and two slightly further back.

This is gold dust to us, because one, we know Lariko hasn't started the fight.

who we've got a direction of travel.

Three, we know that it's not a matter of the killer just finding Lyrica on the

street.

So this is the first point where we start to think, well, how did they know?

How did they know he'd be there?

Carrying on, looking at that footage, we track girls leaving the park, walking

casually down.

Hempstead Lane, and then we see her get onto the bus, like she's going about her

everyday business.

We have really clear CCTV of her sat at the back of a bus, and then

you hear the sirens and you see the blue lights of the police going to help

Lariko, and at that point she ducks down behind the seat and hides.

And that's really telling.

Hang on a minute, this date has just run off, being pursued, and you don't want

the police to know you're there. Why not?

And then we'd see her on an iPad that she's told us was stolen during the

incident where Loriko was chased.

So that's a real game-changer, because she's lying.

So after Lurico passed, it was just a blur.

The police are asking me loads of questions, and I had no answers for

them.

I was so close-eyed to everything here in Nottingham

until my son passed.

He always reassured me that when he was out, that he was safe.

I didn't know about the street life in the UK.

I was just thinking about my son.

Thinking about how he felt when he ran. What did it feel like for him when the

knife ran into him?

And when he ran, what sorts of thoughts were in his mind?

I wondered if he prayed.

I feel he did.

We did the post-mortem on Lariko and there were about

18 wounds.

He'd got six knife wounds to his face.

So at that point, you know, he's on his back then, trying to defend himself.

You don't stab somebody that many times and think, hey, he'll be all right.

If you literally just count to 18 at whatever speed, one.

Two, three, four, five.

Observing that a lot. You're not trying to scare someone. You are trying to kill

them.

We decide at this point it's personal.

Could it be retribution?

Could it be gang-related?

I'm about ten days in.

to the murder investigation now, and the pressure's starting to rise.

I have girl one in custody, but still no other suspect.

It's suspected that you've got more knowledge of the offence, and you've not

been forthcoming with the truth.

And it's suspected...

You may have a more significant role in the murder.

If Lurico was being looked for by gangs or people he's fallen out with, how

do they know that he's in a dark park in the middle of a ball on a Tuesday night?

Do you have any reason that you don't want to tell him?

I'm afraid of my safety.

You're afraid of your safety?

Girl one doesn't really know what's happened.

She was scared.

People were masked and it's all just a bit confusing.

And we know girl one has been lying to us about the iPad and hiding from the

police.

So we do go to the Crown Prosecution Service at that stage and

ask. if they will charge her, but there's just not enough evidence to meet

the threshold.

We have to let her go.

In investigations as complicated as homicides are, you do get a lot of red

herrings.

You think you're going down the right route, but ultimately it leads you to

nothing.

I need to know how those four suspects have got to the scene.

Have they gone on a bus or looked at the buses? How did they get there?

We go to all the taxi firms in Nottingham to establish if

they've picked up four youths and dropped them off in the Bulwell area.

Criminals often use local.

rather than Uber, because there's more of a digital footprint with Uber because

it's connected to your card.

Central

cars

come back to us and say they've had two drivers...

who've provided taxes for four youth in the Bulwell area within our time

parameters.

We found out that they were collected and taken back to an area called

Cementon, which is a long way away from Bulwell.

So at this point, I'm getting quite excited.

I'm hoping to get four phones moving together in a cab.

I'm obviously hoping to get forensic evidence.

Is there any blood?

This is a real opportunity.

We see two taxis and we search the taxis

and subject them to full forensic examinations.

By the time we've got those taxis, they've been vomited in by night.

And the taxi driver's obviously cleaned those cabs numerous times.

What we're really hoping for is Lariko's blood in the taxi and it's just not

there.

At the last minute, when we think this taxi hasn't yielded anything,

the taxi driver says to us, oh, but I've got this. And he, with

his bare hands, pulls out a phone.

And says, one of them left this, if this is any good for you.

These lads have got out the car and run off without paying and they've left

their phone in the car.

I've now got a mobile phone that can be interrogated.

Brilliant.

Following the inquiries with the taxi drivers, I'm handed a blue Nokia phone

from the back seat of the taxi, having left the scene of a murder.

It's unbelievable.

It really is unbelievable.

One of the basic things to get wrong, you've got wrong.

A lot of criminals use cheap Nokias.

They're of very little value.

They'll use it for a month and then pass it on to someone else deliberately to

try and thwart the police.

I want to know who's had that phone on the night.

The SIM card in it is unregistered. It's prepaid.

There's no user details recorded.

For me, it's a bit of a dead end.

I fast-track the Nokia phone.

I get straight on the phone to my lead forensic scientist.

Let's see whose fingerprints are on the battery, because that'll be the person

who took the battery out to put their own SIM card in.

There's good news.

There's fresh DNA on where the phone would be held to your ear.

and the mouse, suggesting it's the last person to use it.

There's also fingerprints on the battery at the back. So that's the best news

possible. I'm now going to know who's had that phone on the night.

And it's just a matter of putting it through our database.

But the fingerprints and the DNA aren't on there.

And that's quite a shock because now we're talking,

Someone was involved in a murder who's never had their fingerprints and DNA

taken by the police.

We do a fresh media appeal asking if anyone has got any information.

We start to receive intelligence.

A group were involved and they were from the centre area of Nottingham.

Somebody called us.

or YK, if identified in the inquiry.

Kashan Campbell, he's a 19-year-old youth.

He has been in trouble with the police before.

He's a knife carrier.

He's not the most prolific offender, but he's had quite a challenging

upbringing. His own dad was murdered when he was a child.

My questions are, what devices have they got?

Who are they communicating with? What phone numbers are they using?

With those numbers, I can apply for the call data.

It gives me the fastest amount of information that I can work on.

Who have they been in contact with?

Where have they been? The locations?

That day, the week before, three months before?

I want to know.

More about him. I want to link him to Lariko.

I'm going for the call data for Kashan Campbell.

Quite specific.

I wanted to know where this phone was, where he was, at this specific time, on

this specific date.

Bingo. Happy days.

He's in ballroom.

Right where I want him to be.

We've now got him in an area where there's been a murder committed.

There's three other offenders.

I want to know who else is with Kashan.

Every time your phone...

connects to a mast while you're travelling, it leaves a digital

footprint.

Your phone tries to shake hands with any public Wi-Fi, with any cell mast.

We then know Kashan's phone number, so we can say which phone mast

it pings off on what time.

We see that that pings off the same month, travelling in the same direction

at the same time, co-locating with the taxi driver.

Between 7.06 and 7.18, we've got three handsets co-locating

with the taxi driver's mobile phone, going to the vicinity where the murder

had taken place in Ball.

Who else was in the taxi?

Prashant's phone, the blue Nokia phone, which we'd expect.

And then there's a number linked to someone called Christian Jameson.

So another potential suspect comes into the investigation.

Again, I'm asked, who is he?

Tell me everything you know about Christian Jameson.

I find that he's involved in a knife-related incident. I could see

that... Kirsten Jameson had nicknames recorded on the system.

It was recorded with zeros.

And some of the supports were telling us he hung around with Kashan Campbell.

This feels like a really good breakthrough.

But once I show my hand, I lose the opportunity to do any covert work.

Other people involved might run away, might flee abroad.

Or start disposing of things.

It's really important to stay on the cutting edge of digital forensics

because actually the criminals do.

They're always adapting.

They're always transforming the way they do things.

And we live in a digital world.

When you're going through someone's call data, it can be thousands and thousands

of pages long.

You need to have an inquiry in mind.

We find out that the date of the murder, because Sean's phone is used up until

the minute before the murder, then it's switched off and then it's switched on

again after the murder.

Criminals think they're clever when they turn the phone off because they say,

I'll turn my phone off, then the police can't place me at the scene.

If I look at a suspect's phone history and I see that for the previous two

years that phone has never been switched off and, goodness me, on the night

there's a murder, nearby an area he is, he switches his phone off, well, that

tells me as much as it would have done if he'd have kept it with him.

Girl one was let go because there's just not enough evidence to charge her.

But we still have her mobile phone download.

When you're going through someone's download, it's a massively intrusive

procedure.

They can't contain fingerprint.

It can contain facial recognition. It's got photographs in. It's got your core

data history. It's got your contacts.

If it's a smartphone, it's got your applications that you use. You may use

social media applications that's on the phone. It retrieves all this

information.

My phone expert was reviewing all Girl 1's devices and said,

you're not going to believe this.

Girl one, she's been in communication with Kashan.

So that was a jaw-drop moment, because this is the first time I've got anyone

who links my two groups together.

So this was a really... Say that again.

And then he said, you need to look at this.

Moments after Lariko's death, Guild 1 tried to contact Lariko.

Are you okay?

Who was chasing you?

She's panicking.

They're unaware of how seriously fatally Lariko's been injured.

She's checking.

Are you conscious?

Have you named who was chasing you?

Loriko was 14 when he came to the UK to live with his dad and his sister.

I moved everyone here for a better life.

I wanted them to be able to experience university, college, you know, all of

those things.

When I arrived here three years later, Loriko had gone from my little boy to

this big man that was doing his own thing.

He didn't really need mum and dad for much.

I feel like he thought he had to be somebody he wasn't, being out here.

Yeah, I had only been here a few months and then he was stabbed.

Lariko's told me there's four offenders.

I now know Kashawn and...

Christian's phones are in Bulwell at the time of the murder.

I'm still looking for two more offenders.

A mobile phone is a movable item.

I could lend you my mobile phone.

You could lend me yours.

I could have put it in someone's coat pocket and they could have walked off

with it in their pocket, unknowingly had it on them.

So it's important.

that we put the device in a person's hand.

We go back to CCTV because we now know the point at which the offenders were

dropped off, picked up and taken home in the taxi.

We were aware that the taxi was going to pick up from Shrewsbury Road.

We'd start at that location and then just work our way out to try and track

the movement.

Around the area where the taxi's called, we see a group of youth coming from a

house of someone called Rommel Miller-Campbell.

Rommel Miller-Campbell is on a programme for youth who could go off

the tracks and he's on a football scholarship.

He was recorded with the nickname of Rem and had been linked to knife crime.

Christian Jameson and Remmel Miller-Campbell go into the pack

supermarket in Smenton.

Then Christian Jameson makes a phone call at 6.42.

Analysed the Cordage record.

Bingo. Happy days.

The timestamp on the CCTV identically matched the usage.

of Christian Jamin's mobile phone.

This is the same number, five out, travelling from Smenton, going to

Bulwark.

So to see that footage, the number that we'd said was his, pinging off the local

mast, and all of a sudden now I can put a phone in someone's hand that then

travels to the scene.

That's a real breakthrough.

I've now identified three males who I think are in the taxi.

Kashan, Christian and Ramel.

I've got evidence on camera of Christian Jameson on his phone just prior to the

murder.

I've also got girl one lying to me and I think she's involved.

So it's all coming together.

At this point, within the investigation, we're all feeling a little bit happy

now.

I'm going to arrest them.

I have three males in custody.

Kashan, Christian and Ramal.

I'm still looking for my fourth offender.

So what mobile phone then were you using on the 30th?

No comment.

Where is that phone now?

No comment.

You've been there?

No comment.

Ramel Andre Campbell-Miller.

Your phone is pinging off a mast in the Snesdon area and in

the Bulwell area.

And we're saying, that's you.

You're one of the people inside.

Lyrical.

They callously left him sleeping out.

I'm coming.

As I expect, none of them talked to us.

And I also have girl one in custody.

Were you put under pressure by anyone to meet Larika?

No comment.

How would they know that he's in that park if you didn't tell them?

Girl one is very significant.

It couldn't have happened without her.

That's the honey trap bit.

Some information suggests that you're involved in a conspiracy.

You've been named as someone that has arranged for Lurico to go to that park,

lured Lurico in so he could be attacked.

Why is that? Why are people saying that?

No comment.

Whenever anyone comes into custody, they're always searched, and because

Christian had previous knives and drugs, he was given a very thorough search.

And we found he'd inserted a phone in an orifice which wasn't made

for phones to be inserted in.

But obviously he'd put it up his back passage because he thought we wouldn't

look there, and we did.

Do you normally have a couple of phones on you?

So what can you tell me about the phone?

Is there going to be anything that links you to that phone?

This device, along with other devices, are interrogated and examined, and it

reveals some interesting search history.

There's five searches on Google searching the condition of a 17-year-old

boy that had been stabbed recently in Bulwark.

But interestingly, all these searches were deleted.

I think at this point, for Christian Jameson, the whole world's falling apart

and it's all about damaging imitation now. Do I need to get rid of my phone?

I'll just check on the internet to see whether or not, you know, they can find

me by my phone.

You've now got...

A group in a taxi travelling to the scene in contact with each other,

wondering if movements can be traced, and then later googling the murder.

It's getting harder and harder for them to explain.

Following more phone work, we got a really good breakthrough.

The most valuable piece of information and evidence that we got from Christian

Jamieson's phone was the blue Nokia handset.

was stored as a contact as a person by the name of JD.

That's the first time where we linked that number to any sort of name or

nickname.

I asked my phone expert to go back to the place where the blue Nokia cell

site's from and see where it locates prior to the murder.

So... The blue knocker that the offenders have left in the back seat of

the taxi is self-sighting to an address in Smenton before the murder.

And the person that we now know to have the initials JD,

their home was within the self-sight triangulation.

JD was 16, so a child.

JD's arrested.

We bring him into custody.

I know time isn't on our side because we've got the 24 hours.

And the first thing is, when he goes into custody, he's taking his DNA and

his fingerprints.

They have officers with their engines running.

The fingerprints go to one lab.

The DNA goes to another.

We've got scientists being paid overtime to turn that round on the 24 hours he's

in custody.

So the clock's ticking.

I was in the incident room and all my team were there.

I think I just opened the email and said, Oh God, it's him. It's him. We've

got him.

You're... Forensic evidence on the phone.

You've got fingerprints and DNA on that phone.

You got anything to say about that?

The odds of that DNA belonging to anyone else other than JD

were a billion to one.

It felt really, really good to charge.

the fourth person it was all the digital evidence brilliant detective work by the

team we'd gone from a whodunit to having all the offenders

in custody

i

can remember

driving home that day and sort of being quite elated.

But then the next day you're back in and you're like, right, let's start building

this file.

I know we've got the right people, but I need to convince the person who walks in

off the street and sits on the jury.

We're still missing one major thing.

We're missing a motive for why this terrible incident occurred.

And this is really important because it's one thing to say to a jury, these

are the right people, but they say, but why?

Why would they do it?

We still haven't got Larico's phone at this stage and we

all believe that some of the answers could be on there.

We do a fresh media appeal.

Lo and behold, one of his friends contacted the police and handed over the

damaged mobile phone, claiming it was Larico's.

This phone was in such a state that it had to be rebuilt and then interrogated.

It contained some very interesting social media videos.

One in particular.

shown the backs of two people running away down a street, and with a

comment on it by La Rico, under the caption, Runners, Rems and C-Rows.

La Rico's group were shouting after them, athletes, athletes, gang athletes,

and mocking them as they ran away.

Come on, hold that gang shit, man. Come on, we're out here, B, out here, out

here, out here.

And then at the same time, we received intelligence that we should be looking

on YouTube for some videos.

We found two videos that have been uploaded onto YouTube, one by Lurico and

his friend, and one by the suspect.

On the first video, we saw Lyrico standing at the back of the group.

He's a minor player.

He's not one of the singers.

On the track, again, they talk about rems

and zeros and cash.

and they refer to them again as the athlete gang.

They're actually dancing like this, running, innit?

Basically they're calling them cowards.

Kashan and Christian's gang ran away and they're mocking them.

That is massive, massive disrespect.

And then the final piece to the jigsaw was a video.

On YouTube.

Made by the Way Too Gang. The lead singer, and it was Kashan, we know that

for sure.

They use the word, anyone

calling us athlete gang is going to get Rambo'd.

And they talk about stabbing someone in the chest. Stabbing someone in the back

and putting him in a hole.

But they're not stupid enough to name Lariko.

When I look at this and listen to what they're saying, they're describing

Lariko's death, it just feels like they're bragging.

We're talking about very young adults here.

For someone to die over that, it's crazy.

It's crazy.

These weren't organised gangsters.

They were kids who wanted to sing and pretend to be gangsters.

Obviously, they just lost the concept of reality.

But they were all in it, not a single one of them said, this is the wrong

thing to do.

When I think about Lariko's mum, I've got nothing but.

admiration that to this day, five years on, she is still out there telling

people what it's like to be the mother of a murdered child.

As the days go past and the years go past, the pain doesn't go.

I decided to move.

After we go past.

I wanted the girls to start fresh and just feel free and safe.

It really helps me to talk about them.

I don't want my son's name to just fly in the wind.

Some people get nervous to speak to me about their children, especially

their sons, but I've reassured them, please share your stories. Please tell

me how good your son done in school today. Please tell me how much closer

you've gotten to him.

Just hug your son a little bit more for me.
