All language subtitles for Cold Case Killers S01 E05_track3_[eng]

When a murder
is left unsolved...

No weapons, no eyewitnesses,
no forensic evidence at all.

There was nothing.

..And a killer is
on the loose...

These people are still out
there. Who's going to be next?

..Britain's cold case
detectives will never give up.

The best way to solve a
cold case is to keep it warm.

No matter how long it takes...

This case dominated my life.

..They'll investigate every
angle and follow every hunch.

Searching through
thousands of people.

They think they've got
away with it. You haven't.

..Until justice is finally done.

We all leave a trace.

We finally identified
that golden nugget.

Bingo, we've them.

Thursday, October 1st,
2009, the quiet market town

of fakenham, north Norfolk.

Valerie tuck was visiting her son,
Steven Murphy, and discovered

a scene that is every
mother's worst nightmare.

Her son lay dead in his hallway.

With his shirt covered in
blood, Valerie could see Steven

had been violently killed.

Shocked and
distraught, she called 999.

Emergency, which service?

Detective chief inspector jes fry
was part of Norfolk and Suffolk's

major investigation team.

On his way back from
a police conference,

he was alerted straight
away to this potential murder.

I had a phone call to
tell me that Steven's body

had been discovered in fakenham,

and so I diverted to
come straight to the scene.

Jes was an hour's drive away.

While he raced to fakenham, he
sent local officers to secure the scene.

Steven's neighbour, Todd gilbey,
couldn't believe what was happening

right on his doorstep.

I lived just around the
corner from Steven Murphy.

I used to see him all the time.

He seemed a very sort of
calm, quiet, reserved guy.

I remember coming home from
uni and there were crime scene vans

literally parked up in a
row over the entrance here,

and I remember them checking
these two drains for murder weapons.

It just looked like something out
of, you know, out of a TV show.

I'd never seen
anything like it before.

Steven's mother,
Valerie, was distraught.

Her sister, Steven's aunt
Jane, rushed to her side.

I went down and we all just
sat there staring at each other,

just saying, "this
can't be true."

And she's telling me
how she found him.

And she pushed the door
open and Steven's body

was behind it in
a pool of blood.

I can't imagine that.

I just can't imagine how
she lived with that image.

I have that image
that I didn't even see it.

Steven's family couldn't comprehend
how someone so easy-going had met

such a violent end.

Steven was fun, and he was
smiley and friendly, and people

just liked him when they met
him because he just had this nice

way with him.

When jes fry arrived, crime scene
officers had already begun building

a picture of what had
happened inside Steven's home.

Jes had the unenviable
task of speaking to the person

who had discovered
Steven's body.

After I'd visited to the scene

and then spoken to
some of the local officers,

I went to visit Steven's
mother at her home.

She was a lovely lady, really
engaging, and I felt a real

connection with her.

It put pressure on me later
on, but I sort of made a promise

to her that I was going to find
Steven's killer, and I was going

to get a result
for her, if you like.

I didn't want to let her down.

I think I've investigated over 50
murders, and I don't think I've ever

made a promise to
anyone quite in that way.

I really felt as if I needed
to do something for her.

We believed him.

I believed him and
she believed him.

I really did think they'd
find out who'd killed Steven.

The news of Steven's brutal
death quickly spread through

the local community.

To have something like
that happen, especially

in a small place like fakenham,

it's the last place you
expect to find a murder.

So obviously it's headline news.

We heard that it was the mother
who discovered that her son

had been murdered when she'd
just called it the address, having not

heard from him, which is very
unusual because they were

in daily contact.

And of course, she arrived
there to find this terrible scene

of her son lying there,
stabbed to death.

It was incredible.

You know, nothing ever
happens in fakenham.

It's a very, very quiet,
safe place to live.

Jes and his team of detectives
began looking into Steven's life,

hunting for clues to anyone
who had a motive for killing him.

Most often, a murder is committed
by someone known to the victim,

and so it's really important to know
as much as you can about the victim

in order to make those links.

With help from his family,

jes quickly built up
a profile of Steven.

Steven was a 45-year-old man

who'd moved to the fakenham
area fairly recently from southampton

to be closer to his family.

His mum, his uncle,
who lived in the area.

Steven came from a lovely family

and he'd had an accident
early in his life that seemed

to change his nature.

And following that, he had become
involved in drugs and his family

were trying to give him a new start
and bring him out of the situation

that he was in in southampton

and to be close to
them for their support.

Steven's move to fakenham
seemed to have had a positive effect,

and he had become
close to his uncle, Ken.

I was really pleased that he did
come up here and he was ever nearby.

He was very pleased to be
near to his mum and his stepdad.

We spent some time socialising.

I introduced him to some people
and he found some nice friends here.

He liked talking about
football. He liked music.

He was good friends
to people, I think.

And he was, you
know, good fun, really,

most of the time, I would say.

As the investigation continued,
jes received some strange news

from the forensics team.

Steven lay in a foetal
position on the floor.

There was blood around his body
and blood on the wall next to him.

Despite the blood around him,
it was strangely sterile in that

obviously, something very
violent had happened at the end of

the corridor, but there was
nothing leading up to him,

nothing leading away from him.

A brutal murder with barely any
forensic evidence was practically

unheard of.

When a victim
receives stab wounds

there is quite a potential there
for a lot of forensic evidence, so

the offender has been really
close to the victim physically.

They have interacted with them.
They have touched their body.

They may have
their blood on them.

So to actually leave no evidence

is something that's
quite difficult to do.

The most shocking thing was
that there was no fingerprints,

no DNA, nothing that you would
normally associate with a bloodied

crime scene, which only
added to the mystery of it all.

There was only one
clue left at the scene.

Officers discovered a mysterious
Mark just outside the house.

There was nothing from him
all the way down the hallway

until there was a footprint
in blood under the porch,

just outside the front door.

It was so unusual, it was
almost unexplainable at the time

because if someone had something
on their foot, they would have

tracked it down the hallway.

And so, how did they suddenly
have blood on them outside?

With no murder weapon, no
suspect, and no forensic evidence,

the promise jes made to Steven's
mum looked far from being fulfilled.

In October 2009, Steven Murphy
was stabbed to death at his home

in the quiet market town
of fakenham in Norfolk.

Newsreader: Norfolk police are
still looking for the murder weapon.

They haven't made any arrests.

They want members of the
public to tell them anything

they may have heard
about Steven Murphy.

With almost no forensic
evidence at the crime scene

detective chief inspector jes
fry and his team had to rely

on more traditional
investigation methods.

A key line of inquiry is
house-to-house enquiries -

to go around all the neighbours,

everyone within that close, to
identify potential witnesses who

may have seen
something significant.

House-to-house enquiries identified
some neighbours just across the road

who had just finished watching
EastEnders and came out and saw two

figures just outside
Steven's front door.

That gave us a time where
two people were at the address

that we could focus on.

This witness account helped
jes focus the investigation

on a specific time.

He put together a specialist team
of police search advisers known

as polsa to hunt for any
clues in the immediate area.

It's always possible that the
weapon may still be at the scene.

It's possible that it could be
discarded when someone is running

away from the scene,
or leaving the scene.

We had a polsa search team do
a search leading from the house

and then around the close
and down to the main road.

And then we gradually
extended that perimeter.

The neighbourhood was still
reeling from the shock waves

of Steven's murder.

I remember feeling, is this really
as safe a community as we thought

it was, you know,

and it was a case of
being a lot more aware

of my surroundings when I left
the house because we didn't know

if this was as random - a
random killing - you know,

or is there somebody going
around killing people randomly?

Even more shocking were the
chilling details of how Steven was killed

revealed by the
pathologist's report.

During the postmortem,

it was established that Steven
had been stabbed 16 times.

Attacks with a knife are not
uncommon, but generally speaking,

it would be one stab wound.

But this did seem a particularly
violent attack, with further

injuries that were cause
clearly after he was on the floor

because they were around
his body, in his buttocks,

in his back, and the assault went
on longer than it really needed to.

This is a particularly violent
murder, a rare instance of such

severe violence inflicted.

Many of us would simply
find it insurmountably difficult

to inflict that much pain,
both physically and emotionally

on somebody else.

So it's a rare instance to
find this severity of violence.

When we look at a case
where there are 16 stab wounds,

there is a tendency to use terms
like frenzied or out of control.

But actually, what's going
on here is that the offender

is very much in control.

This is a performance.

This is a way of communicating
something about the killing.

It's a way of communicating
something about the killer.

Look at me. Look at how
much violence I'm capable of.

The painstaking searches
made by the polsa team also came

up empty handed.

With no weapon,
forensic evidence,

motive or suspects,

police had to broaden
the investigation.

A media appeal was
made, led by Steven's uncle.

Somebody may have seen
something in the area at the time.

They may have seen something
unusual, and they have not

yet come forward,
for whatever reason.

Someone might know
who's responsible for this.

Please contact the
Norfolk police now.

Ken was the public face in the press
and on the TV, and he volunteered

to do that to protect
the rest of us.

And that was very hard for
him and it was very difficult.

Although the investigation
had so far drawn a blank,

Steven's family never
lost faith in jes fry.

I mean, jes just comes across
as somebody that's very capable

and very strong, and he knows
what he's doing, and he's got a big

team of people working for him.

So I had absolute complete
confidence in that man.

And all of them, really.

The appeal for information did
raise hopes of a breakthrough.

Someone informed us that
they had seen a car driving

out of fakenham, and seen
something thrown from the car.

It was always a possibility
that it could be the murder

weapon being discarded.

And so we sealed that area
and did a fingertip search

and we did what we would
call anniversary checks.

People are very
habitual in what they do.

We've got a time to focus
on where these two people

are outside the front door.

And so, who else might
be in that area at that time?

And could they have
seen something?

Had they seen a
car that was unusual?

Had they seen someone
running away out of the close?

But hopes were quickly dashed.

It turned out that nothing was
found where something was discarded

from the car.

Undeterred, jes
refocused the investigation

back inside Steven's house.

With an attack this violent,
there had to be some forensic

clue he'd overlooked.

Forensic evidence is
key to every investigation.

It's very strong evidence,
because if there's DNA,

then you're looking at a one
in a billion chance of it being

someone else and it's really
strong, and you hope that you'll find it.

The most puzzling thing was
how there could be nothing

evidential between the footprint
outside the front door and Steven's

body at the other
end of the hallway.

All the evidence was
sent off for examination.

We look at, sort of, luminol
to identify blood or some other

substance that will identify
blood that is not obvious

to the naked eye.

Fingerprinting and other, sort
of, chemical techniques used to try

and bring evidence forward
to try and identify any DNA

that may have been left.

Fibres, hair, sort
of, anything like that.

Within days, the results came
back and confirmed jes's fears.

At the end of the examination,

there was no forensic evidence
to link the victim to his attacker.

It looked like every Avenue
jes tried was hitting a brick wall.

It's really important to keep
an open mind and think of other

avenues to secure and
harvest evidence that will assist

a successful prosecution.

Unable to rely on science,

jes had to hope his police
experience and instincts

would be enough to
catch Steven's killer.

We spend a lot of time today talking
about forensic techniques, talking

about technological advances,
DNA, cell site analysis,

that kind of thing.

But most murders, what's at the
core of those getting solved is good,

old-fashioned police work.

It's door to door enquiries.

It's asking questions.

It's believing nobody.

It's checking everything.

Those kind of skills are what
will solve many of these crimes.

Yes, the technology and the
science can assist in an investigation.

But if you don't have that good
philosophy at the heart of it,

it's not going to get very far.

As jes and his team continued to
uncover more about Steven's life

in fakenham, one particular
piece of information stood out.

The investigation into Steven's
movements in fakenham identified

a feud that had begun between
Steven Murphy and a man

called James Cameron.

It would appear that there was an
argument between them over a lady

in the town.

Possibly James Cameron had
been in a relationship previously.

Steven became friendly with her.

There had been a confrontation
and, in fact, Steven had been arrested

for an assault on Cameron,
where mr Cameron received a cut

to his hand from a knife, for
which he was charged and later

tagged, as well as
other tit-for-tat incidents

from Cameron towards Steven.

Finally, jes had a suspect
who could have a motive

for killing Steven.

Although the injuries
from the previous fight

were relatively minor,
they had an altercation

over a relationship.

And it might be that there were
feelings of anger, frustration,

annoyance and a clash.

He may have experienced feelings
of rejection, shame, humiliation,

and this might
have sparked anger.

James Cameron was a long shot.

Although he lived in Scotland,

he often visited
family in fakenham.

James Cameron came to
fakenham for a family reunion

for his brother's birthday.

And so we took the opportunity of
speaking to him and spoke to him

about his movements
and the relationship

that he'd had with Steven Murphy
and how it had become antagonistic

and what had been going on.

Cameron was cooperative.

He claimed that on the day of
Steven's murder, he was hundreds

of miles away at
home in Scotland.

Jes was suspicious and didn't
want to let his only suspect go

without checking his alibi.

What we did do was we seized
his mobile phone and issued him

with an alternative phone so
that he still had access to one

but so that we could look
at the data that we could get

from his phone to identify anything
that may link him to the inquiry.

Mobile phone analysis is a key
element of every investigation,

and at the time of this
investigation, it was quite new.

We were able to obtain
recent telephone calls made,

recent telephone calls
received, text messages.

His phone would also prove
where he was on the night

of the murder.

He was in Scotland when
we looked at him closely.

And so he had a cast iron alibi
and could not have been in fakenham

at the time of the murder.

The murder of Steven Murphy
in the Norfolk town of fakenham

had left dci jes fry and his
team completely baffled.

Virtually no forensic evidence
had been found at the scene,

and extensive enquiries
showed that their only suspect,

James Cameron, had a cast-iron
alibi for the night of the murder.

So where we had started off
with a broad ranging inquiry

and become very interested in
James Cameron, we came to a point

where we had virtually
eliminated him from the inquiry.

There was nothing on his
phone that we'd found to that time.

Jes had no other
avenues of inquiry.

All he had was Cameron's
confiscated mobile phone.

He decided to have it further
analysed for any deleted data,

a practice that at the time
took months to process.

There were no other obvious
people that could be possible, suspects

and things started
to get really difficult

finding new evidence and
new lines of inquiry to pursue.

With no new leads in fakenham,

jes also decided to
look further into Steven's

past life down in southampton.

We sent a team of
detectives to southampton.

They probably stayed down there
four to six weeks interviewing associates

of Steven, friends, people
that he had been associated

with by the police
in southampton.

And so we looked at those people
and where they were at the time,

and did they still have
a grudge of any sort.

On a hunch, jes explored
a theory that Steven's killer

could have driven from
southampton to fakenham

on the day of the murder.

I thought one of the best ways to
try and identify whether someone

had travelled from southampton
to Norfolk was to look at automatic

number plate recognition data -
anpr data - of vehicles that had left

southampton, travelled to Norfolk,
and then travel back to southampton.

Anpr cameras register every
vehicle on the road, creating vast

amounts of data.

By this time, we had a timeline
around when we thought that Steven

had been murdered, and so
we were able to put in parameters

for the anpr data, but it
still contained thousands

and thousands of vehicles.

And so we needed to refine
that down by introducing

the parameters and the
vehicles that had to have travelled

out of southampton into Norfolk,

back the other way, then eliminate
lorries and that sort of thing.

We came to around
about 100 vehicles.

So those vehicles were then
looked at individually until eventually

we eliminated everyone that could
possibly have left southampton.

Jes had hoped for a
breakthrough, but his southampton

enquiries led nowhere.

We were trying to think of different
opportunities, but everything seemed

to be coming to a dead end.

The contacts that he had in
southampton were eliminated.

Looking for other links to other
people and expanding those

concentric circles around
Steven to identify other people

that may have come into his life

was all proving negative,
and it was getting difficult to find

somewhere new to
go with the inquiry.

We did think initially that
they would find out who'd done

it much quicker because, you
know, you just think they must

have left some evidence and some
clues, and somebody would be able

to work it out.

But then after a while,

they just kept
drawing full stops,

at all the avenues

they were following up.

And yes, it did
feel that there was

just this big black
hole and somehow

whoever had killed him

had disappeared
into it, and maybe

they had got away with it.

When it did seem as if
it had come to a full stop,

a family member felt that it
might be helpful to offer a reward

of £10,000 in case that was
the tipping point for somebody

who knew something.

Someone else must have
known what was happening.

Someone else must have
suspected what was happening.

And so we concentrated our
media campaign on the areas

that we could link Steven to.

Again, nobody came forward.

The inquiry had already generated
three times the amount of actions

of a normal murder
investigation.

But the case was running cold.

There was no murder weapon,
no forensics, no suspects.

It really looked like it was
just going to go nowhere,

the investigation, and as it
dragged on, it looked even

less likely that there
would be any arrest.

It was becoming very frustrating
because we didn't seem

to be actually going anywhere.

What we were doing was eliminating
a lot of things, but we needed

to find that golden nugget.

Months had gone by
with no arrests made.

The people of fakenham
were losing hope.

I remember talking to some
neighbours about it at the time

and they were saying, you know,

"I think this is going
to be a dead end."

You know, "I don't think the
police are ever going to solve this."

You know, "this has been going
on for such a long time now."

But jes and his
team never gave up.

And Steven's family
still had faith in him.

We had a brainstorming session to
try to think of new ideas, new ways

of where we could find
the great silver bullet.

I think there was another
murder somewhere else

in the county, and you think,

well, they're going to focus
on that now, aren't they?

Perhaps they'll just
forget about Steven.

But then I thought, no,
they won't. They won't.

And they didn't.

I mean, we never lost
hope, and we always felt

that it was the good,
old-fashioned police work of working

through things that eventually
we'll come across something.

And then, after all the dead ends,
at last, jes got the breakthrough

he'd been waiting for.

The data on James
Cameron's phone finally came in.

There were several things about
the activity on James Cameron's

phone that brought him straight
back to the front of our minds.

So there were some texts
that were sent, particularly

a deleted text on the evening
of Steven's death that came back

saying, "good job."

But there was a flurry of telephone
calls at certain times that seemed

key to the investigation.

And some of those numbers
hadn't yet been identified

because they were
from prepaid phones.

And so, there was a
new impetus to try to find

who it was that he was
having these phone calls with.

After so many dead ends in
investigating Cameron's story,

this could be the slip-up
he'd been hoping for.

Cameron handed his phone
over to the police readily.

He just gave it to them

because he was convinced
that he'd removed anything

incriminating from that device.

But actually, the only
thing is that deleting is not

the same as removing.

When something is deleted, it's
only deleted for as long as it takes

someone who knows what
they're doing to recover it.

Police had given Cameron
a replacement phone,

and the data on that
was also damning.

So one of the first calls made
by James Cameron when he left

the interview on the new phone,
we'd issued him to was to a number

that appeared on
his other phone.

But as soon as
that call was made,

the other phone stopped being
used completely, and so the inference

there is that James Cameron
has told the other person they know

about this phone,
you need to get rid of it.

They were able to
pinpoint the exact location of

the phone Cameron called.

We were able to
establish that the phone

connected to the telephone
number that James Cameron

had been contacting
had been in Blackpool,

was in fakenham on the night
that Steven Murphy was murdered,

and remained in fakenham
till about 9pm that night

before returning to Blackpool.

James Cameron went from
person of interest to prime suspect.

The further inquiries into
James Cameron identified

that he had actually had
a son, Andrew Cameron,

who moved to the Blackpool area.

After months of frustrations,

finally, things were
coming together.

And jes and his team quickly
expanded their investigation

to include Cameron's son.

Having established the link between
Andrew Cameron and the phone

and the fact that Andrew
Cameron was in Blackpool,

inquiries started
with Blackpool police,

to find out what they knew
about Andrew Cameron.

They were able to link him to
a gentleman called Alex Dewar.

Alex Dewar was currently
on remand at Preston prison

for a very serious assault.

Andrew Cameron's friend,
the 24-year-old Alex Dewar,

was not only a man
capable of violence,

he had also studied
criminology at university.

The study of criminology involves
a vast array of different subjects,

including how and why
offenders commit crime,

and how different elements of
the criminal justice system operate.

It can also involve an
element of forensic science

and how crime-scene
investigation operates.

Dewar's knowledge of
criminology could certainly explain

the total lack of forensic
evidence at the crime scene.

Police looked more deeply
into this third suspect.

Dewar had a vehicle.

The registration number was
put into the anpr system and,

all of a sudden, we had
Andrew Cameron's phone.

Alex Dewar's phone being used
and identifying the telephone masts

on the route between
Blackpool and fakenham.

We had Alex Dewar's car
identified by anpr on the route

coming into Norfolk.

The pieces were
falling into place,

and jes's promise to Steven's
mum might not be broken, after all.

Well, there is a sense of
euphoria, without a doubt,

when it all starts
coming together.

We had been trying to resolve
this case for months and,

all of a sudden, all the
dominoes started to fall

and it got very exciting.

The next task was to locate
James Cameron's son, Andrew.

We identified that Andrew Cameron
had been in relation with a girl

in Blackpool, and they had
moved to Canada together.

In a rare piece of luck,
jes found out exactly

where Andrew Cameron was.

As we were looking into Andrew
Cameron, we established that

he's actually on a
flight back from Canada,

so I dispatched a team to meet
the aeroplane and to arrest him.

He was brought back into Norfolk

and went to the first police
station we could get to.

One of the key things about
dealing with someone in custody

is to manage their
custody time clock.

You have a limited amount
of time to deal with someone

and to ask questions and
try to build your, your case.

With the clock ticking, jes
needed to get a result, and fast.

He denied any involvement in
the murder of Steven Murphy.

He denied having
come to fakenham.

Though his phone, by that
time, could be located as being

in fakenham, he may not
have been in possession of it,

and he said that he may
have left it in Alex Dewar's car.

And, therefore, we couldn't directly
link Andrew Cameron to the murder.

We consulted cps and we were told
that we didn't have enough evidence

to charge at that point
and he should be bailed.

So, Andrew Cameron
returned to Blackpool,

and our inquiries continued.

After months of false
leads and frustrations,

and without any forensic
evidence, dci jes fry's investigation

into the murder of Steven
Murphy had turned a corner.

James Cameron's phone
had finally revealed its secrets.

Now, police had
two more suspects -

Alex Dewar and
James's son, Andrew.

Jes now focused
his attention on them.

I sent a team of detectives
to Blackpool to start looking

more deeply into Alex
Dewar and Andrew Cameron.

And we identified several
witnesses who said Alex Dewar

had bragged about
being involved in a murder,

which they thought
was just bravado.

They just thought that he was
lying and just making things up.

Dewar was already on
remand for a serious assault.

He was taken from Preston prison

and formally interviewed
at a local police station.

Alex Dewar made no comment
throughout the interview process,

no matter what information
or evidence we put before him,

and he was returned
to hmp Preston.

Not long after he returned,
he asked to make a phone call.

It was significant that he had
actually asked to use a phone

in an office rather than the normal
phones that the prisoners use.

I think he felt that there was a
good possibility that the office

phones weren't recorded the same
as the phones that the prisoners

would normally
use, but they were.

When Dewar called his
friend, the police were listening.

So, during the conversation,
he actually commented that

he thought that Andrew
would drop him in it,

and he became really quite
emotional and started crying.

He was clearly affected
by the sudden interest

from the police, and realising that
things may be coming to a head.

The net was closing
in on Alex Dewar.

Jes now turned his
attention to Andrew Cameron.

I made the decision that we
should actually make a telephone call

to the girlfriend in Canada and,

so, my intelligence sergeant
is also a trained negotiator.

There was an afternoon in
the office where we cleared out,

and it was just two or three of us
present when he made the phone call

to, to the girlfriend.

And she disclosed
that Andrew Cameron

had told her that he had
been involved in the murder

and had travelled to fakenham
to murder Steven Murphy.

It was exactly the kind of
evidence against Andrew Cameron

that jes and his team needed.

There's a bit of a tingle
goes down your spine

when certain things happen.

Obviously, the situation
was very controlled,

and so there's an
excitement inside,

but you've got to
remain very focused.

But, certainly,
after the phone call,

we shared a little
bit of a celebration.

Jes now needed to conclusively
place Cameron and Dewar

in fakenham.

Further investigation into Alex
Dewar identified bank accounts

that he used, and a transaction
on his current account was linked

to a withdrawal at a cash
point in fakenham town centre,

on the evening that Steven
Murphy was murdered.

Cctv images left no doubt.

Andrew Cameron and Alex Dewar

had claimed they'd
never been to fakenham,

but the cctv footage of
them using the cash point

put them in the place they
claim they'd never visited.

Armed with a mountain of
evidence, jes continued digging.

Whilst Alex Dewar
was being investigated,

we carried out a search
at his home address.

And during that search,

a pair of lonsdale trainers,
size 12, were found -

the same size
and make of trainer

that made the footprint
outside the front door

at Steven Murphy's address on
the night that he was murdered.

Jes now had enough evidence
to re-arrest Andrew Cameron,

but he still needed to link the
case to Andrew's father, James.

When we re-arrested Cameron,

we'd searched the flat
that he used in Blackpool

and, in the address,
we found a computer.

That was later analysed,

and we could show that Andrew
Cameron had been searching

route finder maps
for travel to Norfolk

at exactly the same time
that he was talking to his father

on the telephone in Scotland.

This was the
evidence jes needed.

He finally had enough to charge
all three men with Steven's murder.

So, everything was
really stacking up,

and we went back to cps,

who agreed to the charges that
were laid for Andrew Cameron,

Alex Dewar and James Cameron,

linked by the telephone calls

and the computer activity.

After months of painstaking
police work, in march 2010,

all three suspects were
charged with conspiracy to commit

grievous bodily harm,

whilst Alex Dewar and Andrew
Cameron were also charged with murder.

The news soon spread around
fakenham's tight-knit community.

When I found out that
arrests were made,

I was really relieved
for not just his mother

but for all of his family,

that they were able to
finally start to get closure

over what happened to Steven.

The key to solving this whole case
had been the three conspirators'

trail of digital evidence.

So, there are two types of
digital footprint that are left behind.

There's those from your
own, personal devices -

from your phone,
from your tablet -

and then there are those
from other types of surveillance

that you aren't in control of.

So, cctv, anpr - automatic
number plate recognition -

transactions in shops.

So, I think there is this arrogance
on the part of some offenders.

They are quite savvy when it
comes to physical evidence,

in terms of trace evidence left at
a crime scene - DNA, blood, hair -

but when it comes
to the digital evidence,

they really don't know
what they're doing.

In November 2010, the
trial of Andrew Cameron,

his father, James,
and Alex Dewar

began at Norwich crown court.

In 25 years of covering court,

this case stands out in my mind

just because of all
the twists and turns,

and how the dogged police
work eventually paid off

to help catch killers.

On December 15th,
2010, after six weeks,

the jury came back with a guilty
verdict for all three defendants

on all charges.

They thought they'd
done the perfect murder.

So much so that they couldn't
help bragging about it to friends,

girlfriends.

But, in the end, it
caught them out.

It proved that they didn't do
the perfect murder, after all.

It was vindication
for dci jes fry.

I felt, actually, a little bit
emotional in court when they gave

the verdict, because I'd finally
made good on my promise

to Steven's mum.

But it was a huge relief
because it had been a long,

hard inquiry with various
ups and downs throughout it.

But it was a really
positive feeling

and something that all of
my team could celebrate

because they'd all contributed
in various different ways

to a really difficult inquiry.

A few days later, all
three men were sentenced.

Alex Dewar and Andrew
Cameron were given life

with a minimum
tariff of 25 years,

and Andrew's father,
James, was given 15 years

for conspiracy to cause
grievous bodily harm.

The verdicts were a bittersweet
moment for Steven's family.

It was a twofold feeling
because it's that feeling

absolutely sick and,

erm, a bit of elation, actually,

that perhaps this is all,

this horror is all going
to come to an end.

Jes fry kept his promise to val
because the killers were found

and they were
brought to justice.

And they've got an awful
long time to sit in prison

and think about what they
did, and I hope they are.

And we will be forever grateful
to jes fry and the Norfolk police

for doing that, for
Steven and for us.

After 30 years
investigating serious crimes,

jes is now retired.

But the case is not forgotten.

Different investigations stay
with you for different reasons.

My connection with mum
made this particularly special.

The fact that it was
a difficult inquiry

and there were so many
different aspects of it

makes it very memorable.

An innocent night
out ends in tragedy...

He was an ordinary lad,

just out socialising.

..And starts a mystery
that takes over 25 years

of dedicated
police work to solve.

When we know we've got
the man, that's a great result.
