When a murder's committed, it's always a race against time,

to find the truth, to separate fact from fiction, to catch the killer,

and to make sure that justice is served.

But what happens when the truth vanishes with the victim?

I'm Dr Richard Shepherd, and I've spent my entire career

as a forensic pathologist, performing nearly 23,000 autopsies,

including on some of the most high profile cases of recent times.

I've learnt that the dead don't hide the truth, and they never lie.

Through me, you'll be hearing directly from the victim

from a state-of-the-art laboratory with ground-breaking technology

that uses digitally scanned sample bodies.

I'll be investigating a series of intriguing murders,

where from the victim's bodies, I'll be revealing to you

the truth behind those horrific crimes.

(camera shutter clicking)

(tense music, siren wailing)

Late at night on the 6th of January, 2013,

58-year-old Peter Fasoli was found dead in the burnt-out remains

of the small bungalow in London where he lived alone.

That evening, neighbours had been alerted

to a fire alarm at Peter's house.

(siren wailing)

And called the fire brigade,

who came and extinguished a house fire at his address.

Sadly, within the house, Peter was found to have died.

During a subsequent investigation,

it was concluded that the house had probably caught light

due to a faulty light bulb fitting

that had fallen down onto the bedding

and caused the fire.

(Richard) 'A report by the fire service said it was an accident,

but was it?'

'For almost two years after the fire,

a silent witness lay dormant, waiting to be found.'

'While the extraordinary true story

of how Peter really died lay hidden within his body.'

'Peter Fasoli was born to an Italian family in Manchester,

where he lived most of his life.'

'But he'd moved to London in 2012,

where, at the age of 58, he lived by himself.'

He lived in a small bungalow in Northolt in West London.

(gentle music)

He worked as a sort of IT consultant,

sitting in front of a computer at home all day,

which meant that his social interactions were quite limited.

Mainly, he met people over the Internet.

Peter Fasoli was a quiet man,

kept himself to himself, lived his own life.

No long-term relationships,

reached out online to make friendships and to arrange dates.

By all accounts, was a happy individual,

living his life the way he wanted to live it.

He didn't have an awful lot of contact with the outside world,

and he didn't have an awful lot

of very close relatives living nearby either.

So, he was fairly isolated from the community.

But he was a kind of person who did crave interaction with people.

He would quite often

seek out young gay men for company...

...and also for sexual encounters as well.

We know that Peter had made use of an online dating app to meet others.

It was one of these dating apps that in January 2013,

he met a man calling himself Gabriel,

who he invited to his house.

They'd arranged to meet at his bungalow in Northolt

on the evening of the 6th of January.

According to the messages that had gone to-and-fro,

Peter was expecting some sort of sexual encounter.

It seemed as if the person

he'd connected with on this website fitted the bill.

They seemed to be into the same things,

and this person who went by the name of Gabriel had said,

"Well, I'm going to come and we're going to engage

in this sort of role-play activity."

So that was what Peter Fasoli was expecting.

'They agreed that Gabriel would come to Peter's house

at 7pm on the 6th of January.'

On the morning of 7th of January,

Peter received some text messages from Gabriel.

Gabriel was apologising for not having turned up

to their appointment the night before,

and exploring Peter's availability for future meet-ups.

And then some more messages later on

saying, "Oh, why are you ignoring me?"

So clearly something has gone wrong, according to these messages.

(tense music)

But Peter never read these messages.

(fire alarm beeping)

Very late on the 6th of January,

going into the early hours of the 7th,

Peter Fasoli's fire alarm goes off,

and the emergency services are called.

(siren wailing)

He's found in the house, collapsed, and he's pronounced dead.

Initially, it does seem that the fire was an accident.

There had been an initial investigation

that identified nothing suspicious.

The death, go through the usual process, there's an inquest,

which confirms that Peter's death was an accident.

'There was a post-mortem examination of Peter's body

to see what it could reveal about his final moments.'

Peter's charred body was found in his bungalow, and at the time,

it was thought that there were no suspicious circumstances.

But the cause of death still had to be determined.

I've examined many fire deaths in my career,

and I know that within a domestic fire,

temperatures up to 800 degrees Celsius,

that's 1500 degrees Fahrenheit, are easily achieved.

So, the hot gasses themselves can cause death,

but the crucial things that kill are the smoke and the fumes.

These cases cause problems for any pathologist who has to examine them.

They have to consider a whole series of things.

They've got to establish the identity, the cause of death,

but particularly they've got to try and work out

whether the person was alive at the time the fire was burning.

We look into the air passages, the trachea, the bronchi and the lungs,

and this image shows what you find at post-mortem.

The black soot and debris

distributed throughout those air passages,

and if we can find soot and heat damage in the airways,

we know that the person was alive at the time the fire was burning.

(mysterious music)

'The evidence suggested there was no doubt

that Peter was still breathing when the fire had started.'

(fire alarm beeping)

'And it seemed that the cause of death was clear.'

Peter had some health issues.

Erm, he had a heart condition and at times needed the support of oxygen

to help him breathe and get about easily.

The conclusion was that Peter had inhaled some smoke

during the initial stages of the fire,

that that had triggered problems with his heart condition,

and that he had died as a result of a heart attack.

That is what the police decided,

based on what the fire brigade were saying.

So, really, they didn't take things any further.

They didn't look at the wider circumstances of Peter's death.

'After the inquest in August 2013, the investigation was closed.'

'But there was something the police didn't know.'

'In the hours after Peter's death,

his money was being spent by someone else.'

So the really curious thing about this is that

Peter Fasoli dies in a house fire,

he's found in the early hours of January the 7th.

The next day, his credit card

is used to buy a ticket from London to Rome.

(mouse clicking)

On January the 11th,

a man called Jason Marshall boards a flight using that ticket.

'But who was Jason Marshall,

and how had he got his hands on Peter's credit cards?'

This case was one of the most unusual that I've ever dealt with.

The true facts hadn't been exposed in the initial investigations.

The charred body of Peter Fasoli

had been found in his house in Northolt, West London.

An inquest in August 2013 had concluded that it was an accident,

caused by a faulty light bulb, and the case was closed.

'But the body still had secrets to tell,

and the truth of what happened was yet to be discovered.'

Four days after Peter Fasoli died in a house fire,

a man called Jason Marshall boarded a flight to Rome

from Gatwick Airport.

He'd used a credit card in the name of Peter Fasoli to buy the flight,

and he also had cash

that he'd withdrawn from that account as well.

(mysterious music)

(Richard) 'Not long after arriving in Italy,

Jason started using online dating apps to find gay men.'

So within days of touching down in Rome,

Jason Marshall is busy setting up new connections online.

Jason had set himself up on dating websites,

and arranged to meet older gay guys,

and arranged to meet them

through these dating websites for sexual encounters.

He meets a guy called Vincenzo Iale.

'67-year-old Vincenzo Iale worked as a tour guide in Rome...'

'...and lived in a small town

outside the city called Torvaianica Alta.'

'Just over two weeks after arriving in Rome,

Jason was on his way to Vincenzo's house.'

(sombre music)

'Vincenzo may have been expecting a sexual encounter,

but Jason had something else in mind.'

Jason was not interested

in sexual meetings.

He just wanted to steal

their credit card or cash.

Every time, he was searching this kind of victim, and every time,

he approached to them for a sexual meeting,

every time with just one purpose.

Steal their credit cards, steal cash...

...extorting numbers and the bank details...

...and then killing his victims.

'Several days after his encounter with Jason Marshall,

Vincenzo Iale's body was discovered.'

Vincenzo was found completely nude,

er, on the floor, one week, seven days later, the homicide,

because he lived alone.

This murder scene was over a week old,

and in forensics, time is of the essence.

With the passage of time, vital clues such as the DNA of the killer

can be lost, and in terms of the injuries,

it can be harder and harder to determine which of the injuries

actually was the cause of death.

Decomposition will have started to set in on Vincenzo,

and it's usually first seen in the right lower abdomen

over the cecum and the appendix area of the body,

as a green discolouration of the skin

that gradually spreads over the entire body.

But the pathologist in this case

was well able to identify the numerous stab wounds

to the chest of Vincenzo.

And he could also see that he had been tortured,

and the crime scene show that he'd been dragged around the flat,

evidence of the physicality of the murderer.

Despite the severity of the injuries,

they were not what killed Vincenzo.

The pathologist found that Vincenzo had been strangled by a ligature,

and the mark on his neck was entirely consistent

with the use of an electrical cord.

Ligature strangulation causes pressure to the neck,

and the blood vessels and airways inside the neck.

It causes pressure to these red carotid arteries

that are taking blood up to the brain,

and it causes pressure on the jugular veins,

which are taking blood away,

and so the brain is starved of oxygen

when those blood vessels are pressed.

But it can also lead to compression of the airways

above and below the larynx, stopping air entering the lungs,

and so meaning there's loss of oxygen in the bloodstream itself.

Now the time it takes for someone to die with ligature strangulation

is very variable, depending on the ligature and the pressure applied.

It can be very quick,

or it can be delayed over a prolonged period of time,

depending how much pressure is applied.

(tense music)

'On the very day Vincenzo was found murdered,

Jason Marshall was on his way to meet his next victim.'

Within days, he moves on to another guy.

This time a chap called Umberto Gismondi,

who lives in Rome.

He met him on a social network site for sexual meetings.

The victim invited Jason in his home,

and then they had dinner together.

They go to the bedroom.

Jason not seem so interested

to have a sexual meeting.

'Armed with a truncheon,

Jason launched a terrifying attack on Umberto Gismondi.'

'First, he incapacitated his victim with pepper spray,

then bound and gagged him,

and attempted to suffocate him with a cushion.'

'And he made it clear to Umberto that this was not the first time

he had carried out such an attack.'

Jason showed a picture on his phone

and said to the victim, "Watch this picture."

"Watch this man. I killed him one month ago."

"If you don't give me the PIN number

of your credit cards,

I'll kill you too."

It is in effect whereby people

become more desensitised as time goes on,

and if they commit one harmful act...

...maybe it's easier for them to commit another one and another one,

and then maybe they realise that

they're actually kind of enjoying this.

And that... that keeps them going.

(sombre music)

Jason was a serial killer

because every time he made the same actions.

First of all, victims are the same,

homosexual, alone,

and they're old men.

Why old men?

Because Jason is a strong,

young, tall, powerful man,

and so in case of struggle, he could win against them.

Very fortunately, the victim's neighbours hear the commotion

and raise the alarm, and Mr Gismondi is rescued.

(siren wailing)

'Umberto Gismondi was very lucky to have been saved,

and he survived.'

'Jason fled the scene,

but Italian police tracked his movements using his phone,

and he was apprehended on a bus a few hours after the attack.'

'He was arrested and taken to a jail in Rome,

where he was provided with a defence lawyer.'

I was the court-appointed lawyer.

In my life, I will not have a case so bizarre.

I met Jason for the first time when he was in jail.

He said, "I am innocent, Francesco, I am innocent."

Jason was very convinced, and Jason was very believable,

and I thought, "Oh, maybe he's really innocent,"

but what he said to me

was not supported by the facts.

'When Jason had been arrested, he had fresh blood on him,

and he had credit cards and a gate key of his first Italian victim,

Vincenzo Iale.'

'He was also found in possession of pepper spray, a fake pistol,

and a counterfeit badge from the British embassy.'

Jason said to me, "I work for the British Embassy."

"I work for MI5." But, yeah, it was unbelievable.

Er, it was not, er, not credible.

'In 2014, Jason Marshall stood trial in Italy

for the attempted murder of Umberto Gismondi,

and the murder of Vincenzo Iale.'

During the final part of the hearing,

Jason wanted to speak,

and I remember that Jason said to the judge,

"You can't judge me because only God can judge me."

'In July 2014, he was found guilty

and sentenced to 16 years in prison.'

'Now he was confined to an Italian prison cell,

Jason Marshall could not kill again.'

'But the question being asked was, had he killed before?'

'Shocking evidence was about to come to light.'

This case is back to front, really, in that the suspect was locked up

for murder before we even knew there was a murder.

I've investigated many cases which have strange aspects to them,

but very rarely do you find a murder set to music.

(Richard) 'On the 6th of January, 2013,

58-year-old Peter Fasoli

had met a man called Gabriel on the Internet,

and invited him back to his home in West London.'

'But later that night, his house was on fire and Peter was found dead.'

And inquest concluded that it was an accident

caused by a faulty light bulb, and the case was closed.

The body had revealed Peter was alive during the fire,

but there was more to tell.

An all-seeing witness was waiting, ready to reveal a shocking secret.

There is an investigation,

and it does confirm that Peter's death was an accident.

So, you know, the family were obviously shocked and grieving,

but since it was just a tragic accident,

they move on with their lives.

Peter Fasoli's family are not particularly local.

His belongings, what's left of them,

what's not been, you know, completely destroyed

by the fire in his house, they're collected up

and they're stored by a friend of the family up in Yorkshire.

'It was not until almost two years

after his death that evidence emerged

revealing the truth of what really happened that night.'

Peter Fasoli's nephew decides that he would be quite interested

in going through some of Peter's effects,

which had been stored up in Yorkshire.

So, he goes to have a look.

He's particularly interested because he knows

that Peter had a shared interest with him in his family tree.

So, he thinks that there might be something on the computer

that Peter had in his house that might give him

a bit more information about the family history.

So, he goes to Yorkshire and collects the hard drive

from the computer and takes it home with him,

and sets it up so he can kind of have a look

and see what's on there.

(ominous music)

What he finds is not anything to do with the family tree.

He makes a very shocking discovery, erm, of a series of videos

that Peter Fasoli had made, initially meeting guys for sex

and it had been filmed on his webcam.

'But what he sees on the final video shows something else entirely.'

'Shocked by what he had discovered,

Peter's nephew immediately handed the video to the local police.'

We received a call from West Yorkshire Police

with some significant information

that was going to take the whole case into a new direction.

So, once we got back to London and reviewed the video

that Peter's nephew had found,

it was really shocking and quite a harrowing watch, to be honest.

It happened that Peter had a kind of hidden CCTV camera

that was connected to his laptop.

It was effectively a recording of the events of the evening

of his uncle's death,

and showed that Peter had been visited by another male.

(tense music)

The man in the video is wearing clothing that clearly intending

to portray himself as plain-clothes law enforcement of some description.

Jeans, bomber jacket, T-shirt under that.

When he takes the jacket off at times,

you can see that he's got a holster

with whether it's handcuffs in one slot, pretends to have a firearm.

There's a radio clip.

And if you were left in any doubt at that point,

he's also wearing an ID badge on a chain around his neck,

clearly intending to portray himself as law enforcement.

And the events ran on for several hours,

but for the vast majority of the time, entirely consensual.

There had been different role plays with the suspect,

role-playing either a police officer or an agent

or a spy or whatever was going through his mind,

but was certainly asserting

a position of power and authority over Peter,

who was quite willingly submissive to that power and authority.

(eerie music)

It was like a role play taken to extremes.

There was a role, certainly, and it was a powerful role.

A dominating role.

A role that had authority

and also access to specialised procedures and equipment.

But the play part of role play,

play itself,

can serve a function even for adults.

It can give them a taste of that identity that they're aspiring to.

Whilst they're acting out this role, life might seem different,

the situation might seem different

to how they are in their usual everyday life as themselves.

'But as the hours passed, something changed.'

It was only right at the very end

when things took a more sinister turn.

The young man in the video starts becoming quite violent.

He threatens him with a knife repeatedly.

He also injects him with a needle, more than once.

He really, really becomes quite violent and aggressive,

and he's clearly enjoying it.

He's clearly taking some sadistic pleasure

in bringing Peter Fasoli down so low and humiliating him.

Jason Marshall was calm and collected throughout.

There didn't seem to be any agitation, any panic.

It's as if he kept on playing the role.

And there's a point in the video

that I remember quite clearly actually

where it seems like the penny drops,

and Peter, going from being quite excited and energised

about this kind of role play,

it suddenly dawns on him.

It's not a game for him any more,

and he actually becomes very frightened, for real.

'Eventually, the torture escalated to a point of no return.'

The suspect took a roll of cling film

and wrapped it round Peter's head,

causing him to struggle to breathe and suffocate,

and then put a plastic bag over his head,

causing Peter to fall to the floor.

'Without realising it, Peter Fasoli had recorded his own brutal murder.'

This is a video showing Peter Fasoli's death

at the hands of an extremely violent, sadistic killer.

The cuffs were removed, the bag and the cling film were removed.

Shortly after that, the video then shows the suspect

clearing up the scene behind him, and then the video is cut,

but the sound continues.

And what can be heard is the sound of probably some accelerant

being poured around the flat...

and the sound of that being ignited.

And it's within seconds of those sounds

that you then hear the smoke alarm, which alerted the neighbours,

who subsequently as we know, called the fire brigade.

Throughout the video of Peter Fasoli's torture

and ultimate death,

there is a sort of weird situation

because he put on Classic FM in the background,

you know, for this, erm... encounter.

I wouldn't say romantic particularly,

but it's an... it's an encounter of sorts with Jason Marshall.

And it is very bizarre, because you hear Myleene Klass

talking about classical music in the background,

and that is on

throughout this horrendous, violent situation

that's unfolding in his house.

The detail of this, er, remains with me today.

It was unbelievably shocking.

It was showing such determination,

such calculation, planning, evil almost.

And seldom do you see in a domestic context,

er, footage of someone's death

through evil crime.

'The truth of what happened that night

had been hidden in Peter's body all along,

waiting to reveal itself,

but the body had never been asked.'

A body may never lie, but sometimes it's really important

to make sure that you ask the right questions.

We know that Peter was still fighting for his life

after Jason had set fire to his house,

and the initial cause of death was inhalation of fire fumes

in association with his heart complaint.

But the major contributing factor to Peter's death,

despite all he'd endured, was clearly suffocation.

And suffocation occurs when the external air passages,

the mouth and the nose, are blocked, so that air can't enter the body,

and that will deprive the body of oxygen,

and eventually result in brain death,

and the death of the individual.

And we know from the video that Peter was struggling

and fighting to breathe,

and we also know that the cling film was removed and replaced

several times.

But when the fire was burning, Peter was still alive

and struggling to breathe,

which accounts for the soot that was present in his airway

at the time of the first post-mortem examination.

And it's clear that wrapping cling film around Peter's head by Jason

was intended to kill or at least cause serious harm.

What had been thought to have been an accidental death

as a result of a house fire

had now turned into something much more significant.

It was now a homicide investigation.

(Richard) 'In January 2013,

Peter Fasoli invited a man calling himself Gabriel

to his home, after they had met on a dating website.'

'The next morning, Peter was found dead after his house caught fire.'

(smoke alarm beeping)

'Almost two years after his death, shocking footage was discovered

that revealed he had in fact been tortured and murdered.'

'But although detectives had the footage,

they still had to identify the man responsible.'

What really goes through your mind then

is that you have an absolute passion

to do the right thing for the family.

The whole point of doing my job is to find answers for the family,

and what becomes an absolute priority and a real motivation piece

is to identify who the suspect is

and prevent him causing any more harm to anybody else.

'But just who was this sadistic Internet predator?'

They had an image of this person

who had been with Peter Fasoli on the night of his death.

They had him on the video,

but obviously at that stage, they didn't know who he was.

They then have to follow this trail of evidence

and try and find out who the person is,

who's clearly, you know, been extremely violent.

(tense music)

First thing that we had to do was look through all of the video

to try and identify any clues

or anything that would help us with the identity of this suspect.

So that involved hours of going through, minute by minute,

almost frame by frame at times

in terms of what had happened in the house.

Is there any tell-tale signs that the suspect is giving out?

Is there anything that he says, any information, any use of names?

Anything like that.

At one point during the evening,

the suspect had demanded Peter's credit card,

had demanded the PIN number for his bank card,

er, and had gone away from the house

for a period of time and then returned.

This opened up the consideration

that the murder was financially motivated.

When we looked at his finances in more detail,

what we identified was that the days following his death,

his bank details were used to purchase some flights

from an airline, and then enquiries with that airline

identified who had bought the tickets

and in what name those tickets had been purchased.

We established from the airline that the account had been used

to buy tickets to Italy in the name of Jason Marshall.

'So, the man Peter had met who called himself Gabriel

was in fact Jason Marshall.'

'Jason was already known to the Italian police,

but not to the UK detectives.'

'A quick searched revealed that Jason Marshall

had spent most of his life on the wrong side of the law.'

And when we did some police background checks,

it was found that he was known to police

for impersonating a police officer.

So when you look back at the investigation

and what we'd gathered so far, the whole evening involved role play

and role-playing law enforcement,

and here we've identified the name of a suspect

who's got convictions for the same thing.

They'll be some people who feel the need or desire to dress up

and pretend to be a policeman or an ambulance man or a fireman,

but they don't go along and kill somebody, playing out that role.

You can probably fairly describe Jason Marshall

as a lifelong fantasist.

You know, his life is to a certain extent a bit of a mystery.

He claims that his parents were both drug addicts

and he grew up in East London.

His obsession with living a fantasy

really comes from his desire

to block out the harsh realities of life,

and also give him the kind of status that he's craved,

and that's really where his obsession with police officers

and anyone in a uniform comes from.

Because he puts on a uniform, he becomes a different person,

and the kind of person that people respect.

But in reality, his life is quite a sad one.

He makes money as a male escort.

He becomes increasingly unhappy, and he's taking out his anger

and frustration on these older guys

that he's meeting for sexual encounters,

and there comes a point

where he moves down a very, very dark path.

And that's really the point at which, unfortunately,

his life collides with Peter Fasoli's.

'Jason Marshall's online profile on dating apps

gave a chilling clue to his state of mind.'

'When he had met up with Peter Fasoli the night before he died,

Jason had used the online name Gabriel.'

He imagined that he was the archangel Gabriel,

and he's creating this online persona.

I mean, a lot of people don't use their own names on dating websites,

that's not unusual,

but the fact that

not only has he created this online persona,

he carries it over into real life

and carries it over into this very different and extreme character

that he's created.

So, he goes from a position where he's less powerful,

he's working as a male escort,

but because he's created this complete alter-ego

where he is in charge

and he is the one with the handcuffs and the police radio

and making the arrests, and he is a big man,

he's turning the tables on people

who want him for his, you know, for his services.

'Having identified Jason Marshall,

police now had to bring him to justice.'

(Matt) The next challenge really was, where is Jason Marshall now,

and some fairly quick research using the Internet,

and identified, to my horror,

that Jason Marshall was in Italy serving a custodial sentence,

having killed a male over there

in the weeks that followed the death of Peter Fasoli.

It was a moment really where I had to temper my kind of enthusiasm

and joy that we'd identified who this person was

and we were going to make some progress

with a real kind of sombre moment of reflection

in terms of, had there been opportunities missed?

What if things had been done differently?

What was the consequences of the delay in identifying this offence?

But it was never lost on me in those kind of early moments,

the kind of "what if" questions around those victims in Italy.

'The video of Peter's murder shed light

on the murder of Vincenzo Iale in Italy.'

People are murdered in all sorts of different ways,

and some crime scenes are really horrific.

The pathologist found that Vincenzo had been strangled by a ligature,

and in fact the crime scene showed

that Vincenzo had been dragged around the flat,

evidence of the physicality of the murderer.

'But in Peter's case, the fire had changed everything.'

A fire means that a lot of valuable evidence will have been lost,

and there was evidence that he'd been tortured.

The burning of the body had obscured any evidence of bruising

or the injection sites, which made them much harder to see,

and there was no evidence of suspicion.

And it's not possible to determine if death occurred deliberately

or by accident.

'But now the evidence proved without a shadow of a doubt

that something very sinister had happened.'

'After four and a half years,

Jason Marshall would finally face justice

for the brutal murder of Peter Fasoli.'

It was early 2017

when Jason Marshall was finally extradited back to the UK.

He was met by my officers and arrested on UK soil,

and at that point, the prosecution for the murder of Peter Fasoli

started in earnest, really,

and led to the subsequent trial.

And that's probably the first time that there's a real sense

that we're now starting to deliver justice for Peter's family.

Jason has to answer for his actions, and in a UK court,

and he can't hide behind the Italian prison cell bars any more.

(tense music)

'In July 2017,

Jason Marshall finally stood trial in London.'

It was an extraordinary trial at the Old Bailey.

Extraordinary because of the material, the evidence.

I've done many serious cases,

but I have never seen footage

showing the crime in such a calculated, cold, powerful way.

Erm, I've never come across that before.

It was very disturbing,

and it must have been very disturbing for the jury.

'In court, Jason Marshall claimed he had amnesia,

and couldn't remember anything from that night.'

The purpose of the cross-examination was to show that his amnesia,

as he claimed, was a lie.

And there was quite a bit of material,

such as what he did afterwards.

When he sent a text to Peter's phone,

the text message is so obviously purposeful

and thinking and calculated,

and is not consistent with amnesia of an event at all,

leaving aside what he then went to do,

getting himself to Italy and killing one and trying to kill another.

His behaviour in the witness box was pretty strange, to say the least.

He'd run out of excuses, and he'd run out of stories.

And the fantasy was quickly unravelling,

and it just didn't hold.

It just didn't hold for him any more,

so there was nowhere for him to go.

'The evidence on the video was damning.'

Having this piece of footage meant

that Jason Marshall couldn't deny that he was there.

He couldn't deny what had happened,

and it would have made it extremely hard for him to wriggle out of it,

because it's all there.

You know, you only have to watch what he did to realise

that this was an extremely sadistic and cruel act of violence

against a defenceless man.

Marshall is an extremely dangerous man.

I think he knew what he was doing, wanted to do it. He wanted to kill.

He never expressed any true remorse at all.

He was determined to do what he did, and he did it again,

and he did it again,

and I don't think he's someone who is capable of remorse.

One of the most important things at this moment of course

is to get back in touch with Peter's family,

explain what we'd found and explain the process we'd made

at every single stage of the investigation.

It's critical to me, and I think it's really important

that, erm, the family understand what's happening.

Ultimately, that's what I'm there for.

It's to find the answers that the family are looking for,

and if I can find a way to keep them up to speed and up to date

with the investigation and the process that we're making,

then that's really, really important.

'The jury took just 75 minutes to reach a unanimous verdict,

and Jason Marshall was sentenced to life

with a minimum term of 39 years.'

He will spend pretty much the rest of his life in prison.

He tortured Peter Fasoli

for several hours before killing him,

and that made it an even more serious murder.

He took sadistic pleasure in it,

and after he was caught, he showed absolutely no remorse.

Serial killer Jason Marshall clearly had the intent to kill,

and if it hadn't been for the discovery of that video,

we'd never have known how Peter Fasoli met his tragic end.

'In the end, the answers were hidden in Peter's body all along,

but no-one had asked the right questions.'

We must always be highly suspicious in the autopsy room,

and make sure we find the cause of death,

not just a cause of death.
