All language subtitles for The Truth About My Murder S01E02 1080p WEB DL H264 BTN_track3_[eng]

(man) '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,
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)

(phone line ringing)

(woman) 'Hertfordshire Police.
How can I help?'

(man) 'My partner
has been missing since Monday

and not contacted anyone,

so we just decided
we should report it.'

'What's your partner's name?'
'Helen Bailey.'

Royston in Hertfordshire
is not the place

where well-heeled women
in their 50s vanish.

'So, it was a surprise when Helen
Bailey, a renowned children's
author,

was reported missing from home.'

She'd last been seen walking her dog
on t11th April, 2016.

'But why would someone
who seemingly had it all'

and who was planning her own
wedding, suddenly disappear?

'Could I take your name, please?'
'Ian Stewart.'

'We'll be in contact shortly, OK?'
'OK, thank you.'

People that knew Helen Bailey,
her family and friends,

describe her as this very warm,
very kind person,

but also someone
who was very witty, very funny,

with a wicked sense of humour.

There we go, ready?

(man) 'She was a hugely successful
author of teenage fiction.'

The neighbours where she lived
said she was friendly, very open.

Invited everybody round for
coffee and cake when she moved in.

Very down to earth.

There he is.
You can see that he does exist.

Oh! Ha!
That wasn't supposed to happen!

(Richard) 'But Helen had been
through terrible heartbreak.

Her marriage of 15 years to
John Sinfield had ended in tragedy.'

Helen's husband, John,
died very suddenly.

He drowned whilst they were
on holiday in Barbados in 2011.

(Sam) 'He was in the sea.'

She heard him calling for help.

She saw him disappear under
the waves and he sadly drowned.

It must have been horrendous
for her to go through that.

Almost unimaginable.

Helen started a blog online
called Planet Grief.

'She talked about
the kind of the difficulty

of dealing
with really everyday things,'

like buying a single Scotch egg
in the supermarket

or taking out the bins on your own,
week after week,

and how lonely that made her feel.

Writing the blog was
dealing with her grief

and reaching out to other people
going through the same thing.

She was able to turn
her own experiences of grief

into something funny

and something that other people
could take great comfort in.

That was because
of the kind of natural warmth

'that Helen Bailey had.'

Real life after death is
far more bizarre, more complicated,

and quite frankly bonkers
than any fiction plot

'that I could come up with.

'For many of us, this reflecting
on our relationships'

is part of the process
of bereavement.

(Richard)
'Then, in October that year,

eight months
after her husband's death,

Helen met someone
through an online support group.

He was a widower
by the name of Ian Stewart.'

Helen met Ian online.

They were both part
of a bereavement group

and that's how they came
to know each other.

So, he himself was widowed in 2010.

He had two sons, at that time,
would have been teenagers.

So shared experience with Helen
Bailey, both of them widowers.

They'd have had
a lot to talk about.

I introduce you to my new book,

which is called When Bad Things
Happen In Good Bikinis,

subtitled Life After Death
And A Dog Called Boris.

Helen spoke about meeting Ian
in her blog

and also in her book.

She referred to him
as her gorgeous grey-haired widower.

'At the end of her book,

she talks about having found her
happy ending with him.'

(Richard) 'The fact they've both
lost a spouse seemed to draw Helen
to Ian.

Before long,
they moved into a house together

in the Hertfordshire countryside.'

Helen Bailey and Ian Stewart

bought a very large house together
in Royston in Hertfordshire.

It was worth £1.5 million,
decent amount of land around it

'and Ian Stewart's two sons
moved in with them as well.'

(Richard) 'After four years
together, they were planning their
wedding.

But then on 11th April, 2016,

Helen suddenly
and inexplicably disappeared.'

Helen had been googling
wedding venues

because Ian and Helen
were planning to get married.

'All of the people that knew Helen

said it was completely out of
character for her to disappear.'

Her friends and family
were becoming very concerned.

They'd said they couldn't
get in touch with her

and at that point
Ian reported her missing to police.

(phone line ringing)

(woman) 'Hertfordshire Police.
How can I help?'

'My partner has been missing
since Monday,

and not contacted anyone, so we
just decided we should report it.'

'What's your partner's name?'
'Helen Bailey.'

'Did she say anything unusual?'

'Nothing before I went out, no.

She asked me to run an errand
after I had been to the doctors.'

In the 999 call,
given that this is four days

after he's last seen his fiancee,

he sounds incredibly calm,
almost to the point of nonchalant.

'What's her height?'

'Oh, I'm going to guess it.
She has told me. Probably 5' 10".'

'And her eye colour?'

'How do you forget these things?'

He's almost making light
of the situation.

I think he says he can't remember
the colour of her eyes.

It doesn't come across as a man
whose fiancee is missing,

'who knows
what has happened to her.'

'And what sort of build?'
'Slim.'

'She's is slim.'

'That's easy.'
(chuckles)

'She left a note.

She said something like,
"I need space and time alone.

I'm going to Broadstairs."

'In Broadstairs,
we've got a cottage down there.'

Ian maintained
that she had left a note

saying she wanted
some time to herself,

and that he shouldn't contact her.

(Richard) 'Ian Stewart's account

that Helen had gone
to her holiday cottage in Kent

didn't necessarily ring alarm
bells.'

(Chloe) 'Her dog, Boris,
had gone missing too,'

and that was
a perplexing part of the puzzle,

and played in to the idea
that she had gone off somewhere

with her dog for time on her own

because why would the dog
also be missing?

She's got her mobile phone,
she's a got vehicle,

she's got a whole array
of support around her.

Could she have gone away
for a short time on her own?

The answer is yes.

'Would she be happy going up to
someone and asking for directions?'

'Yes, she's very good
at talking to people.'

However, she would be leaving
a foot print.

She'd be leaving a footprint
by the movement of her vehicle,

her mobile phone,
a contact on a computer.

If she'd gone on the Tube
or a flight out of the country,

she would be recording
a bank transaction:

buying a coffee,
getting tickets or whatever.

But there was no transactions
by Helen on her bank account.

'Leave that with us. We'll be
in contact with you shortly, OK?'

'OK. Thank you.'
'No problem. Thank you.'

'OK, bye-bye.'
'Bye-bye.'

(Richard) 'With no sign of Helen
a week after reported missing,

officers from Hertfordshire Police
Major Crime Team

interviewed Ian at the house.'

That's where an investigation
would start,

with a person
who'd last seen them alive.

The time, the place, the location.

It's at this point where things
start to begin to build up.

'Ian Stewart was not supportive.
He was not helping in any way.'

So, that's where the concerns
first start to begin to surface.

The note, allegedly made by Helen,
could not be found.

That would be a vital clue
as to what's happened to her,

but it couldn't be found.

Police had searched
the property at the time.

Didn't find her. Didn't find
where she'd gone. Unexplained.

(Richard) 'For three months,
no sign of Helen.

No one had seen or heard from her,
and no answer on her phone.'

Even bizarrely, he went away
on a holiday for two weeks to Spain,

whilst all this is going on.

Now, is that the actions of someone
who really cared for his partner?

Is that the actions
of an innocent man? Don't know.

(Richard) 'With no leads,
police went back to the house again.

This time
with a specialist search team.'

Three months down the line,
a neighbour has tipped off officers

that there's a cesspit at the house.

(Richard) 'The first time
police had searched,

Helen's Jeep had been parked on top
of the entrance to the cesspit.

But this time the car had been moved

and in amongst the human waste,
police made a grim discovery.'

Police found Helen's body
hidden in human excrement

in the septic tank
beneath the garage at her house.

But she was not alone in that pit.

With her was her beloved dog
and a pillow case.

After three months
in those conditions,

decomposition can be well advanced.

It affects first the skin.

The skin begins to become sodden
and soggy and to fall off.

Eventually, the underlying muscles
are affected, too,

and that can make a postmortem
examination really quite difficult.

It can eventually result
in skeletonization of the whole
body.

In this case, decomposition
had progressed to the point

where the Home Office pathologist
couldn't be sure

whether Helen was alive or dead
when she entered the septic tank.

But what he could say with certainty

was that she didn't get there
through natural causes.

(Andy) 'There's no way
she climbed in there on her own.

Someone has put her in there.'

She was murdered, brutally.

(Richard) 'On 15th July, 2016,

police found the body of the missing
children's author Helen Bailey,

in the septic tank
beneath the garage of her house.

The entrance
had been hidden under a car

and was only discovered
after a tip-off from a neighbour

three months
after Helen went missing.'

Dealing with
the actual recovery of the body,

that would have taken
a number of days.

It would need careful extraction
of the fluid

from inside the septic tank,

and then excavation in and around
the actual tank itself,

and then people going into that tank
and removing the body.

No matter how many murders
you've dealt with,

to deal with that
would be horrendous.

The body was showing evidence
of significant decomposition,

after a period of about three months

immersed in this excrement.

A postmortem in that condition
can be extremely difficult.

What's surprising
is that some significant organs,

like the colon
and sometimes skeletal muscle

can be so well preserved,
they can be thoroughly examined.

'The secret of what had happened
to her was still hidden in her body.

But how she had ended up in there
had to be answered.

Her fiance, Ian Stewart,
was the last person to see her.'

(woman) 'When was the last time
you saw her?'

'Monday afternoon,
before I went out,

about quarter to three,
twenty to three.'

'She's definitely not at home, no?'

'No.
I've literally checked everywhere.

We have got quite a large house, but
I've literally checked everywhere.'

In the early stage,

he's a person of interest,
as opposed to a suspect.

You're going in
with an absolute open mind.

You're trying to find information

and ask questions about
her movements, his movements,

in an effort to find out
what's happened to her.

(Richard) 'Police examined
hours of CCTV footage

and tracked Ian's movements
from the day Helen went missing,

when Ian was seen
getting rid of items

that included
what looked like a duvet.'

Your fiancee is missing
and you're at the local tip.

Why would it happen to be the same
day that she was last seen alive?

(Richard) 'They then started
taking a closer look

at the couple's finances.'

Helen was a very successful
children's author.

She was wealthy in her own right.

Ian's sons always said that money,
as far as they knew,

had never been an issue
for their dad either.

(Richard) 'Helen had recently
changed her will,

making Ian her main beneficiary.'

Ian didn't work himself

and Helen was concerned
that if anything happened to her,

he wouldn't have means
to support himself.

She made him the sole beneficiary
to her estate,

which is in excess of £3 million.

There was also
a huge life insurance payment

that he would be in receipt of,
should she die.

(Chloe) 'On the day Helen
went missing, 11th April,'

Ian Stewart logged on
to her bank account

and changed a standing order

'going from her bank account
to their joint account,'

from £600 to £4,000.

(Richard) 'But despite
this suspicious activity,

it was only when he body
was recovered from the cesspit

and samples were sent
for toxicological analysis,

that it revealed the truth
about her death.'

Not much of Helen's body
remained after three months,

but the toxicologists
were able to identify zopiclone.

Zopiclone is a powerful sedative.

It's only available on prescription

and it's usually used
to treat insomnia.

This was present in samples taken
by the pathologist at the autopsy

from the colon, which is the large
bowel sitting in the abdomen.

Also from muscles
present in her thigh

on the front of the upper leg.

Also present was Helen's hair.

Hair is made of keratin,
the same chemical

that's used to make
fingernails and toenails.

It's incredibly resistant
to decomposition.

Hair can also be
the pathologist's friend

because we know how fast it grows.

About a centimetre per month
in life.

And in to the hair is incorporated,

all the drugs and chemicals
present in the body.

So, it can act
as a record and a timeline

for things circulating in the blood.

And the toxicologists report showed

'that Helen had been exposed
to zopiclone

for several months
prior to her death,

and at increasing concentrations.

Now, Helen didn't have a
prescription for the drug zopiclone,

but someone else did.

'Ian Stewart.'

In the weeks before, Helen had done
some research on her computer

to research the effects of
just feeling drowsy, feeling tired,

'feeling that she needed sleep
during the day.'

What is clear in this case,

Ian Stewart had been administering
this strong sedative

for several weeks, if not months,
leading up to this murder.

(Richard) 'Police also recovered
a pillow case from the septic tank,

suspecting Ian Stewart
had used it to suffocate Helen

before dumping her body.'

(Richard) 'Ian Stewart was arrested
and his true nature came to light.'

Ian Stewart is one of the clearest,

most unequivocal examples
of a psychopath

that I think
I have ever come across.

He is prepared to do anything

to accomplish the ends
that he seeks.

The definition of a psychopath.

(Donna) 'What's intriguing
about Ian Stewart'

is that I think the potential
to carry out these kinds of crimes

was always there,

but his upbringing,
his social circumstances

were such that it was
just never necessary.

But the potential,
make no mistakes, was always there.

He led the police down
the garden path for three months,

watching them conduct a completely
futile search for Helen Bailey,

whilst knowing that he had
put her body in the cesspit

underneath their garage.

There is no emotion to this man.

So, all he is,

is calculation,
strategy, manipulation

to get what he wants.

There's no calibration
for the impact on others.

'Everything is done on an
intellectual and strategic basis.'

(Richard) 'Ian was charged
with the murder of Helen Bailey.

At his trial in January, 2017,

he came up with a bizarre story
to explain her death.'

What he told us in court

was that two men called Joe and Nick

had come to the house
on the day Helen had disappeared,

and said that they were business
associates of her late-husband John.

And the story spiralled from there.

He said he saw them several times,
they would come to the house,

they would threaten him,
physically attack him,

and that they gave him a phone
to contact them on,

and that ultimately it was them
that murdered Helen,

and them that put her body
in the cesspit.

There were gasps
from the public gallery,

as he spoke about this in court.

(Richard)
'The jury didn't believe him.

After a trial lasting six weeks,

they returned their unanimous
verdict after just six hours of
deliberation.

In February 2017, Ian Stewart
was found guilty of murder

and was given a life sentence
with a minimum term of 34 years.'

(man) 'A very challenging enquiry.'

The lies and deceit
that Mr Stewart offered

during our investigation
really did hamper us.

It was difficult to understand
Ian Stewart's motivations.

He and Helen Bailey seemed
to have a happy life together.

They had a big house.
They didn't seem short of anything.

She was planning their wedding.
They were going to get married.

He was busy planning her murder.

It was hard to understand what more
he could have wanted from life.

The judge said that it was
a financially motivated murder.

He did it for money.

You think how callous
that he's killed his fiancee.

'He's put her in a cesspit.'

Unimaginable
how somebody could do that.

(Richard) 'When Ian Stewart's first
wife, Diane Stewart, died in 2010,

no one suspected foul play.'

But after he'd been convicted
of the murder of Helen Bailey,

police decided to reinvestigate
the circumstances of Diane's death.

This is, without doubt,
the most extraordinary case

I've worked on as a news reporter.

(Sam) 'In the interviews,
he answers a couple of questions'

and then he's completely silent
and shakes his head.

Had he not gone on
to murder Helen Bailey,

I don't see why
we would have found out the truth

about what happened
to Diane Stewart.

(Richard) 'When Helen Bailey

was found in the septic tank
at her home,

the court concluded Ian Stewart
had drugged and suffocated her

to gain her wealth.

'But Stewart's first wife, Diane,
had also died young.'

And when the police realised

that Diane had been married
to a convicted murderer,

they decided
to start a new investigation

into the circumstances of her death.

'Six and a half years
after her death,

could Diane's body still reveal
the secrets of how she had died?'

Diane Stewart is loved by everybody.

The kind of person
that people would be visiting.

'She had a wide circle of friends.

She worked
at the local primary school.'

She loved being part
of the local community.

Ian and Diane lived
in a leafy Cambridge village

with their two sons.

The neighbours
I have spoken to told me

that they seemed like
a happy family.

Very quiet.
Diane was a very lovely person.

No reason to think anything strange
was going on.

Very proud of their two sons.

They were able to do the things
that they enjoyed.

All that changed when Ian Stewart

made a 999 call
to the ambulance control.

(phone line ringing)

(woman) 'Tell me what's happened.'

'My wife's had a fit.
She's in the garden.'

'You need to slow down, OK?'

'She's in the garden.
She's unconscious.'

'OK. Are you with the patient now?'

'I'm just going out.'

'Can you see her
from where you are?'

Ian's account was
that he'd been to the supermarket

to get some things
for his eldest son

'who was having a driving test.

Hopefully,
they'd be celebrating good news.

They were going
to have a celebratory lunch.'

'Is she awake?'
'No, no, she's not awake.'

'Is she breathing?'
'No. I don't think so, no.'

'Check on her, sir, for me, please.'

He says he got to the supermarket.
Hadn't got his wallet.

He had to come back home
and there he found his wife, Diane,

unresponsive, on the ground.

'I've tried and get her in recovery
position, but she just flopped back.

I think she's had a fit.'

'You think she's had a fit?'
'She does have epilepsy.'

'Just bear with me a moment.'

At that time he said
that she suffered from epilepsy

and that he believed
that she'd had an epileptic fit.

(Chloe)
'He tried to resuscitate her.'

When that didn't work,
he went over the road

to try and raise the neighbour,
a doctor,

but when he got no response,

he came back and again tried
to do CPR on his wife,

before eventually dialling 999.

(woman) 'We need to help her.

I'll tell you exactly
what to do next.

Pump the chest hard
and fast at least twice per second.'

He was then told
by the operator to conduct CPR.

'You need to start this, sir, OK?'
'I've been doing that.'

'Count out loud,
so I can count with you.'

'OK. One, two, three,
four, five, six...'

'That's it. Well done.'
'Seven, eight. One, two...'

This went on
for about nearly half an hour

before paramedics and the air
ambulance arrived at the scene.

'One, two, three...'

'Has he stopped?
Have they seen you?

Right, OK, you keep doing what
you're doing until they're ready.'

Unfortunately,
when they arrived at the scene,

there was no sign of life
and Diane was pronounced dead.

(Richard) 'Ian told everyone
that Diane had died

after having an epileptic fit.

But only Diane's body could reveal
what had happened to her.'

Epilepsy occurs when there is
uncontrolled activity in the brain

and the brain is
the central controlling system

for the nerves
through the arms and the legs

and the abdomen and the chest.

When the brain has an epileptic
event that control is lost.

There's a total random discharge,

often resulting
in unconsciousness and collapse

and sometimes even resulting
in sudden death.

That sudden death
may on occasions be called SUDEP.

Sudden unexpected death in epilepsy.

About half-a-million people
have epilepsy in the UK,

but only about 600 die each year

and most of those suffer

from severe convulsive
regular epileptic fits.

'Diane didn't suffer
from fits like that.

Diane's death
was attributed to SUDEP,'

but, in fact, she hadn't had
an epileptic fit for decades.

She kept her epilepsy
very well controlled.

This doesn't completely rule out
SUDEP as a cause of her death,

but it does make it much less
likely.

(Andy) 'They were pushed away from
murder right from the beginning.'

The narrative was set by Ian Stewart

that she had suffered
an epileptic fit.

'This story
was being pushed and accepted'

and it was not challenged.

'Everybody has fallen for it.'

(Richard) 'Any forensic evidence
that may have proved otherwise

was destroyed at the crime scene
by the paramedics

trying to resuscitate her.'

The difficulty is the 999 call

gets put through
to the ambulance control.

The ambulance control have clearly

got to consider
the preservation of life

and that's what
their main priority was.

'From my perspective,
from an investigation perspective,

if a person has died,'

that person themselves becomes
a very important crime scene.

The contact, the DNA,
the blood distribution,

the movements of the body,
the movement of clothing.

All those are very, very important

to help identify what's happened
and identify who's done it.

How was that crime scene treated?

Or was it ever considered
a crime scene?

Probably not.

(Richard)
'Because there was no suspicion,

only a routine postmortem
was carried out

to determine the cause of death.'

A normal hospital
postmortem examination

is significantly different

to a Home Office
forensic postmortem,

which requires a much more detailed
examination of a crime scene,

examination externally of the body,

an examination internally
of the body.

Where every area of the body
is very minutely,

closely examined at forensic detail.

That's not carried out
at a hospital postmortem,

where it's more of a routine
looking for a cause of death.

'There is a cost

because a forensic postmortem
costs significantly more.'

Her cause of death was recorded

as being sudden death in epilepsy,
natural causes.

'You know, that's it, case closed.'

(Richard) 'Diane's body was
then released back to Ian Stewart,

who had her cremated.'

The truth is
he got away with murder.

(Richard)
'Six and a half years later,

with the case reopened,

Ian's behaviour
at the time of his wife's death

was called into question.

There were some concerns
about Ian's behaviour

after his wife death.

Some people talked
about seeing Ian at the funeral

and describing him as aloof.

Just distant.

Not coming across as a husband
whose wife had just died.

Ian Stewart received almost £100,000

both in a life insurance policy
and from bank accounts.

(Andy) 'He spent money
on an MG sports car.'

And that's not the attitude
that you would expect from someone

who's a grieving partner.

Why would he act in that way?

People think psychopaths are clever
and to some extent, they are.

They've learnt intellectually
how to carry out every role.

So, they're better
at carrying out those roles

than people who are doing it
from any emotional basis.

But what they're doing
doesn't come from any real place

and somewhere along the line
that always gives them away.

(Richard) 'Despite
all this suspicious behaviour

at the time of Diane's death,

no-one had questioned
Ian's account of what had happened.

But he had made
one very big mistake.'

(Sam) 'Diane was
a very public-spirited person.'

She had a donor card
when she died that was found.

She'd requested the parts of her
be left to medical science.

Among them were her brain.

He thought he'd covered his tracks.

The body was cremated,
but every contact leaves a trace

and that trace was left in her brain
that was still in storage.

'My wife's had a fit. She's
in the garden. She's unconscious.'

(woman) 'You think she's had a fit?'
'She does have epilepsy.'

'Is she breathing?
'I don't think so.'

'I turned get her in the recovery
position, but she just flops back.'

When Ian Stewart's first wife,
Diane, died in 2010,

no-one suspected foul play.

It was only after he'd been
convicted

of the murder of Helen Bailey

'that the police
decided to reinvestigate

the circumstances of Diane's death.

There was a part of her body
ready to tell the truth,

no matter how much Ian Stewart
had tried to cover his tracks.'

Diane's brain
was donated to medical science

and actually it was Ian
who allowed that to happen.

It'd been stored in the brain bank
over a period of six years.

The option would have been available
to refuse that,

but that potentially
could have aroused more suspicion.

So that wasn't a risk he would take.

(Richard) 'And Diane's brain
would hold the secret

that had been missed
during the first postmortem in
2010.'

A first pathologist
examined Diane's brain,

but found no evidence to suggest
she'd died from an epileptic fit.

However, a second pathologist
had looked at her brain

and found alterations.

He found evidence
that her brain had suffered

from a prolonged period of ischemia.

Ischemia is where the brain
is deprived of oxygen

for a prolonged period of time.

Oxygen gets to the brain,
as it does to all organs,

through entering the mouth and nose,

passing down into the lungs
through the trachea and the bronchi.

The oxygen's exchanged in the lungs
and gets into the blood stream,

goes to the heart,
pumped back up the arteries,

running up to the organs,
the arms and the legs.

That's how oxygen
gets to the brain.

And a blockage
in either the blood supply

or the entry of oxygen into the body
through the mouth and nose

can cause ischemic damage
to the brain.

Now you don't get ischemia
in a normal healthy breathing person

and you don't get ischemia
in an individual

who's just had an epileptic fit.

So, the pathologist in this case
came to the conclusion

that Diane
had been deprived of oxygen

for a period of between 35 minutes
and one hour

and that she had
in fact been suffocated.

Ian Stewart's might've thought
he'd gotten away with this,

but his secret was revealed,

only by the examination
of the brain,

which was absolutely crucial.

The body itself was the evidence
that convicted him.

(Donna) 'When arrested,
we see this apparent faux outrage.'

We see this indignation
at him being arrested.

Ian Stewart does not think like us.

There is a genuine reaction there,

but it's a reaction of irritation.

It's annoyance at somebody
stepping in his way.

(Sam) 'The first paramedic
to attend the scene

said there were signs of CPR
he'd expect to see if attempted.

He said ribs can pop, ribs can snap.

You'd expect to see some injuries.
None of which were present.

You've got the call handler
instructing you how to do CPR,

you're not seeing her
coming back to life,

you would be giving it
everything you'd got,

but the paramedics saw no signs
of injury to her body.

Both Helen Bailey and Diane Stewart
are vulnerable.

They have child-like qualities.

They're naive. They're trusting.

They are his ideal victims
and he will have had a sixth sense.

He will have been aware that they
did constitute his ideal victims,

in that they were so different
from him,

that in some ways they would
not have very readily recognised

the coldness, the calculatedness
at the heart of this man,

because it was just so different
from who they were.

(Richard) 'In 2019, while in prison
serving his life sentence

for the murder of Helen Bailey,

Ian Stewart was charged
with Diane's murder.

He denied it,
but in court the truth came out.'

So it was tense dynamic
in the court room

because of the stakes involved.

There's a man on trial
for the murder of his wife.

Their two sons
are in the witness box.

Diane's elder sister was there.

They'd all been witnesses
for the prosecution

and you're hearing
this horrible detail.

They're members of your family
that you're hearing about.

What an awful thing for them.

(Richard) 'On 9th February, 2022,

Ian Stewart was convicted
and given a whole life order.'

The essential part
of this second trial of Ian Stewart

was the first trial, the death
of his fiancee, Helen Bailey,

and the two cases
were put side by side,

so they could see the parallels.

In both cases, this was a person
in a relationship with Ian.

'In both cases,
they were home alone together.

In both cases,
their consciousness had been reduced

and they were then killed
potentially by smothering.'

(Richard) 'The critical evidence
was provided by Diane's body.

The analysis of her brain tissue
indicated her death

was likely to have been caused
by restriction to her breathing

from an outside source.'

Suffocation can be caused
in different ways.

Basically, it's blocking the mouth
and the nose with the hands

or using something soft,
like a pillow or a cushion.

Sometimes the individual
will fight back.

May be injuries to the arms
as they push against the assailant.

If the assailant sits on them,
there may be bruising to the chest.

But none of those injuries,
those defensive injuries,

will be present if the person
is sedated and unable to fight back.

'It had been established during
the trial for Helen Bailey's murder,

that she had been sedated
and suffocated.'

The fact that there was no evidence
in Diane Stewart's case

that she had suffered the same fate
wasn't lost on the jury.

(Sam) 'The jury were out
for under two days of deliberation,

in the second trial of Ian,

and they found him guilty
of the murder of Diane.

The second time guilty of murder.

He has been sentenced
to a whole life tariff,

which means he will
definitely die behind bars.

Whole-life tariffs

are not given out that often...

and it reflects
the severity of his crimes.

A whole-life order
is the most severe sentence

a judge can pass in a UK court.

The perpetrator will go to prison
and they will die in prison.

That's how grave,
how serious the whole-life order is.

(Sam) 'He's financially
very comfortable

and yet he's gone on
to murder his fiancee, Helen Bailey.

Why is it that he's done it?'

He doesn't need the money.
Is it greed? Something else?

To all intents and purposes, he's
got away with the murder of Diane.

Yet he's done it again.
Is it arrogance?

I think because he's gotten away
with the first one,

it gave him more confidence
in the second one.

I really do.

(reporter) 'This is the seven-bed,
£1.3 million house'

where Helen Bailey
lived with Ian Stewart.

Helen's brother John told the jury

that Helen joked that the cesspit
under the garage

was a good place to hide a body.

(Richard) 'Ian Stewart might
so easily have got away with murder.

Not once but twice.'

But the bodies of his victims gave
up the truth that had been hidden.
