In September 2017,
a young French nanny was tortured,

murdered
and thrown on a garden bonfire.

The fire brigade turned up, one
of them was putting the fire out

and stamping it out.

He realised that there was
a body in the ashes.

'They cooked chicken on a barbecue
nearby to try and hide the smell.'

Fingers, limbs, and part of a nose.

It was very grisly.

TRANSLATION: There are no words,
it's monstrous.

She beat her with an electrical
cord and she pushed and slapped her.

I'm going to kill you! OK? Be quick!

21-year-old Sophie Lionnet had
also been interrogated and tortured,

whilst filmed by her killers
Sabrina Kouider and Ouissem Medouni.

What you were listening
to was a quiet

and unassuming girl being harangued,
threatened and intimidated.

It was a torture video.

Sophie had been subjected
to what can only be

described as waterboarding.

She had four broken limbs
and a broken jaw.

I can't believe what they done to
her. She could have walked out.

I don't know why
she was stuck there.

She was trapped psychologically
and physically.

How did we not notice?
It's unbelievable.

This is one of the most tragic
cases that I've ever covered.

Southfields, a well-to-do suburb
of London,

just next-door to Wimbledon.

It's a safe place where people move
to bring up families.

We've lived here all our lives.

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

People know each other
because they stay a long time.

It's a unique part of London.

This feels like a village.

We call it the Southfields village.

Basically, you cannot
not know a person.

How about you guys?
Are you sharing with him?

Good friends.

Me being in there for 14 years, I
seen the whole world passing by.

We know each other, everybody
knows mums, the nannies.

This is what Southfields is,
family orientated.

But in September 2017,

a series of disturbing events
unfolded in the Southfields.

They took place at the home
of glamorous mother of two

Sabrina Kouider and her partner
Ouissem, or Sam, Medouni.

What happened was so gruesome,
so disturbing, that it

shocked residents to the core.

'The charred remains were
discovered by firefighters.'

'They cooked chicken on a barbecue
nearby to try and hide the smell.'

I saw smoke coming from the garden,
it was directly on the street.

You couldn't not see it.

My husband went to the corner shop
and as he passed the house,

he noticed the smoke.

He thought it was very
close to the end of the house,

so he was alerted on a safety level.

He just looked through the gate
and he noticed the gentleman

standing there,
throwing sticks onto the fire

and thought, someone's there
monitoring it, there's nothing more

that he can do, so he carried on.

The fire was in the garden
of Kouider and Medouni's flat

on the corner of Pulborough
and Wimbledon Park roads,

directly opposite the newsagent.

A couple of customers said that
there is a fire on Pulborough Road.

Somebody's doing a barbecue,

or it's too close to the patio
and there's smoke billowing.

One neighbour whose house is backed
onto the garden was

so concerned about the fire,
she rang 999.

I disappeared out the back
for a while and when I came out,

it was carnage.

Nancy called me and said,
"The fire brigade are here."

And I was passing by anyway, so I
stopped and we were chatting.

As we were chatting,
the police turned up.

The road has been sealed off.

There's about at least five or six
police cars. Two fire engines.

Then, they put up the white tent,
and they blocked off the road,

and we were thinking,
"Oh, what's happening?"

Eventually, another unmarked van
came, men in white suits got out

and that's when I realised that
something is quite serious here.

We couldn't understand
why there was the tent there,

why the police were there over a
fire. It didn't make sense to us.

And then, we saw Sam being escorted
out of the house with handcuffs.

The man who had been arrested
by police was Sam Medouni,

partner of Sabrina Kouider.

As Medouni was driven away for
questioning, forensic officers

arrived. It shocked the community,
who couldn't understand

why they were there.

But then, forensic investigators
carried out what looked like a body.

We saw a big red box,
not coffin shaped,

but quite large coming out after
the forensics had done their work.

There were lots of rumours
going around.

We heard they had found a body.

Police later confirmed there
were human remains in the fire,

but the body was so badly burned,

they couldn't even
identify the victim.

I can't remember how we found out.
I think it was probably
about a week later,

when they identified the body.

We had worked it
out by that point anyway.

I think most people knew
quite quickly through the process
of elimination who it was.

'Police have confirmed the body
found in the garden of a property

'in Southfields was French nanny
Sophie Lionnet.'

Neighbours had guessed correctly.

The charred remains in the
bonfire were those of the

21-year-old nanny who worked for
Sabrina Kouider and Sam Medouni.

When I had a reporter coming
in to me straightaway

and saying, "Do you know so-and-so?"
I was like, "Yes, I know so-and-so."

"And do you know she was murdered?"
And I couldn't speak.

Not only had Sam Medouni
been arrested,

but so had his partner,
Sabrina Kouider.

Within 36 hours of the discovery
of Sophie Lionnet's body

on the bonfire, both had been
charged with murder.

It is definitely an astonishing
thing to happen,

especially in Southfields.

The whole community was very taken
aback and shocked.

Completely shocking.

We couldn't understand what was
going on. It just seemed bizarre.

Really weird.

For months,
Sophie had suffered appalling

abuse at the hands of her
glamorous employer.

She actually started to cry and then
I had to ask her what happened

and that point,
she said Sabrina beat her.

Abuse that would
end in a murder trial,

described by the judge
as stranger than fiction.

I've been a reporter for 20 years
and this is the most bizarre

and also, one of the
most tragic cases.

On 20th September 2017,
firemen discovered

a body on a bonfire in a suburban
garden in South London.

A man and woman have been arrested
on suspicion of murder after

a body was found in a garden
in Southfields.

It soon became clear
that the remains were those

of Sophie Lionnet,
a 21-year-old nanny

working for mother of two
Sabrina Kouider and her partner,

Ouissem, or Sam, Medouni.

Kouider and Medouni had
lived in the rented ground floor

flat in Southfields since 2013.

They appeared to be a successful
and glamorous young couple.

Kouider was a fashion designer,
Medouni a financial analyst.

Local chip shop owner Michael Croner
immediately liked them.

Fish and chips?

We call him Sam, that was the name
he actually introduced himself,

saying, "I'm Sam."

And then, he introduced me
to Sabrina.

She was very polite, soft-spoken.
She was very glamorous.

Every time I see her,
she's well-dressed.

But Kouider had a dark side,
she was erratic, volatile,

and prone to mood swings,

and had a delusional obsession
with her celebrity ex-boyfriend

Mark Walton, founding member
of the Irish boyband Boyzone.

Walton and Kouider had a passionate
and turbulent relationship.

They separated in 2013,

but Kouider became obsessed
with and fixated by him.

It goes back about five years,

when Sabrina Kouider stopped
going out with Mark Walton.

She appeared to him to be a volatile
character, prone to mood swings,

but she also had
something of a hold over him.

She was prone to outbursts,
to shouting at random

people in the street and acting
in a strange and volatile manner.

They had an acrimonious split,
she left and he didn't know why.

At the murder trial, it emerged that
Mark Walton had helped Kouider

financially by paying the first
few months' rent on her Southfields

flat, but when he stopped supporting
her, Kouider became enraged.

When the relationship between
Kouider and Mark Walton broke down,

I think that was the catalyst

for all of the things that happened
subsequently.

She didn't take the breakdown well.

She wouldn't have taken
the breakdown well.

It's the kind of person that she is.

And she became fixated on either
getting him back, getting control

back over him, or, if she couldn't
do that, getting revenge.

Not long after the break-up,

Kouider started making serious
allegations about Walton.

The court heard she claimed
he was stalking her,

that he'd harmed her family.

All the allegations she made
about him were totally untrue.

Sabrina Kouider got it in her head
that she was stalking her, she said

that he was controlling her with
black magic and all sorts of things.

So the background to the murder
goes back a long, long way.

Well before they even met
Sophie Lionnet.

It was heard in court that Kouider
made more than 20 calls to police

and social services
about Mark Walton.

In every case, the police concluded
the allegations were not true,

that Kouider was a fantasist.

She even receive the police
caution for posting defamatory

statements about him online.

No-one knows why Kouider
developed her obsession.

It would appeal that Kouider
has certainly developed

a range of delusional thinking.

She certainly viewed the world
in a different way,

her approach to relationships
was very different.

It could be very impactful

in significant life events for her
that might have changed her

approach to relationships, affected
her self-identity and I think it's

more useful to think of Kouider from
that trauma-informed perspective.

Kouider also had a dysfunctional
relationship with

Sam Medouni, whom she had known
since childhood.

And although he lived at her flat,

he would often
disappear for months at a time.

They did seem odd.

The whole setup, working out
who was related to whom,

it was all a bit strange.

She was hardly ever there,
very glamorous.

He always wore a flat cap
and looked very shabby.

You wouldn't put them
together as a couple at all.

No-one really seemed to know them,
as far as I was concerned.

They weren't sociable. No.

They didn't come to street parties,

they didn't sort of chat
or introduce themselves.

They didn't want to be part of the
community, which is quite

an unusual thing around here.

They didn't want to
partake in anything.

Although the couple were thought
somewhat strange by neighbours,

it was Kouider's behaviour in
particular that stood out.

Sunny Patel remembers her causing
a scene in his shop, following

a disagreement over a mobile
phone voucher.

She was quite volatile and vocal in
her mannerisms with this dispute.

It was always probably her way,
or no way.

She called the police and two
policewomen turned up, one of them

took Sabrina outside because she
hadn't calmed down and then the

policewoman said to Sabrina, "Look,
this gentleman hasn't done anything

"wrong, but he is making an effort

"to assist you and you're
not appreciating that."

By December, a deluded and obsessed
Kouider was about to welcome

a naive young
nanny from France into her family.

Sophie Lionnet grew up in the
village of Paron, in rural France.

It's a couple of hours' drive
south of Paris.

She lived there with her mother
and stepfather.

TRANSLATION: Sophie is a nice girl,
always smiling, who loves life

and had a joy of living.

She was shy, yes.

We spoke very little,
it was always necessary to tear

the words from her mouth,
so that she could speak with us.

Sometimes, she chatted well with us,
but she was a very shy girl.

Sophie studied early years
child education at college.

Because she loved children
and children always came to her,

so she chose to do this job.

Sophie found it difficult to get
a childcare job locally,

so when a friend showed her
an advert for a French-speaking

nanny to work with a family
in London, she decided to apply.

TRANSLATION: She had never
left France.

Her goal was not to go
abroad to work,

but this opportunity would
open doors for her to find work.

So she said to herself,
that since I cannot get

work in France, I'm going to England
because it would be temporary.

It would give her experience, which
would help her find work in France.

Plus it would improve
her English there.

In January 2016, just after her
20th birthday, she came to London

and started working for Kouider
full time as her nanny.

When Sophie first arrived, obviously
I didn't know who she was.

I can remember
when she first asked for cigarettes,

I had to ask for her ID because she
looked quite well under 18.

I think she was very,
very shy and timid.

She was quite petite.

I don't think
she had a social life at all.

I have never seen Sophie
with anyone.

There are so many nannies round
in Southfields, they are very happy,

they meet up on weekends,
they even come to my restaurant.

They bring the kids.
They're all grouped up.

They have a social life as well.
But Sophie never had that.

From day one I knew her, she
was by herself, or with the family.

We assumed she was just part of the
family, just an aunt or a cousin,

a relative because she was with
the children all the time.

The amount of hours, the time,
the effort, the patience she had,

you could not pay someone
to do what she did.

So it was a natural assumption that
she was a member of the family.

Not the hired au pair.

For the first year or so,

no-one outside the family
took much notice of Sophie.

As this home video filmed
in the Southfields flat shows,

she seemed happy.

She spoke to the children,
she could speak to them easily,

but with anyone else, she just
seemed to be very withdrawn.

But Sophie did open up
to Kouider's friend, Jolanta.

It was my dream to learn French
and she offered for me

to help me with that.

I had a good chance to speak
with Sophie and she told me

that she came to London to improve
her English skills.

And she was planning
September to come back to France

and to study something related
with cinema.

It was her wish.

In the summer of 2017,

after Sophie had been with
the family for 18 months, Kouider's

obsession with Mark Walton took
another bizarre and twisted turn.

By now, he was living in Los Angeles
and totally out of reach,

so Kouider transferred some
of rage and frustration

onto her young nanny.

She exerted more control over her,
stopping her from eating.

Whenever she comes,
I offer her food.

She only has a
portion of chips and a drink.

And she eats it so fast,
the way she eats,

either she's not fed,
or she's rushing back to work.

She was pulling down, you can see.

I used to see her with the
same tops, same jeans,

and she never brushes her hair.

Kouider, who was now broke,
didn't pay Sophie's wages.

When Sophie was offered part-time
work by Jolanta to help out,

Kouider stopped all
contact between them.

I was just knocking to the door
and Sam opened the door and I asked

him or Sabrina is at home and he
told me Sabrina is not at home. And

after that I heard her voice
and I said, "Why are you lying

"to me? She is at home."

I think that Sophie was
controlled by Sabrina.

She couldn't decide
by herself where she can go

and I haven't even noticed
that she had her own free time.

Not only was Kouider starving
and isolating Sophie,

she was stopping her going home
to France, even to visit her mother.

I had to ask Sophie a couple
times, "How are you?"

And I can feel she had eyes very
teary and suddenly, she started to

tell me, "My mum is not well,
I need to go and see my mum."

I said, "If it is that, why don't
you fly to France, and I can even

"buy you a ticket? When you are
paid you can give me the money."

I offered that to her.

She didn't give me a positive
answer, neither yes or neither no.

She was just nodding her head.

And I didn't want to push her
on things.

Back in France, Sophie's mother had
received texts and Facebook messages

from her daughter, saying she was
unhappy and wanted to come home.

TRANSLATION: She sent me

a message saying she needed a little
bit of money to finance her return.

So I deposited the money in her
account as soon as I got my pay,

so she could buy her ticket
to return.

Sophie's mother then received a
two unexpected phone calls from

Kouider, in which she made
some strange allegations

about her daughter.

Sabrina had told me
she was keeping Sophie

because there were disagreements
and problems she wanted to solve.

I said to Sabrina, "Listen, do your
best to make her come home."

The situation between Kouider
and Sophie was getting worse.

Kouider was making increasingly
wild allegations about Sophie,

accusing her of stealing
a diamond ring

and of plotting against the family.

She actually started to cry and then
I had to ask her, "What happened?"

At that point,
she said Sabrina beat her.

So I asked why, which I didn't want
to, but I had to ask her why

and she said the way she said it,

"The butter fell off
and Sabrina beat me."

All of this was raising alarms, you
know, something is not right.

I said, "Sophie, if you want,
I'll find you a job."

I even spoke to a friend of mine
and he said send her immediately,

I can sort something out.

A couple of days after Michael
made this offer of help, Kouider

stormed into the chip top, dragging
a terrified Sophie with her.

I was just setting at my table
chairs outside

and she started to scream at me,
very loud.

And she didn't like Sophie speak
and she was screaming at Sophie

in French, which I didn't
understand nothing.

And then I knew this has got
nothing to do with me.

So I said, "Sabrina, you have got
to excuse me, I've got to go back
and open my shop."

And I left them there
and I walked away.

Michael suspected something
was wrong.

But he could never in his wildest
dreams imagine what Kouider

and Medouni were doing to
Sophie behind closed doors.

Imagine yourself every
day in a cage like an animal.

Or what they were planning
to do with her next.

In September 2017, the body
of French nanny Sophie Lionnet

was found burning on a bonfire
in south London.

Mother of two Sabrina Kouider
and her partner Ouissem Medouni

were arrested immediately
and taken into police custody.

Six months later, their trial
began at the Old Bailey, with both

defendants facing charges of murder.

The first time
I saw Sabrina Kouider, I thought

she was very beautiful
and very glamorous.

But also quite troubled.
She looked indignant.

She looked at me, shook her head
at me.

I think she almost enjoyed
the interest in her.

I just thought, how dare you
not be full of guilt or remorse

for what you've done?

Saying, "Tell them I didn't do it,
I didn't murder anyone."

It was quite fraught.

We knew right then that she was
going to be a difficult defendant.

My impression of Ouissem Medouni
was that he was very much

the quieter one.

Silent, brooding even.
A meek figure in the dock.

TRANSLATION: It was the first time
I saw them. It hurt me

because the had taken my daughter.

They had broken everyone's heart

and all the hurt they had done
to Sophie, I could not accept.

While both Kouider and Medouni
admitted to perverting the course

of justice by burning Sophie's body,
they both denied murder.

Both defendants had essentially
the same defence, that the

other person did it. They both
argued that they were asleep,

whilst the other person had
carried out the murder.

While no-one knew exactly what had
happened to cause Sophie's

death, the prosecution was to reveal
a key piece of evidence, which

clearly showed the extreme cruelty
she'd been subjected

to behind closed doors.

In the weeks before her death,
Sophie had been

the victim of a series of brutal
and violent interrogations.

Unbelievably, these sessions
were recorded by Kouider

and Medouni on a mobile phone.

I will not leave you alone
until you tell me the truth.

Is this clear? Do you understand?

These recorded interrogations
were all centred around Kouider's

obsession with her
ex-boyfriend, Mark Walton.

Kouider obviously couldn't get
to Mark Walton,

because by then he was
living in Los Angeles.

And she diverted all her anger
and anxieties

and obsession on to Sophie.

And she got it into her head that
Sophie Lionnet was working with

Mark Walton to spy on her
and to wreck her life.

She concocted in her head a bizarre
idea that there was a plot against

her and Medouni and so over time she
began to question Sophie for many,

many hours on end about what exactly
she thought had been going on.

Extracts of these
interrogation tapes

were played to a shocked court.

You will not go back to France
until you have told me the truth.

I'm going to spoil your life,
as you have spoiled mine!

She started coming out with all
these accusations about Sophie

meeting Mark Walton secretly
and plotting against her.

What you were listening
to was a quiet

and unassuming girl being harangued,
threatened, and intimidated.

They said that she should be
locked up for 40 years.

She was like a murderer... All
of this was to make her confess.

Whether you don't speak
or you don't speak at your trial,

you will do so. You will be jailed!

Kouider it was the one who
was instigating this whole thing

and she was the one that was keeping
control. That's very unusual.

In 95% of cases, it will be a man,
especially in this type of case.

You better know that we will
not let you go back

until we know the whole,
whole truth, nothing but the truth!

I think Medouni probably would have
been willing to do anything for her.

It's not even a case really of
whether he believed what she was

saying, it's that he believed

he wanted to do something
to please her.

The tapes contained
evidence not only of verbal abuse

but violence which had become more
and more extreme.

I think there were about eight
and a half hours of interrogations

in the weeks leading up
to Sophie's death,

and they got progressively worse.

There was evidence that Sabrina
Kouider beat Sophie at least

three times, she beat her with
an electrical cord and she pushed

and slapped her.

I'm going to kill you! OK? Be quick!

You can hear on the recordings,
noises that sound like slaps,

although Sabrina said that they
weren't her slapping Sophie.

But it did certainly sound like
she was being physically abused.

Think carefully about 40 years
in prison.

Close your eyes for one minute,

imagine yourself every
day in a cage like an animal!

I couldn't sit through all of it
because it was really too much.

Sophie's mother particularly
struggled to contain her

emotions and at one
point during this harrowing footage,

she broke down in tears
and had to leave the room.

TRANSLATION: There are no words.

It is monstrous,
it's moral harassment,

what they did.

I cannot stand it.

They destroyed the family.

They destroyed our life.

They hurt my daughter.

There really are no words
to express how I feel.

On the 18th of September,
after five weeks of interrogation,

Kouider and Medouni made a video
recording of Sophie, as

they attempted to get her to confess
to working with Mark Walton.

This is the last image of Sophie
alive, taken from that recording.

They ground her down so much that,
in the hours before her death, they

filmed her actually confessing
to colluding with Mark Walton.

It was clearly, completely untrue.

It was a figment
of Sabrina Kouider's imagination.

The worst part was seeing
the image of Sophie Lionnet

after everything that
had been done to her.

She looked emaciated, she looked
completely broken.

When Sophie's body was discovered,
it was

so badly burned it was impossible
to know exactly how she died.

Although, it was clear from the
postmortem that she had been

severely assaulted.

Sabrina Kouider said that she
accepted that she'd pushed

Sophie around, but she denied
being very violent towards her.

But Sophie had suffered
four broken ribs

and a cracked sternum three days
before her death

and on the night of
her death, she had a broken jaw.

Kouider and Medouni weren't shying
away from the fact that they

had put this young girl

through horrendous questioning
for many, many hours.

Their case was that each of them

denied the murder
that had taken place.

Sabrina said that it was all Medouni

and he had become absolutely
enraged, that he got a pan of water

and a towel and was torturing her,
demanding to know the truth.

Sophie had been held in the bath

and subjected to what can only be
described as waterboarding.

Sabrina woke up in the night
to find Sophie dead and said,

"What have you done?"

But Medouni said the complete
opposite and said that he was asleep

when all this happened.

But crucially, the prosecution
produced a witness that contradicted

both these stories.

One of the key pieces of evidence
in the trial was from a third party,

a witness in the house,
who had heard both Sabrina

and Sam in the bathroom with Sophie,

saying, "Breathe! Breathe!"

That was a critical piece
of evidence because neither one

of the defendants was really
telling the truth.

Also central to the prosecution's
case was the fact that the

authorities weren't alerted
to Sophie's death.

We know at some point they decided
rather than to call the police or

an ambulance, to dispose
of her body.

They built a bonfire in the garden
by their French doors,

by the kitchen and put Sophie's body
into a suitcase and lit the fire.

One of the neighbours called 999
and alerted the fire brigade to

a fire that was potentially
out of control.

When the firefighters arrived,

they found Medouni was at the scene,
apparently in control of the fire.

They insisted on putting
the fire out

because they were concerned that
it was a bit too close to the doors.

As one of them was putting the fire
out, and stamping it out,

he realised that there was
a body in the ashes.

I think he described seeing fingers,
and limbs, and part of a nose.

It was very grisly.

He turned to his colleague and said,
"There's a body in the bonfire."

Medouni, still trying to get away
with it at that stage,

trying to explain away the body
as the carcass of a sheep that

he'd bought at the market.

But it would have been
obvious to the firefighters

when they started looking through
the grisly remains that this

was not a sheep we were looking at.

It's clear from the evidence
that we heard that

had the neighbour not alerted
the authorities,

Kouider and Medouni could have got
away with murder.

The gruesome evidence about the
broken and despairing nanny being

beaten and tortured to death were
difficult for anyone to sit through.

But for Sophie's mother,
it was unbearable.

TRANSLATION: I do not understand
why they took to Sophie, she who

was so sweet, so charming...

I mean, she's a young woman
beginning her adult life.

It is a dream of all parents to see
their children blossom in life.

There are no words to understand
what they did.

Everybody has been saying that
Sophie was very naive and it was

easy to manipulate her and I think
that is true, but if we think that

the only people who get caught up in
coercive control are those people

who we see as easy to manipulate,
we would be making a big mistake.

Sophie behaved actually in the way
that many, many people behave

when they are being controlled.

At the Old Bailey,
after a gruelling 43 day trial,

the jury retired to decide
if there was enough evidence to

convict Kouider
and Medouni of murder.

But even now, neither defendant
appeared to show any remorse.

Really, all that mattered to Medouni
was Medouni and Kouider.

And no-one else counted.

And I think Sabrina was so wrapped
up in herself and her own world

that Sophie really didn't matter
and even throughout all

their evidence, in everything that
they said to the jury, they never

once expressed any regret or sadness

that Sophie had lost her life.

21-year-old French nanny
Sophie Lionnet was murdered after

being beaten and tortured by
mother of two Sabrina Kouider

and her partner, Ouissem Medouni.

After a gruelling murder trial,
where each defendant blamed the

other for her death,

the jury retired to consider
the disturbing evidence.

We had all been waiting for days

for the jury to come back
with their verdict.

It was a full court.

We were very conscious that
Sophie's family were very nearby.

We were all rather on tenterhooks.

After 30 hours of deliberations,
the jury returned their verdict.

When the verdict came in,
Medouni just hung his head.

Both Ouissem Medouni and Sabrina
Kouider were found guilty of murder.

Sabrina just started crying.

Sophie's mother, Catherine
Devallonne, started crying as well.

TRANSLATION: It's inhuman,
these acts of barbarism.

They never said a single
word of truth, it was all lies

and contradictions.

They never looked at me once,

or apologised for the harm
they had done to Sophie.

I do not understand what happened
in their heads to get there.

Like Sophie's mother, many struggled
to understand what had driven

Kouider and Medouni to such
unbelievable cruelty.

Mr Dee Anand is a forensic
psychologist,

specialising in
understanding offender behaviour.

The intensity of the relationship
between Medouni

and Kouider is of vital interest
in this case.

It's certainly the case that Kouider
have this delusional

belief about Mark Walton
and Sophie's involvement.

Medouni has bought into this.
Whether he's bought into this as a

form of delusional transfer or
whether he did this as a result of

dependency on his relationship
with Kouider is in question.

Kouider was the dominant
person in the relationship,

but Medouni was
there during most of the recordings

and chimed in occasionally
to ask his own questions.

So, he was part
and parcel of what Kouider was doing

and what she believed
Sophie had done to her.

When they were interrogating Sophie,
they were seeking to support

their own delusional way
of thinking.

They were encouraging Sophie to
confirm the delusions they had.

Sophie was quite vulnerable because
she had no support network here.

She had nobody to go to.

So, she was a perfect
person for Kouider to manipulate.

I think Kouider was
so convinced by her delusions

and Medouni also buying into this

was convinced that these acts
had occurred,

that there was so little Sophie
could've done to appease them.

Now, whether she was murdered
because the torture got out of hand,

or whether it was a deliberate,
premeditated act is only something

that Kouider and Medouni
themselves would know.

Sophie was never kept under lock

and key, but with the full extent
of the torture she'd suffered now

revealed, one question remains,
why hadn't she left?

She could have walked out, I don't
know why she was stuck there.

She can come
on to the street and tell help,

people would have helped her.
People might often ask the question

when they hear of a domestically
abusive relationship,

why hasn't that person left?

I'm sure some might be asking
that question of Sophie.

We have to understand
she would have felt trapped, both

psychologically and physically.

Her emotions would not have
allowed her or permitted her to feel

that she had the strength of
character to leave that household.

The things that Kouider had
been threatening her with,

Sophie probably thought
would happen.

She had been told she was a thief,
she was a sexual abuser,

that she was working in cahoots
with somebody else,

she would have been
terrified that had

she even got to the airport,
she would have been arrested.

Despite this, there is a sense of
collective guilt in Southfields.

How did we not notice?
It's unbelievable.

We would never have believed
something like that could happen.

It's so incomprehensible
to think that that happens.

Never mind so close to you.
You just don't expect it.

We feel really guilty, that
we didn't notice what was going on.

She was such a lovely girl and it's
just a horrible, horrible thing

to have happened right
in front of our eyes.

I feel guilty because we just
wish we could have done something,

she wanted to go back to France
and she only needed £20, or £25.

We would have given that to her.

I feel bad, I should have
gone to the next level.

Either made a complaint...
But that period was too short.

When that happened, I
think it's the week I saw her.

After that, I never saw her.

Nobody thinks that this kind of
thing is going on on their doorstep

and that's one of the things
that helps abusers

and controlling people
to do what they do.

It's because we all stand
around on the outside,

thinking, well, it
can't be that bad.

It's knocked our community,
it really has.

We're completely devastated by it.

And it won't be forgotten.

When you know you can help
somebody...

Sophie's mother hopes her
daughter's death will

serve as a warning to other young
nannies looking for work abroad.

TRANSLATION: I advise that parents
go with her children to see

the house and to meet the employers.

If there is a problem, bring your
children home, as soon as possible.

I'm a mother of two kids.

I think everyone has to be careful.

She was a bright person.

And it's so sad that in such a young
age, she needed to finish her life.

More than two years after arriving
to work in the UK as a nanny,

Sophie was finally returned home.

On the 6th of June 2018,
she was laid to rest in France.

TRANSLATION: The murder of Sophie
destroyed everything around us.

People don't understand.
The family is very shocked.

Her dad is shocked.
Her big sister too.

Her brother,
who has just turned eight.

He wanted to come with me
to England, to tell them

they had broken his heart.

And that they had broken
Sophie's life.

They must be locked up.

These people have destroyed
a whole family.

And all the people who loved Sophie.
