We were made aware that a body had been found in the river.
Those are diatoms,
bits of environmental evidence which can ultimately lead us to a suspect.
This was not a one-off incident.
You could see the sort of escalation of sexualised behaviour building up.
There were sex toy items, underwear and also some masks.
This is a very troubled individual.
It can be really surprising to find
that it's the very regular person next door.
It took all of us completely by surprise.
This is the road where she was last seen very late last Thursday night.
A week on, the fact remains Libby is still missing.
Your brain goes to very dark places.
I was working a night shift, and I was back at the nurses' station,
and I took my phone out and saw I had a missed call,
and it was nine minutes past one, so I called back and said,
"Oh, sorry, I've missed a call, is everything OK?"
NARRATOR: On the line is a friend of Lisa's daughter.
And she said, "No, we can't find Libby."
I said to her, "What do you mean, you can't find Libby?"
It was like...
The whole of my left-hand side had gone numb,
and I kept trying to tell myself everything would be OK.
21-year-old Libby is studying philosophy in Hull.
Her parents try calling her.
She didn't have her phone.
She'd left it at home, which was not unusual for her,
cos she would say to me,
"Mum, I'm out with my friends, why do I need my phone?"
Libby's friends call the police.
Libby had gone out for the evening on the Thursday,
gone to some friends,
had a bit of a house party before then moving on to the Welly club,
which was a normal Thursday night out for the students of Hull.
Libby had had a bit too much to drink,
and she'd been refused entry into the Welly club,
which then left her friends in a situation of,
"Well, we'll put her into a taxi, pay for the taxi,
"make sure she got home."
A few hours later, the friends were kind of texting Libby
to check that she'd got home OK.
They became concerned when Libby wasn't replying.
With any missing person, you kind of look at, think what could happen.
Because she's young, she's a student,
has she gone off with friends?
You know, actually, does she want some time out,
is she is safe and well and actually missing voluntarily?
When we find out obviously Libby left her phone at home,
that was one line of enquiry that, in essence,
was kind of blocked from the start.
12 hours later, Libby is still missing.
I knew Libby was going to a lecture at two o'clock,
and it was a really important lecture for her to go to.
I said to Russell, "|f she's not in that lecture,
"we're gonna have to go up there."
About ten past two, the phone rang and they said,
"No, she's not turned up for her lecture."
Libby's mum, and dad, Russell, rushed to Hull.
It was the most horrendous journey. I hadn't slept, obviously.
It was all really overwhelming.
And as we drove past the Humber, I said to Russell,
"She's in that water." He said to me, "Oh, don't be silly",
and I said, "No, I'm not being silly. She's in that water."
I knew I shouldn't feel that way...
...and you very much jump between absolute despair to hope.
By the Tuesday, it was starting to get a lot of momentum
and we were getting enquiries from a lot of national media outlets.
We rely heavily on the media in the initial stages of investigation,
because it draws witnesses out.
Proof of life is always what we try and find,
so the last known time somebody's alive.
The taxi driver came forward,
said yes, he was the one that took Libby home,
and kind of gave us his account.
He said that he dropped her off right outside the door
and he drove off.
So you then set the parameters around that home address.
It's virtually impossible not to be caught on CCTV cameras somewhere.
Was she with anybody? Was somebody following her?
Became aware of some footage along Beverley Road of a female,
and because of the timings and the last location we had,
that was more than likely to be her.
As you watch the footage, you can see that she's wobbly,
staggering around a little bit.
Ancl then as it unfolds, that to us became more and more confirmed
that that was Libby in the footage.
She was really upset about not being let in the club
and being sent home.
The mood she was in, I know that's why she went for a walk that night
and didn't go into her house.
A CSI attends Libby's home.
When someone goes missing,
the CSls would attend her student accommodation
and fingerprint items that we know that she's handled.
From a forensic perspective,
it's important for us to get samples from her
in order that if the worst case scenario is she's found dead
and she's decomposed,
then we're able to identify her through fingerprints and DNA.
Libby's keys are recovered on the street outside her address.
Something had gone hideously wrong.
The Libby that I knew and loved would never have left me or her dad
or her siblings or her boyfriend
in a place where they didn't know where she was.
She would have got a message to us if she could have done.
Yeah, your brain goes to very dark places.
It's really difficult for a CSI
that gets called out to an incident like this
to try and determine how serious the case is.
You know, is this going to turn into a murder scene?
RUSSELL SQUIRE: Libby is our kind, thoughtful, beautiful girl.
As you can appreciate, this is a very difficult time for us both.
LISA SQUIRE: It was a constant dialogue in my head,
but actually what it really was, was I knew that she wasn't coming home.
Please come forward with any information you may have,
no matter how small or irrelevant it may be.
We just want Libby home.
21-year-old university student Libby Squire
hasn't been seen since going on a night out with her friends in Hull.
It was really important early on that we got into the family
to find out everything we could about Libby herself.
I'd always wanted to be a mum and Libby made me a mum.
On the clay she was born, I picked her up and laid her on my chest,
and that's where she stayed for the best part of seven years.
Ancl yeah, we were really connected. Really, really connected.
Yeah, it was all my dreams come true in one little person.
It was amazing, truly amazing.
She was funny, caring, kind.
A really genuine person.
An amazing big sister, an amazing friend, amazing daughter.
just, you know, a really all round good person, I think.
Her mental health started to decline
when she was probably at the beginning of year eight.
There was lots of different issues that had gone on at school.
It was something I wish she hadn't gone through,
but it made us closer.
All of these things were part of Libby's complex character.
They didn't define her, but they were part of her.
Police ask if this is why Libby could have gone missing.
I hoped that. I hoped that she'd had a mental health breakdown,
but I knew that wasn't the case.
She worked for a whole... well, more than a year,
and really, really was coming out the other side and doing so well.
I was really excited for her when she wanted to go to university.
I was really proud of her. She said to me,
"Mum, I'd forgotten how much I love learning."
Ancl that just, oh, it just filled me with joy.
She really found herself.
She found the person that she wanted to be.
Internally, I had this really loud voice saying,
"She's dead. She's dead." Ancl I couldn't feel her.
REPORTER: This is the road where she was last seen
very late last Thursday night.
At 12.09 on Friday morning, she'd disappeared.
A week on, the fact remains Libby is still missing.
Police say it is their top priority to find her.
We decided to release images of Libby's clothing to the media.
We made contact with those manufacturers.
If we can say exactly what she was wearing,
that might just trigger a memory for somebody.
Several witnesses come forward saying they saw or spoke to Libby,
who appeared distressed but refused help.
just before midnight, the trail goes cold.
The search was huge for Libby.
Certainly, one of the largest I've ever known.
The amount of officers involved was enormous.
It was obvious from the start it was gonna be a long,
drawn-out search to cover all the area that was needed to be covered.
I used licensed search officers to search areas
where the victim was last seen, where she was travelling to.
A CSI could be attached to a licensed search team.
If they find anything,
it will obviously need photographing in situ and recovering.
It's a very structured search,
and if it's there to be found, they will find it.
As the search continues,
CCTV experts spot Libby further up Beverley Road.
From footage, we kind of see a man.
Ancl as we can see Libby walking,
he's mirroring her on the opposite side of the road.
That starts to give us a lot of concern.
We see a male approaching Libby and engage in a conversation
and we need to know who that gentleman is.
Libby and the man turn down a side street.
They are captured again outside a business premises.
What it did show was a vehicle pull up.
A male was sat with his legs outside with the car door open.
After a short period of time, he then disappeared again
and then a second figure that we believed could have been Libby,
you then saw that figure get into the vehicle
followed by the male into the driver's seat,
and then the vehicle move off.
We-We thought it possibly was Libby,
but it was really important to show Lisa and Russ that
to get their views as well.
They obviously know Libby better than anybody.
As soon as I saw it, I knew it was her.
From the way you could see that she put her hand up to touch her hair,
and that's what she did.
That was, you know, good because there was a development,
um, but scary.
It was pure chance, really, being able to get that.
Certainly, if he'd have parked further up the street,
we would have not been aware of him there or his vehicle there.
Police recover a watch from near to where the car was parked.
That had actually been found by a lady
and handed in to the police station,
and when we looked at that watch, we were able to show that
to Lisa and Russell, and Lisa was able to say that
that was Libby's watch
and she would have probably been wearing that at the time.
The team continues to track the car.
Through another CCTV trawl, we capture the vehicle
kind of coming back onto Beverley Road
and then down towards Oak Road.
The CCTV officers were then able to follow the vehicle
going onto Oak Road playing field.
That vehicle appeared to stay there
for a period of about eight minutes
before it had then left the area.
So that left us with the question of, "Well, where is Libby?"
CCTV officers then had the job of trying to track that vehicle.
There are no further CCTV sightings of Libby.
Obviously, the person in the vehicle was the last person
who'd have seen Libby.
It's really vital that we identify who this person is.
The playing field is secured and a fingertip search begins.
Searching a huge parkland area is a logistical nightmare,
and as a crime scene manager, you have no concept as to
what may or may not be important.
Had Libby dropped anything?
Had the offender dropped anything? Were there any good footprints?
Anything that might lead to the identification as to
where has Libby gone.
Oak Road playing fields is a substantial area.
The back of Oak Road playing field is the start of the River Hull.
Our consideration was, has Libby accidentally fallen into the river
or has Libby gone into the river by another means?
Ancl then, how would we recover Libby from the water?
Police go door-to-door.
One key witness reported being woken up by
the sound of a female screaming.
They looked out of the window
and they saw a dark figure running back along to where the car park is.
The man tells police he looked at his watch and it was 12.14.
If Libby was in that car at the time,
is that Libby that is screaming?
It starts taking the investigation into another direction -
that something has happened to Libby,
she has been the victim of a violent act.
The team continues to track the vehicle.
After the vehicle had left Oak Road playing field,
it had then returned into the Newland Avenue area of Hull,
just driving around.
He'd been doing that for the hours
leading up to Libby's disappearance as well.
He'd spent practically all evening and all of the early hours
just driving aimlessly up and down and around and around.
The footage is either too dark or grainy
to get a good look at the number plate.
just over three hours after being seen with Libby,
the man is captured stalking another woman.
The male in the vehicle is seen to get out. He's on foot.
He's masturbating in the street,
so that is creating alarm bells as to his behaviour.
Since Libby's disappearance,
a number of women have come forward with similar concerning reports.
We did get a lot of calls from members of the public in the area
that had been victims of voyeurism-type crimes,
people who'd been followed
or they'd seen somebody in the street exposing themselves.
With Libby disappearing, that seemed to make people
want to report that more in case it was possibly linked.
Some of them were sexual of fences -
voyeurism and outraging public decency.
Others of them were burglaries.
Stealing underwear, sex toys.
When we think of burglary,
we think of it in terms of financial crime.
However, in the criminal histories of sex offenders,
the burglary actually serves a different motivation.
It's to take away very specific objects
for their own personal gratification.
The team need to determine
if the of fences are linked to Libby's disappearance.
We were keeping an open mind. There were some similarities.
It was all in ancl around that student area,
but because the descriptions were of a similar, quite generic...
male, white, dark hair, mid-20s...
...it was too generic to say it was the same person
committing all of the of fences.
We needed something specific to say that we had kind of
somebody who is committing these other of fences in that area.
We had a report from a lady who stated that on Boxing Day
her daughter was walking home into close proximity to where Libby lived
with a friend, and they were being followed by a male.
When they got home, that male kind of came into the porch way
and then masturbated up the front door.
As the Libby investigation was going,
the mother reported that to the police.
Forensic teams went to the address and examined the door
and then semen was recovered from the door.
Some sexual offenders might use what we call a calling card
at the place where they engaged in their sexual offence.
He's left a piece of himself there and I think that would give him
an extra thrill, an extra kind of sexual gratification.
DNA swabs and fingerprints are collected from the crime scenes.
The DNA profile was loaded to the DNA database
and it didn't match anybody,
so from a policing perspective, that's quite frustrating.
It was a serial offender who was getting away with this.
That would spur the police on even further.
They needed to find out who this person was.
Police need to determine if the offender is the man
last seen with Libby.
Through the CCTV, we were able to track it to
where it eventually parked up.
The male had got out of the vehicle and had walked along Newland Avenue
and he'd walked past a location with some really excellent CCTV,
and it was at that point where we'd got a clear image.
We were able to identify an address
that we believed that male to live at.
His name's Pawel Relowicz and he is a Polish man,
moved across with his wife and two young children.
We need to go to that property
and have that person arrested for offence of kidnap,
because at that moment we still didn't know
if Libby was dead or alive.
Police swoop on Pawel's address.
When the arrest teams get there,
you don't know what you're going to find.
In Hull, police raid the address of a man last seen on CCTV
with missing student Libby Squire.
The first thing is to look, check if Libby's there.
What surprised the arrest teams was it was just a normal family home.
Toys, normal daily living.
There was nothing in relation to Libby in the home address at all.
Pawel Relowicz is arrested on suspicion of kidnap
and taken into custody.
Nothing out of the ordinary in his appearance at all.
Serious sexual offenders can often appear really, really normal.
There's often this kind of traditional idea that sex offenders
are these old men in dirty macs standing around alleyways,
but in reality, they walk among us.
They keep their sexual deviancy hidden, of course they do.
At the police station, he's booked in.
POLICE OFFICER: 'If you could give me your full name, please.'
INTERPRETER TRANSLATES
'Pawel Relowicz.'
'So my next question is very simple.
'Are you responsible for kidnapping Libby Squire?'
INTERPRETER TRANSLATES
'N0.'
Initially, he denied knowing Libby, seeing Libby.
He was softly spoken, almost childlike at times.
You know, he would laugh inappropriately at certain moments
when he was tense or under pressure.
He answered questions politely and so
he wasn't quite what I was expecting.
Police noticed scratches on Relowicz.
POLICE OFFICER: 'Tell me about the mark on your face.'
SPEAKS IN OWN LANGUAGE
INTERPRETER TRANSLATES: 'I Wear glasses all the time, you know.'
SPEAKS OWN LANGUAGE
'And with my son, I would always...'
SPEAKS OWN LANGUAGE
'..pull them and he would always throw my glasses somewhere.'
Detectives confront him with the CCTV footage.
POLICE OFFICER: 'Explain to me any involvement or knowledge
'you have about the disappearance of Libby Squire.'
SPEAKS OWN LANGUAGE
INTERPRETER: 'I can only tell you how things happened from beginning.'
Then his account changed that, yes, he did know her.
He'd picked her up, she was kind of worse for wear,
he was being the good Samaritan.
He started saying that
Libby was kind of making sexualised moves towards him
and because he wasn't like that, he ordered her out of the vehicle
and left her near the playing fields.
I remember feeling quite sick.
It means that she hasn't walked off on her own.
It's kind of closed off quite a few avenues of what could have happened.
Relowicz's house is searched
and his car is taken to a forensic garage for analysis.
The vehicle was searched for Libby Squire's DNA and fingerprints.
There was no evidence to put Libby Squire in that vehicle.
Doesn't mean to say there was no evidence there in the first place.
He might have cleaned the vehicle.
Although no traces of Libby, the team makes a disturbing discovery.
In the boot of his vehicle there was a holdall.
Within this holdall were some very strange items.
There were sex toy items, there were items of underwear
and also some masks.
This obviously indicates that this is a very troubled individual.
Officers also find used condoms
and images of women taken without their permission.
A term we use in order to understand sexual offending is paraphilia,
and this refers to an intense focus on either an object or an activity
they gain a sexual thrill from.
The hoarding of items like this
is often quite typical of sexual offenders
because it means that they can keep engaging in their objects of lust.
POLICE OFFICER: '|'m going to show you a scenes of crime photograph
'of contents of a pink and blue bag.
'Why are those soiled knickers in your car?'
HE LAUGHS POLICE OFFICER: 'What's funny?'
INTERPRETER AND SUSPECT SPEAK IN POLISH
INTERPRETER: 'Because I am a normal guy and I don't do such things.'
At his home, officers continue the search.
We found a PC computer.
This would have been taken away for analysis
because, obviously, the police officers want to work out
what he's been doing on his PC, who he's been in contact with,
what sites he's been looking at, etc,
and if there's any evidence on the disappearance of Libby Squire.
Some items of women's underwear were hidden inside that computer tower.
These would have been recovered and then be examined for DNA
to see if they can link up to anybody.
None of these items link to the disappearance of Libby,
but the police clearly think he's very suspicious.
Cos he was arrested,
the police were able to take his DNA and fingerprints.
The DNA sample that he provided was loaded onto the DNA database.
We then started getting match results linking to
the previous reported non-contact sexual of fences.
POLICE OFFICER: 'The first alleged offence burglary, dwelling,
'secured on Friday 31st of August 2018.'
They were able to link several different crime scenes
on the DNA evidence.
POLICE OFFICER: 'The next one is voyeurism and exposure.
'The third one was outraging public decency.'
Relowicz is charged with 13 non-contact sexual of fences.
My early advice to the police and to the Crown Prosecution Service
was to not charge him with murder.
Whilst we could prove that Relowicz was the last person
to have seen her, and he was being dishonest about his movements,
we couldn't actually prove at that stage reliably that Libby was dead
or that she had died by his hand in some way.
The longer the investigation went on,
it did become apparent to us that the likelihood was that
she had ended up in the water, that she'd gone into the River Hull.
We had an oceanographer on the case and he had basically said,
"You know, if she's in the river and if she comes back,
"it will be sort of six to eight weeks' time."
You know that the chances of finding Libby safe and well
are diminishing.
In the back of your head, there's always a glimmer you'll find her.
Seven weeks on from Libby going missing,
a fisherman calls the authorities.
We were made aware that a body had been found in the river
and that was being forensically recovered.
Initially, we didn't know who it was.
She said, "Can you talk?" I said, "Yes."
She said, "We think we've found Libby's body."
I felt numb.
The most important thing is to discover who that person is.
So the police would look at kind of
primary and secondary identification markers.
Clothing would be an identification marker. Any possessions.
Main markers would be dental records and also fingerprint identification.
The chances of it being Libby were quite high.
The reason for that was because Libby had been bought a necklace
on her 21st birthday,
which was a gold necklace with a gold "L" pendant
and that was still seen on the body.
The woman's clothes also matched what Libby was last seen wearing.
The body is transported to the mortuary.
The police were able to recover fingerprint detail from
the body's hands and they were able to identify that
this was the missing person, Libby Squire.
I felt like everything had ended.
It was horrendous, didn't fall in a heap on the floor,
but I do remember sort of just sinking into the chair
and just feeling nothing.
My worst fears had been realised.
When we got confirmation it was Libby...
..|'ve never seen the enquiry room...
...change so much.
There was a lot of sadness, also a lot of, erm...
...kind of relief in one way that we found her,
we can get her home to her mum and clad.
From looking at the tide times,
if we hadn't have recovered Libby then,
we would never have recovered her, cos the next clay,
she'd have gone out into the North Sea.
Lisa insists on seeing her daughter.
I was desperate to see her.
It was a week after she'd been recovered,
and, yes, she didn't look like Libby used to look,
but she was still my little girl, and...
and it was about being with her and thanking her for coming back
and for telling her she looked beautiful cos, to me,
she looked absolutely gorgeous,
and just sort of saying to her, "You're back home now.
"You're safe, and no-one can hurt you any more,"
and, you know, how whilst I've got breath in my body,
I'll fight for her, and, you know, yeah, and being...
and just being in the same space as her.
Now a murder investigation,
police still needed to determine how Libby died.
At the postmortem stage, it was impossible
for the pathologist to ascertain the cause of death,
mainly due to the decomposition.
Marks on the body could have been caused
by the turbulence of the water.
One of the main lines of enquiry was
was Libby dead or alive when she went into the water?
Because her body had been in the water for seven weeks.
Obviously, her body...
The lungs wouldn't give us that information.
The team needs evidence to support their theory
that Libby entered the water at Oak Road playing fields
after Relowicz drove her there.
They call in forensic ecologist Rosie Everett,
a specialist in microfossils.
My involvement with the case was about trying to ascertain
whereabouts she had been put in
and how long she'd been in the water for.
If you look at it under the microscope,
you'll see lots of tiny, little shapes,
circles, triangles, and those are diatoms.
Diatoms are microscopic single-celled algae.
They grow in big colonies,
and they grow in different water conditions,
so a freshwater river will have different diatoms
to a more salty estuarine system.
The police were hoping that the diatom evidence
would be able to prove
that Libby's body had been dumped further upstream,
and then the sheer weight of the water and the currents
had pulled her further downstream into the estuary.
Ancl what that means is we have to go out
and take either soil or water samples
from across different locations
where we think Libby came in contact with that water.
As well as working out where Libby died,
the team need further evidence that proves Relowicz is her killer.
Internal swabs are sent for forensic examination.
Normally, anybody who's been the victim of a sexual crime,
we have a seven-day forensic window
just because the body will degrade those cells.
I don't think anybody was expecting it to be
a positive forensic result coming back
after a body being in the river for seven weeks.
Six months on from his arrest,
Relowicz pleads guilty to 13 non-contact sexual of fences.
He's sentenced to just under six years.
Often, these are dismissed as trivial sorts of of fences,
but actually, you could see in the victims of his of fences
that the effect on them was far from trivial.
All of the of fences took place in and around the student area of Hull,
and that was very significant because it was the same area
in which Relowicz had come into contact with Libby Squire.
It was not a one-off incident.
This was regular, persistent conduct.
You could see in the conduct that he was getting bolder.
It was good to know that he was held in custody on other things,
which meant he couldn't go out, he couldn't abscond, you know,
he couldn't go back to his home country,
and he couldn't do it to anybody else.
With Relowicz behind bars, the team focuses
on potential evidence recovered from Libby's remains.
This is one of the first cases that looked at clothing fibres
for diatom analysis, and what we found,
the fibres had absorbed pretty much every diatom ecology
in the entire River Hull, Humber Estuary, North Sea system.
Now even though we couldn't give a direct location,
it did narrow it down to her last sighting.
So we know that it was definitely around the River Hull
that she was put in, which in turn supports
other types of evidence such as the last known sighting on CCTV.
The evidence is consistent with the police's theory
that Libby entered the water at the playing fields.
Having scientific evidence is absolutely crucial.
In terms of Libby's body revealing how she'd been killed,
we didn't get an enormous amount of help.
We all thought that we needed to have
some sort of breakthrough evidentially.
Everybody had been told we're gonna have a briefing,
so people were thinking, "Has something happened?
"There's clearly some information to be shared."
KELLY ADAMS: After recovering the remains
of 21-year-old Libby Squire from the Humber Estuary,
detectives leading the case have a development.
Everybody had been told we're gonna have a briefing.
We're told that the DNA recovered from swabs taken from Libby
had identified Pawel Relowicz's semen.
After several weeks in the water, it was significant, and,
to be honest, I've never heard of that before,
that length of time,
and it took all of us completely by surprise.
That was a crucial moment in this case.
It was a moment at which we knew
that he was lying about his contact with Libby
because Relowicz claimed
that he had had no sexual contact with Libby Squire at all,
that he had left her alive and well
and that nothing had occurred between them,
and yet there we had his DNA, his semen,
and that blew his account to pieces.
We knew that it was a rape charge if nothing else, and it felt good.
It felt good that, actually, she hadn't...
she hadn't died in vain, you know?
She was gonna get some justice.
POLICE OFFICER: You are under arrest for the murder
and rape of Libby Squire...
...in Hutton Friday the 1st of February 2019.
INTERPRETER SPEAKS IN POLISH
RELOWICZ SPEAKS IN POLISH
INTERPRETER: It's impossible.
RELOWICZ SPEAKS IN POLISH
What I mean is I haven't clone anything.
This is 100% sure I would have never killed a human being.
The fact that the offender laughed,
I don't think it's actually necessarily a sign
of somebody not taking it seriously.
I would interpret that as a sign of stress, and,
actually, quite extreme stress, perhaps because he's realised
the amount of evidence that's piling up against him.
Despite the DNA evidence,
Relowicz continues to protest his innocence.
When they went back in to interview with Pawel,
he did confirm that they had sex and instigated by Libby,
and it was consensual.
It was very, very unlikely that Libby,
in the condition she was in, the type of person she was morally,
would have had consensual sex with Pawel Relowicz
on Oak Road playing field.
The fact that we've got a member of the public
hearing screams coming from that location,
none of that was supportive that this was a consensual sexual act.
After he had left Libby at the playing fields,
he was seen masturbating in the street.
That was significant.
What it demonstrated was that this was a man
who had an insatiable sexual appetite.
Relowicz is charged with rape and murder.
As the team prepares for trial, Libby is laid to rest.
She grew up and spent lots of time on the hill at West Wycombe,
and the church is on top of the hill,
so it was a really obvious choice, really.
There was about 400 people in the church.
It's a really tiny, little church...
and it was just so lovely to see all those people
that had come out to say goodbye to her.
She'll never die in all of those people's minds.
You know, she's always there.
Relowicz, flanked by lots of prison officers,
looked small and insignificant in the clock.
He was a very quiet, softly spoken man, and,
you know, if you didn't know what he'd clone,
you might be persuaded that, you know, he couldn't have done this.
Often, it can be really surprising to find
that it's a very regular person next door
who's engaging in these kind of acts.
What we know from the profiles of people who commit
extreme sexual of fences is that very rarely are they...
in the grip of something that they can't control.
Relowicz insists Libby consented, and his defence argues
he wouldn't have had time to kill AND put her body in the river.
The CCTV compilation was absolutely crucial,
and the police did a fantastic job in tracking down
every last scrap of CCTV footage.
And we were so fortunate
that the CCTV included footage from a neighbour's house
that just caught the narrowest beam of light from his car headlights.
He went back to the playing fields.
We could prove when he got there and when he left,
and that was, in my view,
a particularly devastating piece of evidence.
We will never know, but it certainly extended
the window of his opportunity to do all those things.
The jury retires to consider their verdict.
They were out for about a week, a very long retirement.
This was not a foregone conclusion that there will be a conviction,
so I think everybody felt a massive pressure in the case...
...and then ultimately comes that moment where you're told
they've reached a verdict.
Relowicz is found guilty of Libby's rape and murder.
Relowicz was sentenced to life imprisonment
and ordered to serve a minimum of 27 years.
There was a definite sigh of relief
from everybody within the courtroom.
There was a lot of emotion.
It's kind of that bittersweet,
because, obviously, Libby's lost her life. Erm...
I feel... proud that Pawel has been rightly convicted.
He can't hurt anybody again.
She had come back, and she had given the evidence
that nobody ever expected her to give,
and she got him behind bars.
In Libby's memory, Lisa is campaigning for more people
to report non-contact sexual crimes to the police.
Out of a group of, sort of, 20 of my friends,
each and every one of us has been a victim
of a non-contact sexual offence at some point.
Things need to change.
This has been going on for far too long.
I work quite closely with the Met and Thames Valley Police.
I go into schools now, schools, colleges, six forms,
and talk to them about the importance of reporting
any non-contact sexual offence.
Non-contact sexual crimes, such as voyeurism or exposure,
were often taken as trivial,
but actually, what recent research tells us
is that they often form a really important stepping stone
in somebody's sexual criminal career.
The fact that the offender went back out
looking for another victim
only a few hours after he had killed Libby
shows that his sexual offending was increasing,
not only in terms of severity but also in terms of frequency.
If the police don't know anything about it,
they can't do anything about it.
Reporting these non-contact sexual crimes to the police
could prevent someone being attacked by a predator.
She is a really, really strong woman
who has been through a lot,
but she's been able to take the strength from that
and to try and prevent anybody else going through
what Lisa and her family has.
The overwhelming feeling that we got
was that everybody was so sorry that had happened in their home city,
because Libby loved Hull.
It's a really friendly, really lovely city.
Because of her, the streets of Hull were safer.
Yeah, I think she'll be remembered up there for a very long time,
and there was a real feeling of love.
I miss her.
She was my funny, caring little pie.
