00:11I'm David Wilson, Emeritus Professor of Criminology, and for over 30 years, I've
00:17investigated the phenomenon of murder and what it is that might motivate someone to kill.
00:27Every murder case is different, but time and again, a deadly pattern emerges of warning
00:34signs and red flags.
00:40In this new series, I investigate some of the UK's most harrowing murder cases to understand
00:48how and why these terrible crimes occur.
00:55This is Murder UK.
01:12In Berkshire, in the home counties, half-sisters Kylie Denbury and Tara Randall grow up inseparable.
01:20She was very caring, wanted to do everything for everyone.
01:25She was very, like, cheeky, and she was gobby, but that was nothing that we weren't used to.
01:33Just sassy.
01:39Kylie's mum met and married Tara's dad in 2000.
01:43Kylie wasn't.
01:44It was a bustling family home with five siblings.
01:48The sisters could be a handful.
01:51Kylie, in particular, was known for her energy.
01:55She was funny.
01:58Loving.
02:00She could be naughty.
02:02She used to wear my clothes.
02:06She definitely didn't like school.
02:08She used to go to the clubs, friends, parties and stuff.
02:13But she wasn't bad.
02:16Tara naturally grows protective of her younger sister, who suffers from epilepsy.
02:22But as they enter their teenage years, Tara begins to mature and her interests shift to boys,
02:29and to one boy in particular, Mark Sinclair.
02:33When I first met Mark, I was about 17.
02:37Literally met him, and within, like, I think it was about three months, we were dating.
02:43He was just very kind, caring, just a nice, genuine bloke.
02:49Tara's relationship with Mark Sinclair develops rapidly.
02:54And as it does, she begins to see a disturbing change in him.
02:58I fell pregnant with my first child at 17.
03:03Then the drugs started, the drink.
03:05He became nasty, like, real spiteful.
03:12Wanted to cause an argument all the time.
03:15As Sinclair and Tara settle further into teenage parenthood, his behaviour worsens.
03:22When I've had my eldest, the beginning was fine.
03:27Then when he was about three, three months old, the drinking got worse.
03:35Um, I had to call the police because he'd left my house with my son.
03:44If I refused to give him money for drugs or drink, it would just cause a big uproar.
03:50When I refused to give him money one night, um, he literally threw me out of my bed with my
03:56son in my arms.
03:57You could just see the rage in his eyes.
04:01Sinclair, who'd been in care himself from the age of 11, clearly struggles with parenthood.
04:09Dr Donna Youngs has researched his mental health, including the diagnosis of a serious personality disorder.
04:19Disocial personality disorder is, it's almost like a low-level psychopathy.
04:24It's one that was formed very early in life.
04:28I mean, we're talking before the age of seven, before the age of eight years old.
04:33He rejects, he renounces all the normal social ways of going about doing things.
04:40Um, he has a recklessness.
04:42There's a callousness, a callous streak to him alongside, curiously, alongside a very, a very passionate, intense, loving streak.
04:55Former detective Paul Barton believes Sinclair's diagnoses, when combined with his recreational drug use, created a potent recipe for disaster.
05:09Sinclair had been known to the police since he was 17 years of age.
05:13There are a number of people in this country that have personality disorders.
05:17Um, not all of them are managed by the police.
05:19But I think this is particularly tricky when somebody with a personality disorder is also addicted to substance abuse, such
05:26as drugs or alcohol.
05:28Because the effects that has on those individuals is they become more volatile, um, they become more paranoid.
05:34But also probably the medication they're supposed to be taking for their personality disorder is actually not working because of
05:39the other substances they're taking.
05:41He had quite an extensive criminal history, which include a range of serious sexual assaults, violence, threatening behaviour, and also
05:49weapon offences.
05:50So he was quite a dangerous person.
05:54Mark Sinclair's psychology is, well, quite simply alarming.
05:59When you combine a diagnosis of antisocial personality disorder, which would have a lack of empathy, a recklessness to it,
06:11with chronic substance abuse, you've got somebody who really does not know any social boundaries whatsoever.
06:19And the drugs aren't creating that psychology.
06:23What they're doing is stripping away any last vestige he might have about social convention, about rules, about boundaries.
06:35And therefore, Tara's living with a very dangerous man indeed.
06:38Tara's living with a very dangerous man indeed.
06:41Initially bewitched and seduced by Sinclair's charm, Tara doesn't know the man she's actually with.
06:50She's unaware of his mental health diagnoses.
06:53And she certainly doesn't know of his extensive contact with the police prior to their relationship.
07:01This included being charged at the age of 17 with sexual assault against a minor.
07:09He was a completely different person.
07:12Completely different person.
07:13He was nasty.
07:15Everything had to be his way.
07:18And he was just evil.
07:19Absolutely evil.
07:23Bearing witness to Sinclair's increasing abuse of Tara, younger half-sister Kylie often steps in to offer support.
07:32Kylie used to come and babysit the children for me when we used to go out.
07:36Obviously, some of it she was there for, so she did see quite a lot.
07:42In 2008, having had two children with Tara, Sinclair's drug use and his lifestyle choices lead to a prison sentence.
07:53And it's at this critical time that social services intervene.
07:59They'd done all their assessments and they basically said because of the domestic violence part of it,
08:07they would take my children for their own protection.
08:09So, basically, it was him or my children.
08:13I chose my children.
08:15I didn't want to be with him.
08:17At that point in my life, I'd got to the point where, like, I actually don't want to be with
08:22you no more.
08:24Social services knew their priority was the children's permanent safety.
08:29They had to assess the long-term risk Mark posed given his conviction for a violent offence.
08:36Even with Mark behind bars, Tara was given a stark, non-negotiable choice.
08:43Sever all ties to him now or the children would be removed.
08:48Tara is finally free from Sinclair and his increasingly dangerous level of abuse.
08:55But on his release from prison, a shocking secret is revealed.
09:02Mark and Kylie had been seeing each other.
09:08Mark and Kylie met when Kylie was babysitting for Mark and Tara, Kylie's older sister, which tells us Mark doesn't
09:21subscribe to the normal social rules of behavior.
09:26Sinclair dating Kylie, Tara's sister, is simply another form of control.
09:35It's the ultimate form of betrayal for Tara herself.
09:39It further isolates her.
09:42It further can degrade her own sense of self-worth.
09:48And, of course, this goes back to Sinclair's underlying psychology.
09:53This is somebody who can empathize with another person's feelings.
09:59And so he must realize the impact on Tara when he starts dating Kylie is to make her feel even
10:08more abandoned, worthless, degraded.
10:28What exactly does Kylie Denbray see in Mark Sinclair?
10:33I think it's that bad boy type image, because that's how he comes across, is a bad boy type person.
10:42The fact that Kylie, when she met Mark, would have been very naive, very impressionable.
10:50She was so young, 16, is a real factor in the way their relationship formed.
10:59This relationship beginning in this clandestine way.
11:04Her being chosen above her sister in some ways.
11:10And I think that all this excitement, all this drama, and the charisma that I have no doubt Mark has,
11:19would have literally swept her off her feet.
11:23At the news of the relationship, older sister Tara is immediately concerned.
11:28I said to Kylie that obviously I didn't want the contact because I didn't want him knowing anything about my
11:35children.
11:36But other family members are not worried.
11:39Mum Teresa doesn't know about Sinclair's dark criminal past.
11:47Kylie had been seeing him for a few months before we actually met him.
11:54He seemed kind.
11:56He treated Kylie like a princess.
12:00Obviously he made her happy.
12:07In 2008, Kylie and Sinclair move in together.
12:12I think the choice that she has made has been a particularly unfortunate one because he can be so deceptive.
12:21Because this covering of attractive, charming, charismatic qualities is just that it is a facade beneath which this very different
12:34personality also lingers.
12:37They seemed like a really good couple together.
12:42But over the course of their early relationship, Mum Teresa does begin to notice things.
12:49Things of serious concern.
12:52Used to come home and she would have a bruise or a mark on her body.
13:01Obviously, when I used to ask her, she would say things like she had fallen over, but she wouldn't tell
13:11us the truth.
13:14I said to her, why do you want to be with someone who's controlling, telling you you can't wear this
13:23and you can't wear that?
13:29Perhaps it's because like Sinclair, Kylie herself had been diagnosed with a personality disorder.
13:36Hers, however, makes her prone to unstable relationships and a deep worry that people might abandon her.
13:46How does she know just how abnormal it is for her to be in fear of violence from her partner?
13:53How would she know she doesn't have that background experience?
13:57What we have with Mark are two very distinct components to his personality.
14:02So we've got this intensely loving, passionate, doting, romantic side of him.
14:10And then this ever-present violent potential waiting to be unleashed.
14:19Later in 2008, Kylie receives news that intensifies her connection to Sinclair.
14:27She's pregnant by him.
14:30When Kylie first found out that she was pregnant, she was like any mother.
14:37She was excited.
14:40She couldn't wait.
14:44The pregnancy, however, doesn't give any pause to the abuse.
14:49Though Kylie will often downplay, rationalise and contextualise it.
14:56It's quite common in sort of long-standing domestic abuse situations when the police get called and the perpetrator is
15:05arrested and they're taken back into custody.
15:08And then the victim has that kind of cooling off period, that downtime to start thinking about the consequences.
15:14And it's not uncommon for a victim of domestic abuse to actually change their mind and say, you know, I
15:21don't want to press charges.
15:24In September 2008, the authorities do recognise Kylie as a victim.
15:31Sinclair hurts her badly.
15:33He's arrested and pleads guilty to battery.
15:37This is the police's first official record of contact with the couple.
15:42And they talk to Kylie.
15:45I don't think Kylie ever saw herself as a victim and I'm fairly confident Mark wouldn't have allowed her to
15:53see herself as a victim.
15:55On release from custody, Kylie allows him back into her life.
16:01Came out of prison a month before baby was born.
16:07Their child's birth offers a moment of relief.
16:11They seem to have put it all behind them.
16:14We were all happy.
16:16Mark was excited.
16:20Cried.
16:22And it was just a happy day.
16:30So you've got to remember that Kylie was only around about 16 years of age when she first met Mark.
16:35So then suddenly be in love and loved by an individual, you know, and have a child with them has
16:43probably had a massive impact on Kylie.
16:45You know, she doesn't know any different.
16:46And I think she really relies on Mark, you know, who's probably said, if I go to prison, who's going
16:52to look after the kids?
16:53Who's going to put food on the table?
16:54We're talking about an emotional dependence where he had a, he had a drug addiction, but she certainly had an
17:00emotional dependence on him.
17:03By 2009, calls to the police about abuse at the house Sinclair shares with Kylie come in thick and fast.
17:11And mum Teresa begins to see the physical evidence for herself.
17:16He had no respect.
17:18He used to smash my house, punch the doors.
17:24It was scary.
17:26You didn't know what to say to him.
17:30He would go for you.
17:35She's done it to me a few times.
17:39One of the questions that I think most people ask in situations like this is why does the person being
17:49abused not get up and leave their abuser?
17:53It's not as simple as that for a number of different interacting reasons.
17:58The first is after she has been abused, there would then be an intense period in which Sinclair would show
18:06her love.
18:08And that relationship between what's healthy and what's abusive becomes blurred.
18:14And we know from decades of research about domestic violence and coercive control that ironically, the person being abused is
18:25at greatest risk when she articulates the fact that she is going to leave.
18:32Now, the risk is not just to Kylie, but also to their young son and reports of domestic abuse and
18:41Mark's previous convictions bring the couple urgently to the attention of social services.
18:49We know that the child was taken away into care by children's services, and that's an extremely serious step to
18:55take, taking a child away from its mother.
18:58But I can only assume that the social services and other partners had considered the risk that Mark posed towards
19:06Kylie and felt that was the only opportunity they had to safeguard that child.
19:12You've got to remember the police have been called on a number of occasions to this address where Kylie had
19:17refused to support a prosecution.
19:20And therefore, you know, if she was making excuses for Mark's behaviour, how could she possibly safeguard her children?
19:26It made me feel very angry, upset. I couldn't believe it. I'd lost my grandchild.
19:36As her one-year-old son is taken into the protection of children's services, Kylie, too, is devastated.
19:45Despite the heartbreaking loss of her child, Kylie still can't give up on Sinclair.
19:52After the baby was taken away, Mark and Kylie still stayed together.
20:02Even after Kylie loses access to her child when the child is taken into care, that ironically must bring her
20:11closer to Sinclair because she feels even more worthless.
20:16She feels even more abandoned and therefore will cling on to Sinclair in a way that she hadn't previously clung
20:24on to because it becomes more intensified.
20:27She's bereaved, I would suggest. She's feeling lonely, abandoned and worthless.
20:37And Sinclair's behaviour is becoming increasingly volatile.
20:42He's arrested for violent offences and burglary and spends time in and out of prison and mental health hospitals.
20:51He always comes back to Kylie.
20:57While Mark can be this callous, violent individual, I have no doubt of his love for Kylie and the way
21:07that they simply couldn't stay away from each other rings absolutely true to me.
21:14There's a kind of till death do us part quality to their initial relationship.
21:22I mean, I think we even have Mark saying at some point, if you try to leave me, I'll kill
21:26you.
21:27Just totally bringing together the two parts of his personality, the passionate and the violent, in that one sentence you
21:34get Mark.
21:39By 2010, still living in Newbury, their relationship is marked by periods where, if Sinclair isn't in prison or hospital,
21:49he simply goes AWOL.
21:51Kylie used to try and ring him. Sometimes he would change his phone number.
22:00The only time Kylie would ever hear from Mark is if he would ring her.
22:08But then Mark would just come back. It's like nothing could happen.
22:20In this course of their 12 year relationship, they were on and off.
22:25And Mark had another child elsewhere.
22:28He has an affair and gets someone else pregnant.
22:33She took it really badly.
22:34And obviously he promised her that he would never have another child for anyone else.
22:39After everything they've been through, Kylie is devastated.
22:43But then she becomes pregnant by him again.
22:47When Kylie told me that she was pregnant with her second child, I was excited for her.
22:55But I was always scared that this baby could go the same way as the first baby.
23:09Anxious over the possibility of losing her second baby, Kylie decides to keep the child away from Sinclair.
23:17She seeks safety and enters a women's refuge.
23:20She went to a mother and baby house and whatever Kylie did with the baby, they used to write it
23:30down.
23:33So that social services knew that she was being a good mum.
23:41Over the course of around 10 months, Kylie develops a sense of independence with her child.
23:49However, in July 2012, Sinclair tracks down the refuge where Kylie is staying.
23:56He assaults her and is sentenced to 22 weeks in prison.
24:01There's no little chance they'll reconcile.
24:05Kylie had said so many times that she would leave him.
24:12But it never happened.
24:17Half-sister Tara is certain Kylie has left Sinclair for good.
24:22She even hears her make a solemn promise to their father on his deathbed.
24:29I had a phone call from my other sister, Rebecca, to say that my dad was down at the hospital
24:38really poorly with ammonia.
24:41Dad absolutely hated Mark.
24:44The only reason why he was civil was because he was with Kylie.
24:48Kylie promised our dad that she would never get back with Mark.
24:57And that's when she promised that she'd leave him.
25:01But then the family feels certain Kylie has found strength through her second son away from Sinclair for good.
25:10But then...
25:11Kylie used to secretly meet Mark where she lived.
25:16And social services found out.
25:20And because she'd done that, that's why they took the baby.
25:27Kylie's child is taken into care.
25:30Ironically, what that does is make her even more dependent on Sinclair.
25:36And so that puts even greater control in the hands of Sinclair.
25:42Because without Sinclair, Kylie has nothing.
25:55When authorities in Berkshire discover Kylie has been meeting Sinclair in secret,
26:01they have no option but to offer protection to her second child.
26:10It just breaks my heart.
26:16I felt angry.
26:18I was annoyed.
26:20Because I knew...
26:26..that she would always choose Mark.
26:34I messaged her and I said, look, you made Dad a promise.
26:37And she said, I know I did.
26:38But I can't...
26:40I've...
26:41That's when she said about the bond and he's only part of her children.
26:45In fact, he probably made himself feel like the victim of all of this.
26:50You know, he lost his two children with Tara.
26:53He's now lost his two children with Kylie.
26:56Kylie's had her children taken from her.
26:58You know, is she a bad mother?
27:00Is this punishment for her, for her past behaviours, if you like?
27:10So, in 2012, Mark and Kylie actually moved out of the area.
27:16Now, one might think, well, that's an opportunity to start over again.
27:19But when I read something like that, I'm immediately thinking,
27:23this is quite risky because they're moving from one police area
27:26to a completely different police area, another local authority area.
27:30So, all these partners aren't going to be aware of the history of Mark and Kylie.
27:35And so, have they gone somewhere else to actually almost start that cycle of violence again,
27:41where they're undetected, until such time that, you know, the police are notified?
27:46By 2017, there's clear evidence that Sinclair's cycle of violence
27:52is becoming even more brazen.
27:55There was this particularly nasty incident where he chased his mother
27:58and a police officer with a meat cleaver.
28:01And it's no surprise that when it came to a review of his risk,
28:06he was deemed high risk.
28:11And for me, that shows that, you know, his pattern and offending the behaviour
28:15is just getting worse and worse and worse.
28:17But obviously, this then makes it a really high-risk situation for Kylie,
28:21who's in that relationship and, on a number of occasions,
28:24has been the sole victim of his violence.
28:27With Sinclair in a secure unit, Kylie relocates multiple times,
28:33first to an Oxford refuge, then back to Newbury.
28:37Yet the cycle repeats immediately upon his release, and they reunite.
28:42They go to live with her mother, Teresa,
28:45who quickly notices Sinclair's increasingly strange behaviour.
28:55When Mark used to live at my house, he used to come into my bedroom at night
29:03and just look at me and watch me sleeping, which I thought was a bit strange.
29:12Sinclair's mental health issues worsen, and they are exacerbated by his drug use.
29:19He's now diagnosed with further conditions, including sociopathy.
29:24And then he sells something precious of Kylie's to a local pub landlord
29:29so as to get money to buy drugs.
29:32There will have been umpteen examples of his callousness in their relationship.
29:39We know, for example, that he sold Kylie's puppy in order to get money for drugs.
29:46That absolutely sums up the disocial personality disorder characteristics that Mark had.
29:53Sinclair strives to convince Kylie his crimes are her fault.
29:58But Kylie remains trapped, unable to leave Mark without proper support.
30:08In June 2018, authorities in Berkshire grow so concerned for her safety
30:14that they step in and initiate a MARAC.
30:18The MARAC is a multi-agency risk assessment conference
30:22and is chaired by an independent person
30:25and a number of partners are invited to that meeting,
30:28which would include the police.
30:29It may involve probation, housing, local authority, health.
30:33And the idea is that those partners share information
30:37that they have on that particular family.
30:39They identify what those risks are.
30:42It may be that probation can review licence conditions of an individual.
30:46It might be that police can do some more monitoring around that
30:49or flag the address that if there are any domestic incidents,
30:51police will respond to urgently.
30:53And so, as I say, the whole idea is to get this holistic approach
30:56on this family to try and problem solve
30:58and actually try and stop the violence happening in the first place.
31:03Authorities contact Kylie's local medical practice
31:06and ask them to encourage her to engage with domestic abuse services.
31:13Kylie doesn't attend.
31:15But around this time, she decides she and Mark should live separately.
31:21Living separately from him, she's still in a relationship with him.
31:25And some people might think that's a little bit strange.
31:28What she's probably doing is she's removing herself
31:30from the risk of day-to-day violence and controlling behaviour,
31:34that she's keeping him happy to a certain extent
31:38and that she is still in a relationship.
31:40She was saying that she just, she'd had enough
31:44and didn't want to be with him no more.
31:47We know that the most dangerous time for the victim of domestic abuse
31:52is when she or indeed he decides that they're going to do something
31:58about the abuse they're experiencing
32:00by creating space within the relationship or indeed leaving.
32:06That's the time at which the threat from the abuser becomes most acute
32:13because the abuser sees this as a loss of control
32:18and he will try to reassert his control to prevent that space in the relationship
32:24or to indeed to prevent the victim from leaving the, the home itself.
32:31And what he might do in that situation is use more violence
32:35and indeed on some occasions use lethal violence.
32:45Teresa is invited to Kylie's new flat in the village of Thiel in West Berkshire to have dinner.
32:52Mark is also there.
32:55I went round there that evening.
32:59We had dinner. We were laughing and joking around.
33:03It was like a normal day.
33:06Teresa sees no sign that Kylie plans to end the relationship permanently.
33:12Even if she is, Kylie has good reason to hide it.
33:17Mark said to her, if you leave me, I'll kill you.
33:20I think he, he was almost, in saying this, I think he was almost trying to warn her
33:27that that is, that is who he is.
33:33Tied to a man who'd rather she died than leave him, Sinclair hurts Kylie again.
33:46We don't know exactly what went on and what led up to this,
33:50but there was clearly a violent altercation which resulted in Mark strangling Kylie
33:54to the point of unconsciousness.
33:57It was an act of extreme violence after Mark rendered Kylie unconscious through strangulation.
34:06He stabbed her in the neck first and then the heart.
34:10So clearly, via an act, he knew what he was doing.
34:15Even though maybe a red mist had descended on him, he knew what he needed to do to render the
34:24result that happened.
34:28There are two different types of injuries, if you like.
34:31There are the stab wounds, which are violent and very personalised.
34:35And then you've got the strangulation as well.
34:38And this, for me, demonstrates a real anger and hatred towards that individual.
34:45People get the impression from watching film or TV drama that strangulation is quite quick.
34:54It can happen literally in seconds.
34:57But if you're going to kill someone through manual strangulation,
35:00it will take three, perhaps even four minutes.
35:04The person can lose consciousness more quickly, but they won't actually be dead.
35:08And all the time that the perpetrator is strangling, he is literally looking into the face of his victim,
35:18watching life drain away.
35:21That gives them the ultimate form of power and control.
35:27All of the warnings, all of the interventions, all of Kylie's fears had proven to be true.
35:46After strangling, stabbing and ultimately killing Kylie, Sinclair does something out of character.
35:54Mark had brutally killed Kylie and then coldly called the police to say exactly what he'd done.
36:02It's as if the murder is a momentary aberration to his general personality.
36:12It's indicative of the way that his personality would have seemed to oscillate between this warm individual
36:22and this person who could be so callous and violent.
36:26Whether Sinclair is calling 999 through genuine guilt or to mitigate his actions,
36:33police quickly arrest him.
36:35They then break the devastating news to her family.
36:39The police came to my house at quarter to five in the morning and said that I need to sit
36:52down,
36:53that something has happened to my daughter Kylie.
37:00Of course, I didn't believe it.
37:03I just sat like I was in another world.
37:10I started to cry.
37:15I couldn't believe what I was hearing.
37:18I had a phone call to ask me if I'd heard about my sister.
37:24And obviously, you'd been, what do you mean, type thing.
37:30And I was like, oh, she's been killed.
37:32And I was like, don't be stupid.
37:34Do you know what I mean?
37:35What?
37:36Don't mess about.
37:37And then obviously I rung my other sister and she confirmed that actually, yeah, she'd been murdered.
37:45Obviously, she'd been stabbed in the neck and straight through her heart.
37:49I just couldn't believe that he'd go that far.
37:52Or that he'd even do that.
37:56Family liaison officers arranged for Tara and Teresa to see her for one last time.
38:06The first time after what happened, I saw my daughter.
38:15In a coffin.
38:18I couldn't believe that that was my daughter lying there.
38:29We went in and she was just led on in the coffin.
38:34Um, and obviously she's as, she's as tiny as Teresa is.
38:39But her face was just blown up.
38:45Where I'm assuming it's where he strangled her.
38:48It was just, it just wasn't nice to look.
38:51She was absolutely beautiful, don't get me wrong.
38:53But it just wasn't nice to see what he had done.
39:05Throughout her entire adult life, Kylie remained loyal to Sinclair.
39:12But could anyone have acted to help her?
39:16He wasn't being managed around his risk.
39:19If he were, then there's certain actions that police and probation could take.
39:23So it could be regular visiting and monitoring of his behaviour.
39:26It could be for him to undertake certain courses to address his behaviour.
39:31But once somebody is not being managed in that process, it's simply just recognising
39:36this particular individual may pose a risk.
39:39And therefore, if a call comes in and his name is linked to that particular call or the address
39:46is linked to that particular call, then the police should treat that call as urgent
39:50and respond immediately and do as much as they can to, to address that risk.
39:55I have no doubt that there were people in the, in the services within the police that,
40:00that saw the warning signs here only too clearly.
40:05But what can they do?
40:06There has to be some degree of voluntary awareness on the part of, of the partner.
40:14There has to be some admission of a problem.
40:18There just wasn't that readiness yet in Kylie to see exactly how much of a risk she was at.
40:25Whether she would have started to comprehend that, we'll never know.
40:36Following Kylie's death, the Thames Valley police state that they aim to establish if there are any areas or lessons
40:44to be learned.
40:45By 2019, authorities intensify their efforts to build the case against St. Clair as they prepare for trial.
40:54He tells the police he didn't mean to kill Kylie, claiming that there were mitigating circumstances.
41:01He tried to state that, um, his actions were down to his personality disorder and that he shouldn't be convicted
41:09of murder,
41:09but he should be convicted of manslaughter.
41:12And this presents, you know, a challenge for the prosecution team.
41:20It can be haunting seeing someone who's capable of that violence and them being not very far away from where
41:28you are sitting.
41:29Of course, there are safe places where there are guards, but you do get a sense of the seriousness of
41:35what's happened.
41:35It can be quite harrowing and haunting to see a person in the dock, a person in the dock who's
41:41capable of such violence.
41:44The trial exposes Sinclair's explosive nature.
41:48He threw a tantrum. He stormed out at one point and started shouting loudly.
41:54We couldn't see him at that point, but we could, we could hear screams.
41:58Throughout the trial, Sinclair continues to claim he didn't mean to kill Kylie.
42:04The defence said that it wasn't a premeditated act.
42:08However, it was an act where Mark Sinclair knew the targets they needed, uh, to kill Kylie.
42:18In terms of first strangling her, then stabbing her, um, through the heart and in the neck.
42:24They look at the previous convictions of Mark as well.
42:27Obviously, um, doctors would be involved to assess him around his personality disorder.
42:32But we know lots of people have personality disorders in this country, but they don't go around strangling and stabbing
42:39people.
42:41Of course, Sinclair is going to try and weaponise the fact that he's diagnosed as having an anti-social personality
42:49disorder.
42:50He wants to try and create a narrative which sees him as being less culpable for killing Kylie,
42:57and therefore mitigate the charge down from murder to manslaughter.
43:03But this is really just another form of manipulation.
43:07On the 12th of March, 2019, after three hours of deliberation, the jury returns a verdict.
43:16Mark was convicted of the murder of Kylie, and he was sentenced to life imprisonment with a minimum term of
43:2221 years.
43:23As soon as they said that, um, the verdict had come back murder and not manslaughter, the relief was just
43:32unreal.
43:34Because it just felt like, to me, yes, he got life, but minimum 21 years, that's still not enough to
43:42me.
43:42Nothing will ever be enough, do you know what I mean?
43:45Um, but to hear that he, the verdict of murder, it was just like a massive relief, and it was
43:52just like, we got what we wanted.
43:57At sentencing, Sinclair makes one final request.
44:01Mark said to the judge, please, can I say something?
44:10And the judge said, yes, you can, Mark, as long as you're not abusive.
44:19Mark said to me, he said, Teresa, can you hear me?
44:24I just totally blanked him.
44:28And he said, he was sorry for what he'd done.
44:38And he never planned it.
44:41The judge was clear.
44:43Sinclair was entirely responsible for his actions.
44:48The judge in the case said, Kylie wasn't able to remove herself from a very dangerous person and a very
44:57dangerous situation.
44:59And he said, um, for the family to not be themselves up over what had happened, um, because he, he
45:07sort of said that it was, in a way, unavoidable.
45:09Um, and they shouldn't, uh, take, take shame in what happened, uh, because there was, there was something binding them.
45:19Um, and, but sadly that did prove, prove fatal.
45:25Sinclair was the one responsible for this ultimate act of violence and for all the years of pain that Kylie
45:33suffered.
45:34But today, her family focus is on honoring her memory with love and affection.
45:42I miss the fun we had.
45:48The laughs we had.
45:54Even the arguments we had.
45:58But we still had a love, mother and daughter.
46:03We had a love, mother and daughter.
46:11Who was born?
46:22But we had a love.
46:24And we were born.
46:24We had a love.
46:25Our love.
