A knifeman was today convicted of murder after a court heard he acted out his own horror film with himself in the ‘starring role’ when he stabbed one neighbour to death and tried to kill another in a shocking rampage.

Can Arslan, 52, killed father-of-three Matthew Boorman, 43, some 27 times on the victim’s front lawn in the Gloucestershire village of Walton Cardiff near Tewkesbury, and then sat on his body and lit a cigarette.

He also knifed Mr Boorman’s wife, Sarah, in the leg as she tried to drag him off her husband on October 5 last year, and then forced his way into the home of another man, Peter Marsden, and stabbed him eight times.

Arslan had subjected his neighbours on the new-build development to years of verbal abuse and threats and was on the point of being evicted from his property when he launched his attack. 

Arslan, who has been on trial at Bristol Crown Court, had denied murder, claiming he should be convicted of a lesser charge of manslaughter on the grounds of diminished responsibility. But the jury unanimously convicted him of murder after a day of deliberations.

Before the trial, Arslan had already admitted the attempted murder of Mr Marsden, and causing grievous bodily harm to Mrs Boorman. He also admitted affray. The defendant has been brought to the court from Broadmoor maximum security psychiatric hospital in Berkshire every day – accompanied by six psychiatric nurses.

Flanked by the six nurses today, Arslan, wearing a pink hooded top remained motionless as he was convicted. His wife and stepdaughter wept as the verdict was read out, and he blew kisses to them as he was led away.

Trial judge Mrs Justice Cutts said she wanted a further psychiatric report prepared on him before sentencing, and set a hearing for two months’ time. She told him: ‘I am not going to sentence you today; I am going to sentence you on June 9 when I will have an additional report on you. In the meantime you will remain in Broadmoor.’ 

At the time of the killing, Arslan was the subject of an injunction prohibiting him from threatening or abusing his neighbours, and had been served with a notice of eviction. Small rows over parking and a scratch to a car had escalated to the point where Arslan had repeatedly threatened to attack or kill those living near him.

The murder and subsequent threats and attacks were caught in graphic detail on the neighbourhood’s many CCTV and doorbell cameras installed by anxious residents, and played to the jury during the trial. 

Two forensic psychiatrists agreed Arslan was not psychotic or mentally ill; however, he was diagnosed with a paranoid, unstable and antisocial personality disorder.

The prosecution argued that, although his personality was outside of what is normal, Arslan was fully in control of what he was doing and that he knew the difference between right and wrong.

Arslan’s defence team had said his personality disorder met the condition of ‘abnormality of mental function’ that would reduce the crime from murder to manslaughter.

In her closing speech to the jury yesterday, Kate Brunner QC likened Arslan to The Terminator and cited the words of one of Mr Boorman’s colleagues, who was on the phone to him when Arslan attacked. 

‘She said it was like listening to a ‘totally horrendous horror movie’, and it was a horror movie that was just beginning and this defendant had written the script,’ Ms Brunner said.

‘This was not something that happened to him – it was something he had planned and controlled. It was a horror movie planned out, where he was going to stab his victims to death one by one. 

‘A horror movie where he was going to take a starring role, and end up on the TV.’

Following his arrest, Arslan asked officers if he was on Sky News or the BBC.

Ms Brunner said the defendant had faked a number different potential psychiatric defences, such as being suicidal, hearing voices telling him to kill, and then amnesia of the incident.

He asked the psychiatrist instructed by the defence if her report could get him a lesser sentence. Ms Brunner said that by faking mental illness, Arslan had demonstrated how rational he was.

‘He is a cunning, smart man trying to pull the wool over eyes,’ the prosecutor said.

Howard Godfrey QC, for Arslan, had said the defendant was not trying to ‘wriggle out’ of responsibility for Mr Boorman’s death, but said it was clearly ‘not normal behaviour’.

‘He attacks in broad daylight, when everyone is around and there is CCTV everywhere – is that normal?’ he said.

‘He doesn’t do it at night when someone is out walking their dog and then run away, he doesn’t wear a mask to try and hide who he is; it’s broad daylight, in front of everyone who is around.’

Mr Godfrey went on: ‘After Mr Boorman was dead, he continued stabbing him 27 times, then lights a cigarette and sits on top of Mr Boorman. Does that seem like normal behaviour?

‘He is calm, he is robotic, he is emotionless throughout much of this.’

Mr Godfrey referred to a number of witnesses who described Arslan as having ‘psycho’ or ‘beady’ eyes, or seeming to be ‘amused’ by what he was doing.

He also cited the evidence of forensic psychiatrist Dr Sally Foster, who found ‘impaired mental functioning was a significant contributing factor to the defendant’s acts’.

Mr Godfrey said: ‘In her expert opinion, (Arslan’s personality disorder) did impact his ability to form a rational judgment and it was bad enough to amount to an abnormality of mental function.’ 

During the trial last week on March 31, the court heard that Arslan said the voice of his childhood teddy bear told him to kill – but a forensic psychiatrist said they were ‘sceptical’ of the claim.

Expert forensic psychologist Dr John Sandford told the jury he did not consider Arslan to be mentally ill and that he did not need to be in hospital.

He instead found he had a personality disorder, which he described as applying to people with ‘a personality outside of the normal range’.

Dr Sandford said: ‘Sometimes you can help them but in some cases you can’t because that is just what they are, it’s their character.’

The witness explained that people suffering a psychotic episode or prolonged mental illness will tend to have a ‘package’ of symptoms, including paranoid delusion and auditory and visual hallucinations.

He said people who are hallucinating are often very distracted, will respond to the voices they are hearing and find it hard to differentiate between the person talking to them in real life and the voice.

The first mention of ‘voices’ in Arslan’s medical records came at 7.33pm on the night of the killing, when he told police ‘the voice said to me to ‘kill him”.

In later references to the voice, he said it belonged to his childhood teddy bear. ‘With forensic psychology you have to have a degree of scepticism,’ Dr Sandford said.

He added: ‘When you get a voice on its own you are always very sceptical, but when you get a voice on its own after a serious offence you are even more sceptical.’

Ordinarily, the voices would fit in to the pattern of someone’s delusional beliefs, the witness said.

He cited the example of someone believing the voices in their head to be coming from a microphone planted in their teeth by the KGB.

Dr Sandford said that someone with personality disorder may hold fixed beliefs that are not true, but not in the way someone with a mental disorder may hold paranoid delusions.

He said Arslan ‘believed the UK was fundamentally racist, believed the police were wholly corrupt and believed his neighbours had been unfair to him, and that they were persecuting him’.

Dr Sandford said that Arslan’s beliefs were rooted in reality – his neighbours had taken an injunction out against him preventing him from harassing them and he was facing eviction.

The court heard Arslan had a ‘grandiose’ and narcissistic view of himself, claiming to have wealthy relatives, have gangsters in his family and to have killed 61 people during his military service.

Dr Sandford said that during assessments, Arslan had both claimed not to remember the incident, and also that the violence was justifiable.

‘(The defendant) felt that these people had persecuted him, he felt he was a victim of the eviction notice and the neighbours, and he also saw it as quite reasonable to take the life of another person,’ he said.

Dr Sandford said he did not believe that Arslan had no memory of the event, saying amnesia is usually only caused by a powerful blow to the head or heavy intoxication.

He added that ‘selective amnesia’ – where someone represses a painful incident to the point that they can no longer remember it – is a disputed phenomenon among psychiatrists.

‘It is extremely rare, you never see it in general psychiatric practice, and some say it is so rare it is not real, you only see it in offenders,’ he said.

Dr Sandford said: ‘There is nothing to suggest that this man is mentally ill or disordered in some way, he is doing a series of purposeful acts that are goal directed, his goal is to kill Mr Boorman, and attempt to kill his other neighbour – it is quite clear how he is going about that.

‘He is quite controlled in the way he is stabbing – he is stabbing (the victim), it is not frenzied, he is stabbing him slowly and deliberately in the neck.’

Also last week on March 30, jurors at his murder trial at Bristol Crown Court saw a compilation of video clips taken on the day of Mr Boorman’s killing.

Some of the footage was released by Gloucestershire Police after it was played in court.

It started with off-duty police officer Stephen Wilkinson, who was carrying a piece of wood, following Arslan as he walked towards the rear entrance of neighbour Peter Marsden’s home.

Minutes earlier, Arslan had fatally stabbed Mr Boorman – who had been next-door neighbours with Arslan since 2013 – on his front lawn and was heading to confront Mr Marsden.

Mr Wilkinson was trying to make him drop the knife, telling him, ‘You stand still, now. Don’t you f****** go down there. Put the f****** knife down now. Put it down’.

Arslan forced the gate into Mr Marsden’s garden and the CCTV then showed Mr Marsden wrestling him out of his home – having been stabbed eight times – while Mr Wilkinson hit him with the wood.

Mr Wilkinson could be heard telling Mr Marsden to lock his door, and he left the garden and went back into the street.

Arslan then lit a cigarette and left, where he was again confronted by Mr Wilkinson and other neighbours, who were by this point armed with golf clubs.

The footage ended with Mr Wilkinson again telling Arslan to put the knife down, and the attacker then walked back towards the Boormans’ home. 

Police also released further footage taken from the body-worn cameras of the officers who arrested Arslan.

Arslan, who was lying on the road with his hands cuffed around his back, was heard swearing at police and saying, ‘You’re next mother******, you’re next.’

Arslan added: ‘He’s dead, isn’t he? I warn you, the police, one year. Look it happened. I was special forces, I warned them I was going to murder him, ha, ha, ha.’

As he was placed in a police van, Arslan said: ‘I told the police one year because he was against my son, my wife, ha, ha, ha.’

He then said there was a bounty on the police officers and calls them ‘mother*******’.

One day earlier during the trial on March 29, the court heard that Arslan  stabbed his neighbour to death on the victim’s front lawn before sitting on top of him and lighting a ‘triumphant’ cigarette after the killing.

Mr Boorman, who worked for engineering firm GE Aviation, had just returned from work when Arslan stabbed him.

Mr Boorman’s wife, Sarah, witnessed the entire attack and tried to pull Arslan off her husband, suffering a deep wound to her thigh as a result.

In a recorded police interview, Mrs Boorman said she had unlocked the front door for her husband at around 5pm on the day of the incident, and had seen Arslan cross in front of her kitchen window.

She initially believed Arslan was throwing punches, but then realised he had a knife. The witness mimed the blade being brought down over and over again into her husband’s face and neck.

‘He continued to just stab Matthew like he was an animal,’ she said.

Mrs Boorman said she had screamed at the neighbours to come and help her, and Arslan had swiped at her with the knife.

‘I wish I had hit (Arslan) with something or thrown something or done something to distract him so Matthew had a chance to run,’ she said.

‘Arslan treated Matthew like he was a piece of meat; he sat on top of him and he lit a cigarette as if he was triumphant.

‘Then he threw the cigarette on the floor and got up casually and walked around to the front garden as Matthew lay dying on the floor.’

Describing the defendant’s manner, she said: ‘He was calm, he knew exactly what he was doing, he had waited for Matthew, he had done what he had done to Matthew and he was pleased with what he had done to Matthew.’

She added that her oldest child had seen his father’s bloodied body from the window, adding: ‘He can’t get it out of his head.’

After killing Mr Boorman, Arslan forced his way into the home of Peter Marsden and stabbed him eight times, although Mr Marsden eventually managed to wrestle him out of the property.

He was helped by Mr Wilkinson, an off-duty police officer, who followed Arslan brandishing a piece of wood, trying to force him to drop the knife.

The jury were shown footage of Arslan banging on Mr Marsden’s patio windows with the knife calling ‘come out, come out’, before lighting a cigarette.

The attacker then walked back towards the Boormans’ home, and those administering CPR had to carry Mr Boorman away in case Arslan targeted him again.

Residents armed with golf clubs, bats and planks of wood managed to contain Arslan until police arrived.

Mrs Boorman said: ‘He was threatening everyone and enjoying it, he loved the attention of it – he was saying he was going to murder us.’

Another neighbour, Elizabeth Stock, who is a nurse, noticed that, when police arrived, Arslan’s wife, Louise, was ‘verbally aggressive’ to officers and threw a glass of water at them.

The Boormans and people living nearby had suffered years of abuse from Arslan, and Mrs Boorman said they had not used their back garden for more than a year because of his threats.

He would yell at them that he knew where she and her husband worked, and film the windows of their children’s bedrooms.

On the first day of his trial at Bristol Crown Court on March 28, prosecutor Ms Brunner said there had been a ‘long-running’ dispute between Arslan and his neighbours.

Small rows over parking and a scratch to a car had escalated to the point where Arslan had repeatedly threatened to attack or kill those living near him, and they were trying to have him evicted.

Ms Brunner told the jury there is no dispute that Arslan had killed Mr Boorman, telling them what they must decide is whether it was murder or manslaughter on the grounds of diminished responsibility.

Almost all of the attack on Mr Boorman and Mr Marsden were caught on CCTV and doorbell cameras around the estate.

Mr Boorman had just parked outside his house at about 5.20pm after returning from work, and was still on a conference call when Arslan stabbed him.

The prosecutor said Mrs Boorman had come to open the front door and ‘she initially thought (the defendant) was throwing punches but came to realise he had a knife in his hand and was stabbing her husband’.

Colleagues on the conference call heard Mr Boorman shout ‘what the f*** are you doing?’ and Arslan replying ‘f****** want it’? in a ‘goading’ tone.

Ms Brunner said: ‘The defendant appeared calm, smiling as if he was amused by what he was doing.’

Arslan was heard to say ‘You’ve no idea what this guy put me through’, adding ‘he evicted me’.

A post-mortem examination found Mr Boorman had suffered 27 serious knife injuries, as well as many more superficial cuts.

After leaving Mr Boorman dead or dying on his lawn, Arslan entered Mr Marsden’s home via a side gate, and forced his way into the kitchen where the victim was sitting with his wife.

The victim managed to grapple Arslan out of the property and lock the door, although he sustained eight serious knife wounds in the process.

After his arrest Arslan claimed he had taken an overdose, but medics found that he did not seem to be on any kind of drug. A psychiatric assessment found that he was alert and had no psychotic symptoms, the jury heard.

While in hospital, he was interviewed by police and made comments about stabbing his neighbours, referred to his impending eviction and his life being ruined.

He said he intended to kill a number of people who were bringing legal action against him.

In a second interview, Arslan claimed he could not remember anything.

Ms Brunner said the attack on October 5 had been preceded by years of threats from Arslan to neighbours, including telling the Boormans ‘I’m going to kill you’ and ‘I’m going to put you in the ground’.

He would described the violence he planned to do to them while pretending to be on the phone in his back garden.

In May, Mrs Boorman had made a statement to police setting out a summary of the threats they had received from the defendant.

She said they were worried about being murdered, or that someone was going to be seriously hurt very soon. Arslan, who is Turkish, made counter-allegations, accusing the Boormans of racially abusing him.

The day before the attack, a police officer had telephoned Arslan about the complaint he had made.

‘The defendant swore at the police officer and said he would sort his neighbour out himself, Mr Arslan said he would murder him,’ Ms Brunner said.

After the trial had finished, a spokesman for the Independent Office for Police Conduct told MailOnline today: ‘We are investigating Gloucestershire Constabulary’s actions following a series of reported neighbourhood incidents prior to the death of Matthew Boorman in Walton Cardiff, near Tewkesbury, in October.

‘We are examining what actions police took in response to a number of reports made by neighbours since January last year. Our independent investigation began following a mandatory referral from Gloucestershire Constabulary about prior police contact and force referrals of neighbour complaints. Our investigation is continuing.’
