Killer neighbour stabbed my fiance 17 times before attacking me after bitter two-year feud that began with row over our bins – he robbed my children of their father for nothing

A woman said that her killer neighbour stabbed her fiance 17 times before attacking her after a bitter two-year feud that began with a row over their bins. 

Louise Newell’s partner Dean Allsop, 41, was stabbed 17 times by Jamie Crosbie after their son Mikey revved the engine of a motorbike father and son had been working on together in April 2021.

Crosbie was found guilty of murdering father-of-three Dean in Thorpe St Andrew, near Norwich, and was sentenced to 28 years in jail.

Norfolk Police said that Crosbie was also found guilty of the wounding with intent of two women, Louise as well as friend and neighbour Kerryn Johnson, who had come out to help.

Louise has now spoken out about the ordeal, revealing that her neighbour had ‘held a grudge’ against Dean for two years before he ‘took his revenge’.

‘He was evil. He robbed my children of their father for nothing,’ she told the Sun.

This is the moment Jamie Crosbie told police ‘killing people isn’t always a bad thing’ after stabbing his neighbour to death because the man’s son had been revving his motorbike loudly

In 2018, the mother-of-three said she saw her neighbour Crosbie ‘throwing knives at Dean’ and yell at him for touching his bin.

Dean managed to lock himself into the garden while Louise, with their baby in her arms, stood from the window and called the police before Crosbie threw a hammer in her direction but missed and smashed a neighbour’s window.

Minutes later, police arrived and arrested Crosbie. Louise said the incident left her and the neighbours ‘really shaken up’, but she said she was reassured by police that Crosbie ‘would never come near us again’. 

But years later, she was inside the couple’s home when their son Mikey ran in ‘screaming Dad was dead’. 

She said when she ran out of the house, she found her partner ‘in a pool of blood’ while her neighbour Crosbie ‘stood in his front garden, covered in blood, clutching a giant knife’.

Louise, then 43, was screaming and she called 999 while rushing over to her partner, who had stab wounds ‘all over’. 

She told the Sun: ‘Dean’s eyes were closed but he squeezed my hand. I was hysterical. The operator was telling me to stay calm but I looked up and saw Jamie marching towards Dean again.’

The baker said she pleaded with her neighbour to stop the attack while trying to dodge his giant knife, but Crosbie managed to slash her forehead before stabbing her in the neck twice and once in the chest. 

‘In agony, I nearly collapsed. But I told myself if I did, my kids would have no mum left,’ she said, adding that she kept trying to fight him off until another neighbour, Kerryn Johnson, distracted Crosbie long enough for police to arrive.

Officers arrested Crosbie, who was covered in blood, outside his house, with the knifeman telling police: ‘Killing people isn’t always a bad thing.’  

Police released dramatic bodycam footage of his arrest, which showed his reaction to being told that his victim was dead and he was facing a murder charge.

The defendant was found guilty of murdering father-of-three Mr Allsop (above) in Thorpe St Andrew, near Norwich, following a three-week trial, Norfolk Police said

He said: ‘That makes me happy, that’s a good thing, that’s the best news I ever heard.’

The video also shows Crosbie with lots of blood on his hands and a head wound as officers ask him to kneel on the floor. 

After she was rushed to hospital, Louise said that she was constantly watching the door waiting for Dean to be brought in – but her ‘world collapsed’ when an officer told her that her partner had died. 

Louise said that she is ‘relieved’ that Crosbie can’t hurt anyone else now that he is in prison for life.

‘But no time would ever make up for taking Dean away from us. Jamie held a grudge after his first arrest and took revenge,’ she told the Sun. 

While he was found guilty of murdering Dean, Crosbie was cleared of two counts of attempted murder.

Senior investigating officer Detective Chief Inspector Phill Gray, from the Norfolk and Suffolk Major Investigation Team, said: ‘This was a cold-blooded attack by a man intent on causing extreme harm to others.

‘Dean suffered 17 stab wounds to his body, some of which were inflicted when he was lying face-down and motionless.

‘Crosbie’s savage attack didn’t stop there; he stabbed two people who had come to help Dean, one suffering an arterial bleed to her neck.

‘Crosbie is an extremely violent man who has no place in society, and we welcome the jury’s verdict.’

He said the incident had ‘striking similarities’ to a previous altercation in 2018 where Crosbie threatened Dean with a knife and hammer after Dean put some rubbish in his wheelie bin.

Dean, of Primrose Crescent in Thorpe St Andrew, Norfolk, was pronounced dead at the scene at 8.18pm on April 14 in 2021, Norwich Crown Court heard.

In a statement released through police, Louise said: ‘I cannot put into words how this has affected our whole family.

‘My children have lost their hero and I have lost my chosen person – the person I chose to spend my life with. My best friend, soulmate, my first love.

‘Our lives will never be the same without Dean, but we will continue to keep his memory alive.’

Louise and Dean met as teenagers before getting engaged and having three children – Millie, 22, Mikey, 20, and Jacob, eight – together. 

Dean had a passion for motocross and passed this on to Mikey, with his father teaching him how to ride, according to Louise.

Louise said that she will ‘never stop loving’ Dean, adding that she and her children mourn their lost partner and father every day. 

Andrew Jackson, prosecuting, previously said that Dean and his son Mikey were ‘keen motorcyclists’ and ‘occasionally they would tinker with their motorcycles at home’. 

‘The sound of a motorcycle engine in a residential area can occasionally, like many other things, cause some annoyance to other residents and such minor issues between neighbours can be resolved amicably with some give and take on both sides,’ Mr Jackson said.

‘The prosecution case is that on that day the defendant allowed himself to become annoyed by the noise of the motorcycle engines and he was not prepared to deal in any amicable way at all with that issue.’

Mr Jackson said Crosbie stabbed Dean to death then ‘when Mr Allsop’s partner Louise Newell and their friend and neighbour Kerryn Johnson tried to prevent their neighbour from killing Mr Allsop, the defendant attempted to murder those two women by stabbing them as well’.

He said that Ms Newell sustained injuries to her forehead, cheek and chest, and Ms Johnson to her arm and neck.

Mr Jackson said Crosbie stabbed Mr Allsop (pictured here with one of his three children) to death then ‘when Mr Allsop’s partner Louise Newell and their friend and neighbour Kerryn Johnson tried to prevent their neighbour from killing Mr Allsop, the defendant attempted to murder those two women by stabbing them as well’

Mr Jackson said that on the day in question the engine of Mikey’s motorbike ‘didn’t sound very good at all’, so Dean asked friend Aaron Barkshire, a motorcycle mechanic who also lived in the road at the time, to listen to it.

Mr Barkshire listened to the engine of Mikey’s bike by some garages and the engine was running for ‘no more than a couple of minutes then it was switched off’, Mr Jackson said. ‘But that was enough to attract the attention of the defendant.’

He said Crosbie ‘stuck up his middle finger’ at the three men, from a window in his house, swore at them and said he ‘couldn’t hear his television’.

Mr Jackson said Crosbie swore again and told Dean ‘come and get me’, to which Dean did not react but instead began to dial 999.

The prosecutor said Crosbie then came out of his house holding a saw in one hand and a kitchen knife in the other.

‘He then began to chase Mr Allsop,’ said Mr Jackson. ‘At some point Mr Allsop took off and threw his crash helmet at the defendant.’

He said Mikey ran home and returned with a knife to try to ‘protect his father’, and that by the time Mikey returned Dean had been stabbed.

Mr Jackson said Mikey heard his father say ‘he’s killed me’, Mikey ‘began to cry’ and he hit the defendant with the knife. Mikey then ran home to get his mother.

Crosbie broke the saw during the attack on Mr Allsop, Mr Jackson said, and went home to get a second knife.

After Louise ran to the scene, Crosbie lunged at her and Ms Johnson when she came to help her neighbour, before Crosbie walked back to his house.

Mr Jackson said that Crosbie had threatened Dean with a knife in June 2018, almost three years before the fatal attack, after Mr Allsop put some rubbish in his wheelie bin.

‘It seems the bins were about to be collected,’ the prosecutor said. ‘Mr Allsop’s bin was full so he put some rubbish into his neighbour’s bin.

‘That caused the defendant to threaten him with a knife and a saw. ‘The defendant then chased Mr Allsop down the road.’

Mr Jackson said Crosbie also threw a hammer at Mr Allsop’s house, but it missed and went through a neighbour’s bedroom window.

‘He allowed himself to become angry over a relatively trivial matter,’ the barrister said.

Crosbie was brought to court in 2019 and was convicted of possessing a knife and criminal damage over the 2018 incident, but the neighbours continued to live in the street.
