A man has been jailed for at least 28 years after stabbing his neighbor to death over his son’s “annoying” motorbike noise.
Dean Allsop, 41, was stabbed 17 times last year in Primrose Crescent, Norwich, while his partner Louise Newell, among three others, was also stabbed in the attack. The father of three died at the scene.
James Crosbie admitted manslaughter on the grounds of diminished responsibility but denied murder. Crosbie was also found guilty of wounding Mrs Newell and friend and neighbor Kerryn Johnson, who tried to stop the attack, but was acquitted of two counts of attempted murder.
Sentencing at Norwich Crown Court, Judge Anthony Bate told Crosbie: “I consider you a very dangerous man.”
He sentenced Crosbie to life in prison with a minimum term of 28 years, which is the time he must serve behind bars before he can be considered for release.
The defendant stared straight ahead throughout Wednesday’s sentencing hearing and bounced his left knee up and down, showing no reaction as he was led to the cells.
His partner Ms Newell said in a victim impact statement read to the court by prosecutor Andrew Jackson: “I will never forgive Crosbie for what he did to my family.”
She added: “I hope he is never released.”
Crosbie was convicted in 2018 of criminal damage and possession of a knife for an incident when he threatened Mr Allsop with a knife and hammer after Mr Allsop had put some rubbish in his bin, Mr Jackson said.
The Crown Prosecution Service said Crosbie had made threats to his supervising detective to kill Mr Allsop while he was serving a suspended sentence for the 2018 offences.
Jackson said there “can be no dispute” that at the time of the murder, Crosbie was “suffering from a mental disability” described by a psychiatrist as a “delusional disorder”.
He said that “did not extinguish” the defendant’s guilt. Sir. Jackson said Crosbie said he had drunk about a bottle and a half of wine before the killing.
Judge Anthony Bate told Crosbie: “You are aptly described as an isolated man who lives alone.”
In a statement released through police, Newell said she “cannot put into words how this has affected our entire family”.
“My kids have lost their hero and I’ve lost my chosen one — the person I chose to spend my life with,” she said.
“My best friend, soul mate, my first love.
“Our lives will never be the same without Dean, but we will continue to keep his memory alive.”
During the trial, the court heard that Mr Allsop was stabbed several times after his son Mikey revved the engine of a motorcycle they had been working on just after 9am. 20.15 on 14 April.
During the disturbances in Thorpe St. Andrew said the force “some of the stab wounds were inflicted when the victim was face down and motionless” in a “savage attack”.
After sentencing, Detective Chief Inspector Phill Gray said: “This was a cold-blooded attack by a man who intended to cause extreme harm to others.
“Crosbie is an extremely violent man who has no place in society and we welcome the jury’s verdict.”
