A KILLER has been told he is facing life behind bars after he was found guilty of murdering his sister’s boyfriend.
John Blackburn attacked “best mate” Cole Wilson with a kitchen knife, leaving him with fatal wounds to his head and chest.
The 20-year-old bled to death within minutes in the living room of a house in Sledemere Close, Peterlee, after the attack on September 18.
Blackburn, also 20, denied murder but was convicted by a jury after a trial at Newcastle Crown Court.
The case was adjourned until month but Judge Paul Sloan warned Blackburn he will receive a life sentence.
Judge Sloan said: “There is only one sentence to be passed in your case and that is a sentence of custody for life.
“I am duty bound by Parliament to set a minimum term which you must serve before you can even be considered for release.”
During the trial, Jade Blackburn, 21, wept as she described to jurors how her partner Mr Wilson told her “I love you” and kissed her just moments before he died from the wounds inflicted by her brother.
The court was told Blackburn became involved in a confrontation after Mr Wilson and Miss Blackburn had rowed and he said “you are not going to hit my sister” before he attacked Mr Wilson.
Prosecutor Mark Giuliani told the court Blackburn had warned he was going to stab Mr Wilson before he delivered the fatal wounds at his girlfriend Kim McGuire’s home.
Miss Blackburn told that court that she saw her brother throw what she thought was a punch at her boyfriend of three years but never saw the knife.
Blackburn, of Holywell Avenue, Walker, Newcastle, denied murder throughout the trial.
Detective Superintendent Ken Donnelly, who led the investigation, said after the verdict: “We hope the sentence he receives serves as a warning to others that if they resort to violence, particularly using knives, they will suffer the consequences.”
