A woman who was stabbed 33 times by a neighbour wrote a letter saying he “seemed to enjoy” harassing her just days before the killing, a court heard.
Trevor Gibbon, 48, allegedly armed himself with two knives and ambushed Alison Morrison, 45, as she walked to a train station on her way to work on December 18 last year.
He carried out the ferocious killing the day after he was handed a restraining order having pleaded guilty to harassing Mrs Morrison and her family for years, the Old Bailey trial has heard.
As she lay dying in the street near her home, Mrs Morrison repeatedly named her attacker, telling residents who had flocked to help: "Trevor Gibbon did this to me," the court was told.
He was arrested later that morning 100 miles away in his car in Lincolnshire and charged with murder.
Ahead of the restraining order case, the mother-of-one gave a statement about the abuse she had suffered at his hands, the jury was told today.
Mrs Morrison and her husband Cedric had moved next door to Gibbon in Windsor Crescent, Harrow, north-west London, three-and-a-half years before so they could be near their teenage son's school.
But straight away, Gibbon began complaining about the teenage boy's skateboarding as well as other trivial gripes, to the point where the family felt forced to go to police, the court had heard.
In her hand-written account made days before the killing, Mrs Morrison said: "It got so bad that I could not sleep properly as I felt it would never end."
She said the thing that caused her most anxiety was Gibbon's inability to stop despite the police constantly visiting him.
"He seemed to enjoy it, and whenever the police visited they would change their tactics and escalate what they were doing.
"The constant unending harassment despite police and council intervention was draining.
"Even now I don't believe he knows how to stop doing what he did and fully expect him to start again when he knows things have quietened down," she said.
Gibbon denies murder but has admitted the killing on the basis he was "suffering from an abnormality of mental functioning" which impaired his ability to form rational judgment and exercise self-control.
The trial continues.
