A Harrow man has been convicted of killing his neighbour in a frenzied knife attack, following a nine-day trial.

Trevor Gibbon, 48, of Windsor Crescent, appeared at the Old Bailey on Thursday (June 25) and was found guilty of the murder of Alison Morrison.

According to a Met Police statement, the court heard Alison and her family had moved next door to Gibbon in 2011 and he clashed with them immediately.

The complaints Gibbon had against the family were so much that it affected Alison and her husbands' health, police said.

Police became involved in March 2014, presenting Gibbon with an acceptable behaviour contract that he refused to sign. On December 17, Gibbon pleaded guilty to harassment.

The next morning, however, Gibbon armed himself with two knives, visiting Alison's route to work, Alexandra Avenue, police added.

At 7.45am on December 18, Gibbon stabbed Alison over 30 times in a frenzied attack, before fleeing the scene in his car. As she was attended to by shocked local residents, Alison was able to name Gibbon as her attacker, a police spokesman added.

Alison was taken to hospital but died from the stab wounds she received to her torso.

Gibbon was stopped and arrested later that morning in Lincolnshire.

Under interview Gibbon answered 'no comment' to questions put to him but, in a prepared statement, claimed his actions where a result of mental illness. He was charged with Alison's murder on December 19.

'Her death has been brought to justice'

Speaking after the verdict, Detective Inspector Jamie Stevenson said: "Despite the overwhelming evidence against him, Trevor Gibbon has put the family of Alison through the ordeal of a trial, during which they have had to re-live the events of that terrible day.

“It is only right that the judge praised the family for their quiet dignity throughout the trial."

Chief Superintendent Simon Ovens, Harrow Borough Commander, said of Alison - who volunteered as Vice Chair of Harrow’s Safer Neighbourhood Board: "Nothing can bring back Alison Morrison or make up for her loss, but the man responsible for her death has been brought to justice.

"My thoughts are with Alison's family and I hope that this, in some way, will help them as they continue to come to terms with the consequences of Gibbon's actions.

"We all continue to miss Alison a great deal but her family and many friends and colleagues in the police will take solace from today's decision by the jury."

Gibbon will be sentenced on Tuesday (June 30) at the Old Bailey.
