A schoolboy has been convicted of murder after a fatal stabbing following a row over payment for drugs.
The boy killed 17-year-old Jamalie Maleek Deacon Matthew from Brent after they clashed over a cannabis deal.
Jamalie was with a friend who was selling the drugs to the defendant who refused to pay after taking several bags, Harrow Crown Court heard.
The group, who met in Northwick Park, argued and then the killer pulled a knife and stabbed the victim in the abdomen and shin.
The killer, who was 16 at the time, escaped but detectives found a discarded school ID card and phone that led them to him following the incident in November.
Detectives also found evidence of him boasting to friends that he planned to rob Jamalie’s friend.
The killer had already pleaded guilty to possession of a pointed and bladed article at the start of the trial.
He will be sentenced at the same court on Thursday, 29 July.
Detective Inspector Harbir Kooner said: “This was a needless and tragic killing of a young boy. A terrible loss of life over an argument that should never have taken place.
“I would like to thank the officers who worked tirelessly to get justice for Jamalie and his family. It was the fast time work of the team that lead to the subject handing himself in and identifying him at the scene which was fundamental to the case. No family should have to go through what Jamalie’s have and my thoughts continue to be with them as this case comes to a close.”
