Three men have been found guilty of murdering teenager Taylor Cox near a school in north London in June 2021.
The 19-year-old, from Barnet, was shot in the head on Hornsey Rise Gardens in Crouch Hill and later died in hospital despite efforts from neighbours to help him.
The shooting took place just 100m away from Hornsey Day Nursery and nearby Ashmount Primary School.
At the time a witness said Mr Cox had been “ambushed” and blasted with at least three rounds in an alley next to the school.
Jaden McGibbon, 22, Robel Michael, 22, and Sichem Mangituka-Mpelo, 22, were found guilty at the Old Bailey on Friday and remanded in custody until their sentencing hearing on December 15.
A fourth person, Dunia Oukili, 22, was convicted of perverting the course of justice. She was McGibbon's girlfriend who booked a hotel room and bought a mobile phone in an attempt to help him avoid being arrested.
Officers found spent ammunition cartridge cases in Oukili’s handbag that was of the same calibre to those used in the shooting, Metropolitan Police said on Saturday.
Detective Chief Inspector Linda Bradley, from the Met's Specialist Crime Command, said: “This was a targeted attack on a young man who should have had the rest of his life ahead of him.
"It saddens me to see so many young lives cut short by violence on the streets of our capital and I hope these convictions, and the loss of freedom the defendants are about to face, serve as a warning to any others who think that conflict of any kind can be resolved with weapons and violence.
"My thoughts are with Taylor’s family. While nothing can bring him back, I hope that today’s guilty verdicts bring them a degree of satisfaction.”
During the investigation detectives trawled through hours of CCTV footage and found images of McGibbon riding a bicycle shortly before the report of shots fired was made to police.
Just before the murder he covered his face with a balaclava, the Met said.
Despite his efforts to avoid capture, McGibbon was arrested on June 12, 2021 and was charged with murder the following day.
Michael was arrested on August 4, 2021 and was subsequently charged with murder. Mangituka-Mpelo was arrested on August 23, 2021 and also charged with murder.
Taylor's father, David Campbell, said: "The whole family are grateful that we come to this conclusion and are thankful for the efforts of the police in all the work they did to convict the defendants. Despite the guilty verdict, it still doesn’t help the pain that knowing we won’t see Taylor again causes us".
