A man who shot a 15-year-old boy in a children’s play area in west London has been jailed for 35 years.
Rene Graham was killed at Emslie Horniman's Pleasance Park in Ladbroke Grove in July 2024 during a family music festival.
Aderahman Boumzough, 25, was sentenced at Woolwich Crown Court on Friday after being found guilty of his murder and the attempted murder of another man.
Judge Simon James called Mr Boumzough "callous and cold-blooded" in his sentencing remarks.
CCTV footage showed Mr Boumzough calmly approaching the children's play area before firing a single shot, with further footage showing him chasing and attempting to shoot a second man before the gun jammed and he fled.
His phone contained a video of him appearing to rap about the jamming, saying: "Don't you hate it when your ting jams? I was prepared to take soul, but Allah had a different plan."
The judge said that Rene was just 15 and "should have had his whole life to realise his dreams and aspirations", and that it was "impossible not to be moved" by his family's attempt to describe their grief.
He added: "I can do no more than echo Rene's mother's words that no mother should ever have to stand in a court and speak about the violent death of her son.
"Her and the rest of Rene's family's heartbreak, shock, anger, and the emotional pain of being robbed of the opportunity of seeing Rene grow into a man, were caused by your callous and cold-blooded conduct in gunning down and killing an unarmed and defenceless teenager in what amounted to a premeditated public execution."
He said that Mr Boumzough failed to provide an explanation or motive for "such extreme and gratuitous public violence", nor demonstrate "even a flicker of remorse".
Det Ch Insp Alison Foxwell from the Metropolitan Police said after last week's verdicts: "While only a small number of people came forward, I would like to thank those individuals who provided statements and supported the investigation, including attending court, who refused to allow a dangerous individual such as Boumzough to live amongst them."
