A teenager has been found guilty of the murder of London schoolboy Jaden Moodie.
A jury at the Old Bailey found 19-year-old Ayoub Majdouline had killed the 14-year-old in a gang related murder.
Jaden was knocked from his moped and stabbed to death in January.
The teenager's murder happened in the Leyton area of north-east London, an area blighted by so-called county lines gangs that are known to exploit children.
The victim's family shouted "yes" in the courtroom as Majdouline was found guilty by a majority of 11 to one. He was also found guilty of possession of a blade.
The jury had deliberated for nine hours and 22 minutes before reaching its verdict.
CCTV footage from the time of his death shows the teenager being knocked from the vehicle before being repeatedly stabbed and then run over.
The vehicle used in the attack was later found abandoned in a quiet cul-de-sac.
Jaden's family said their son made "anyone who met him fell in love with his charm".
During the trial, jurors were told Jaden had been in trouble with police since he was a 13-year-old.
He was handed a youth conditional caution in March last year after police seized an air-powered pistol, a Rambo knife and cannabis during an altercation in Nottingham.
In October last year, Jaden was found with crack cocaine at an address in Bournemouth and the following month admitted appearing in a Snapchat video with an imitation firearm.
The Metropolitan Police, which carried out the investigation into Jaden's death, has said there needs to be greater stigma around carrying a blade on the capital's streets.
Detective Chief Superintendent Richard Tucker said: "Jaden lost his life on the evening of 8 January because there were people on the streets of Leyton, like Majdouline, who were willing to carry a knife. This attitude needs to change."
Parents have 'no sympathy' for 'child killers'
Jaden's parents, Jada Bailey and Julian Moodie, told ITV News they have "no sympathy at all" for those who "butchered" their "defenceless" son.
They said Jaden was visibly "a child" and "petite in body".
They were visibly angry as they described how a 12-inch knife pierced the schoolboy.
"They came a kill him, they knew what they were doing, they're child killers," Jaden's mother said.
His father asked "how can I feel remorse" for the "monsters" who murdered Jaden.
The couple blamed schools and police for not doing enough to prevent gang crime, pointing to the fact Jaden was recruited into criminality at the school gate as part of a so-called county lines operations run by gangs.
What evidence was heard during the trial?
The Old Bailey heard how drug dealer Ayoub Majdouline was one of five youths linked to the Mali Boys. The gang drove around east London in a stolen Mercedes looking for members of rival gang the Beaumont Crew to attack.
When they came across Jaden Moodie, who was out dealing drugs on a scooter for the Beaumont Crew, they crashed into him and "butchered" him as he lay seriously hurt and defenceless on the ground.
CCTV footage was played in court of Jaden being catapulted over the car's bonnet then subjected to a frenzied attack on the evening of January 8.
Jaden suffered nine stab wounds and bled to death in the road as the attackers ran back to the car and sped off, the court heard.
They then discarded a knife and a pair of yellow rubber gloves, which were recovered from a drain the next day. Detectives also found burnt clothes and items linked the the defendant in a nearby church yard.
Jaden's blood and the defendant's DNA were found on both the knife and one of the gloves, jurors were told.
The day before, Majdouline was caught on CCTV at a Travelodge hotel in Walthamstow, with distinctive Nike Air Max trainers he was wearing during the knife attack on Jaden.
Majdouline, from Wembley, north-west London, admitted dealing drugs for the Mali Boys but denied being present during the fatal attack. The court heard efforts are continuing to identify the other attackers by their DNA.
Prosecutor Oliver Glasgow QC said: "14 seconds was all it took - Jaden did not stand a chance."
Judge Richard Marks QC adjourned sentencing of Majdouline until next Wednesday.
