Stabbed Willesden schoolboy Quamari Barnes identified his alleged killer in his dying words

Quamari Serunkuma-Barnes told medical staff the name of his alleged killer after he was chased and knifed to death outside his school, The Old Bailey heard

The popular 15-year-old was ambushed in a “deliberate and planned” attack as he left the Capital City Academy, in Doyle Gardens, Willesden, at around 3.22pm on Janurary 23, the Old Bailey heard.

One witness, an 11-year-old pupil, told the court how Quamari “shouted ‘stop it, I’m sorry’” as he ran for his life, dodging through cars to get away.

But he was caught and stabbed to death by his 15-year-old attacker in front of dozens of terrified schoolchildren, jurors heard.

Quamari, described as a “shining star” by family, was taken to hospital where he told a nurse that he recognised the face of the knifeman and gave his first name.

Doctors initially thought he would survive, but four hours later he died after suffering internal bleeding and a cardiac arrest.

The accused, who cannot be named for legal reasons, was also recognised by a schoolgirl witness.

Prosecutor Sally O’Neill said the motive for the stabbing ‘may not ever be known’ but told jurors it could have something to do with a row on Instagram Live.

The prosecutor said: “It was a deliberate and planned attack on a defenceless schoolboy.”

Both Quamari and his alleged killer followed each other on social media and attended the same Willesden youth club, the Roundwood Youth Centre, in Longstone Avenue, the court heard.

A 13-year-old schoolgirl, who also witnessed the attack, described Quamari as “singing really loudly,” as he left school.

“Then I saw someone go from behind him, he started chasing him back to the school gates,” she said.

Witnesses described the attacker as black, skinny and wearing dark clothing with a mask covering their face.

The suspect denies murder and the trial continues.
