Bailey Gwynne died of a knife wound to the heart at Cults Academy, in Aberdeen
A teenager has been found guilty of the culpable homicide of 16-year-old Bailey Gwynne, who was stabbed at a Scottish school following a row about a biscuit.
Bailey Gwynne died of a knife wound to the heart at Cults Academy, in Aberdeen, on 28 October last year.
The 16-year-old attacker, who cannot be named for legal reasons, was convicted of culpable homicide after a jury ruled against a charge of murder.
There were audible sobs as the verdict was returned after just one hour and 40 minutes of deliberation.
A five-day trial heard how the stabbing took place during the lunch break at one of Scotland's top performing schools.
In a police interview, the killer said Bailey had refused to give another pupil a biscuit and told him: "You don't want to get any fatter."
The killer then replied: "Just like your Mum."
He claimed Bailey then came towards him with a clenched fist.
"I saw he was quite angry. I pulled out the knife, opened it up and tried to scare him off ... he got in the way and it stabbed him."
The knife was 8.5cm and penetrated his heart.
The 16-year-old admitted killing him but denied the charge of murder.
During the police interview, he was asked why he carried a knife. The boy replied: "I've never fitted in so I was just trying to act cool, act confident, act tough, but I wasn't."
He told police he had bought the knife for £40 from Amazon "because they don't check if you're 18 or not".
Forensic analysis of a laptop he used also revealed internet searches for:
The computer analysis also revealed a YouTube video entitled: "14 year-old Bronx student stabs bully to death outside school."
Judge Lady Stacey said the teenager would be held in custody until sentencing on 1 April.
Detective Superintendent David McLaren said: "I'd like to pay tribute to Bailey's family. Today won't bring their son back, the pain of not having Bailey around will last for a very long time.
"Throughout their ordeal they have conducted themselves with the utmost dignity and are a credit to themselves as a family."
