The fight that resulted in the tragic death of Cults Academy pupil Bailey Gwynne was started over a biscuit, a court has heard.
The trial over the stabbing that resulted in Bailey’s death started on Tuesday, March 1, and could last for up to five days.
A 16-year-old boy - who cannot be named for legal reasons - stands accused of murdering Bailey.
The accused’s lawyer for the pretrial hearing entered a guilty plea to the reduced allegation of culpable homicide during a hearing at the High Court in Glasgow on Tuesday, February 23, but denied murder.
One witness on the first day of the trial in the High Court in Aberdeen described how “name-calling” over Bailey’s refusal to give a biscuit to another boy in a group of year five pupils escalated into a physical altercation on October 28, 2015.
Jurors were also told that the accused had been previously warned about taking knives into the school.
A witness, also 16 years old, broke down in tears after describing what he saw.
He said that he was friends with both the accused and Bailey - also 16 years old - and then told the court he had been in the corridor with them just before the fight.
The youth described how Bailey and the accused were arguing before it developed into a fight, and that the pair were “pushing and pulling” each other before the accused reached into his left blazer pocket and brandished a knife.
Then the accused “thrust it towards Bailey. It went into Bailey”, he said.
The witness described it as entering the “tummy area”.
However, he added that this did not stop the fight and once the knife was pulled out, “they continued pushing and struggling with each other”.
The Counsel for the accused, Ian Duguid QC, put it to the witness that the altercation began over a biscuit.
The lawyer said: “Unbelievably, the evidence suggests that this all started over a biscuit.”
The court heard that Bailey would not give the accused the snack as he was “too fat”.
It was added that teasing along this theme had been ongoing for weeks before the incident.
Mr Duguid then put it to the witness that the accused retorted by saying Bailey’s mother was fat, resulting in Bailey “lashing out”.
The witness confirmed his statement to the police that Bailey attacked first, and that the accused was “defending himself”.
Also on the first day of the trial, the jurors were shown the four-inch blade that was used against Bailey.
