A teenager is found guilty of fatally stabbing a classmate at an English school.

London.- A jury found guilty this Friday in the Sheffield Criminal Court (northern England) a 15-year-old teenager accused of stabbing to death a classmate of the same age at a school in that English city on February 3rd.

The defendant, whose identity was not made public due to being a minor and who was found guilty of murder and carrying a knife, had admitted to the manslaughter of the victim, identified as Harvey Willgoose, but denied the murder, claiming that he "lost his temper" after being harassed and said he does not remember what happened. The minor brought a 13-centimeter hunting knife to All Saints Catholic school with which he inflicted a fatal stab wound to the heart of his classmate, with whom he had a dispute over another fight between other young people, according to the Crown Prosecution Service in a statement.

That previous confrontation escalated on the social network Snapchat, where they threatened each other.

The school security footage showed the defendant stabbing Willgoose twice, once in the chest and once in the abdomen. Prosecutors maintained that it was a murder and not manslaughter since the defendant had "hidden and deliberately taken the knife to school" and "had previously ignored a friend's request to hand over the weapon that day to avoid doing something stupid".

The sentence will be announced at a later date not specified by the court.
