Boy, 16, Guilty of Attempted Murder After Stabbing Girl at Norfolk School
Boy Who Stabbed Fellow Pupil Faces December Sentencing
Jury Rejects Teenager’s Denial of Intent to Kill
The defendant had admitted wounding a fellow pupil, but jurors had to decide whether he intended to kill her.
A 16-year-old boy has been convicted of attempted murder after stabbing a 15-year-old girl in the back at Thorpe St Andrew School near Norwich. The jury returned its verdict at King’s Lynn Crown Court on 21 October 2026.
The boy, who cannot be identified because of his age, had denied attempting to kill her. He had already admitted wounding with intent and possessing a knife at school.
The Attack on 11 March
The defendant was 15 when the stabbing took place on 11 March. Prosecutor Christopher Paxton KC told the court that he arrived dressed in black, wearing a mask and carrying a kitchen knife.
In her evidence, the girl described initially feeling something like a touch on her shoulder followed by a punch. She did not immediately understand that she had been stabbed. As she tried to open a door, she felt weak and numb, before reaching a classroom and telling a teacher what had happened.
The school went into lockdown and armed police responded. The girl was taken to hospital and discharged the next day. Her survival left a separate question for the trial: what had the defendant intended when he attacked her?
Why Intent Was the Central Issue
Attempted murder requires proof of an intention to kill. An intention to cause serious injury is not enough. That distinction explains why admitting a deliberate wounding does not automatically amount to admitting attempted murder.
The injury and the intention therefore had to be considered separately. A victim can survive an attempt on their life without suffering the worst possible physical injuries. Equally, evidence of a violent assault does not remove the prosecution’s obligation to prove the particular intent required for attempted murder.
In this case, jurors had to consider the boy’s earlier writings alongside what he actually did at school. The dispute concerned the meaning of that evidence, rather than whether he had stabbed the girl.
The Writings Put Before the Jury
Paxton described a preoccupation with killers and killing. He told jurors that police found a handwritten list of names marked as possible victims, along with material setting out an attack at the school.
The prosecution also presented writings expressing hostility towards women and a wish to kill more than one person. These were evidence of the defendant’s stated thoughts and plans; they were not proof that every person mentioned had been attacked.
The relevance of the material was specific. Prosecutors used it to support their case about the purpose behind the stabbing. The jury still had to assess that argument against the circumstances of the offence.
What the Defence Argued
Defence barrister Stephen Rose KC argued that earlier planning did not settle the question of intention at the moment of the attack. He said the defendant had hesitated, used limited force and inflicted a shallow wound before leaving the school.
Rose’s argument was that the boy’s conduct differed from the violent plans recorded in his notes. The defence asked jurors to recognise that a person could change their mind, even after making preparations.
The boy did not give evidence. After three hours and 54 minutes of deliberation, the jury unanimously found him guilty of attempted murder.
Sentencing Will Follow in December
Mr Justice Lickley adjourned the case for a report on the defendant and asked that it address dangerousness. He warned the boy that he would have to consider a lengthy custodial sentence, while leaving the final decision for the sentencing hearing.
That warning is not a sentence already imposed. The boy remains remanded and is due to be sentenced at King’s Lynn Crown Court on 18 December 2026.
