Connor Tremble stabbing: Murder accused in 'fairy tale world'
A man charged with the murder of his ex-girlfriend's partner was in a "fairy tale world" on the day the killing took place, a court has heard.
Connor Tremble, 17, from Oxford, was stabbed on Fairacres Road in the city on 13 February. He died in hospital two days later.
Will Blencowe, 21, of Oxford Road in Banbury, denies murder.
He remembered stabbing Mr Tremble but told Oxford Crown Court he had not meant to kill him.
The court heard Mr Blencowe, who admitted suffering from paranoia, had a history of self-harm and had been feeling suicidal in the days leading up to Mr Tremble's death.
He said he had told his support worker he was missing his ex-girlfriend, who was then dating Mr Tremble.
The defendant claimed he had visited the teenager's house to buy heroin in order to commit suicide.
He described how the victim was holding a knife when he arrived at his flat. Mr Blencowe told jurors the pair struggled and he remembered stabbing Mr Tremble in the back before running off.
The court was told he had felt as if he was not in control of his own body and described the events as "like being in a fairy tale world where nothing was real".
When asked if he meant to kill him he replied: "No, I never wanted to fight Connor, I'm sorry about what happened that day".
Two other men are also on trial in connection with Connor's death.
Grant Clemens, 24, of Stockwells, Moreton-in-Marsh, Gloucestershire, and Bradley Jones, 21, of Chipping Norton, both deny perverting the course of justice.
The trial continues.
