A schizophrenic mother who had no memory of stabbing her five-year-old son to death will spend the rest of her life in a mental hospital.
Emma Jackson, 41, knifed her son Tyler Warmington 13 times in his chest and back as he slept in his bed in Faringdon, Oxfordshire.
His death was only uncovered when he failed to turn up to school and a member of staff went to the family home to discover the horrific scene.
Jackson told police officers he was upstairs sleeping, but they found him covered in blood under a duvet, Oxford Crown Court heard.
She was yesterday sentenced to indefinitely remain at a mental institution after admitting manslaughter by diminished responsibility.

Judge Ian Pringle QC ruled the fatal stabbing of Tyler had been the result of Jackson’s paranoid schizophrenia, after she had stopped taking anti-depressants.
He said: ‘Were it not for the paranoid schizophrenia in this case the offence would never have been near to being committed.
‘Your life sentence is living with the knowledge that you killed your own son.’
The court was told that fears over Tyler’s wellbeing were first raised after staff at his primary school noticed his absence on the morning of March 13 last year.
The following day after Tyler had failed to attend school for two days and attempts to contact his mother had failed, a staff member from the school went to the family home.
Despite there being no answer, movement was noticed behind a set of curtains and the police were called.

When police community support officer Arthur Gunn arrived at the address, Jackson opened the door covered in blood with cuts to her wrists and neck.
When asked where her son Tyler was, she told police he was sleeping upstairs, and was not able to confirm the last time she had checked on him.
When more officers attended they discovered Tyler dead in an upstairs bedroom partially covered by a duvet, with 13 stab wounds on his chest and back.
Prosecutor Alan Blake said that there had been evidence of severe force in the blows.
Jackson repeatedly asked officers at the scene if Tyler was still sleeping, the court heard. She was arrested and then treated at the John Radcliffe Hospital in Oxford.

Mr Blake said: ‘On the tragic facts of this case it was determined that it was appropriate to accept the plea of not guilty to murder but guilty to manslaughter by diminished responsibility.’
Sentencing, Judge Pringle QC accepted statements from three psychiatrists that she was a diagnosed paranoid schizophrenic, which led to the fatal stabbing of her son.
He said: ‘This is a tragic case and the reports I have read from three eminent psychologists have a degree of unanimity about them.
‘It seems at the time of this act you were suffering paranoid schizophrenia.. Your life sentence is living with the knowledge that you have killed your son.’
An independent case review into Tyler’s death is underway.
