A 16-year-old boy murdered his mother by stabbing her 94 times, immobilising her early on in the attack by severing her spinal cord, a court heard today.
The teenager, who admits having 'an interest in knives', then claimed Leah Whittle had been killed at their home in Weymouth, Dorset, by a gang of 'mystery men from Yorkshire'.
He inflicted knife wounds across her head, back and front in the two bedroom flat, stabbing her with at least one knife in an attack so sudden she had 'little chance' to defend herself, jurors were told.
The teenager then fled the flat in the early hours, climbing out of his first floor bedroom window and down a drainpipe. He went to visit friends, feeding them an elaborate cover story that he had seen a gang of 'mystery men' from the north of England kill his mother, Winchester Crown Court heard.
Divorced mother-of-three Ms Whittle, 42, was found slumped against the hallway wall.
Prosecutor Richard Smith said the teenager claimed he had watched through a bathroom doorway as other people stabbed his mother to death.
Mr Smith said: 'He described to friends how he had gone into the bathroom and from there was alerted by a noise to something happening outside.
'The implication is that men had entered the flat and were trying to kill his own mother about a foot away from him. 'He said he watched through the ajar door of the bathroom as "they" were stabbing his mother. And at some stage "they" tried to knife him.'
The youngster told friends of his 'escape' when he met up with them shortly before 3am, Mr Smith said. They did not call the police or an ambulance.
In an earlier phone call, at around 10pm that evening, the boy had told a female friend in that group his mother would be executed and had 'days to live', Mr Smith said.
Mr Smith said: 'His brother had got himself into some sort of trouble with a drug debt or the like. 'The boy announced that his mum had only got a couple of days to live.
The friend was left with the impression that his mum's life was at immediate risk.
Mr Smith added: 'Exactly why it was that the defendant decided upon such a dreadful and genuinely tragic course of events perhaps will never be known.
'It may well be that during the course of that night he had become angry at something she had said or done. He says for himself that he has a temper and perhaps that and his interest in knives came together and he took his mother's life.'
