Violent death: Leah Whittle, 42, was stabbed to death at her house by her teenage son Kieren Smith. He will be sentenced tomorrow
A 17-year-old youth has been found guilty of the murder of his mother who he stabbed to death after losing his temper.
Kieren Smith killed 42-year-old Leah Whittle at her home in Benville Road, Weymouth, Dorset, on July 21.
A jury found him guilty of murder at Winchester Crown Court today following an eight-day trial.
Smith is due to be sentenced at the same court tomorrow.
Smith inflicted knife wounds across her head, back and front in the two bedroom flat they shared, jurors were told.
The teenager, who has ‘an interest in knives’, fled the flat in the early hours, climbing out of his first floor bedroom window and down a drainpipe.
Following the conviction, Detective Inspector Marcus Hester, of Dorset Police, said: 'This case involved a particularly horrific and sustained attack on a woman who was unable to defend herself.
'This is a very tragic case where a young man, through his own violent actions, has killed his mother. He now has to face the consequences of these actions as well as to live with the loss of his mother.'
The trial heard that Smith repeatedly attacked his mother in the flat they shared.
Richard Smith QC, prosecuting, told the jury that the defendant, who was 16 at the time, had an interest in knives and had a temper but he said the reason for the alleged murder would never be known.
Smith had denied the killing and said that men came down from Doncaster in Yorkshire to execute his mother because his brother had got into trouble over a drug debt.
He told friends and the police that he had seen the man or men attack his mother through a bathroom door and when they had left he had bolted the door, taken some money from his mother’s purse and escaped through a window and down a drainpipe.
Mr Smith told the jury that the defendant had spoken to a girlfriend in the hours before his mother was murdered to say she only had a couple of days to live because of the problems over the drug debt.
But Mr Smith alleged that this was just 'setting a scene for some sort of attack on his mother' and that the teenager had either formed a murderous intent or the bravado of the conversation had spurred him on to commit murder because he was 'brooding' over something that had happened between them.
Smith told friends of his 'escape' when he met up with them shortly before 3am, but they did not call the police or an ambulance. In an earlier phone call, at around 10pm that evening, Smith had told a
female friend in that group his mum would be executed and had 'days to
Experts believe Ms Whittle was 'immobilised' early on in a horrific killing at her own son’s hands. A blade wielded by Smith severed her spinal cord, a post mortem of her bloodstained body revealed.

Smith then took money from his mother’s handbag, changed his trousers
and left through the window.
He told his three friends – all girls – that cuts on his hands were from scaling down the drainpipe.
