A 17-year-old boy in Britain was Tuesday found guilty of stabbing his mother 94 times after he lost his temper.
Kieren Smith killed 42-year-old Leah Whittle at her home in Weymouth, Dorset, July 21, the Daily Mail reported.
A jury at Winchester Crown Court found him guilty of murder. He will be sentenced Wednesday.
Smith inflicted knife wounds across his mother's head, back and front in the two bedroom flat they shared, the court was told.
He then fled the flat, climbing out of his first floor bedroom window and down a drainpipe.
Smith has denied the killing and said that some men came down from Doncaster in Yorkshire to execute his mother because his brother had got into trouble over a drug debt.
He told police he saw the men attack his mother, and when they left he bolted the door, took some money from his mother's purse and escaped.
A blade wielded by Smith severed the woman's spinal cord, a post mortem of her bloodstained body revealed.
The murder weapons have never been recovered.
The court heard that the woman's relationship with her son was often less than harmonious but the teenager told police the pair were close.
