A TEENAGER from Doncaster who spent two years alone in his room, watching DVDs, murdered his mother after becoming fascinated with knives.
Kieren Smith, aged 17, stabbed 42-year-old Leah Whittle 94 times at her home in Weymouth, Dorset, where they had settled after moving away from Doncaster when her marriage broke down.
Sentencing Smith to life imprisonment, after he was found guilty by a jury after a trial at Winchester Crown Court, Judge Guy Boney told him he would serve at least 15 years before he could be considered for parole. He said: “You have been convicted of a deeply shocking and really utterly dreadful offence - that of killing your own mother in as brutal a way as can be imagined.
“You have cut short by many years the life of the very person who gave you life in the first place, and expressing your crime in that way tells everyone the true horror of what you did.”
The eight-day trial heard Smith attacked his mother on July 21 in the flat they shared on Benville Road, before he lied to police that she had been killed by drug dealers.
The court heard Smith had been expelled from school at the age of 14 and had spent the last two years alone in his room, watching DVDs.
Judge Boney said: “Your life revolved around watching DVDs alone in your room with an absence of emotional engagement.
“It is from that diet of constant DVDs that your fascination of knives came.”
Nicholas Haggan QC, defending, said Smith’s motive for murder was unknown.
He said: “It’s always difficult to give an explanation and in this particular case it’s impossible.
“One will never know why the defendant did what he did. This is not an ordinary case. We accept it’s very unusual for a young man to kill his mother.”
Smith denied the killing, claiming men came from Doncaster to execute his mother because his brother had got into trouble over a drug debt.
