Boy, 14, admits killing foster mom GLASGOW, Scotland, June 23 (UPI) -- A 14-year-old Scottish boy pleaded guilty to the culpable homicide of his foster mother Friday, admitting he stabbed her because she had taken away his Xbox. The teenager, whose identity is being withheld for legal reasons, had faced a murder charge, The Scotsman reported. The High Court in Glasgow postponed sentencing until August to allow time for a report on the boy. The boy was living with Dawn McKenzie, 34, and her husband in Hamilton at the time of the attack in June 2011. Investigators said he stabbed McKenzie in a fit of rage over being grounded and having his Xbox, cellphone and laptop taken away. McKenzie called police and her mother after the boy fled. McKenzie, who died less than 2 hours after the attack, was able to identify the boy was her assailant. Bryan McKenzie said when he left the apartment an hour before the attack everything was peaceful. The boy was picked up nearby by a police officer who found him walking along a road with a cloth wrapped around his hand.
