A drug addict who murdered his 83-year-old grandmother in a "brutal and frenzied" attack has been jailed for life at the Old Bailey.
Jack Langlands repeatedly stabbed Doris Langlands in the head at her north London home in April last year.
Jurors heard Langlands, 27, lived with his grandmother and had sponged £30,000 from her for cocaine and alcohol.
He was ordered to serve at least 22 years in jail after jurors rejected his claims voices had told him to kill her.
Mrs Langlands, who was known as Dot, was found in a pool of blood on the kitchen floor of her house in Green Dragon Lane, Winchmore Hill.
