The mother of a 14 year old boy, murdered by an internet gamer, said his death had left her "heartbroken and lost."
Computer engineer Lewis Daynes, 19, admitted carrying out the murder after dramatically changing his plea on the day he was due to stand trial at Chelmsford Crown Court.
Barrister Richard Whittam QC told the court it was the prosecution's case that the murder "involved a sexual and sadistic motivation".
Daynes, who's 19, today admitted stabbing to death Breck Bednar, after luring him to his flat.
