Mother of Confessed Norway Killer Says He Has Lied The mother of Anders Behring Breivik - the man who has confessed to killing 77 people in Norway last summer - claims that as much as half of the information her son has told police is fabricated. The statements from Breivik's mother were read out in court Thursday as psychiatrists presented a 239-page report about the 33-year old extremist's mental health. Breivik's mother isn't appearing at his trial because of health-related reasons, and has not been named due to Norwegian privacy rules. She described how Breivik transformed from a caring son into an aggressive and secretive loner. She also said that "half of what he's told police is a lie" - including exaggerating both his travels and education.
