In August 1993, Vikernes fatally stabbed Mayhem guitarist Euronymous during an altercation at the latter's apartment, and was arrested shortly after. In May 1994, Vikernes was convicted of first-degree murder, church arson and possession of explosives. Vikernes said the killing was self-defense and unsuccessfully argued for the charge to be reduced to voluntary manslaughter. He was sentenced to 21 years in prison, the maximum penalty under Norwegian law. During his incarceration, Vikernes launched the Norwegian Heathen Front, had two books published, and released two ambient albums as Burzum. In 2009, he was released on parole, after which he moved to France with his wife and children, where he has continued to write and make music.
