One of the suspects in a Canadian bomb plot is a former drug user with a history of violence, a self-styled "Muslim Punk" who also wrote songs about his love for Satan. Descriptions of John Nuttall by four people who knew him, combined with court records and his own postings online, portray a sometimes troubled man on the margins of society. Police have charged Nuttall and companion Amanda Korody with trying to set off three home-made pressure cooker bombs in a crowd celebrating the July 1 Canada Day holiday in Victoria, the capital of the Pacific province of British Columbia.
