out. Mother was my biggest fear. I didn't know if the police would let her at me." Woodcock was tried only for the murder of Carole Voyce. On April 11, 1957, after a four-day trial, he was found not guilty by reason of insanity and was sent to the Oak Ridge division of the maximum-security Penetanguishene Mental Health Centre in Penetanguishene, Ontario. Imprisonment While imprisoned, Woodcock was diagnosed as a psychopath. He underwent various forms of psychiatric therapy, including LSD treatments when they were popular in the 1960s. He was also given other personality-breaking drugs: scopolamine, sodium amytal, methedrine and dexamyl. He was subjected to "dyads"—a personality-breaking therapy in which inmates challenged each other's belief systems—which inmates referred to as "The Hundred-Day Hate-In".

During this time, he legally changed his name to David Michael Krueger and rekindled a relationship with Bruce Hamill, an Ottawa killer who had been released from Oak Ridge and was working as a security guard at the Ottawa courthouse. Krueger convinced Hamill an alien brotherhood would solve his problems if he helped kill another Brockville inmate, Dennis Kerr. Murder of Dennis Kerr On July 13, 1991, Bruce Hamill went to a hardware store, bought a plumber's wrench, hatchet, knives and a sleeping bag, then went to the Brockville hospital and signed out the 52-year-old Krueger on his first publicly escorted day pass. Within the first hour of his first unsupervised release in 34 years, Krueger arranged to meet Dennis Kerr in the woods. When Dennis Kerr arrived, Krueger struck him in the head with the
