David Michael Krueger (March 5, 1939 – March 5, 2010), best known by his birth name, Peter Woodcock, was a Canadian serial killer, child rapist and diagnosed psychopath. He gained notoriety for the murders of three young children in Toronto in the late 1950s, as well as for a murder in 1991 on his first day of unsupervised release from the psychiatric institution in which he had been incarcerated for his earlier crimes.

An adopted child, Krueger lived in numerous foster homes as an infant, and showed signs of severe emotional trauma when he found a permanent foster home at the age of 3. Unable to adjust to social situations, he was bullied by his peers. He would often wander from his home by foot, bicycle or train to parts of Toronto, where he would molest dozens of children, and ultimately murder three. Found not guilty by reason of insanity for his crimes, he was sent to a psychiatric facility. Psychiatrists placed him in experimental treatment programs for psychopathy, but those treatments proved ineffective when he murdered a fellow psychiatric patient in 1991; after his death in 2010, he was described in the Toronto Star as "the serial killer they couldn't cure."

Early life

Peter Woodcock was born in Peterborough, Ontario to a 17-year-old factory worker, Waita Woodcock, who gave him up for adoption after breastfeeding him for a month. Adoption agency records report that the newborn, Peter, showed feeding problems and cried constantly. As an infant, he stayed in various foster homes, unable to bond with any of his foster parents. After his first birthday, he became terrified of anybody approaching him, and his speech was incoherent—described as strange whining animal noises. He was also physically abused by at least one of his early foster parents, with a 2-year-old Woodcock having to be given medical treatment for an injured neck after receiving a beating. He was placed into a stable home at the age of 3 with foster parents Frank and Susan Maynard, an upper-middle-class couple with another son. Susan Maynard, who was described as a "forceful woman with an exaggerated sense of propriety", became strongly attached to the maladjusted child who would still scream when someone approached him. By the age of 5, Woodcock remained socially maladjusted and became the target of neighbourhood bullies.

Worried about the child's fragile emotional state, Frank and Susan Maynard would regularly bring him to the Hospital for Sick Children, where Woodcock received extensive treatment. Woodcock was sent to a private school, but again failed to make friends or interact successfully with his peers and remained isolated. By the age of 11, he was described as an "angry little boy"; a Children's Aid Society report on him from that time read:

Signs of Woodcock's violent fantasies were present at this time also, seen when a social worker was walking with him at the Canadian National Exhibition and Woodcock muttered, "I wish a bomb would fall on the Exhibition and kill all the children". Woodcock was sent to a school for emotionally disturbed children in Kingston, Ontario, and began acting on his strong sexual urges with other children—with Woodcock stating that here he had consensual intercourse with a 12-year-old girl when he was 13. When he turned 15, he was discharged from this school and returned to live with his foster parents, but was soon re-enrolled at his original private school, where he again failed to connect with his peers. At the age of 16, he left the private school again and was sent to a public high school, where children from the neighborhood instantly recognized him and resumed the bullying; he transferred to a private high school six weeks later. While his peers again shunned him, his teachers there remembered him as a very bright student who excelled in science, history, and English, and who frequently scored 100 percent on his tests.

Early crimes

Peter Woodcock's prized possession was a red and white Schwinn bicycle on which he satisfied his continuing compulsion to wander. He rode the bike to the far reaches of the city—even during the deep, cold Toronto winters—and evolved a fantasy in which he led a gang of 500 invisible boys on bikes called the 'Winchester Heights Gang'. His foster parents were aware of this fantasy and his compulsion to wander, but they were unaware that he had begun travelling around Toronto on his bike and sexually assaulting children.
