On a freezing night in January, 1977, Chilton picked up a young woman who was hitchhiking in Winnipeg.
After holding her in his car for several hours, he stopped and asked her to kiss him. When she instead hopped out to flee, Chilton tried to run her down. He then got out of his car, forced her to the ground and raped her. He stripped her and choked her into unconsciousness and left her in an isolated, icy field.
"As a result of your actions, the victim suffered severe frostbite, required skin grafts and spent three months in the hospital recuperating," the National Parole Board said of Chilton when he was denied parole in 2006.
He was released from Saskatchewan Penitentiary on mandatory supervision in 1987 after serving nine years of his 14-year sentence for that crime and moved to Kitchener where he befriended a divorced mother of two.
Shortly af ter Chilton moved in with the woman, he raped her 15-year-old daughter in the basement of their townhouse while her family slept upstairs.
He admitted in a Kitchener court in 1990 that he attacked Heather Corey while she was doing laundry.
He stripped her and raped her on a basement couch and then smothered her to death.
Chilton poured gasoline over her body and set it ablaze.
When the smoke alarm sounded, he woke her mother and her younger brother and called 911 to report the fire. An autopsy, however, showed Heather died before the fire.
