wrapped his sweatshirt quickly around her head, forced her into the vehicle, and took her to the home he shared with Homolka. Homolka's version of the story is similar, but she claims that once he got Mahaffy to the car to fetch the cigarette, he pulled a knife on the girl to get her compliance. Both agree that Homolka was not present during the kidnapping. Murder After 24 hours of rape and abuse by both of the killers, Mahaffy was murdered sometime on June 15, 1991. According to Homolka, Bernardo strangled Mahaffy with an electrical cord a second time when the first attempt left her unconscious for a few minutes. Homolka, a veterinary technician, had access to sedative drugs which were used to subdue Mahaffy, the same technique the pair used in the rape and inadvertent murder of Homolka's sister six months before. Bernardo stated that he was out of the room, preparing the car to transport Mahaffy to a location where she would be released, when the heavily-drugged Mahaffy died. He has claimed he did not even know she was dead until, after putting gas in the car and taking a shower, he tried to pick her up to carry her away. He said he and Homolka panicked, and that he tried to give Mahaffy artificial respiration. Both killers agree that they gave her a teddy bear to hold during breaks between assaults. On June 16, 1991, Bernardo and Homolka moved Mahaffy's body from an upstairs bedroom to the basement. During this time, Bernardo and Homolka hosted Homolka's family for a Father's Day dinner on the main floor of the house, with Homolka making a special effort to keep her mother from going downstairs. When the family left, Bernardo and Homolka used his grandfather's circular saw to dismember Mahaffy's body into pieces small enough to lift when covered with concrete. Later, in a confession to her aunt before revealing details to the police, Homolka claimed that Bernardo did this while she was at work on Monday. Bernardo's version asserts that she did not help him rinse and bag the body parts. Mahaffy's body was found dismembered and encased in concrete on June 29, 1991 in Lake Gibson near St. Catharines, Ontario. The concrete block containing the torso weighed over 200 pounds. Her braces and dental records confirmed her identity. Investigators immediately believed she had been raped and tortured. This
