Paul Bernardo and Karla Homolka murdered three young girls together between December of 1990 and April 1992. One of the three victims was Karla’s 15 year old sister.
• Tammy Homolka - Bernardo had taken a liking to Karla’s younger sister, Tammy, from the beginning of his relationship with Karla. He quickly became obsessed with her, going as far as making Karla pretend to be her sister during sex and watching Tammy undress without her knowing. Paul continuously asked Karla if he could have sex with Tammy, who was a virgin. Karla eventually agreed and managed to obtain a bottle of Halothane from the veterinary clinic which she worked at and on 24 December, 1990 , it was used to sedate Tammy. Tammy was initially drugged with a mixture of Halcion and alcohol and then Halothane was used on a cloth to keep Tammy unconscious. Taking turns to hold the camera, Paul and Karla filmed the whole rape. Whilst still sedated, Tammy choked to death on her own vomit. The death was ruled as an accident, despite a large burn left on the face of Tammy Homolka from the Halothane.
• Leslie Mahaffy - On the day of her abduction (June 14, 1991) 14 year old Leslie Mahaffy attended the wake of a friend who had died in a car accident. After the wake, she had gone drinking in the woods with a large group of teenagers. Leslie was walked home by friends just before 2am, where she discovered the back door was locked. She told her friends to go home but, then discovered that the front door was also locked. Leslie walked to a pay phone alone to ask a friend if she could sleep over. Her friend said no and at 2:30am Leslie told the friend that she would go home and attempt to wake her mother up. Bernardo saw Leslie walking alone and offered her a cigarette, telling her it was inside his vehicle. Bernardo wrapped a sweatshirt around Leslie’s head and forced her into his car. Over the next 24 hours, Leslie was raped and tortured by both Paul and Karla. Again, they filmed themselves doing so. Bernardo killed Leslie on the Saturday night by strangling her with an electrical cord. Bernardo’s grandfather’s circular saw was used to dismember Leslie’s body, the pieces were then encased in concrete and thrown into Lake Gibson. Her body was found on June 29, 1991.
• Kristen French - 16 year old Kristen French was walking home from school on April 16, 1992, when she was asked by Paul and Karla for directions. While Kristen helped Karla with directions, Paul attacked Kristen from behind and forced her into the car by knife point. This abduction was seen by several eye witnesses. Kristen was held for three days, Paul and Karla, once again, filmed themselves degrading, torturing and sexually humiliating her. She was also forced to drink a large amount of alcohol. She was murdered on April 19, 1992. Kristen’s body was found naked in a ditch the next day.
