No institutional female bias tho
Karla Homolka was tried on June 28, 1993, though the publication ban the court had imposed limited the details released to the public, who were barred from the proceedings. She was sentenced to
12 years imprisonment on July 6, 1993.
According to Bernardo's testimony at his trial, on July 24, 1990, Karla Homolka laced spaghetti sauce with crushed Valium she had stolen from her employer, Martindale Animal Clinic. She served dinner to her sister, who soon lost consciousness. Bernardo began to rape Tammy while Karla watched.
Over the summer, he supplied Tammy and her friends with gifts, food, and sodas that had "a film and a few white flecks on the top."
Six months before their 1991 wedding, Karla Homolka stole the anaesthetic agent Halothane from the clinic. On December 23, 1990, Homolka and Bernardo administered sleeping pills to the 15-year-old in a rum-and-eggnog cocktail. After Tammy was unconscious, Homolka and Bernardo undressed her and Karla applied a Halothane soaked cloth to her sister's nose and mouth.
Karla Homolka wanted to "give Tammy's virginity to Bernardo for Christmas" as, according to Homolka, Bernardo was disappointed by not having been Karla's first sex partner. With Tammy's parents sleeping upstairs, the pair videotaped themselves as they raped her in the basement. Tammy began to vomit. The pair tried to revive her, then called 911, but not before they hid evidence, dressed Tammy, and moved her into her basement bedroom. A few hours later Tammy Homolka was pronounced dead at St. Catharines General Hospital without having regained consciousness.
Despite the pair's behaviour – vacuuming and washing laundry in the middle of the night, and despite the presence of a chemical burn on Tammy's face, Niagara Regional Coroner and the Homolka family accepted the pair's version of events. The official cause of Tammy Homolka's death was accidental – choking on her vomit after consumption of alcohol. The pair subsequently videotaped themselves with Karla wearing Tammy's clothing and pretending to be her. They also moved out of the Homolka house to a rented Port Dalhousie bungalow, to let her parents cope with their grief.
