On December 23, 1990, at a Christmas party at the Homolka family home, Bernardo and Homolka served Homolka's 15-year-old sister Tammy alcoholic drinks spiked with Halcyon. After family members retired, the two took Tammy to the basement and Homolka held a cloth soaked in Halothane to Tammy's mouth. Once Tammy was unconscious the couple raped her. During the rape Tammy began choking on her own vomit and ultimately died. The drugs in Tammy's system went undetected and her death was officially ruled an accident.
Karla eventually confessed her involvement in her sister's death in a letter she wrote to her parents. For Tammy's death, Homolka received and additional two year prison sentence on top of the 10-year-sentence she received in exchange for her complete disclosure of the couple's crimes.
Tammy Homolka is buried at the Victoria Lawn Cemetery in St. Catharines, not far from her parent's home.
