Murder of Tammy Homolka

Tammy Lyn Homolka (January 1, 1975 – December 24, 1990) was a 15-year-old Canadian girl and the first murder victim of Paul Bernardo and her older sister, Karla Homolka, eight days before what would have been Tammy's 16th birthday. Her official cause of death was listed as choking to death on her own vomit and was initially ruled an accident.

After Karla revealed to her aunt and uncle that Bernardo was the Scarborough Rapist, as well as her involvement in the murders of Leslie Mahaffy and Kristen French, the Niagara Regional Police Service reopened its investigation into Tammy's death and the couple were subsequently arrested. Bernardo was convicted of two first-degree murders and two aggravated sexual assaults, and sentenced to life in prison without parole, while Karla was convicted of manslaughter and sentenced to 12 years imprisonment. The disappearances, arrests, and convictions were widely covered in the media, becoming one of the most notorious crimes in Canadian history.
