Paul Bernardo & Karla Homolka
The case known as the “Ken and Barbie Killers”
Paul Bernardo and Karla Homolka abducted, sexually assaulted, and killed teenagers Leslie Mahaffy and Kristen French in Ontario. Homolka also helped drug her younger sister Tammy, who died after being assaulted. Bernardo was convicted of murder; Homolka received a twelve-year manslaughter sentence under a plea agreement that became controversial when videotapes revealed her involvement.

The case involves real people, including Leslie Mahaffy, Kristen French and Tammy Homolka. Their lives should not be reduced to the nickname attached to the offenders.
Begin with a clearly identified source. The Department of Justice Canada’s analysis of resolution agreements discusses the legal context of the Homolka agreement and Bernardo’s 1995 convictions. It is a government research publication, not the underlying judgment.
Books provide narrative and interpretation. The publisher pages for Invisible Darkness and Lethal Marriage establish their authors and subjects; they are not independent verification of every statement in those books. Read different accounts critically.
Documentaries also make editorial choices. A dramatized movie goes further, potentially condensing events and inventing dialogue. Neither should silently stand in for a primary source.
This case guide is a starting collection. We link to sources, identify the type of material, and leave space for further reporting, podcasts and lawfully shareable court documents.
