Karla Leanne Homolka, also known as Karla Leanne Teale, Leanne Teale and Leanne Bordelais, is a Canadian serial killer who acted as an accomplice to her husband, Paul Bernardo, taking active part in the sexual abuses and murders of at least three minors in Ontario – including her own sister, Tammy Homolka – between 1990 and 1992. Often deemed as "the queen of manipulation", Karla was able to "blend in" normal society after her prison release and convinced the press, her lawyers, etc, that she was remorseful of her acts; to which she wasn't when in 2025 she joined the international, all-powerful ISG supergroups and gave bred to new crime sprees along with Bernardo again and other renowned killers in the group.
