A Deadly Duet: The 10 Scariest Serial Killer Couples

They met in 1987 in Toronto, married in 1991. Six months before the wedding, Karla wanted to give her future husband a special gift - the virginity of her 15-year-old sister Tammy. Bernardo knew that Karla was not a virgin when they got together, which did not give him peace. Therefore, on the eve of Christmas 1990, Karla mixed alcohol and halothane to put her younger sister to sleep. After that, she and her fiancé filmed, as the poor girl was raped.

In the middle of the night, Karla's sister choked on her vomit and died. The serial killer couple then assumed death as an accident, so Bernardo and Karla continued to live their fantasies, raping and killing young girls.
