Karla Homolka and Paul Bernardo: The Ken and Barbie Killers

Karla Homolka attracted worldwide outrage in the early nineties. The Canadian Barbie-lookalike had, with her boyfriend Paul Bernardo, participated in the 1991 and 1992 rape and murder of two teenage girls, Leslie Mahaffy and Kristen French, and the rape and killing of her sister Tammy. Following a plea-bargain, she received a reduced sentence for manslaughter, even though videos showed her playing an active role in the pair's crimes.

The Murder Files is a series of individual titles, giving condensed accounts of some of the most appalling and notorious killers of all time.
