In 1990, Florida police were on a frantic search for a killer. Seven men were dead, their bodies scattered along state highways. Terrorized motorists heard of the bullet-ridden victims of the Interstate Killer - but the investigative trail was cold and there was no end in sight. The killer behind the spree was Aileen Wuornos—a complex, misunderstood misfit who hitchhiked near truck stops, selected her victims at random, and lured them to secluded locations. It took good old-fashioned police work, a little luck, and a lover's betrayal, to finally bring Wuornos' killing spree to an end. This episode features rare interviews with victims' family members, and Wuornos' best friend.
