Some serial killers have taken on an almost mythical identity in the eyes of the public. Individuals such as Charles Manson, Ted Bundy and Jack the Ripper have come to be seen as real-life monsters, evil creatures who exist on the very edge of normal human society and prey on its weakest members - prostitutes, drug addicts, young women, children and the elderly. The majority of serial killers appear at first glance to be very ordinary individuals. John Wayne Gacy, Reg Christie and Ed Kemper all passed for upstanding members of their communities, that is until someone noticed a strange smell about the place, investigated a trap door, or casually opened the boot. SERIAL KILLERS examines the lives of men and women who kill for the thrill of it, and just can't stop. It looks at the fiendish crimes of people like Fritz Haarmann, who sold human meat from his kills on the streets of Hanover; Leopold and Loeb, who murdered 14-year-old Bobby Franks just for kicks and Albert DeSalvo, who confessed to being the notorious Boston Strangler.
