Killer's Vault Eric Roberts and Elisabeth Rohm

How did Killer Clown John Wayne Gacy develop into the sexual sadist and serial killer responsible for murdering at least 33 young men and boys? His letters and recorded phone calls reveal all.

Convicted of only two murders, former police officer Gerard Schaefer is believed to have committed 80 to 140 of the most barbaric rapes and murders the FBI has ever seen. In Part 1, hear in Schaefer's own words how he trained on young female corpses dug from their fresh graves in his quest to become, in his mind, the best serial killer of all time.

In Part 2, Gerard Schaefer's letters reveal, in horrific detail, how he stalks, captures, tortures, rapes and disembowels his prey and the pure joy that comes with it.

David Alan Gore was convicted of raping, murdering and dismembered six women, but his letters reveal at least thirty in graphic detail, crimes committed with his cousin, Fred Waterfield. He takes most pride in the mother/daughter slaughters and his first rape victim, Waterfield's little sister.

Roy Norris and Lawrence Bittaker were dubbed the “Toolbox Killers” by the media because of their predilection for torturing their teenage female victims using a pair of pliers. FBI profilers consider them among the most savage and cruel in American history and their remorseless letters prove why.

Dubbed “The Night Stalker,” Richard Ramirez reveals himself as a sadistic sexual and murderous deviant. He writes about his unquenchable passion for dominating women through bondage and torture, his lust for women's feet (on living and dead bodies) and his need to be seen as a superstar in pop-culture.
