After serial killer John Wayne Gacy kidnapped his victims he would go on to torture them for hours. Unlike many other serial killers that are driven by lust, Gacy was not known to rape his murder victims. Instead, Gacy would force them to perform oral sex. The only time he was known to penetrate his victims was when he would use foreign objects. However, Gacy was known to have raped many of the victims he allowed to survive. After he was arrested Gacy claimed that he developed a rope technique in which he would strangle his victims for hours before they died. Many experts claimed that Gacy was just as sexually violent as Ted Bundy, however many people did not know this because articles which reported the case from the 1970s did not state what Gacy would do to his victims and how they were murdered.
