The Chicago Rippers
Holmes designed a "murder castle" that was a three-story hotel-like structure that included soundproof sleeping chambers with peepholes, asbestos-padded walls, gas pipes, sliding walls, and vents that Holmes controlled from his bedroom. The building had secret passages, hallways that went in circles, false floors, rooms with torture equipment, and a specially equipped operating room. There were also greased chutes that emptied into a cellar, where he had placed a very large furnace.
Finally caught after killing a man in Philadelphia, he was convicted of murder and on May 7, 1896, taken to the hangman's noose. He now stands as one of the most fiendish killers in American history.
Just over three decades later, in December 1979, police in the Chicago suburb of Des Plaines followed a man they believed had abducted a missing boy and quickly learned that prominent businessman John Wayne Gacy had secrets to hide: while he performed as a clown for children in the hospital and threw block parties for neighbors, he also lured young men to his home to strangle, rape, and kill them. He buried twenty-eight in his crawl space, explaining the terrible odor to neighbors as "septic fumes," and then tossed five more victims into the Des Plaines River. The case riveted America as sets of remains were removed from his home, one by one. The final official tally of Gacy's victims was 33. He was convicted of first-degree murder and received the death penalty, although there were times when he tried to blame some of the men who had worked for him. One of those men was Robin Gecht.
