Bob Berdella wasn't caught, until a victim who had endured several days of fisting, felching, testicular electric torture and drano injections escaped wearing nothing but a dog collar with blood dripping from his violated anus.
Ran a shop in the Midtown ghetto of Kansas City, Missouri. The shop - Bob's Bizarre Bazaar - was where he displayed the skulls of his victims and other trophies.
Disposed of his victims in trash bags and/or fed them to his dumbass friends.
Somehow managed to be appointed as a substance abuse counselor by the Jackson County Municipal Court
