James Foley, known as The Water Street Butcher (named for the location where his first three victims were found), was a cop. He would “arrest” prostitutes, then torture, murder, sodomize and mutilate their corpses. All of his victims had been cut from mouth to ear, were missing sections of skin, and were left naked and mutilated in or near the Hudson River in upstate NY. Apparently, Foley shot videos of everything he did, from stalking to disposing of bodies. These tapes have become known as The Poughkeepsie Tapes, after the town they were found in, Poughkeepsie, NY. These tapes are considered by many to be the most horrifically graphic collection of videos ever assembled. Kill count: 12+ (source)
