Jeffrey Dahmer's Apartment
His wasn't a bunker, a hole or a compound. His was a one-bedroom in Milwaukee's Oxford Apartments. Serial killer and cannibal Jeffrey Dahmer occupied No. 213 at the time of his arrest in the summer of 1991. TIME noted that his neighbors had had clues that something was off: "A power saw buzzed at odd hours. The putrid odor of rotting meat flooded the corridors. Occasionally, a tenant would hear a cry or the thump of a falling object on the second floor." Dahmer, who confessed to murdering 17 boys and young men, surrounded himself with evidence of his gruesome crimes: not just pictures of mutilated human beings, but also skulls, severed heads and other body parts. The Oxford Apartments were later destroyed, as was Dahmer, who was killed by another inmate in 1994.
