#32- The British Jeffrey Dahmer - He Keeps Corpses As Roommates (Serial Killer Dennis Nilsen)

Police are called out about clogged drains underneath a house in London... doesn't really sound like detective work. BUT it soon becomes apparent that the drains have been clogged with human remains. Someone inside the house has been flushing human remains down the toilet. (Remember Jeffrey Dahmer?) The police think they're about to arrest a murderer but little do they know they've got a serial killer on their hands.
