When Milwaukee police stormed Jeffrey Dahmer's apartment in 1991, they saw this suspicious 57-gallon drum sitting in the corner of his bedroom — and noticed the overpowering odor emanating from it. 

When they looked inside, they found three dismembered human torsos dissolving in an acid solution. 

A more detailed search of the home revealed four severed heads in the kitchen, seven skulls in the bedroom and closet, and two human hearts in the fridge.
