The cops found a trove of necrophelia and death:

Skulls stripped of hair and skin, stashed on the cannibal's shelves and in the fridge.

A pail that was full of hacked off hands.

A torso in the kitchen sink ripped open from the neck to groin.

A jar containing a pickled penis, a severed penis lying on the sink, and Another Severed Penis in the refrigerator as well as two human skulls!

A 15 gallon garbage can filled with rotting torsos. He soaked the large parts in acid untill they got "slushy", and would flush them down the john.

He had a sketch of a shrine to himself he was planning to build in his room. It was to have bones, skeletons, and by all accounts would have been a pretty creepy place. Presumably there would be only one worshiper at this altar!
