#he has knowledge

Well you could bury it, dissolve it in acid, hide it in your refrigerator, throw it in the lake, throw it in a barrel of salt and into a pit, inside an empty apartment, bury it under a garden, maybe even bury a dead pet above the corpse to avoid suspicion. You could even cook it and eat it! Or cut it up and flush the pieces down the toilets of many different hotels... Maybe I'm getting a bit out of hand...

Well, in any case. Good luck with that corpse! Trust me, you'll never forget the smell.
