You want truly sick murders? Look no further than Richard Trenton Chase, the Vampire of Sacramento. This is a guy who thought his blood was poisoning him, and to cure it, drank the blood of every living thing he could get his hands on. You can't go wrong with a guy who ate a baby's brains to keep his body from decaying.
