5: The Butcher of Wollongong (Mark Valera) | Australia

As police walked through the diabolical crime scene at Albion Park, Australia, they found David O’Hearn's body. A pentagram, an inverted cross and the word ‘SATAN’ were smeared onto the walls in the victim’s own blood. This murder was to become one of the most heinous killings ever committed in Australia.
