Regarded as Australia’s first true serial killer, William MacDonald murdered five men in gruesome crimes that included postmortem mutilation. Apart from his first victim, who MacDonald killed in a flat in Brisbane, MacDonald’s murders took place in Sydney in the early '60s. He lured his victims to dark spots in public places then stabbed them multiple times before cutting off their genitals. At the time of his death in jail in 2015, at the age of 90, MacDonald was the longest-serving prisoner in custody.
