'DEREK PERCY - Australian Psycho is the story of Australia’s ultimate ‘cold case’ police investigation. In 1969, Derek Ernest Percy was captured after the abduction and murder of a 12-year-old school girl near a lonely beach on Melbourne’s Mornington Peninsula. Found not guilty of murder on the grounds of insanity, Percy was detained at the ‘governor’s pleasure’ and was Victoria’s longest serving prisoner deemed too dangerous to be released.'
