Over a five-week period in 1986, four young women went missing from around Perth in Western Australia. 22-year-old Mary Neilson, 15-year-old Susannah Candy, 31-year-old Noelene Patterson and 21-year-old Denise Brown all disappeared without a trace, but police were sceptical that some were runaways and no links were drawn between the missing women. That was until November 10 1986, when a man standing outside a vacuum cleaner store was suddenly approached by a hysterical, barefoot young woman.
