David and Catherine Birnie went on a four-week crime spree in Australia in 1986. They abducted, raped, and murdered four women in their suburban home, and no one suspected them. The serial killer couple picked up their fifth victim, Kate Moir, November 9. On November 10, Kate showed up at the police department to report a story almost no one could believe.
