Two 18-year-old girls disappeared on the Flinders Highway in 1972. One was found murdered, the other has never been found.
In this first episode of our special series for Outback Murder Highway, Tim & Xanthe are joined by investigative journalist Amelia Oberhardt to dissect the unsolved case of Anita Cunningham and Robin Hoinville-Bartram. Could police have missed crucial evidence all those years ago that could prove  they were victims of one of Australia's most notorious serial killers?
