They say pigs will eat anything. But can they diminish a whole human body? Surprisingly, science didn't have an answer to this question until recently. Forensic anthropologist, Dr Penny McCardle, has helped police investigate some of the most high-profile crimes in recent history, including the disappearance of William Tyrell and the 1986 murder of Roxlyn Bowie.  In this discussion with Kathryn Fox, hear about the investigation into the murder of Roxlyn, which included the biggest excavation in NSW Police history, and what would become the world's first study into what happens if a human body is fed to pigs.
