FORENSICS: Solving crime with dirt

Heard of a smoking gun? What about a smoking shovel?  Tracking down killers has never been part of the traditional job profile for people who study soils, but when the bodies of two women believed to be murdered could not be located, police gave pedologist, Professor Rob Fitzpatrick a call. In this episode with Kathryn Fox, Rob reveals how soil has been the key to cracking complex criminal investigations, from unsolved homicides to illegal dinosaur nest smuggling and counter-terrorism operations.  This episode contains descriptions of violence against women and children, for support, dial 1800 RESPECT on 1800 737 732. See omnystudio.com/listener for privacy information.
