What a dead pig can teach police about murder

If you're visiting Calgary this summer, don't be surprised if you see a dead pig floating in the Bow River. That's the message Calgary police are sharing with residents after launching a new project to understand what happens to human remains that end up in a river. Dr. Iain Phillips, biology professor at the University of Saskatchewan and the project’s lead researcher, joins us to explain the science behind the study and why this research matters to help bring answers to families and investigators.
