FORENSICS: How to tell a fire was deliberately lit

In the 1990s, a deliberately fire in Sydney left 8 people dead. But how was it lit? How can forensics tell, and what information do they need to build a case for conviction?  Professor Peter Ellis is a veteran of forensics in Australia and has worked across a number of high profile criminal investigations. As well, he's worked overseas, in mass grave sites in Kosovo and mass disasters like the 2004 Boxing Day Tsunami.  In this episode of Crime Insiders: Forensics, understand Peter's career, and the toll this type of work takes as Kathryn Fox takes us through his career and his incredible work. See omnystudio.com/listener for privacy information.
