Forensics in Flames

Over the past 20 years, there’s been a revolution in the science of arson investigations. Many of the clues that had been used for decades to determine that a fire was not accidental, especially the analysis of burn patterns on walls and floors, have been proven to be false. Reporter Michael May looks closely at two deadly fires to explore the cutting edge of fire science. For more on this case, here’s Dave Mann of the Texas Observer on NPR’s All Things Considered last year: This episode was produced by Michael May in 2013 for PRX’s STEM Story Project. It was hosted for this episode of Transistor by Genevieve Sponsler and mixed for Transistor by Josh Swartz. Image from Shutterstock.
