FORENSICS: Erotic asphyxiation & murder | Sam Spencer

Behind every DNA sample is a person with a story. But when does DNA evidence reveal the truth? And when does it mislead? And in places like Tennessee, where the stakes are life or death, how much should we trust the science presented in court? Sam Spencer is a forensic biologist who has worked on over 1400 cases and provided expert testimony across the US. In this episode hosted by Kathryn Fox, hear the chilling reason why Sam chose this career path, what it's like working for the prosecution versus the defense, and unravel a case far more complex than it appears on the surface.See omnystudio.com/listener for privacy information.
