Admissible: Shreds of Evidence

Admissible: Shreds of Evidence

13 wrongful convictions all tied to one forensic analyst. The analyst – Mary Jane Burton – was hailed as a hero for saving the DNA evidence that led to the exonerations. But when reporter Tessa Kramer starts investigating, she meets a former lab trainee with a very different – and much darker – story to tell. Over the course of 12 episodes, Kramer unravels this mystery, searching for proof of explosive allegations against Burton and a possible cover-up at one of the nation’s leading crime labs. An original podcast from VPM and Story Mechanics, future seasons of Admissible will investigate the role of evidence in our legal system.
