S1E7 Toxic Relationship: The Murder of Mary Yoder (Part 2)

Part two of our two-part episode, the murder of Mary Yoder. Yoder was a chiropractor in Buffalo N.Y. who was poisoned by Colchicine, and our guest -- Tony Martino -- was the digital forensic investigator who worked through the case.

As a 20-year veteran of the Utica, N.Y., Police Department, Tony Martino is an expert in cybersecurity, computer crime investigation and digital forensics. He's a recipient of the Wallie Howard Jr. Award for Excellence in Law Enforcement from the U.S. Attorney’s Office. In this episode, we pick up where Part One left off: the first prosecution of the case ended in a hung jury, and the second trial was about to begin. But between cases Tony and his team found crucial digital evidence: a backup of the prime suspect's phone made before she had wiped key evidence from the device.
