Part one of a two-part episode, with a case that involved so many truckloads of evidence we couldn’t pack it all into one podcast. It involved two trials, three main suspects, and hours of forensic analysis by our guest and his team.

This case is about the murder of Mary Yoder, a chiropractor in Buffalo N.Y. who was poisoned by Colchicine, a deadly substance that has agricultural and medical uses. Our guest today is Tony Martino, the forensic investigator who worked through the case.

As a 20-year veteran of the Utica, N.Y., Police Department, Anthony Martino is an expert in cybersecurity, computer crime investigation and digital forensics. A nine-year member of the United States Secret Service electronic crime task force, and co- founder of the Central New York Internet Crimes Against Children Task Force, Martino received the Wallie Howard Jr. Award for Excellence in Law Enforcement from the U.S. Attorney’s Office.
