Episode Details

The physical evidence in the Nancy Guthrie disappearance has not produced a suspect, a match, or a confirmed connection to whoever took the eighty-four-year-old from her Tucson home nineteen days ago. Retired FBI Special Agent Jennifer Coffindaffer joins True Crime Today to assess what investigators are actually working with.

The DNA inside Nancy's home is a mixture — multiple people in a house with regular visitors. Still being separated. The glove found two miles away missed in CODIS and doesn't match property samples. Genetic genealogy is the next move, but it needs a clean profile that may not exist yet. Coffindaffer breaks down each forensic avenue: what's viable, what's compromised, and what investigators should stop spending time on.

The lab controversy gets examined — why evidence went to a Florida facility instead of the FBI's Quantico lab, what Othram's public criticism means, and whether the DNA samples have been degraded by the testing process. Coffindaffer also addresses the pacemaker helicopter search, the loss of potential Nest footage, and the 50,000 tips that haven't cracked the case open.
