Jennifer Coffindaffer joins Hidden Killers Live to assess the physical evidence in the Nancy Guthrie case — and separate what's real from what's noise. The glove found two miles from the house has dominated headlines, but its DNA doesn't match anything at the property and hit nothing in CODIS. Coffindaffer tackles the question no one else is asking: should this glove even be treated as evidence in this case?

Inside the home, the DNA picture is a mess — a mixture of multiple contributors that investigators are still trying to separate. Coffindaffer explains what that process actually involves, what determines success or failure, and whether the sample is usable for the genetic genealogy approach investigators are now pursuing.

The lab fight gets a direct assessment: Nanos sent evidence to a private Florida lab while the FBI wanted it at Quantico. Coffindaffer evaluates both arguments and addresses whether evidence may have already been degraded. The conversation also covers Google's admission that additional Nest footage likely cannot be recovered, the ongoing pacemaker search, and why 50,000 tips haven't produced a suspect.
