Vanished Without a Trace: The Mystery Deepening Around Nancy Guthrie

Surveillance released by authorities shows a masked person with a firearm on her doorstep around the time she went missing. It’s unclear who this person is.

The FBI and Pima County Sheriff’s Office are leading the investigation, have executed search warrants in the area, seized vehicles, and collected DNA and glove evidence. So far, no arrests or named suspects have been made.

The FBI has received tens of thousands of tips and raised the reward for information to $100,000.
