The FBI is doing everything they can to track down Nancy Guthrie's kidnapper - and it sounds like they have a long list of possible persons of interest! According to Brian Entin via X (Twitter) on Monday, the authorities have been stopping into many Arizona gun stores to see if they saw anyone of interest. Surveillance footage outside of Nancy's home on the night she disappeared showed a masked man with a gun holstered oddly in front of his crotch, so it's understandable why they're asking around.
