Pima County Sheriff Chris Nanos is facing multiple allegations that have drawn public attention during his department's investigation into Nancy Guthrie's disappearance.

Nanos is accused of perjury related to statements about his early career history. The specific details of these allegations and when they were made have not been disclosed by authorities.

Separately, the sheriff allegedly brought a loaded firearm through a Transportation Security Administration checkpoint at an airport. A Tucson resident has claimed that Nanos avoided consequences that a regular citizen would typically face in such circumstances.

The timing of these allegations coincides with ongoing scrutiny of the sheriff's department as it investigates the disappearance of Nancy Guthrie. The connection, if any, between the various allegations and the missing person case has not been established.

Neither Sheriff Nanos nor his department has publicly responded to the allegations. The TSA has not confirmed details about any airport security incident involving the sheriff.
