Pima County Sheriff Chris Nanos is facing mounting pressure from local officials calling for his removal as he continues to lead the investigation into the disappearance of Nancy Guthrie, the mother of "Today" show co-host Savannah Guthrie.

Guthrie has been missing since February 1, when she was reportedly abducted. The case has stretched on for more than three months without resolution, creating tensions between investigating agencies.

Local leaders in Arizona are pushing to remove Sheriff Nanos from his position, accusing him of lying about his past record. The specific details of these allegations have not been fully disclosed, but they have added controversy to an already high-profile missing person case.

According to Fox News reporting, tensions have emerged between the FBI and the Pima County sheriff's office during the investigation. A retired lieutenant has suggested that potential connections to Mexico may have been downplayed early in the case to prevent federal involvement.

The investigation remains active as authorities continue searching for Guthrie. The case has drawn significant attention due to her connection to the prominent television journalist, though investigators have not provided recent updates on potential leads or developments in the search.
