Pima County Sheriff Chris Nanos has headed the investigation into Nancy Guthrie's disappearance from her Arizona home since day one

Backlash has been steadily building against the lead investigator in the case of Nancy Guthrie's disappearance on February 1, with Pima County Sheriff Chris Nanos coming under fire for past disciplinary issues as the investigation approaches its 12th week. 

The sheriff's history at the El Paso Police Department in Texas has drawn criticism as he resigned from his position in 1982 in order to avoid disciplinary action. He addressed the allegations that he misrepresented himself when applying for a job at the Pima County Police Department in the '80s, after leaving his job in Texas.

Chris' lawyer responded to the probe into his past with a 22-page document that explained his conduct. "Sheriff Nanos resigned from the El Paso Police Department in 1982. At the time of his resignation, he held the rank of corporal," the document read.

Sheriff Chris Nanos has come under fire in recent weeks

"His resignation came in the wake of a dispute with a supervisor over the towing of vehicles. The supervisor wanted to impose a three-day suspension for insubordination. Sheriff Nanos appealed that recommended discipline to the Chief, who found in favor of the supervisor."

"Rather than accept a three-day suspension, Sheriff Nanos offered to resign in lieu of discipline. The Chief accepted his offer, and Sheriff Nanos resigned," he continued. The document added that he had not lied about his employment history, and wrote on his resume that he left the job in 1982, despite the Pima County Sheriff's Department website stating that he left in 1984. 

Chris' lawyer also acknowledged the disciplinary actions he was subject to at El Paso, including "counselling, reprimands and suspensions". The letter then spoke on the sheriff's previous statement under oath that he had never been suspended as a result of disciplinary action.

"It is 100% correct that Sheriff Nanos was never suspended during his four decades of decorated and faithful service with the Pima County Sheriff's Department," his lawyer wrote to the Pima County Board of Supervisors. 

"However, Sheriff Nanos was suspended more than forty years ago while employed by [the] El Paso Police Department. In the context of his live deposition, Sheriff Nanos did not understand the question related to discipline with a different agency not governed by the Arizona Peace Officers' Bill of Rights."

Social media users quickly shared their distaste for the sheriff after his past in El Paso came to light. "Everyone wants him gone," wrote one X user, while another added that "people are angry". A third chimed in that Chris had "botched this [case] from the start," while a fourth added: "My gut is telling me it was totally mishandled."

Chris faced backlash from social media users

Chris did garner support from some social media users, with one writing: "Wasn't this decades ago? [In my opinion] he is working hard to find Nancy Guthrie," while another added that the focus on his past was "fueling a dishonest narrative" about Chris' competency.

Nancy went missing from her Arizona home in February

The Pima County Sheriff's Department has worked closely with the FBI since Nancy went missing in February. While several suspects have been questioned regarding her disappearance, no arrests have been made, and DNA evidence is still being examined by the authorities. 

Nancy, the 84-year-old mother of Today show star Savannah Guthrie, was believed to have been taken by force from her home in Tucson, Arizona, after blood was found on the doorstep, and her personal effects were found inside the house.
