Pima County Sheriff Chris Nanos Faces Renewed Scrutiny Amid Nancy Guthrie Investigation

14 February 2026 U.S. News

TUCSON, Ariz. — As the investigation into the disappearance of Nancy Guthrie approaches its two-week mark, Pima County Sheriff Chris Nanos finds himself under intense public and media scrutiny. The high-profile case has reignited criticism of Nanos, whose tenure has been marked by a series of controversies, including FBI investigations and legal disputes with deputies and political rivals.

Since the onset of the Guthrie case, the Pima County Sheriff’s Department has coordinated closely with the FBI, with Sheriff Nanos publicly defending the department’s ongoing efforts. In a recent interview, Nanos addressed questions about the investigation, notably denying reports that a glove was found at Guthrie’s home, and emphasizing the department’s commitment to working alongside federal agents. The FBI’s involvement underscores the complexity and sensitivity of the case, which has drawn national attention.

However, Nanos’s leadership has been questioned before. Court records and news reports reveal that in the lead-up to his 2024 re-election, which he narrowly won by 481 votes, Nanos placed Heather Lappin, a lieutenant at the Pima County Jail and his political opponent, on administrative leave. He also took similar action against Sgt. Aaron Cross, head of the Pima County Deputies Organization and a vocal critic. These moves have been viewed by some as politically motivated and have contributed to a fraught atmosphere within the department.

Further complicating the investigation are reports that Walmart sales records have become critical evidence, as federal agents sift through data to piece together Guthrie’s last known movements. The use of technology and data analysis in the investigation reflects broader trends in law enforcement’s adoption of advanced tools to solve complex cases. Experts have noted the importance of rapid DNA testing and forensic analysis in such investigations, as highlighted by retired FBI agents advocating for expedited procedures.

The controversy surrounding Sheriff Nanos is not limited to personnel disputes. The department itself has been the subject of an FBI investigation in recent years, raising questions about internal practices and oversight. Despite these challenges, Nanos has maintained his position and continues to lead the department through this high-stakes inquiry.

The public’s demand for transparency and accountability has grown louder as the search for Nancy Guthrie continues. Legal experts and community leaders have called for clear communication from law enforcement agencies, while emphasizing the need for thorough and unbiased investigation.

As the investigation unfolds, the community and the nation watch closely, hoping for answers in the case of Nancy Guthrie and clarity regarding the leadership of Sheriff Nanos amid ongoing controversy.
