The sheriff leading the investigation in the Nancy Guthrie case is facing bipartisan calls for removal from the county board of supervisors. A Democrat and a Republican plan to move to vacate Pima County Sheriff Chris Nanos’ office next week over allegations he lied about a history of suspensions and other disciplinary actions he received in the 1970s and 1980s as a member of the El Paso Police Department. “This is accountability for a guy who has evaded accountability for decades and is himself a public safety threat,” said Dr. Matt Heinz, a member of the Pima County Board of Supervisors.
