Tommaso Cioni Interviewed as Search for Missing Tucson Woman Nancy Guthrie Intensifies
The investigation into the disappearance of 84-year-old Nancy Guthrie has entered a critical stage as authorities continue working to reconstruct the events leading up to the Tucson woman’s unexplained disappearance. In a significant development, investigators confirmed that Tommaso Cioni, Guthrie’s son-in-law, voluntarily participated in an extended interview with law enforcement.
Online speculation quickly fueled rumors that Cioni had been arrested. However, the Pima County Sheriff’s Department clarified that he was not taken into custody and that no charges have been filed. Authorities described the interview as a routine investigative step often conducted in missing-person cases, particularly when detectives are exploring the possibility of foul play.
Investigators are focused on establishing a detailed timeline of Guthrie’s final known movements. According to authorities, she was last seen on the evening of January 31, 2026, after having dinner with her daughter, Annie Guthrie, and Cioni. Detectives say Cioni drove Guthrie home to her residence in Tucson’s Catalina Foothills and reported arriving at approximately 9:45 p.m. He told investigators that he remained in his vehicle until he saw her enter the home through the front door.
Concern grew the following morning when Guthrie failed to attend church and family members were unable to contact her. Relatives and deputies subsequently checked on her residence, where investigators say they encountered circumstances that immediately raised concerns about her well-being.
As the search continues, authorities are urging anyone with information about Guthrie’s whereabouts or activities on the night she disappeared to contact investigators. Officials have not identified any suspects and continue to pursue multiple leads as they work to determine what happened to the missing Tucson resident.
