Authorities confirmed that Tommaso Cioni voluntarily participated in extended questioning regarding the disappearance of 84-year-old Nancy Guthrie. Despite early reports suggesting an arrest, no charges have been filed, and Cioni is not considered a suspect. Officials emphasized that interviewing individuals with recent contact is standard investigative procedure and does not imply guilt.
Nancy Guthrie was last seen on the evening of January 31, 2026, after dinner with her daughter Annie and Cioni in Tucson, Arizona. Cioni drove her home and left after she entered. The next day, Nancy was reported missing. Investigators found signs of possible forced entry, small amounts of her blood on the porch, and a disruption in her pacemaker signal, prompting authorities to treat the case as a potential abduction.
Separately, a California man was arrested for sending fraudulent ransom messages unrelated to the disappearance. The FBI has joined the investigation and offered a $50,000 reward for credible information. Search efforts include ground teams, drones, K-9 units, and forensic analysis.
Sheriff Chris Nanos and officials continue to review surveillance footage, electronic data, and public tips, emphasizing that no suspect has been named and voluntary interviews are part of normal investigative practice. Nancy’s family has urged the public to provide verified information and avoid speculation.
The investigation remains active, and authorities encourage anyone with relevant information to contact law enforcement directly.
