The search for 84-year-old Nancy Guthrie has entered a critical phase as authorities continue piecing together the timeline surrounding her disappearance from her Tucson home. Investigators confirmed that her son-in-law, Tommaso Cioni, voluntarily participated in a lengthy interview with law enforcement. Officials emphasized that he has not been arrested and is not facing charges, describing the conversation as part of routine efforts to clarify events from the evening of January 31, 2026.
According to authorities, Nancy was last seen after sharing dinner with her daughter, Annie Guthrie, and Cioni. Reports indicate that Cioni drove her home around 9:45 p.m. and observed her entering the residence. Concern arose the following morning when Nancy did not attend church and failed to respond to phone calls. When deputies arrived at the property, they discovered signs suggesting a possible disturbance near the front entrance.
Investigators later confirmed that a disconnected security camera and traces of blood found on the porch belonged to Nancy. These findings shifted the investigation toward a suspected abduction. Additional digital evidence heightened urgency, as officials noted an interruption in signals from her pacemaker shortly after 2:00 a.m. on February 1. The Federal Bureau of Investigation has joined local authorities to assist with forensic analysis and search coordination. Law enforcement reiterated that interviewing relatives is a standard investigative procedure and should not be interpreted as an indication of wrongdoing.
The case has also been complicated by fraudulent ransom communications, leading to the arrest of an unrelated individual accused of attempting to exploit the situation. Search operations now include K-9 units, drones, and aerial scans across the Catalina Foothills area. The FBI has announced a $50,000 reward for credible information that could advance the case. Authorities continue urging members of the public to come forward with any relevant details as the investigation remains active and ongoing.
