The disappearance of Nancy Guthrie, an 84-year-old woman from Tucson, has become a deeply puzzling case that continues to raise questions across the country. On the evening of January 31, 2026, Nancy was last seen when the garage door at her home closed at approximately 9:50 p.m. By 2:28 a.m. the next morning, she had vanished without a trace.

Earlier that evening, Nancy had attended a family dinner at her daughter Annie’s home. Annie’s husband, Tomaso Chioni, later drove her back home and reportedly watched as she safely entered the house before leaving. This moment is considered the final confirmed sighting of Nancy.

Investigators later discovered that several security cameras around the property had been deliberately disabled by a masked individual. The actions suggested the person had prior knowledge of the home’s security system and layout. Because of the suspicious circumstances, the case quickly escalated into a major investigation involving both the Pima County Sheriff’s Department and the Federal Bureau of Investigation.

Authorities launched extensive searches in the surrounding desert areas using helicopters, drones, and search dogs. Thousands of tips poured in from the public, but the investigation produced few clear answers.

Although Tomaso Chioni was initially considered a person of interest and his vehicle was held for forensic testing, law enforcement later announced that he had been cleared. However, some aspects of the case—including mixed DNA evidence found in the home and the unexplained disabling of cameras—continue to raise unanswered questions.

Nancy’s daughter, Savannah Guthrie, a well-known television journalist, has publicly appealed for help in finding her mother. The family has also offered a $1 million reward for information leading to Nancy’s safe return.

Despite months of investigation, the case remains unsolved. Authorities say the search continues as they analyze forensic evidence and pursue new leads in hopes of discovering what truly happened that night.
