A quiet Saturday night in Tucson, Arizona, turned alarming when 84-year-old Nancy Guthrie went missing. On Sunday morning, February 1, 2026, a family member called 911 after they could not reach her. Authorities quickly realized the situation was more serious than a routine welfare check, prompting an immediate response.

Nancy had been dropped off at her home between 9:30 and 9:45 p.m. on Saturday after dinner. Her daughter Annie, the last person to see her, reported no unusual behavior or warning signs. Sheriff Chris Nanos noted, “There were no red flags,” underscoring how ordinary the evening had seemed.

Troubling gaps soon emerged in the timeline. The family did not notice Nancy’s absence until around 11 a.m. the next day, after her church contacted them. Police were notified shortly afterward, leaving a critical overnight window investigators now consider central to understanding what happened.

By Sunday afternoon, homicide detectives were dispatched, an unusual move in a missing-person case. Officers observed circumstances inside Nancy’s home that prompted immediate allocation of extensive resources. Authorities emphasized her health, noting she is independent, mentally sharp, and not prone to wandering.

Evidence indicated Nancy did not leave voluntarily. Sheriff Nanos confirmed the scene was treated as a crime rather than a simple search. Investigators reviewed surveillance footage, recovered her cellphone, and asked neighbors to check cameras, focusing on evidence, witness interviews, and tips rather than search-and-rescue efforts.

For the Guthrie family, the uncertainty has been agonizing. Nancy, mother of Savannah, Annie, and Camron, is deeply missed. Savannah urged the public to remain vigilant and report any information. What began as a normal evening has become a haunting mystery, illustrating that even ordinary moments can hide deeply unsettling events.
