A Tucson neighbor says that weeks before Nancy Guthrie vanished, a motion sensor and floodlight at his home suddenly activated late at night, revealing a man standing in the yard who ran off on foot when spotted. The neighbor later described the encounter to media, and because the home is reportedly less than ten minutes from Nancy’s, investigators are reviewing whether it could connect to the timeline of her disappearance. Nancy, 84, was last seen late Saturday, January 31, 2026, after being dropped off at her home. When she didn’t appear at church the next morning—something her family says was completely out of character—relatives checked the house and contacted authorities. Since then, the focus has shifted from a broad missing-person search to an investigation with growing urgency, driven by her age, limited mobility, and need for daily medication.

As public attention intensified, the Pima County Sheriff’s Office urged people not to spread unverified rumors and emphasized that no official “person of interest” has been named. In public remarks, Sheriff Chris Nanos said investigators processed the home and believed a crime had occurred, describing it as a confirmed crime scene. Savannah Guthrie and her siblings also released an emotional video appeal, asking anyone with real information to come forward and stressing they’re willing to communicate—but only with proof that their mother is safe, noting how easily images and audio can be manipulated today. The family’s message was simple: they won’t stop looking, and they want Nancy home alive.
