Nancy Guthrie stepped out of her son-in-law’s car and into the dark — and was never seen again. Just minutes earlier, she had been laughing over dinner with family in Tucson.

Investigators say the evening ended normally. Tommaso Cioni, her son-in-law, drove the 84-year-old home, watched her walk safely toward her front door, and left believing the night was over.

Hours later, concern set in when Nancy failed to answer calls. Worry quickly escalated into panic, prompting deputies to check her home.

Inside, officers found no signs of forced entry or struggle. The house was quiet and undisturbed, creating more questions than answers about what happened next.

With no immediate evidence of a break-in, investigators began focusing on Nancy’s final moments — the short drive home, the goodbye, and the brief window of time afterward.

Savannah Guthrie, along with her sister Annie and Tommaso, has been left replaying those ordinary moments repeatedly, searching for meaning in what once felt routine.

Authorities say there are still no suspects and no clear trail. Every possibility remains open, from confusion to foul play, as the investigation continues.

For the family, hope rests in those last quiet minutes. Somewhere within them, they believe, lies the clue that could explain Nancy’s disappearance and bring her home.
