The disappearance of 84-year-old Nancy Guthrie in Tucson remains under active investigation after new forensic and digital evidence emerged from the night she went missing.
She was last seen returning home on January 31, 2026, after dinner with family. Authorities say her son-in-law has been interviewed but not arrested or charged.
Evidence of a possible struggle and unusual pacemaker data have raised concerns, and the search is ongoing.
