Authorities searched a Rio Rico home after detaining a man during a traffic stop. A woman who spoke to CNN said FBI agents told her they had received a tip that Nancy Guthrie was inside; she identified herself as the detainee’s mother‑in‑law and said officers executed a court‑authorized search and questioned her son‑in‑law, whom she denied was involved. Guthrie, 84, remains missing after being taken from her Tucson home. The FBI and Pima County Sheriff’s Office are leading the investigation, released surveillance images of a person of interest, and are offering a $50,000 reward for information as authorities continue searching.
