Arizona sheriff points to possible crime scene in Nancy Guthrie disappearance

Authorities say 84-year-old Nancy Guthrie, Savannah Guthrie’s mother, is missing in Tucson, with signs at her home indicating she didn’t leave voluntarily. The sheriff described the scene as a potential crime scene and did not rule out foul play, as drones, search dogs, volunteers and Border Patrol assist the investigation; Nancy Guthrie, who needs daily medication, was last seen Saturday night. Savannah Guthrie is in Arizona and thanked supporters as the Today show opened with the update.
