Man says he was questioned about Nancy Guthrie's disappearance before being released

Authorities investigating the disappearance of Nancy Guthrie detained a man in Arizona who says he was questioned for hours Tuesday night before being released. The man told several media outlets that he had nothing to do with last week’s disappearance of Guthrie, the 84-year-old mother of “Today” show host Savannah Guthrie. The development came just hours after the FBI released images of a masked person on Nancy Guthrie’s porch the night she went missing near Tucson. Authorities have not said what led them to stop the man and had not confirm he was released. The Pima County Sheriff’s Department says it also searched a location Tuesday night in a city where the man lives near U.S.-Mexico border.
