A man detained by police for questioning in the disappearance of Nancy Guthrie has been released. Meanwhile, investigators hope that images of a masked person on her Arizona porch still will bring tips from the public to help solve her apparent abduction. The man told several media outlets early Wednesday that he was released after several hours and had nothing to do with Nancy Guthrie. She's the mother of NBC “Today” co-anchor Savannah Guthrie. The man said he makes deliveries in the Tucson area. Investigators say they searched a location in Rio Rico, a city south of Tucson.
