A man detained by police for questioning in the disappearance of Nancy Guthrie has been released while 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.

Authorities are expected to release a surveillance photo showing a potential subject in the investigation into the disappearance of Nancy Guthrie, the mother of “TODAY” co-anchor Savannah Guthrie, according to two senior law enforcement officials.
