Authorities in Tucson, Arizona, continue to explore leads in the disappearance of 'Today' anchor Savannah Guthrie's 84-year-old mother, Nancy, who's been missing under mysterious circumstances since Sunday, Feb. 1, in what's being treated as a suspected kidnapping. ET speaks with Pima County sheriff Chris Nanos and CBS's national news correspondent Jonathan Vigliotti for the latest, as new details come to light. Plus, former NewsNation anchor and 'Drop Dead Serious' host Ashleigh Banfield sheds light on her shocking reporting that one of Nancy's family members — her son-in-law, Tommaso Cioni, who had an hours-long meeting with police — may be a 'prime suspect,' despite investigators saying they have no persons of interest at this time.
