FBI shifts command post in Nancy Guthrie search, dismisses Ring camera video

Chanley Painter reports live from Tucson on the ongoing search for Nancy Guthrie, an 84-year-old grandmother. The FBI has moved part of its intelligence command post to Phoenix but assures that personnel remain on the ground in Tucson. Authorities are dismissing a new Ring camera video from a nearby home showing cars around the time of Guthrie's disappearance, while simultaneously processing thousands of hours of other video for leads, including footage of a man working on security cameras at Guthrie's home.
