Gayle King: 'Somebody knows something' in Nancy Guthrie disappearance

Gayle King, 71, urged anyone with information to come forward while speaking at Michael Rubin’s Fanatics Super Bowl party in San Francisco on Saturday. "Somebody knows something," she said. "Now is the time for that somebody to speak up." She had earlier called the situation "unimaginable." On Thursday's "CBS Mornings," King grew emotional discussing Savannah Guthrie's family.

She recalled a social-media video in which Savannah and her siblings pleaded, "Mommy, we're all looking for you," and called the alleged kidnapping "so frightening and so disturbing." "It's so, so, so scary to me," King added, noting how close Savannah was to her mother.

Nancy, 84, was last seen Saturday evening after being dropped off at her Tucson, Arizona, home following a family outing and was reported missing on Sunday after failing to attend church. Authorities said they are treating her home as a crime scene and believe she was "taken from the home against her will," calling the investigation active and ongoing.
