Questions are mounting in the disappearance of Nancy Guthrie, as new details and eyewitness theories suggest the possibility that more than one person may have been involved the night the 84-year-old vanished.
Guthrie, the mother of Savannah Guthrie, has not been seen since early February. Authorities say signs of a violent confrontation were discovered outside her home, fueling concerns that she may have been forcibly taken.
