Authorities are still questioning a motive behind the alleged abduction of Savannah Guthrie's mom, Nancy Guthrie. Pima County Sheriff Chris Nanos shared in an interview with the Daily Mail on Monday, February 16, that he believes Nancy, 84, was kidnapped rather than involved in a burglary that went wrong. "This is somebody who's disappeared from the face of the earth, and now we have a camera that says here's the person who did this," he explained, referring to the images released last week of the masked person seen on a camera outside Nancy's home.
