Guthrie family pleads for answers as mother remains missing
Savannah Guthrie tearfully described her family’s agony in the first interview since her mother, Nancy Guthrie, disappeared in Tucson on Feb. 1; investigators found blood on the porch and DNA on a glove, initially linked to a suspect but later attributed to a restaurant worker, and the FBI is seeking a man about 5 ft 9 in to 5 ft 10 in as the case remains active with no arrests; Guthrie plans to return to the Today show.
