TUCSON, Arizona: Popular US morning news anchor Savannah Guthrie posted a video message on Wednesday addressing anyone who might be holding her missing elderly mother, presumed abducted from her Arizona home this week, pleading for them to open a line of communication. “We need to know without a doubt that she is alive and that you have her. We want to hear from you and we are ready to listen. Please, reach out to us,” the co-host of NBC’s “Today” show said in the video message posted to Instagram.
