Two weeks after Nancy Guthrie mysteriously disappeared, her daughter Savannah is pleading for her safe return. "I wanted to come on. It's been two weeks since our mom was taken, and I just wanted to come on and say that we still have hope. We still believe, and I wanted to say to whoever has her, or knows where she is, that it's never too late and you're not lost or alone," the Today show host, 54, said in a video shared via Instagram on Sunday, February 15.
