We believe our mom is still out there," Savannah said in an Instagram video uploaded on February 9. "We need your help. Law enforcement is working tirelessly around the clock, trying to bring her home, trying to find her." The Today host continued, "She was taken, and we don't know where, and we need your help. So, I'm coming on just to ask you, not just for your prayers, but no matter where you are, even if you're far from Tucson, if you see anything, you hear anything, if there's anything at all that seems strange to you, that you report to law enforcement."
