With the apparent ransom deadline looming Monday evening, Today show coanchor Savannah Guthrie made yet another heartfelt plea for help in finding her missing 84-year-old mother, Nancy Guthrie.

“We need your help,” Savannah Guthrie said in a video posted to social media. “Law enforcement is working tirelessly around the clock, trying to bring her home, trying to find her. She was taken and we don’t know where.”
