Savannah Guthrie makes emotional plea as abduction deadline nears: 'Hour of desperation'

"Today" show co-host Savannah Guthrie on Monday shared a new video message and direct appeal to the public as the search continues for her abducted mother, 84-year-old Nancy Guthrie.

Guthrie posted a new video on Instagram, thanking people for their prayers and support for her family, including her mother. Nancy went missing from her home in Tucson, Arizona, sometime overnight between Jan. 31 and Feb. 1. The last message, posted by the family on Saturday, had appeared to be a direct appeal to a potential ransom or abductor, and the message this week has appeared to differ in tone as the second ransom deadline was reportedly hours away.

“I wanted to come on and just share a few thoughts as we enter into another week of this nightmare," Guthrie said.

"We believe that somehow, someway that she is feeling these prayers and that God is lifting her in this moment and in this darkest place. We believe our mom is still out there," she said. "We need your help. 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. And we need your help," Guthrie said. "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, if you hear anything, if there's anything at all that seems strange to you, that you report to law enforcement. We are at an hour of desperation and we need your help.”

Pima County Sheriff's Department and FBI investigators had continued to search for Nancy Guthrie. Anyone with information was urged to contact the tip lines: 1-800-CALL-FBI or 520-351-4900.
