Savannah Guthrie Believes Missing Mother Nancy Guthrie 'Is Still Out There' as She Pleads for Help in Heartbreaking Video

Savannah Guthrie believes her missing mother, Nancy Guthrie, is still alive more than one week after her disappearance.

"I wanted to come on and just share a few thoughts as we enter into another week of this nightmare," Savannah, 54, expressed in a heartbreaking video posted via Instagram on Monday, February 9, as she pleaded for the public's help.

The NBC anchor began the nearly two-minute clip by thanking the public for their concern following the news of her mother's disappearance, as she was last seen on January 31.

"Just want to say first of all, thank you so much for all of the prayers and the love that we have felt, my sister and brother and I, and that our mom has felt, because we believe that somehow, someway, she is feeling these prayers," she said. "We believe our mom is still out there. We need your help."

Savannah explained law enforcement was working "tirelessly around the clock" to try and find her mother.

"She was taken and we don't know where. We need your help," she said while shaking her head. "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, hear anything that seems strange to you, that you report to law enforcement."

The journalist called it an "hour of desperation" as she closed out the video.

Nancy was reported missing on February 1 after a friend noticed the 84-year-old missed her regular Sunday church service. She was last seen by a family member entering her home at 9:30 p.m. the night before, after having dinner with daughter Annie Guthrie.

The Pima County Sheriff's Department later confirmed Nancy's home was being treated as a crime scene after "concerning evidence," such as blood, was found.

Authorities immediately considered the possibility of an abduction, as Nancy had "no cognitive issues" but struggled with her mobility.

Savannah, Annie and their brother, Camron Guthrie, have responded to their mother's alleged kidnapper via a few videos after a ransom letter demanded millions in cryptocurrency.

"We received your message and understand. We beg you now to return our mother to us so we can celebrate with her. This is the only way we will have peace. This is very valuable to us, and we will pay," the group said in the video.
