Savannah Guthrie has issued an urgent appeal on social media for evidence her mother remains alive following her kidnapping.

The NBC "Today" show presenter stated on Wednesday, 4th February, that her family stands prepared to engage with those detaining their mother, referencing a ransom demand reportedly mentioned in press coverage, The Mirror reports.

"We are ready to talk. However, we live in a world where voices and images are easily manipulated" Guthrie said. "We need to know without a doubt that she is alive and that you have her. We want to hear from you and we are ready to listen. Please reach out to us."

In an emotional address, Savannah and her sister Annie spoke directly to their 84 year old mother. "Mommy, if you are hearing this, you are a strong woman. You are God's precious daughter, Nancy. We believe and know that even in this valley, he is with you. Everyone is looking for you, Mommy. Everywhere. We will not rest. Your children will not rest until we are together again," Savannah said through tears.

"Mama, mama, if you're listening, we need you to come home. We miss you," Annie added.

Police investigators are working to reconstruct the timeline surrounding Nancy's vanishing.

"Is there somebody out there who's kidnapping elderly people in the middle of the night, every night?" Pima County Sheriff Chris Nanos said on Tuesday. "We don't believe that's the case. We believe Nancy was taken from her home against her will."

The sheriff confirmed that footage from certain cameras had been obtained, though he refrained from providing specifics, stating: "That's all been submitted and we're doing our best with the companies that own those cameras or built those cameras."

As enquiries progress, Nano's office revealed they are interviewing anyone who had contact with Nancy over the previous weekend, although no suspect or person of interest has been named. The property where she resided by herself has been returned to the family.

Given evidence of forced entry at the Catalina Foothills residence and Guthrie's restricted mobility, authorities do not believe she departed voluntarily. A sheriff's dispatcher communicating with officers during Sunday's search noted that she suffers from high blood pressure, has a pacemaker and experiences heart problems, according to audio from broadcastify.com..

Jim Mason, a veteran commander of a search-and-rescue team in Maricopa County who is not participating in the hunt for Guthrie, explained that desert landscape can complicate searches for missing individuals. He noted the challenge of scanning areas thick with mesquite trees, cholla cactus and other desert vegetation, which makes navigating through them problematic.

It has been reported that multiple media organisations received alleged ransom demands on Tuesday which they passed to investigators. The sheriff's department has confirmed it is treating the correspondence and other leads seriously but refused to elaborate further.

Nancy was last seen at 9.45pm on Saturday after being dropped off at home by her family following dinner. She was reported missing when she failed to show up at church on Sunday, according to the sheriff's department.

Meanwhile, Victory Church in Albany, New York, on the opposite side of the country, has announced a $25,000 reward for information leading to the discovery of Nancy Guthrie. "Me and my wife, we watch Savannah every single morning. We've heard of her faith. We've heard of her mum's faith. And she's got such a sweet spirit," Pastor Charlie Muller stated.

For the third consecutive day, the "Today" show has led with news of Guthrie's disappearance, but Savannah has been absent from the anchor's desk. NBC Sports has confirmed that the host will not be covering the 2026 Milan Cortina Winter Olympics "as she focuses on being with her family during this difficult time."

The White House revealed that President Donald Trump had a phone conversation with Savannah Guthrie on Wednesday.
