Savannah Guthrie has filmed an emotional video demanding proof her missing mother Nancy "is still alive"

In the video, Savannah, who was sat next to her brother and sister, said: "We too have heard the reports about a ransom letter in the media. As a family, we are doing everything that we can. We are ready to talk.

"However, we live in a world where voices and images are easily manipulated. 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."

She added of Nancy: "She is 84 years old. Her health, her heart is fragile. She lives in constant pain. She is without any medicine. She needs it to survive. She needs it not to suffer."

Savannah went on to reflect on all the support the family has been given since news of Nancy's disappearance broke, saying: "On behalf of our family, we want to thank all of you for the prayers for our beloved mom, Nancy.

"We feel them and we continue to believe that she feels them too. Our mom is a kind, faithful, loyal, fiercely loving woman of goodness and light. She is funny, spunky, and clever.

"She has grandchildren that adore her and crowd around her and cover her in kisses. She loves fun and adventure. She is a devoted friend. She is full of kindness and knowledge. Talk to her and you'll see."

Addressing Nancy herself, Savannah added: "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. We speak to you every moment and we pray without ceasing and we rejoice in advance for the day that we hold you in our arms again. We love you."

The video was posted on Instagram with the caption: "Bring her home".

Savannah has also been given support by US President Donald Trump, who wrote in a post on Truth Social: "I spoke with Savannah Guthrie, and let her know that I am directing ALL Federal Law Enforcement to be at the family's, and Local Law Enforcement's, complete disposal, IMMEDIATELY.

"We are deploying all resources to get her mother home safely. The prayers of our Nation are with her and her family. GOD BLESS AND PROTECT NANCY!"

Prime County Sheriff Chris Nanos previously suggested that Nancy "did not leave" her property alone.

Speaking at a news conference on Monday (02.02.26), he said: "We do in fact have a crime scene. We do in fact have a crime. She did not leave on her own. We know that."

He added: "Taken against her will includes possible kidnapping or abduction."

Nanos explained that law enforcement officials have been reviewing video footage from cameras at Nancy's home and has implored her neighbours to "go through their Ring cameras" as well.

The sheriff also explained that Nancy had "no cognitive issues" and would not have been able to leave the property alone because of mobility issues.

Nanos said: "This is not dementia-related. She's as sharp as a tack. The family wants everyone to know that this isn't someone who just wandered off.

"She couldn't walk 50 yards by herself."

The sheriff has asked members of the public to come forward if they have any information relating to the case.
