TUCSON, Ariz. — The urgent investigation into the apparent kidnapping of 84-year-old Nancy Guthrie continues to fascinate and concern the public a week after the mother of 'Today' show host Savannah Guthrie was reported missing from her home in Tucson, Arizona.

In a poignant social media video released Saturday, Savannah Guthrie made a heartfelt appeal to the kidnappers, asserting that the family is prepared to pay for her mother's safe return. Surrounded by her siblings, she stated, “This is the only way we will have peace. This is very valuable to us, and we will pay.”

According to an FBI spokesman, the plea was in response to a message sent to local television station KOLD on Friday, the details of which remain undisclosed pending investigation.

Investigators believe Nancy was taken from her home against her will last weekend. Further complicating matters, DNA tests confirmed that blood found on her front porch matched her DNA, raising the urgency of the search.

A number of news outlets have received potential ransom letters throughout the week, with at least one letter demanding a monetary figure and establishing strict deadlines for payment. While law enforcement has not confirmed the letters' authenticity, they are taking all tips and information seriously as the situation unfolds.

The sheriff's office has not provided updates recently, leading some to speculate about the current status of the investigation.

The emotional toll of Nancy's disappearance is palpable, with candles lit outside her home as a symbol of hope. The White House confirmed that President Donald Trump spoke to Savannah Guthrie, expressing belief in the existence of strong clues regarding Nancy's whereabouts.

Regarding health concerns, authorities have expressed increasing worry for Nancy's well-being as she relies on daily medication, has a pacemaker, and has previously dealt with significant health issues such as high blood pressure.

The family remains hopeful for a safe resolution, having released multiple appeals to the public and potential kidnappers throughout the week.
