TUCSON, Ariz. (AP) — Savannah Guthrie, prominent host of the 'Today' show, made a desperate call for public assistance in finding her mother, Nancy Guthrie, who has been missing for more than a week. In her latest emotional video posted on Instagram, Savannah expressed grave concern for her mother’s well-being and highlighted the critical need for the public to stay vigilant.

Savannah, alongside her family, has been actively posting videos asking for help, even offering a ransom for Nancy's return. However, the tone of her messages has evolved, shifting towards encouraging public cooperation with investigators as ongoing attempts to contact the suspected abductors have yielded no results or evidence of Nancy being alive.

The FBI has reported that they have not confirmed any dialogue between Nancy's family and the suspected kidnappers. As of Monday, they have not identified any suspects while maintaining a 24-hour command post to coordinate the investigation.

“We believe she is out there and hearing everyone’s prayers,” Savannah stated, focusing on hope amidst the turmoil. She urged anyone across the nation, regardless of their distance from Tucson, to be alert for any clues concerning her mother’s whereabouts.

As the investigation unfolds, authorities express growing concerns about Nancy's health given her need for daily medication, including a pacemaker and treatment for high blood pressure. The mysterious situation has captivated many, including officials at the highest levels, as the FBI has begun utilizing digital billboards in multiple states to garner public help.

Hints of ransom have surfaced as well, with numerous news outlets reporting the receipt of letters demanding payment, although law enforcement has yet to endorse the credibility of these communications. Investigators stress that any tips received are being taken seriously, as thousands of calls have flooded their tip lines.

As Savannah and her family continue to navigate this challenging ordeal, they remain hopeful for Nancy’s safe return. The heartfelt messages from the Guthrie family serve as an anchor of hope and humanity amidst an unsettling situation that grips not just their personal lives, but the attention of the entire nation.
