TUCSON, Ariz. (AP) — Savannah Guthrie, the co-host of NBC's 'Today' show, has made an emotional plea for public assistance in the search for her missing mother, Nancy Guthrie. In a heartfelt Instagram video, Savannah disclosed the family’s despair and explained that their attempts to communicate with possible abductors have been unsuccessful, heightening their sense of urgency.

In recent videos, the family has offered a ransom for her safe return, but Savannah's latest message resonated with a tone of desperation, marking a shift towards encouraging the public to assist law enforcement agencies in gathering any potential clues regarding her mother’s whereabouts.

The FBI confirmed Monday that they have not detected any ongoing communications between the Guthrie family and any suspected kidnappers, more than a week after Nancy’s disappearance. As of now, no suspects or people of interest have been identified, prompting the FBI to establish a command post that operates around the clock in cooperation with crisis management specialists.

According to Savannah, the family keeps faith that Nancy is alive and aware of the outpouring of support from the community. She was taken and we don’t know where, and we need your help, Savannah stated in her video, urging people across the country to remain vigilant and report any sightings or tips regardless of distance from Tucson.

The case has captivated the nation, drawing attention from prominent figures, including former President Donald Trump, who reached out to Savannah, as well as countless online communities actively discussing potential leads. The FBI is utilizing digital billboards in major cities across Texas, California, Arizona, and New Mexico, offering a $50,000 reward for information that could solve this distressing case.

In the days following Nancy's disappearance, several alleged ransom letters have emerged, making demands and setting deadlines that families are currently addressing. Law enforcement agencies are approaching these letters with caution, verifying their authenticity, while thousands of tips have flooded dedicated law enforcement hotlines.

Health concerns for Nancy, who requires daily medication linked to her heart condition, have been voiced due to the time elapsed since her disappearance. Savannah expressed the family's willingness to pay whatever it takes for her mother's safe return, stating, This is the only way we will have peace. This is very valuable to us, and we will pay.

Authorities believed that Nancy was forcibly taken from her home just outside of Tucson, as she was reported missing on February 1st after failing to attend church. Indicative evidence, including blood found at the scene matched to Nancy, has led law enforcement to intensify their search efforts.

As the investigation continues, neighbors and community members rally outside Nancy's home, providing support and hope for the family during this challenging time. The Pima County Sheriff's Department remains committed to following leads and enhancing their investigative process to identify those responsible for Nancy Guthrie's disappearance.
