TUCSON, Ariz. (CIVITAS) — The urgent effort to locate Nancy Guthrie, the 84-year-old mother of 'Today' show anchor Savannah Guthrie, has entered a critical phase. A week after she was reported missing from her home in Tucson, authorities are pursuing all leads in what they suspect is a kidnapping case.

In a heart-wrenching video released on social media, Savannah, flanked by her siblings, directly addressed potential kidnappers: We received your message. This is the only way we will have peace. We will pay for her safe return. The plea underscores the family's desperation as they navigate this troubling situation.

According to FBI representatives, Savannah's comments were in reference to a message sent to a local television station, which they are currently investigating. The content of the message remains undisclosed to the public while law enforcement reviews its credibility.

Sheriff Chris Nanos revealed that evidence, including DNA tests, confirmed that blood found on Nancy’s porch matched hers, indicating she may have been taken against her will. Ransom letters have reportedly been sent to media outlets, demanding payments by specified deadlines, raising alarms regarding their authenticity.

As the search continues, social media has been flooded with tips and speculation from concerned citizens, and candles have been lit near Nancy’s home as signs of support and hope. President Donald Trump even reached out to Savannah last week, expressing confidence in the investigation, stating that investigators have strong clues.

Authorities are particularly worried about Nancy’s health as she requires daily medication, has a pacemaker, and has faced heart issues in the past. Savannah's emotional videos, which marked the third plea this week for her mother's safe return, illustrate the urgency and gravity of the situation.

As public interest in the case grows, the sheriff's department has emphasized their commitment to resolving this distressing disappearance.
