(TJV NEWS) As USA Today reported, the search for the missing mother of “Today” show anchor Savannah Guthrie has stretched into a second week, with federal and local authorities continuing an intensive investigation in southern Arizona.

Nancy Guthrie, 84, was reported missing from her home outside Tucson on Sunday, Feb. 1. The Pima County Sheriff’s Department is leading the case and is working closely with the FBI, which has deployed additional resources to the area. Investigators are also examining several alleged ransom messages that were sent to news organizations, though officials say no suspects or persons of interest have been identified so far.

In a new video released Monday, Feb. 9, Savannah Guthrie made another emotional appeal for help, describing the family’s growing desperation. “We are at an hour of desperation,” she said, urging anyone with information to come forward.

The Feb. 9 message marked the fourth public video statement from the Guthrie family. In earlier pleas, Savannah Guthrie appeared alongside her brother and sister, directly addressing whoever may be responsible for their mother’s disappearance. Looking into the camera, she said the family is begging for Nancy Guthrie’s safe return and emphasized they are willing to pay to have her back. “This is the only way we will have peace,” she said in one of the appeals.

According to law enforcement, one of the alleged ransom communications referenced two deadlines, one of which fell on Monday, Feb. 9. Despite that, the FBI said it is not aware of any ongoing contact between the Guthrie family and anyone claiming to have abducted Nancy Guthrie.

In a statement issued the same day, FBI spokesperson Brooke Brennan said agents, analysts and professional staff have been working nonstop for more than a week in an effort to reunite Nancy Guthrie with her family. Brennan added that the bureau has not identified any suspects or persons of interest and has not seen evidence of continued communication with potential kidnappers.

The FBI has established a 24-hour command post in Tucson, bringing in crisis management specialists, analytical support teams and investigators from field offices across the country. Still, authorities stress that public assistance remains critical.

Anyone with information related to the case is urged to contact the Pima County Sheriff’s Department at 520-351-4900 or the FBI at 1-800-CALL-FBI (1-800-225-5324).
