Savannah Guthrie told the potential kidnappers of her mother, Nancy Guthrie, on Saturday that the family is prepared to pay for her safe return, as the frantic search for the 84-year-old entered a seventh day.

“We received your message, and we understand. We beg you now to return our mother to us so that we can celebrate with her,” she said in a video posted on social media, flanked by her siblings. “This is the only way we will have peace. This is very valuable to us, and we will pay.”

It was not immediately clear whether the longtime host of NBC’s Today show was referring to a new message from someone who might have kidnapped Nancy Guthrie. The Associated Press reached out to the FBI and the Pima county sheriff’s department in Arizona seeking additional details.

Tucson TV station KOLD reported on Friday that it had received a message via email that was tied to the Guthrie case, the contents of which it could not disclose. The FBI said it was aware of a new message and was reviewing its authenticity.

Investigators think Nancy Guthrie was taken against her will from her home just outside Tucson last weekend. DNA tests showed blood on Guthrie’s front porch was a match to her, Pima county sheriff Chris Nanos has said. Authorities have not identified any suspects or ruled anyone out.

The sheriff said Friday that he was frustrated that a camera at Nancy Guthrie’s home was not able to capture images of anyone the day she went missing.

Investigators have found that the home’s doorbell camera was disconnected early Sunday and that software data recorded movement at the home minutes later. But Nancy Guthrie did not have an active subscription, so none of the images were able to be recovered.

The sheriff said Thursday that investigators have not given up on trying to retrieve camera recordings.

“I wish technology was as easy as we believe it is, that here’s a picture, here’s your bad guy. But it’s not,” Nanos told the AP. “There are pieces of information that come to us from these tech groups that say: ‘This is what we have and we can’t get anymore.’”

The sheriff also said he had no new information about the note to the TV station or other purported ransom letters sent to some media outlets, saying the FBI was handling that side of the investigation.

Meanwhile, concern about Nancy Guthrie’s health condition has grown because, authorities say, she needs vital daily medicine. She is said to have a pacemaker and has dealt with high blood pressure and heart issues, according to sheriff’s dispatcher audio on broadcastify.com.

“Her conditions, I would imagine, are worsening day by day,” Nanos said. “She requires medication. And I have no way of knowing whether they’re getting that medication to her.”
