'We will pay,' Savannah Guthrie says in desperate video plea to potential kidnappers of her mother

TUCSON, Ariz. — 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 Arizona resident has 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.''

The ''Today'' show host was referencing a message that was sent to the Tucson-based television station KOLD on Friday afternoon, according to Kevin Smith, a spokesperson for the FBI office in Phoenix.

KOLD said it received an email related to the Guthrie case on social media that day but declined to share specific details about its contents as the FBI conducted its review.

The station was one of multiple press outlets that received alleged ransom letters during the week. At least one letter made monetary demands and established Thursday evening and the following Monday evening as deadlines.

In a news conference Thursday, law enforcement officials declined to affirm that the letters were credible but said all tips were being investigated seriously. They also said one letter referenced Nancy Guthrie's Apple watch and a specific feature of her property.

The video released Saturday was the third this week that pleaded with potential kidnappers.

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.

''It is concerning, it's actually almost disappointing, because you've got your hopes up,'' Nanos told The Associated Press in an interview. ''OK, they got an image. ‘Well, we do, but we don't.'''

President Donald Trump, speaking on Air Force One on Friday, said the investigation was going ''very well.''

Investigators return to scene

They were back in Nancy Guthrie's neighborhood on Friday.

The sheriff's department posted on social media to say access was restricted to the road in front of the home to give investigators space. Journalists staked out there were directed to move.

The Catalina Foothills Association, a neighborhood group, told residents in a letter that authorities were resuming searches in the area immediately.

''I know we all stand together in our collective disbelief and sadness and greatly appreciate your willingness to speak with law enforcement, share camera images and allow searches of your properties,'' the association president said in the letter.

''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 is 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 have 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.''

The kidnapping has captured the attention of Americans, including Trump, who said he was directing federal authorities to help investigate.
