"Today" show host Savannah Guthrie and her siblings are sending a new message to their mother's kidnapper in a third video released Saturday.

"We received your message and we understand," Savannah Guthrie said in the Feb. 7 video posted on Instagram. "We beg you now to return our mother to us so that we can celebrate with her. This is the only way we will have peace. This is very valuable to us, and we will pay."

The video is the latest in the saga of the missing Nancy Guthrie, who disappeared from her Tucson, Arizona, home a week ago. Police said they believed the 84-year-old was taken "against her will."

The Guthrie family issued an emotional plea for her return and said they were "ready to talk" to whoever may have taken her, in a video message released on Feb. 4. Nancy Guthrie's son Camron Guthrie in a second social media video on Feb. 5, addressed whoever wrote a ransom letter, which local police and the FBI are still working to assess.
