Nancy Guthrie Case: Sheriff Says 'New Possible Ransom Text Message' Is 'Not Credible' Nearly 8 Months After Savannah's Mom Disappeared

Nancy Guthrie's disappearance has taken another turn nearly eight months after the 84-year-old mother of Today host Savannah Guthrie vanished from her Arizona home.

Police announced on September 28 that they were investigating a 'new ransom note'; however, they have since said that it is 'not credible.'

"On Monday, September 28, the PCSD/FBI Guthrie Task Force was made aware of a new possible ransom text message related to the Nancy Guthrie investigation," the Pima County Sheriff's Department said in a statement shared Tuesday, September 29. "After further review, investigators determined the text message is not credible."

The department added, "Investigators will continue to review reported messages for credibility and investigate any potential attempts at extortion."

"The Nancy Guthrie investigation remains active and ongoing," the statement continued.

The latest development comes after multiple alleged ransom notes surfaced following Nancy's disappearance.

In July, PCSD released two notes in hopes that the community could help "break the case," Sheriff Chris Nanos said in a video.

One of the earlier notes reportedly demanded cryptocurrency in exchange for Nancy’s release, while another claimed she had died.

Chris previously explained why investigators chose to release the earlier notes.

"We just saw what was being said, and we felt like we needed to put something out that's really accurate, and this was the time," Nanos explained.

He added, "Investigators felt like there's a number of pieces of information in these notes that it just might jog someone to say, 'I've heard that,' or [recognize] the wording, the style of the writing. It might jog somebody to think about who would've written this, how was this done?"

"My investigators, we look at it, and clearly there's things in there that are very concerning to our investigative team. So we hope that by releasing the actual note we'll get some response from the community," the PCSD sheriff continued.

Nancy was last seen on January 31 before she was reportedly taken from her Tucson, Ariz., home in the early morning of February 1.

Her family reported her missing that day after she failed to go to a church service, which has launched a months-long investigation.

One of the two eerie July random notes read, "We did not fully grasp the seriousness of her physical conditions. We never intended to hurt her; that was not our intention. She perished shortly after she was taken. We believe it was heart-related."

"She is buried in nature now," the note continued. "Nothing you could have done could have changed the outcome. We want your family to know this and hope you all can find peace. We are truly sorry."
