TUCSON, AZ — Pima County sheriff’s officials said Friday they are still pressing ahead in the Nancy Guthrie missing person investigation, nearly nine months after she was kidnapped from her Tucson home. The department said it continues to work with the Nancy Guthrie Task Force on DNA analysis in an effort to move the case forward.

Investigators also said they traveled to Florida earlier this month to meet with lab scientists about what else could be done. The agency said several ideas were discussed and that its partners remain focused on solving the case.

The update came as detectives again asked the public not to discount even the smallest detail. Officials said a minor tip could still prove important as they continue to review information and work with federal partners.

How Guthrie disappeared from her Tucson home

Nancy Guthrie, the mother of NBC journalist Savannah Guthrie, was kidnapped from her home in Tucson on Feb. 1. Authorities said she was last seen shortly before 10 p.m. on Jan. 31 after a relative dropped her off at her home in the Catalina Foothills neighborhood.

Despite the passage of time, investigators have not publicly identified a suspect or person of interest. A masked man was captured on Guthrie’s Ring doorbell camera, but officials have not said that image has led to an arrest or clear identification.

In the days after the disappearance, Pima County Sheriff Chris Nanos told reporters that Guthrie did not leave voluntarily. His statement underscored investigators’ view that she was taken against her will.

Ransom notes have shaped the investigation since July

Authorities released two ransom notes in July that were tied to the kidnapping. The first, sent Feb. 2, said Guthrie was unharmed and demanded that $4 million in cryptocurrency be delivered for her release.

The second note, sent four days later on Feb. 6, claimed Guthrie had died shortly after the kidnapping. Law enforcement released both notes publicly in late July and said they appeared to be written in a distinctive style.

Investigators asked anyone who recognized the writing patterns to come forward with information. They said the notes could help identify who was involved or connect the case to other evidence already collected.

Investigators say tips increased after notes were made public

After the ransom notes were released, authorities said they saw an increase in tips related to the case. That response appears to have given investigators more material to review, even if no breakthrough has been announced publicly.

Late last month, the Pima County Sheriff’s Department said the Guthrie task force had been made aware of a possible new ransom note. Officials said detectives were also looking into social media comments about it and working to determine whether the information was credible.

The department has not said whether the possible new note is authentic or whether it changes the direction of the investigation. For now, investigators are treating it as one more lead to examine.

Task force remains focused on DNA and laboratory review

The sheriff’s department said its latest work with the Nancy Guthrie Task Force includes DNA analysis, suggesting investigators still believe forensic testing may offer a path forward. The trip to Florida to meet with lab scientists was part of that effort.

Officials did not describe exactly what kind of material is being tested or what scientists suggested during the meeting. But the department made clear that it is continuing to pursue scientific review alongside traditional investigative work.

The case has remained open because detectives have not been able to identify a suspect or explain all of the evidence that has surfaced so far. The combination of digital evidence, ransom notes, witness information and laboratory work has kept the investigation active.

Authorities again urge anyone with knowledge to call

As the case drags on, investigators continue to ask the public for help. The sheriff’s department said no tip is too small and emphasized that even a seemingly minor detail could matter.

Anyone with information is asked to call 1-800-CALL-FBI. People who want to remain anonymous can contact 520-88-CRIME.

Officials have made repeated appeals for information since Guthrie’s kidnapping, and the latest update shows the investigation is still active. The department says it is continuing to work with its partners while it reviews new information and tests possible leads.
