Sheriff's department gives update on Nancy Guthrie case 9 months after kidnapping

The Pima County Sheriff’s Department gave an update on the Nancy Guthrie missing person’s case on Friday, saying the department continues to work with the Nancy Guthrie Task Force on DNA analysis in an effort to advance the case. 

"Earlier this month, investigators traveled to Florida to meet with lab scientists to see what more could be done to advance this case," the department wrote in an X post. "A number of ideas were discussed, and we continue to work with all our partners to solve this case." 

The law enforcement agency reminded the public that no tip is too small. 

"Even the smallest piece of information could be critical to this investigation," the department said. 

NANCY GUTHRIE CASE: UNCLAIMED $1.2M REWARD SUGGESTS 'VERY SMALL CIRCLE' OF SUSPECTS, RETIRED FBI AGENT SAYS

Guthrie, NBC journalist Savannah Guthrie’s mother, was kidnapped from her home in Tucson, Arizona, on Feb. 1. 

The 84-year-old was last seen shortly before 10 p.m. local time on Jan. 31 after a relative dropped her off at her home in the Catalina Foothills neighborhood of Tucson.

Authorities have struggled to identify a suspect or person of interest in her disappearance, despite a masked man appearing on Guthrie's Ring doorbell camera.

Pima County Sheriff Chris Nanos, in the days following Guthrie's disappearance, confirmed that she was taken, telling reporters during a news briefing, "She did not leave on her own. We know that."

Authorities had previously released two ransom notes related to Guthrie's kidnapping in July.

The first, which was sent on Feb. 2, reported that Guthrie was unharmed and demanded that her captors be sent $4 million in cryptocurrency to secure her release.

The second, sent four days later on Feb. 6, said Guthrie had died shortly after she was kidnapped.

Authorities released the ransom notes in late July, noting they were written with a unique writing style, asking anyone who recognizes the patterns to share any information with PCSD and the FBI.

Late last month, investigators said they had been made aware of a possible new ransom note in relation to Guthrie's disappearance.

"The PCSD/FBI Guthrie Task Force was recently made aware of a new possible ransom note related to the Nancy Guthrie investigation," PCSD wrote in an X post in late September. 

"Investigators are also aware of social media comments regarding the note and are looking further into the information to determine its credibility," the post concluded.

Anyone with information is asked to dial 1-800-CALL-FBI or, to remain anonymous, call 520-88-CRIME.
