No detail too small as family searches for missing mom Nancy Guthrie

As the search for 84-year-old Nancy Guthrie stretches into its eighth week, her family asked for Tucson-area residents to revisit camera footage, notes and conversations from the days surrounding her disappearance. Guthrie, who lives in the Catalina Foothills and is the mother of "

Today" show co-host Savannah Guthrie, was last seen Jan. 31 after spending the evening with family a few miles away, according to previous reporting by The Arizona Republic.

“It’s possible a member of this community has information that they do not even realize is significant,” the family said in a statement shared with Tucson-based television station KVOA on March 21. Her family reported her missing the next morning after she did not show up to a friend’s house for a virtual church service. The Pima County Sheriff’s Department has described the case as an active investigation but has released few new details in recent weeks.

Investigators continue analyzing “material from laboratories as well as images and videos captured by cameras” but declined to comment on the status of that analysis, department spokesperson Angelica Carrillo said in a March 13 news release. The family’s renewed plea urged residents to think back to specific time frames.

“We hope people search their memories, especially around the key timelines of Jan. 31 and the early morning hours of Feb. 1 as well as the late evening of Jan. 11,” the statement said.

“No detail is too small. It may be the key.” Here's the latest on the investigation into Nancy Guthrie's disappearence.

What we know about the investigation Authorities have said Guthrie’s disappearance is being investigated as a suspected abduction. On Feb. 10, the FBI released video and photos of a masked man approaching Guthrie’s home the night she went missing after extracting footage from her Google Nest doorbell camera, despite her not being subscribed to a service that stores security video, according to prior reporting by The Republic. The FBI estimated the man is between 5 feet 9 inches and 5 feet 10 inches tall with an average build.

He was seen wearing a black 25-liter Ozark Trail Hiker Pack backpack. Law enforcement has reviewed hundreds of hours of neighborhood footage and canvassed residents, asking whether they noticed internet service disruptions the night Guthrie disappeared, NBC News reported earlier this month. Authorities have also analyzed physical evidence collected from the scene and surrounding areas.

Black gloves initially believed to be connected to the case were later determined through DNA testing to belong to a restaurant worker not connected to Guthrie’s disappearance, the Sheriff’s Department said in a March 4 statement. Other DNA evidence remains under analysis, Carrillo said in prior updates. Pima County Sheriff Chris Nanos has said investigators believe the abduction appeared targeted but said in a 12News interview that they are not “100% sure” and have urged residents to remain vigilant.

Nanos has faced growing scrutiny, including reporting by The Arizona Republic that found he misrepresented aspects of his disciplinary history and work record in a sworn deposition and on his public résumé. The Pima County Board of Supervisors was set to discuss his work history, and a recall effort has also been launched against him. Ransom messages and reward Tucson television stations and the celebrity gossip outlet TMZ received ransom notes following Guthrie’s disappearance.

Investigators have not said whether those notes were authenticated or provided proof that Guthrie was alive, according to previous reporting. Federal authorities arrested a Southern California man suspected of sending fake ransom-related communications to the family. His case remained pending in federal court.

Savannah Guthrie announced a $1 million reward for information leading to her mother’s return or recovery. The FBI has also offered a $100,000 reward. Call for tips Law enforcement continued to ask anyone with information about Nancy Guthrie’s disappearance to contact 1-800-CALL-FBI, 520-351-4900, 88-CRIME or submit tips at tips.fbi.gov.

In their March 22 statement, the Guthrie family emphasized that even small observations could matter. “We desperately ask this community for renewed attention to our mom’s case,” the statement said. “Please consult camera footage, journal notes, text messages, observations or conversations that in retrospect may hold significance.”
