Volunteer Groups Seek Role in Search for Missing Tucson Woman After 100 Days

TUCSON, Ariz. — Authorities reported no new developments 100 days after the suspected abduction of 84-year-old Nancy Guthrie from her bedroom in Tucson. Volunteer groups have offered to assist in the search.

Guthrie disappeared from her home in the Catalina Foothills, an upscale suburb north of Tucson, in the early hours of Feb. 1. No signs of her have surfaced since. Doorbell video captured a masked man on her front steps, but no other suspects have been publicly identified.

"We just want to help, and we just want to find Nancy Guthrie," said Josh Gill, an organizer with the Louisiana-based nonprofit United Cajun Navy, which conducts volunteer search and rescue operations nationwide. "That's it."

Gill noted that his group recently helped locate missing 14-year-old Heaven Bruno in Louisiana after 67 days. A tipster who saw United Cajun Navy social media posts about the case reported a potential sighting to state police, who found the girl alive.

"They found her and reported it," Gill told Fox News Digital. He said tips from social media posts have aided other cases.

The Searching Mothers of Sonora group has also requested permission to join the effort.

Fox News Digital asked the Pima County Sheriff's Department last week for details on air and ground searches. A spokesperson declined to provide more than what investigators shared publicly on Feb. 2.

"We had a map in the initial press conference on the screens for the initial search," the spokesperson said. "I've been advised that we do not have any additional information to provide."

That map showed searches concentrated in Guthrie's immediate neighborhood, with colored lines marking ground efforts and rings indicating helicopter and plane coverage.

On Saturday, Pima County Sheriff Chris Nanos told Fox News Digital that investigators are getting closer to solving the case, without elaborating.

A private lab in Florida, which received DNA evidence from Guthrie's home in February, sent the sample to the FBI for advanced analysis after 11 weeks. The case marked its 14th week on Sunday.

Speaking with Fox News' Jonathan Hunt on Monday, Nanos said investigators continue working with labs and pursuing leads.

"There is really nothing new," he said.

United Cajun Navy sent a 41-page proposal to the sheriff's department, offering volunteers with dogs, drones and medical equipment. Gill said the group got no response despite offers to revise the plan and a Change.org petition.

"At this point, I can't imagine saying no to anyone offering help," said Bob Krygier, a retired Pima County Sheriff's Department lieutenant following the case. "Those are just extra feet on the ground that I don't have to pay, quite honestly."

Retired FBI supervisory agent Jason Pack said task force investigators likely continue progress out of public view.

"If investigators are still reviewing evidence, revisiting timelines and pushing forensic analysis forward, then the case is still moving, even if most of that movement happens far from television cameras and social media speculation," he told Fox News Digital. "And sometimes the most important breakthroughs happen quietly long before the public ever hears a word about them."
