TUCSON, Ariz. — Over a month has passed since the alarming disappearance of Nancy Guthrie from her Catalina Foothills residence.

Guthrie, aged 84, is the mother of Savannah Guthrie, a co-host on NBC’s “Today” show.

As the investigation stretches into its fifth week, the Pima County Sheriff’s Department, alongside the Federal Bureau of Investigation (FBI), has reallocated resources in the ongoing search, yet no arrests have been made nor has a suspect been publicly identified.

On Friday, February 6, 2026, FBI agents were seen canvassing the neighborhood near Nancy Guthrie’s Tucson home. Guthrie was last spotted on a Saturday night, and the investigation into her disappearance continues without pause.

According to sources, the investigation was reassigned on Monday to a specialized task force comprising Pima County homicide detectives and FBI agents. Despite repeated inquiries, Sheriff Chris Nanos has not offered any comments and has refrained from holding a press conference since February 5.

Investigators remain immersed in examining tens of thousands of tips and leads, alongside countless hours of video footage. The probe into DNA evidence is still active. Authorities have yet to disclose details about items linked to a possible suspect captured on Nancy’s Nest doorbell camera, apart from a distinctive Ozark Trail backpack.

They are also reportedly still looking into a Ring camera video taken on a back road out of Nancy’s neighborhood, about 2.5 miles from her home, which leads to East River Road, a major cross street.

The video, first obtained by Fox News Digital and provided to authorities last week, was recorded on a Ring camera roughly a seven-minute drive from Guthrie’s address — and it is still part of the investigation, Savannah’s network NBC reported Monday.

One of the vehicles it shows was recorded at around 2:36 a.m. on Feb. 1, which is roughly eight minutes after Guthrie’s pacemaker last synced with her iPhone, according to the sheriff’s timeline.

“I think this is the best lead probably since day one,” said retired Pima County Search and Rescue Commander Bob Krygier. He told Fox News Digital the footage is worth serious follow-up but cautioned it may ultimately prove unrelated.

“I think it’s a great little bit to follow up on. If I had to guess, I would say it’s probably not related,” he said, adding that investigators would likely review several weeks of footage to determine whether the cars follow normal overnight routines.

“It’s not just a road that you stumble upon,” he said. “You have to be very planned to go in there.”

Retired NYPD detective and national security expert Pat Brosnan reviewed the video with his team. He told Fox News Digital they believe the vehicle seen at 2:36 a.m. is a Kia Soul, based on its slanted roof, window design and rear-quarter glass. He also noted the vertical brake lights.

The combined reward is more than $1 million and has yet to be claimed.
