As the search for Nancy Guthrie enters its seventh week with no suspect identified, federal investigators have broadened their scope in the Catalina Foothills neighborhood of Tucson — while newly recovered surveillance images from her home have produced no meaningful new leads, sources confirmed Wednesday.

FBI Expands Interviews Beyond Residents

A law enforcement source told News4 Tucson (KVOA) that FBI agents have returned to the Catalina Foothills neighborhood and expanded their interview process to include people who are not regular residents of the area — specifically landscapers and construction workers who work near Nancy Guthrie's home. This marks the first confirmed report that agents are specifically targeting non-resident workers as part of the widened canvass.

The source was careful to stress that the broadened effort does not represent a step backward in the investigation, according to News4 Tucson. The Pima County Sheriff's Department separately confirmed that investigators continue to analyze evidence, including laboratory results and camera footage.

Surveillance Images Reviewed, Nothing Suspicious Found

CBS News confirmed additional details Wednesday about a set of surveillance camera images recovered in recent weeks from Guthrie's Tucson home. According to law enforcement sources cited by CBS News, the images came from two cameras: one fastened to a fence and focused on the back of the house, and a second showing the driveway and the front of the garage door. The footage captured family members, landscapers, and pool workers in the weeks leading up to the abduction.

Investigators found nothing suspicious in the reviewed images. Critically, no footage from these two cameras showed the suspect already captured on a separate front door camera — the only known images of the perpetrator, which the FBI released publicly on February 10.

Expert Warns Investigation Growing 'Much Harder'

With more than 45 days elapsed and the latest camera review yielding no actionable intelligence, a retired FBI supervisory special agent offered a sobering assessment. Lance Leising told CBS News the situation points to "a lack of meaningful leads."

"It becomes much harder to keep the investigation going, keep it current and fight for new leads," Leising said.

Leising noted that DNA recovered from the scene is still being analyzed using forensic genetic genealogy — a technique that previously helped identify Bryan Kohberger, convicted in the murders of four University of Idaho students in 2022. However, he cautioned that the process "takes a while," explaining that investigators may need to independently look into multiple individuals who share DNA with the same family before narrowing in on a suspect.

Despite the challenges, Leising offered a measure of cautious hope, noting that the investigative silence from authorities could be meaningful. "I'd like to be hopeful — and I'm sure the family is incredibly hopeful — that the silence is because they're on to something," he told CBS News. "They just need to investigate harder."

Reward Billboards and Tip Lines Keep Pressure On

In a visible push to keep public attention on the case, 88-CRIME erected a new billboard along Interstate 10 in the Tucson area offering a $102,500 reward for information leading to Nancy Guthrie's safe return. That amount is separate from the $1 million reward announced by the Guthrie family and the FBI's standing $100,000 reward — bringing the combined total to more than $1.2 million for anyone with actionable information.

88-CRIME confirmed it has received 2,445 anonymous tips through its phone line, website, and P3 Tips mobile app, according to the Sunday Guardian Live. The FBI previously reported receiving more than 25,000 tips between February 1 and March 2, with more than 30,000 calls and tips logged within the first two weeks of Guthrie's disappearance. CBS News also noted that over 1,500 additional potential leads came into the FBI following the family's announcement of the $1 million reward — though it has been nearly three weeks since the family last made a public appeal.

Sheriff Recall Effort Continues

Meanwhile, the political fallout surrounding the investigation continues to build. A formal recall effort against Pima County Sheriff Chris Nanos — launched on March 12 — remains underway, with organizer Daniel Butierez citing the department's handling of the Guthrie investigation as a central reason, according to Sunday Guardian Live. Butierez has 120 days from March 12 to collect more than 120,000 verified signatures needed to trigger a recall election.

Sheriff Nanos addressed the recall effort this week, stating, "It's the right of the people. We'll always honor the will of the people, and that's what makes Democracy," according to Sunday Guardian Live. The recall comes amid additional pressure on Nanos, including reported discrepancies in his work history and a lawsuit filed against him and his department by an inmate.

Background

Nancy Guthrie, 84, is the mother of NBC's TODAY show co-anchor Savannah Guthrie. She was last seen at her Tucson-area home on January 31, 2026, and is believed to have been abducted overnight. The FBI released doorbell camera footage on February 10 showing a masked individual at her home the night of her disappearance. Now 46 days into the investigation, no suspect has been publicly identified.

What to Watch Next

Investigators and the public are now watching for any development from the ongoing forensic genetic genealogy analysis of DNA recovered at the scene — a process that experts say could take considerable time but has historically cracked high-profile cold cases. The expansion of FBI interviews to non-resident workers in the Catalina Foothills area could also produce new leads. Whether authorities schedule a public news conference in the coming days — their first in more than a month — will itself be a signal about the state of the investigation.
