The search for Nancy Guthrie enters a new and critical phase. The 84-year-old mother of NBC Today show host Savannah Guthrie has now been missing for over five weeks after vanishing from her Tucson-area home on February 1, 2026, in what authorities believe was a forced abduction. Today, new details are emerging about the FBI tip line, a dedicated task force, and growing speculation about a suspect.

Nancy Guthrie Update: FBI Tip Line Calls Are Tapering Off

On March 5, a Fox News reporter posted on X that the FBI had issued a statement confirming that tips related to the Nancy Guthrie case have "tapered" off after an initial surge. Investigators continue urging anyone with information to call the tip line at 1-800-CALL-FBI.

The FBI tip line was created in early February and generated tens of thousands of calls in the opening weeks of the investigation. That initial surge gave detectives weeks' worth of leads to chase down — which is why the recent drop in incoming tips is considered a significant development in the case.

Experts caution against reading the slowdown as a negative sign. CNN senior law enforcement analyst Josh Campbell has noted that being overwhelmed with tips that go nowhere can actually slow an investigation, as sorting fact from fiction takes critical time away from finding Nancy.

Nancy Guthrie Task Force: FBI and Pima County Join Forces Full-Time

A new joint FBI and Pima County Sheriff's Department task force has been formed specifically for the Nancy Guthrie case. Four detectives and a sergeant have been relocated to the FBI's Tucson office to work solely on this investigation going forward.

Before the task force was created, nearly every single detective in the Pima County Sheriff's Office had been assigned to the case — a resource level that was unsustainable given other ongoing crimes in the county. The restructured team signals a long-term, focused commitment from both agencies.

A retired FBI agent, Jason Pack, called the FBI's return to Nancy Guthrie's neighborhood for fresh door-to-door canvassing a "good sign," telling Fox News that it means the case is clearly "still in motion."

Evidence Update: Gloves, DNA, and Miles of Surveillance Footage

While public attention has focused on a pair of black gloves found roughly two and a half miles from Nancy's Tucson home, authorities have quietly been testing additional gloves discovered significantly farther away — up to seven miles from the scene.

The DNA on the closer pair of gloves was traced back to a person who works at a nearby restaurant, and Pima County Sheriff Chris Nanos confirmed that individual "has nothing to do with the case." The more distant gloves are still under active DNA analysis.

Sheriff Nanos also revealed the staggering scale of the video review underway. Authorities are combing through thousands of hours of traffic camera footage from the surrounding area, in addition to Ring camera footage showing the masked suspect the night Nancy was taken.

Suspect Profile: What Investigators Know So Far

A forensic review of doorbell camera footage shows the suspect appears to be a man between 5-foot-9 and 5-foot-10 with an average build, carrying a black 25-liter Ozark Trail Hiker Pack backpack.

A forensic expert and retired police sergeant, Betsy Brantner Smith, told Fox News Digital that it is possible police already have solid suspects in mind but are withholding that information from the public to protect the integrity of the investigation. She added that the suspect, or suspects, may have returned to Nancy Guthrie's residence.

Sheriff Nanos told NBC News that investigators are "definitely closer" to resolving the case, while also acknowledging there are still several key things they have not yet been able to identify — including a vehicle caught on a Ring camera around 2 a.m. the night Nancy disappeared.

Reward, Savannah Guthrie, and What Comes Next

Savannah Guthrie left Arizona on March 5 to visit colleagues at the Today Show. She plans to resume co-hosting duties, though a specific return date has not yet been confirmed.

The Guthrie family is offering a $1 million reward, which Savannah has stressed "can be paid in cash." The FBI is separately offering an additional $100,000 reward for information leading to Nancy's recovery. Anyone with information is urged to call 1-800-CALL-FBI immediately.
