Nancy Guthrie Update Today: Day 37 — Damaged Utility Box Discovered Near Her Home, Pacemaker Heart Attack Warning, Glove DNA Ruled Out

Day 37 in the search for Nancy Guthrie brings three significant new developments — a damaged utility box found around the corner from her Tucson home is now under investigation, a medical expert has raised alarming concerns about her pacemaker risk during the 2 a.m. abduction, and a promising glove DNA lead has officially been ruled out. The 84-year-old mother of Today co-anchor Savannah Guthrie has now been missing for 37 days, and while the FBI confirms tip line calls have tapered, a dedicated full-time task force is actively narrowing the investigation.

Damaged Utility Box Around the Corner: New Evidence Under Review

The newest physical evidence in the case emerged over the weekend. On Sunday, March 8, Fox News Digital reporter Michael Ruiz posted an update revealing that investigators are aware of a damaged utility box discovered around the corner from Nancy Guthrie's home. A Pima County Sheriff's Department spokesperson confirmed: "It is being reviewed as part of the ongoing investigation. At this time, we do not have any additional details to release."

An antenna-like device spotted in the pocket of the masked suspect captured on Guthrie's doorbell camera has already prompted serious questions about whether it was a signal jammer capable of causing a neighborhood-wide internet outage. One neighbor told investigators his Ring camera history is mysteriously marked "not available" from the night Guthrie disappeared. The damaged utility box, located in the same immediate neighborhood, could be directly connected to that theory — or it could be entirely unrelated. Investigators are not speculating publicly.

Medical Expert Warning: Pacemaker Plus 2 AM Abduction Equals Deadly Risk

A sleep specialist examining Nancy Guthrie's suspected early-morning abduction warned that the 84-year-old pacemaker patient could have faced immediate mortal danger when abruptly awakened around 2 a.m., plunging her disoriented brain into confusion that could trigger cardiac arrest. On Nancy Grace's Crime Stories podcast, sleep expert Pat Byrne explained how sleep inertia — the groggy transition from deep slumber to consciousness — left Guthrie vulnerable during the critical minutes when doorbell footage captured a masked intruder tampering with her camera.

Guthrie's known heart condition and pacemaker placed her at "very high risk of a heart attack" when violently roused, according to Byrne. Scientific research documents elderly patients — even without cardiac history — suffering sudden cardiac events from abrupt awakenings. "That concerned me immediately," the sleep doctor emphasized, noting Guthrie's medical vulnerability multiplied the sleep inertia threat during those first confused minutes after the doorbell intruder appeared. The expert's warning has renewed pressure on investigators to accelerate the search timeline.

Glove DNA Ruled Out: Restaurant Worker Identified, Not Connected to Case

One lead that seemed promising earlier in the week didn't work out. According to Pima County Sheriff Chris Nanos, the DNA on a glove that was found near the scene was traced back to a person who works at a nearby restaurant and has nothing to do with the case. Officials previously said the gloves appeared to look like the same gloves worn by the masked suspect seen in surveillance footage at Nancy Guthrie's home. On February 13, authorities sent the gloves off for testing at a private Florida laboratory, and the DNA analysis results came back this week showing the gloves are not related to the case.

Wi-Fi Jammer Theory: Neighborhood Internet Glitches Confirmed on Night of Abduction

Three homeowners who spoke to investigators said they were either asleep or not home at the time of Guthrie's abduction and couldn't say if they had internet issues. But one couple who lives adjacent to Guthrie said they did notice a glitch with one of their Ring cameras that night. They have four Ring cameras on their property, and the one closest to Guthrie's home said "not available" when they went to look for footage from the overnight hours on the day of the abduction. Their other cameras, which are farther away from her home, did not have that issue. They said they had never seen the "not available" warning before and said it seems "uncanny" that it happened exactly during that timeframe.

FBI Tip Line Update: Calls Have Tapered — But That May Be Good News

The FBI told Fox News reporter Matt Finn that tips related to the case have "tapered" — down from the tens of thousands of calls received in the case's earliest weeks. Investigators continue urging anyone with information to call 1-800-CALL-FBI.

Experts noted that a reduction in incoming tips is normal at this stage, and that a flood of unverified leads can actually slow investigations by overwhelming detectives with false information to process. A full-time Nancy Guthrie case task force has been formed — four detectives and a sergeant from the Pima County Sheriff's Department have been moved to the FBI's Tucson office — and the case is not considered cold.

Savannah Guthrie Returns to Today Show Studio

Savannah Guthrie, who has been on leave from the Today show and in Arizona with her family, visited the New York studio this week and said she plans to return to her post. "While she plans to return to the show on air, she remains focused right now supporting her family and working to help bring Nancy home," a spokesperson said. The $1 million reward offered by the Guthrie family can be paid in cash. Anyone with information is urged to call 1-800-CALL-FBI immediately.
