Nancy Guthrie Update Today: Wi-Fi Jammer Theory Emerges, Woman's Body in Phoenix Not Linked — Day 36

The search for Nancy Guthrie has entered its 36th day with no confirmed leads on her whereabouts. New developments this weekend include a chilling Wi-Fi jammer theory, a woman's body found near a Phoenix canal, and a dedicated FBI task force now working the case full-time.

Nancy Guthrie Case Background: What Happened on February 1

Nancy Guthrie, the 84-year-old mother of NBC Today co-anchor Savannah Guthrie, was reported missing from her home in the Catalina Foothills area of Tucson, Arizona, on February 1, 2026. Evidence recovered at the residence indicated she had been taken against her will. Bloodstains found at the scene were confirmed to be Nancy's. Multiple ransom notes of undetermined origin demanded payment in cryptocurrency, with two deadlines that had passed by February 9.

Nancy was last seen around 9:45 p.m. on January 31, after having dinner with her daughter Annie. She was reported missing the next morning after she failed to show up to watch a livestreamed church service, as she did most Sundays.

Wi-Fi Jammer Theory — The Biggest New Development This Week

The FBI questioned Guthrie's neighbors about whether they experienced internet disruptions on the night she went missing. Several residents confirmed their connections glitched that night.

An antenna-like device spotted in the pocket of the masked suspect captured on Guthrie's doorbell camera has 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.

Pima County Sheriff Chris Nanos declined to confirm whether the suspect used a Wi-Fi jammer, but confirmed that investigators are looking into every angle related to surveillance video.

Woman's Body Found Near Phoenix Canal — No Link to Nancy Guthrie

A woman was found dead alongside a canal in Phoenix, Arizona, on Saturday, March 7. Pima County authorities confirmed they had not been informed of any link between that case and Nancy Guthrie's disappearance.

The discovery briefly sent shockwaves across social media, but investigators were quick to separate the two cases. The Nancy Guthrie investigation remains centered on Tucson and surrounding areas.

FBI Task Force Formed — Investigators Say They Are "Closer"

A dedicated joint task force between the FBI and Pima County Sheriff's Department has been formed. Four detectives and a sergeant have been moved to the FBI's Tucson office, where they will work full-time solely on the Nancy Guthrie case.

Pima County Sheriff Chris Nanos told NBC News that he and his team are operating under the belief that Guthrie is still alive and are pursuing thousands of leads. "I think the investigators are definitely closer," he said.

FBI Tip Line Has "Tapered" — Investigators Still Urging Public Help

The FBI confirmed on March 5, 2026, that tips to the case's tip line have "tapered" after an early surge of tens of thousands of calls. Investigators stressed they are still urging anyone with information to call. A full-time Nancy Guthrie case task force has been formed, and the case is not considered cold despite fewer incoming leads.

Experts noted that a reduction in incoming tips is normal, and that a flood of unverified leads can actually slow investigations by overwhelming detectives with false information to process.
