FBI Examines Newly Discovered Digital Evidence in Nancy Guthrie Disappearance

Federal investigators are now combing through a newly uncovered cache of digital evidence tied to the disappearance of Nancy Guthrie, the 84-year-old Arizona woman who vanished from her Tucson-area home more than a week ago. Guthrie is the mother of Today show co-host Savannah Guthrie, a fact that has drawn national attention to the case.

According to law enforcement sources, agents with the Federal Bureau of Investigation have joined local and county authorities to review data collected from multiple security systems and smart devices inside and around Guthrie’s residence in the Catalina Foothills neighborhood. Fox News Senior Correspondent Alicia Acuna reported that the analysis includes information pulled from doorbell cameras, home surveillance systems, and other connected technology at the property.

While some of the cameras at the home failed to capture usable video footage, investigators are relying heavily on what is known in law enforcement circles as “unseen data.” This includes metadata such as timestamps, motion detection records, and signal interruptions — digital breadcrumbs that can help reconstruct a detailed timeline of events surrounding the early morning hours of February 1, when Guthrie was last seen.

Authorities have confirmed that Guthrie’s doorbell camera was disconnected shortly after 1:45 a.m. that night. Minutes later, a motion detection alert was logged, followed by the sudden disconnection of Guthrie’s pacemaker app from her mobile device. Investigators say these data points are now central to the FBI’s digital forensic analysis.

Fox News Digital previously reported that an exterior security camera mounted on Guthrie’s home had been physically removed from its wall bracket by Monday, even as investigators continued searching the property as recently as Friday morning.

Experts note that even in the absence of recorded video, modern home security systems quietly collect extensive background data. That information, though invisible to homeowners, can provide crucial insight into suspicious activity. Fox News reported that these systems often log events without sending alerts if the movement appears insignificant.

Home security expert Kurt “CyberGuy” Knutsson explained that such data can be invaluable.

“Cameras facing the Guthrie house right now show very little activity, but I promise you there’s an enormous amount of activity going on on the digital side,” Knutsson said.

Officials have cautioned that the surveillance system involved was designed solely to detect motion and did not record video, leaving open the possibility that an animal could have triggered at least one alert. Still, investigators say the unusual pattern of digital disruptions has intensified concerns that Guthrie did not leave her home of her own free will.

Law enforcement has emphasized that the investigation remains active and ongoing. No suspects or persons of interest have been publicly named, and authorities continue to analyze devices and other materials removed from the property while pursuing multiple leads.

The Pima County Sheriff’s Department, working alongside the FBI, has urged anyone with relevant information to contact law enforcement. A reward is still being offered for information that leads to Guthrie’s safe return.

Family members, including Savannah Guthrie, have issued repeated public appeals for help and have requested that anyone with credible information provide proof of life.

Adding to the unease surrounding the case, a former NYPD inspector offered a grim theory during a Fox News appearance last weekend, suggesting that the absence of ransom communication may signal something far worse.

“Well, you’re elusive on the communications because you know you’re going to be asked for proof of life that you can’t provide,” retired NYPD Inspector Paul Mauro said on Fox News’s “The Big Weekend Show.”

The remark visibly stunned co-hosts Joey Jones and Tomi Lahren.

“Emmmm,” Jones groaned off camera. Lahren audibly sighed.

“I feel like they’ve been playing games with the details in the house and all of that,” Mauro said. “They probably planned for the idea that they could provide proof of life, and now they find themselves in a spot where, ‘We can’t. And so what do we do? Now we gotta bargain for something else. We gotta bargain to give back something else.’”

“That’s my read with the limited facts we have, hoping against hope I’m wrong,” Mauro added.
