Federal investigators are reviewing a significant amount of previously unexamined digital data collected from security systems and smart devices at the home of Nancy Guthrie, the 84-year-old woman who vanished from her Tucson area residence more than a week ago and mother of “Today” show co-host Savannah Guthrie, authorities and law enforcement sources said Monday.
Agents from the Federal Bureau of Investigation joined local and county officers in analyzing information pulled from doorbell cameras, home security systems, and other connected technology in the Catalina Foothills neighborhood where Guthrie was last seen, Fox News Senior Correspondent Alicia Acuna reported.
Although some cameras on the property did not capture clear video, investigators can still extract what is known as “unseen data” — including timestamps, motion detection logs and signal interruptions — that may help reconstruct a timeline of events around the early morning hours of Feb. 1, when Guthrie disappeared.
According to officials, Guthrie’s doorbell camera was disconnected shortly after 1:45 a.m. on the night she went missing, and a motion detection signal was logged minutes later, followed by the disconnection of her pacemaker app from her mobile device. Those data points are now part of the FBI’s digital analysis as part of the ongoing investigation.
Fox News Digital previously reported that a security camera, which was mounted on the exterior of Guthrie’s home, had been removed from its wall bracket by Monday. This occurred while investigators continued searching the property, as recently as Friday morning.
Even when cameras fail to capture video of a suspect, investigators can still access what law enforcement calls “unseen data,” which is background information recorded by devices that do not trigger alerts to the homeowner, Fox noted.
Home security systems may not alert users when movement seems insignificant, but the technology can still log timestamps, analyze motion patterns, and detect signal interruptions that assist in reconstructing a timeline, according to Kurt “CyberGuy” Knutsson.
“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 was only designed to detect motion and did not record any video. This raises the possibility that an animal could have triggered the alert. Nevertheless, the pattern of digital disruptions has increased concerns that Guthrie did not leave her home voluntarily.
Investigators have repeatedly said the case remains active and that no suspects or persons of interest have been publicly identified. Authorities have also examined devices and other items removed from the property as they continue to follow leads.
The Pima County Sheriff’s Department, which is working with the FBI, urged anyone with information relevant to Guthrie’s disappearance to contact law enforcement. A reward remains available for information that leads to her safe return.
Family members, including Guthrie’s daughter, Savannah, have made public appeals for help and request that credible proof of life be provided by anyone holding relevant information.
A former NYPD inspector astonished Fox News hosts last weekend with a somber theory regarding the silence of Nancy Guthrie’s suspected kidnappers in ransom discussions: they are unable to provide proof of life.
“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 comment hit co-hosts Joey Jones and Tomi Lahren hard.
“Emmmm,” Jones groaned off camera. Lahren audibly sighed after hearing the prediction.
“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 said.
