Federal investigators are now sifting through a deep trove of digital data gathered from the Tucson home of Nancy Guthrie and nearby residences as the search for the missing mother of “Today” show anchor Savannah Guthrie enters a critical phase.
The FBI is analyzing information pulled from home security systems, smart devices and other connected technology in the quiet Catalina Foothills neighborhood where the 84-year-old vanished overnight more than a week ago, Fox News Senior Correspondent Alicia Acuna reported.
The digital sweep comes as visible evidence at the home continues to raise troubling questions. Fox News Digital previously reported that a security camera mounted on the exterior of Guthrie’s home as recently as Friday morning had been removed from its wall bracket by Monday while investigators continued searching the property.
Even when cameras fail to capture video of a suspect, investigators can still extract what law enforcement refers to as “unseen data,” background information logged by devices that never triggers an alert to the homeowner.
Home security systems may not notify users when movement appears insignificant, but the technology can still record timestamps, motion patterns and signal interruptions that help reconstruct 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.
Authorities believe that digital footprint could prove crucial in narrowing the window of Guthrie’s disappearance. The Pima County Sheriff’s Department previously released a timeline showing a series of disruptions in the early morning hours of Feb. 1.
According to investigators, Guthrie’s doorbell camera disconnected at 1:47 a.m. Motion was detected at 2:12 a.m., and her pacemaker app stopped syncing with her Apple devices at 2:28 a.m.
Officials have cautioned that the surveillance system detected motion only and did not record video, leaving open the possibility that an animal could have triggered the alert. Still, the clustering of digital disruptions has fueled concern that Guthrie did not leave her home voluntarily.
Investigators have repeatedly said there are no named suspects or persons of interest, even as the case has drawn national attention and federal resources. The FBI is now assisting the Pima County Sheriff’s Department alongside Border Patrol tactical units as the search expands beyond traditional ground efforts.
Law enforcement has returned to Guthrie’s property multiple times, removing items including a wired exterior camera, a broken floodlight and a blue Subaru SUV. On Sunday, detectives were seen opening a manhole and searching the home’s septic tank, though authorities have not disclosed what prompted that move or whether anything was recovered.
Blood was previously observed on the walkway outside the residence, and investigators have confirmed signs of forced entry. Guthrie’s cellphone, wallet, medication and vehicle were all found at the home.
The investigation has also been complicated by the emergence of alleged ransom notes sent to media outlets demanding millions of dollars in bitcoin for Guthrie’s release. The sheriff’s office has acknowledged it is investigating the messages but has not verified their authenticity.
Savannah Guthrie and her siblings released two public video pleas in recent days, confirming they had received a message from whoever took their mother and begging for her safe return. In the most recent appeal, Savannah said the family understands the message and wants to celebrate with their mother again.
Nancy Guthrie requires daily medication and has limited mobility, factors investigators say make the case especially urgent. Her pacemaker data, now part of the FBI’s digital analysis, may provide additional clues about when she was taken.
As physical leads remain scarce, authorities are increasingly relying on the invisible trail left behind by disrupted signals, disconnected devices and unseen data points, hoping the digital evidence will succeed where traditional searches have so far fallen short.
