Four months after the disappearance of Nancy Guthrie, investigators may be preparing to deploy new technological tools in what remains one of the most closely watched unsolved kidnapping cases in the country.
Sources familiar with the investigation told Fox News Digital that the FBI has been discussing the use of additional technology as part of its ongoing effort to locate Guthrie and identify whoever is responsible for her suspected abduction from her Tucson home. Officials declined to provide specifics about the tools under consideration, leaving outside experts to speculate on where investigators may be focusing their efforts.
Morgan Wright, CEO and founder of the National Center for Open and Unsolved Cases, believes any breakthrough is likely to come from advances in data analysis rather than traditional investigative methods.
“The solution to this case is going to be, I think, something technical, something that they come up with — new ways of analyzing data,” Wright told Fox News Digital.
He suggested three likely areas where investigators could see progress: video forensics, signal analysis, and blockchain tracing.
Video forensic technology could allow investigators to enhance existing footage or uncover details that were previously impossible to identify, including information about the suspect or the vehicle believed to have been involved. Signal analysis could focus on cell phone records, location data, or advertising technology identifiers that may reveal who was present in the area at critical times. Blockchain analysis, meanwhile, could potentially help trace ransom or extortion attempts connected to the case and determine whether those communications were legitimate.
“If I’m going to put it into three buckets, I’d say it’s going to come out of one of those three buckets,” Wright said.
Based on the evidence made public so far, Wright also believes investigators are likely searching for a single perpetrator rather than a larger group. He noted that only one individual has appeared in the recovered surveillance footage and that no one has attempted to claim the reward, which now exceeds $1.2 million.
“I don’t know that there’s anything else to indicate a second person,” he explained.
Wright pointed to surveillance footage showing a masked individual attempting to obscure a camera before ultimately removing it. In his view, the suspect may have been more concerned with concealing a vehicle than hiding an already-covered face.
“The blood trail stops at the edge of the driveway,” he noted. “So we know there was a car.”
The investigation has already featured the use of sophisticated technology. Authorities previously deployed a Bluetooth detection system from a helicopter in hopes of locating signals connected to Guthrie’s pacemaker. Investigators have also achieved a significant breakthrough by recovering footage from Nest cameras despite the absence of a cloud subscription and the disappearance of the physical recording device before police arrived.
That recovered footage reportedly captured a masked man at Guthrie’s residence on the night she vanished as well as during a separate visit weeks earlier.
As investigators continue to pursue new leads, the Guthrie family is urging anyone with information to contact the FBI at 1-800-CALL-FBI. A combined reward of more than $1.2 million remains available for information that helps solve the case.
