More than 21 weeks have pᴀssed since Nancy Guthrie was believed to have been abducted, yet investigators are still searching for answers. During that time, the FBI, working alongside Google, recovered crucial Nest doorbell footage, thousands of tips have been reviewed, and two men were detained and later released without charges. Despite those developments, Guthrie’s whereabouts remain unknown.

Herman Weisberg, a former NYPD detective who now serves as managing director of the New York-based investigative firm SAGE Intelligence, believes the case could still be solved by a single piece of information from the public.

Speaking to Fox News Digital, Weisberg said investigations of this scale demand persistence and patience. He noted that detectives may spend days following thousands of leads, but one unexpected phone call could provide the breakthrough they have been waiting for.

“You might be on your 7,000th call and your 15th cup of coffee,” Weisberg said. “But the 7,001st call could be the one that contains the critical piece of information.”

Now more than 150 days into the investigation, with updates from authorities becoming increasingly rare, Weisberg believes the intense public attention surrounding the case could ultimately work in investigators’ favor.

“The awareness that comes with a high-profile crime like this should be an advantage in solving it,” he explained.

As an example, Weisberg pointed to the investigation into Gabby Peтιтo’s disappearance, where members of the public reviewing their own dashcam footage ultimately provided investigators with the evidence needed to locate her remains at a remote campground in Wyoming.

Although he expected modern technology to play a larger role in solving the Guthrie case, Weisberg acknowledged that digital evidence does not always lead investigators directly to the truth.

“I’m actually pretty shocked that this case didn’t come down to technology,” he said.

He compared the investigation to the Idaho murders involving Bryan Kohberger, where technological evidence proved instrumental in identifying the suspect. However, he emphasized that every case unfolds differently.

“Technology was the case-breaker there, but anything can happen in a case like this,” Weisberg said. “If this was committed by a single offender, investigators lose one of their biggest advantages—having someone else who can come forward and point the finger.”

Based on his own ᴀssessment, Weisberg believes the crime may have spiraled out of control from the very beginning, preventing investigators from taking advantage of opportunities that might normally exist during the early stages of a case.

At the same time, he cautioned that the public should not ᴀssume investigators have run out of leads. He believes authorities may be much closer to solving the mystery than they have publicly revealed.

“They could be working on a lead right now,” Weisberg said.

Even so, investigators and Guthrie’s family continue to urge anyone with information to come forward. More than $1.2 million in reward money is currently being offered, including a $1 million reward from Guthrie’s family for information that leads to her recovery.
