Nancy Guthrie update: Retired detective reveals what he thinks could lead to ‘big break’ in case

Amid the search for Nancy Guthrie, a former Modesto Police Department detective turned law enforcement consultant has said that tracking could lead to a “big break.” Jon Buehler said in a conversation with NewsNation’s Brian Entin that tracking cars in the area of Nancy’s home, through surveillance cameras or GPS data, may expose a possible suspect.

Buehler also suggested checking if anyone ever searched for Nancy’s address on Google.

‘There might be something in there that we’re waiting on’

“If somebody ever plugged her address into a Google search for a Google Maps or whatever, if they did a reverse keyword search on that because those records are maintained for a period of time, to see any random person that would have typed in her address that had a reason to do it and then you’d contact that person and find out why did you put that address,” he explained.

Buehler said that based on what the seasons people offer, they could either be eliminated or examined for potential involvement.

Buehler said that he does not believe Nancy survived the attack, but that the case is still solvable. He said that a critical lead may have been buried in the enormous number of tips that have been provided.

“When tips come in on a case like Nancy Guthrie’s, they’re prioritized as best they can, but you still don’t know for sure if they’re prioritized correctly, and so there might be something in there that we’re waiting on, that could break it wide open,” Buehler said.

Pima County Sheriff Chris Nanos previously acknowledged in an interview with People that the Guthries must be “frustrated” with the lack of answers. However, it seemed certain that answers would come.

“My team, I’ve said all along, they’re gonna solve this,” he said. “I fully 100% believe that. … When you have the best minds of the country working on problems, I think they’re gonna solve them. It just takes a while.”
