Nancy Guthrie update: Retired detective says suspect may have left a major clue; 'could break it wide open;

Despite doorbell camera footage of a masked suspect and DNA evidence sent to the FBI lab in Quantico, no suspects have been named. Now, a retired detective is sharing what he thinks could finally break the case open.

Buehler believes the person behind the crime may have made a simple digital mistake. He told NewsNation that if the suspect searched for Nancy Guthrie’s address on Google Maps or another navigation service before the alleged abduction, those records could still exist and potentially help investigators identify them.

“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 told NewsNation.

Buehler also said newer vehicles with built-in tracking technology could provide another clue. Investigators may be able to identify vehicles that were near Nancy Guthrie’s home around the time she disappeared and then determine whether the drivers had a legitimate reason to be there. People such as delivery drivers could be ruled out, while others could face closer scrutiny.

Buehler suggested the perpetrator may have been someone who had previously visited Nancy’s home in a work capacity and realized her connection to a wealthy television personality. As he told NewsNation, “Any tradespeople that maybe were doing plumbing repair or electrical repair, anybody who was delivering furniture, anything that came up where somebody could see her as a source of ransom because of the connection with Savannah and Savannah’s notoriety.”

“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.

He also noted that fear can keep cases cold for years. “We had a random murder that went 11 years unsolved, and it was only because the one person that could give us the information was afraid to come forward, and it took 11 years for them to get over that fear,” he said.

Additionally, he said he believes only one person carried out the abduction, pointing to the large reward offered in the case. “But because of that reward thing that really sticks with me, that’s some pretty expensive loyalty to have for somebody else,” he said. “People that have independent wealth are not doing crimes like this.”

The investigation remains active as the Guthrie family continues to wait for answers. The Guthrie family is still offering a $1 million reward for information, and the FBI is separately advertising a $100,000 reward.

Additionally, Savannah Guthrie has spent $500,000 of her own money on private investigators to help search for her mother.

The source told US Sun that, “She [Savannah] is not prepared to stop looking for her mother. She feels that depending only on the official investigation is not enough anymore- that’s why she’s investing so heavily in private investigators and outside specialists.”
