DNA SETBACK COULD DELAY ANSWERS FOR MONTHS The sheriff in Arizona has revealed a major setback in the investigation into Nancy Guthrie’s disappearance — and it involves critical DNA testing

Arizona Sheriff Reveals Nancy Guthrie Investigation Hit With DNA Setback That Could Take ‘Months’

 

Pima County Sheriff Chris Nanos has provided another update on the DNA evidence that was found in Nancy Guthrie’s home, and it’s sure to cause some more concern.

“Our lab tells us that there are challenges with it,” Nanos told Fox News, referencing the Florida lab. “The technology is moving so fast and in such a frenzy that they think some of this stuff will resolve itself just in a matter of weeks, months, or maybe a year.”

The outlet added that it’s “unclear whether the DNA recovered inside Guthrie’s has been useful for the investigation,” as the samples are from “more than one person, making it harder to run through national databases.”

Authorities Aren’t Ruling Out The Possibility Of An Accomplice

In a recent statement to PEOPLE, a County Sheriff’s Department spokesperson explained that they are not ruling out the possibility of an accomplice, as there’s no evidence the suspect was working alone.

“The sheriff has said all along that while investigators are working to identify the person seen on the doorbell video, they are not ruling out that that was the only person involved,” the spokesperson said.

This update was confirmed to Fox News by another spokesperson, who said, “…a spokesperson for the Pima Country Sheriff’s Department said investigators are looking into the possibility that the person may have had an accomplice.”

Former FBI Agent Provides Potential Motive Behind Nancy Guthrie Kidnapping

Former FBI agent Jonny Grusing spoke with Fox News, detailing how authorities should be looking into the possibility that this crime was due to a “personal grievance.”

“It’s hard to be an expert in human behavior because it’s so unique to that person,” Grusing said. “You know, I’m just trying to use the experiences of different cases and trying to apply any sort of logic to this in the hopes that someone from the public who has thought it might be someone they know whether it’s his family or whether now it’s a coworker or friend or associate or whatever, to put that one puzzle piece together that says, ‘Yes, and now I think it could be him.’”

“Is there a chance, since we don’t have audio, that he is either knocking on the door loudly or that he has pressed the ring doorbell, [that] he’s trying to get Nancy to answer the door, and he’s shielding himself from being seen as a masked person, so she will, in her confusion, open the door?” Grusing later added, asking rhetorically.
