Nancy Guthrie Update: Ex-FBI Agent Thinks Guthrie Family Should be 'Upset' Over DNA Evidence Reveal

Nancy Guthrie, the mother of Today host Savannah Guthrie, remains missing nearly three months after she disappeared from her home in the Catalina Foothills of Tucson, AZ.

Earlier this week news broke that a private Florida lab that works with the Pima County Sheriff’s Department sent a DNA sample to the FBI in recent weeks. The FBI is now reportedly using new "advanced technology" to conduct advanced analysis on the DNA sample to see if it can lead to Guthrie’s kidnapper.

The FBI revealed the DNA evidence is not, in fact, new, but was initially sent to Florida instead of the FBI.

“There is no new DNA evidence in the Nancy Guthrie case. The FBI requested this material over two months ago,” an FBI official told ABC News. “The Pima County Sheriff’s Office sent it to a private lab in Florida. Eleven weeks later, that lab has now transferred an original hair sample to the FBI Laboratory for testing. We remain fully committed to this investigation.”

Former FBI Agent 'Upset' With DNA Evidence Decision

Former FBI agent Jennifer Coffindaffer, who has been covering the Guthrie disappearance from the beginning, suggested the FBI would have always had the "advanced technology" and questioned sending the DNA sample to a different lab.

"The fact that they're saying the FBI has this advanced technology, they would've always had it," she said. "So that should really irk everyone that the sample didn't go there because they would have always had the advanced technology and expertise."

Coffindaffer commented on the initial "excuse" as to why the DNA sample was sent to a lab in Florida saying "it was based on them having the profiles established and all that, you know, this being imminent in terms of time and urgency and that's why they kept it – that made a lot of sense, to be honest."

However, once the "advanced technology" comment was revealed, Coffindaffer made it clear she's not on board.

"But knowing that they had that technology, that should really have the Guthrie family and anybody who cares about justice for Nancy Guthrie upset, because that is not tracking at all," she said plainly.

The Pima County Sheriff’s Department previously addressed the DNA evidence being handed over to the FBI.

“PCSD has worked with the FBI since the beginning of the Guthrie investigation,” the PCSD said. “This is not new information. The private lab we utilize in Florida continues to share information with the FBI lab and other partner labs across the country. DNA analysis remains ongoing.”

Coffindaffer revealed the DNA evidence could take months to yield a result.
