Nancy Guthrie Update: Former FBI Agent Raises Concerns Over DNA Handling, Says Guthrie Family Should Be 'Upset'

Nancy Guthrie, 84, has been missing since Sunday, Feb. 1, and investigators continue working to solve the case. Weeks into the search, no arrests have been made and she has not been located.

On April 16, ABC News reported that DNA recovered from Guthrie's Arizona home had been handed over to the FBI after it was tested for several weeks at a lab in Florida. Reports indicated that the FBI would use "advanced technology" to test said DNA. Now, former FBI agent Jennifer Coffindaffer is weighing in.

"The fact that they're saying the FBI has this advanced technology, they would've always had it," she said in a live video posted to X on Saturday, April 18. "That should really irk everyone that the sample didn't go [to the FBI] because they would have always had the advanced technology and expertise."

Coffindaffer went on to say that the reason the DNA found at Guthrie's home was sent to a lab in Florida "was based on them having the profiles established." And while she understands that logic to an extent, she says that "knowing that [the FBI] had that technology, that should really have the Guthrie family and anybody who cares about justice for Nancy Guthrie upset."

Coffindaffer said it could take months for the latest rounds of DNA testing to be completed.

Shortly after ABC News reported that the DNA-identified specifically as hair by Fox News Digital's Michael Ruiz-the Pima County Sheriff's Department released a statement, its first in nearly a month, clarifying that the department has worked in tandem with the FBI and that "DNA analysis remains ongoing."
