Nancy Guthrie Update: Former FBI Agent Says DNA Sent to FBI Could Be a ‘Very Good Sign'

There is a renewed interest in the Nancy Guthrie case after ABC News reported that the FBI has received DNA from Guthrie's Arizona home that was collected back in February. That DNA, reportedly hair, was initially sent to a lab in Florida for testing by the Pima County Sheriff's Department early on in the case. However, the lab has released the sample and the FBI will use advanced technology to try to figure out who it belongs to.

Former FBI agent Steve Mooresat down with Brian Entin to talk about the sample during the April 20 episode of Brian Entin Investigates.

"It could be a good sign," Moore said of the FBI receiving the DNA. "I mean, it could be a very good sign. ... I would have just bundled up the entire bed sheet thing and tied it at the top so everything that was in the bed would go to the lab."

"You cannot walk across the room without leaving some type of evidence," Moore continued. "I suspect [Nancy] was helped out of bed, simply because of her age. And, if you do that and you lean over the bed... I mean, why do people wear hair nets in restaurants? Because we know hair falls in food. Hair would have fallen in that bed."

Moore thinks there's likely a great deal of evidence in Guthrie's sheets and blankets, and he said he's "encouraged" by the news that there's a hair in play.

Moore isn't the only former FBI agent who seems optimistic about the DNA transfer. Parade previously reached out to Greg Rogers who said that the FBI's lab is "the best in the country." Rogers went on to say that the DNA results could come back in "a matter of days."

Guthrie, 84, has been missing since Sunday, Feb. 1. Anyone with information about her whereabouts or who might be responsible for her disappearance has been asked to call the FBI (1-800-CALL-FBI).
