Nancy Guthrie Case: Former FBI Agent Explains Why Suspect’s Car Hasn’t Been Identified

As the investigation into the disappearance of 84-year-old Nancy Guthrie closes in on its seventh week, both the FBI and the Pima County Sheriff’s Department appear to have made no breakthrough. 

Although there has been little progress in identifying the suspect in the case or locating Nancy after she was taken from her home in Tucson, Arizona, it isn’t for lack of trying. Now, a former FBI agent has explained some of the difficulties that law enforcement are encountering in the investigation. Posting on social media, Jennifer Coffindaffer specifically discussed the complexity of tracking down the car used by the suspect to carry out the crime. 


Retired FBI Agent Says ‘Desolate’ Route is Likely Reason Why No Witness Saw the Suspect’s Car

While discussing the case in a series of posts on X, Coffindaffer referenced an image of a map supposedly shared by Annie Gruthie with neighbors in the area. The hope was that somebody may have seen an unusual vehicle on that route that could lead to the suspect’s car being identified.

Coffindaffer suggested that the lack of street lighting and the remote nature of the area may be playing a major role in the lack of eyewitnesses. 

“I am all over this map,” Coffindaffer said. “JLR says Annie Guthrie had a group chat with neighbors and sent this map out to them at the beginning of the investigation hoping they may have seen something or may have video. Makes sense. Annie grew up there and still lived only 4 miles away.”

She continued, “Annie was desperate for answers. This is very usual with family members. Most importantly, this route is so desolate. Few lights. Few houses that aren’t offset. No traffic lights. The perfect path to get out of that neighborhood unseen if your car lights were off, especially. This could explain why no car has been identified yet.”


Guthrie Family Have Passed Polygraph Tests

In an appearance on “The Megyn Kelly Show” this week, former police officer and SWAT team leader Chad Ayers revealed the Guthrie family have passed lie detector tests, effectively ruling them out of the investigation. 

Ayers said, “I can also report that it has been confirmed this morning—and I’m sure we all assume this—that every family member passed polygraphs with flying colors.”

Host Megyn Kelly then replied, “That information is huge. So then that means—I don’t know, some people don’t believe in the polygraphs, I do—but if that’s true, then we can move on from the brother-in-law and the sister.”

“And it kind of sheds a little more light on the sheriff’s statement to NBC that he’s had a theory about this case from the beginning, and nothing has moved him off his theory. And that he does believe he knows the motivation for the crime,” she added.

This remark refers to theories online that Tommaso Cionio, the brother-in-law of Savannah Guthrie and the partner of Annie Guthrie, was a suspect in the case. The theory has previously been debunked by the Pima County Sheriff’s Department.
