Former FBI agent Jennifer Coffindaffer said surveillance video from Nancy Guthrie’s Tucson, Arizona, home may contain overlooked clues in the 84-year-old’s disappearance.
Guthrie, the mother of TV host Savannah Guthrie, has been missing for four months after investigators said someone abducted her from her home.
The video shows a masked figure near Guthrie’s house before the disappearance. Investigators have referred to the person in the footage as the “Porch Guy.”
Coffindaffer said small details in the clip deserve closer review. She pointed to what appeared to be a watch on the person’s wrist and the way the figure moved near plants around the camera.

She said those movements could help investigators assess which hand the person used more often. She also said the figure may have looked toward someone else while holding a small device.
However, Morgan Wright, founder of the National Centre for Open and Unsolved Cases, told Fox News Digital that publicly known evidence points to one kidnapper. He cited the single person visible on video and the absence of a reward claim.

Wright said the FBI’s next breakthrough may come from video forensics, signal analysis or blockchain tracing. He said investigators could use those tools to identify a suspect, a vehicle or the source of ransom-related activity.
The FBI and Google previously recovered Nest doorbell footage after the camera device went missing. Investigators have also reviewed video, messages, DNA evidence and Bluetooth signals linked to Guthrie’s pacemaker.
The Guthrie family has urged anyone with information to call 1-800-CALL-FBI. A combined reward of more than $1.2 million remains available for information that breaks the case.
