TUCSON, Ariz. — In the ongoing search for Nancy Guthrie, newly released footage from the FBI offers crucial insights that could potentially lead to identifying a masked individual captured in the video. Renowned body language expert Susan Constantine has analyzed the footage, uncovering significant physical and behavioral indicators within the images.

Speaking to Fox News Digital, Constantine highlighted several notable details from the footage that immediately captured her attention. Despite the subject being masked, Constantine noticed a puffy jawline, suggesting the possibility of beard growth beneath the mask. Additionally, the individual’s head shape and absence of visible hair suggest they may be bald.

Another point of interest is the subject’s backpack, which Constantine described as appearing full. She emphasized this as an important factor when evaluating the individual’s level of preparation.

The FBI released images that depict an armed person seemingly tampering with a camera at Nancy Guthrie’s front door on the morning she vanished in Tucson, Arizona, on February 1, 2026. This footage presents a pivotal moment in understanding the circumstances surrounding Guthrie’s disappearance.

From a behavioral standpoint, Constantine remarked that the solo appearance of the individual in the footage does not align with the typical dynamics of a botched robbery, which usually involves multiple people with assigned roles. The FBI has yet to disclose any identified motive or the subject’s potential involvement, leaving these details shrouded in mystery as the investigation continues.

From a behavioral perspective, Constantine said the circumstances shown in the footage do not appear consistent with a robbery gone bad, noting that robberies often involve two or three people with defined roles. The FBI images released so far show one individual, and she emphasized that investigators have not publicly identified a motive or confirmed the subject’s role.

Despite the subject wearing a mask, Constantine said the footage still reveals identifiable physical traits.

“Even with the mask on, we can still see his eyes, his body structure, his proportions and his gait,” Constantine said. “All of those things are identifiable.”

She described the subject as appearing physically fit and athletically built, with most likely brown eyes, tightly trimmed facial hair and what she described as an olive-toned complexion.

The new images and videos were revealed Tuesday by FBI Director Kash Patel as the search for Guthrie entered its tenth day.

Patel said investigators recovered the footage using residual data from backend systems after recording devices at Guthrie’s home were removed or rendered inaccessible.

“Over the last eight days, the FBI and Pima County Sheriff’s Department have been working closely with our private sector partners to recover any images or video footage from Nancy Guthrie’s home that may have been lost, corrupted, or inaccessible,” Patel wrote. “The video was recovered from residual data located in backend systems.”

According to Patel, the newly uncovered images show an armed individual appearing to tamper with a camera at Guthrie’s front door on the morning of her disappearance.

Constantine said the moment captured on video would have been frightening.

“Can you imagine an 84-year-old woman having someone like that standing over her, wearing a mask?” she said.

She stressed that releasing the footage publicly could be critical to generating new leads.

“Someone is going to notice something,” Constantine said. “The clothing, the gloves, the backpack — those are linkable details.”

The FBI is urging anyone with information related to Nancy Guthrie’s disappearance to contact 1-800-CALL-FBI.
