Federal agents returned to the Arizona residence of Nancy Guthrie on Wednesday, spending several hours combing through the property before determining whether her family would be permitted to move back in, sources told The NY Post.

The latest search indicates that the probe into the 84-year-old’s disappearance has stalled, as she has now been missing for 25 days and investigators have not publicly identified any suspects in the perplexing case.

Agents arrived at Guthrie’s Tucson home early Wednesday and remained at the upscale property for more than two hours as part of what sources described as a final review of the scene.

According to those familiar with the investigation, authorities were believed to be checking for any remaining evidence that may have been missed during earlier searches before potentially clearing the house for the Guthrie family’s return.

Guthrie — the mother of “Today” show host Savannah Guthrie — was first reported missing on Feb. 1 after she failed to attend church services that morning.

Video obtained from her doorbell camera showed a masked individual — or possibly two different individuals, as some observers have suggested — lingering outside her front door on the night investigators suspect she was abducted.

The footage shows the person carrying a black Ozark Trail Hiker backpack and attempting to obscure the camera’s view with tree branches.

Later that morning, on Feb. 1, Guthrie was officially reported missing.

Residents of the Catalina Hills neighborhood subsequently told authorities that they had noticed a suspicious young man spending time on the street near Guthrie’s home in the weeks before she vanished.
