There is a new development in the Nancy Guthrie case.

According to Fox News, the man seen in the chilling porch doorbell footage approached Nancy Guthrie’s front door the night before her abduction.

The photos released by the FBI of the suspect on Nancy Guthrie’s porch were taken on two different days. In the first photo, the suspect is not wearing a backpack.

84-year-old Nancy Guthrie was abducted from her Pima County, Arizona, home on February 1.

Police still have not identified a suspect.

One of Nancy Guthrie’s Nest doorbell camera images released by the FBI was taken on a different date than the others, a source with knowledge of the investigation confirmed to Fox News Digital Monday.

The new details indicate the masked suspect scouted the home in advance of the 84-year-old Guthrie’s suspected abduction on Feb. 1.

The source declined to specify what day the earlier image was taken, citing the active investigation.

Pima County Sheriff Chris Nanos tells Fox News that the information did not come from him.

Authorities have alternately asked for neighbors to check their home security systems for the entire month of January, the night of Jan. 11, and the hours surrounding Guthrie’s disappearance, between Jan. 31 and Feb. 1.
