New video’s surfaced in the search for Nancy Guthrie‘s kidnappers … a man in Tucson with a goatee, who creepily approached a doorbell camera one week before Nancy was taken, and TMZ has learned cops are giving it a hard look.

The video was originally posted January 23 on Ring’s Neighbors app, and it shows the guy intentionally backing up to the front door of a home about 6.5 miles from where Savannah Guthrie‘s mother lives.

The man clearly didn’t want to be seen, but the camera still got a good shot of him as he rang the doorbell around 5 AM. The homeowner who posted the vid says the would-be intruder fled when their dogs started barking.

The dark-haired individual does have facial hair that seems similar to the person seen in the FBI-released images captured by Nancy’s doorbell camera.

Although that person was wearing a knitted ski mask, you can still see a goatee or beard underneath the material.

As we reported, the cops are asking residents within a 2-mile radius of Nancy’s home to check security cameras for anything suspicious during the entire month of January … as you know, Nancy was reported missing on February 1. This particular video is making the rounds on social media, so citizens are answering the call.
