1:20 PM PT -- The Oskaloosa Co. Sheriff just released a statement saying they searched the area where the image was taken extensively and didn't find anything, or anyone, of interest. Cops searched using a drone, and checked nearby farmlands.
In a statement, cops said, "There are no known possible past or current connections between Laundrie and anyone in this area at this time to follow up on."
The hunt for Gabby Petito's fiance, Brian Laundrie -- who's believed to be the last person to see her alive -- may have broken wide open ... because someone thinks they spotted him about 500 miles from his Florida home.
Sam Bass says a man fitting Brian's description was seen on his trail camera set up in the wilderness in Baker, FL early Monday morning ... and he's alerted the authorities.
Bass' deer camera footage shows a man with a backpack trekking through the woods, and he certainly resembles Laundrie ... who was reported missing by his family after being named a person of interest in the disappearance of Gabby.
Folks were quick to point out Baker is about 450-500 miles away from Laundrie's home in North Port -- which would be quite a journey on foot over 4 days -- but the Okaloosa County Sheriff’s Office has confirmed it's actively looking into the footage ... but there's no confirmation it's Brian yet.
People have also pointed out that the man's backpack is similar to Laundrie's, and his parents told authorities he left with it on a hike Friday and never came back.
As we've reported ... the story of Gabby and Brian -- who were on a cross-country trip this summer and documenting it on social media -- garnered national attention when he returned to his Florida home without her on Sept. 1.

Gabby was reported missing 10 days later by her family, who claim Brian was not cooperative at all in trying to locate her, and the feds believe they found her body at a national park Sunday in Wyoming ... a place she was believed to have visited with her fiance.
There was also a domestic dispute between the couple in mid-August in Utah, but the authorities released them with no charges or arrests. A 911 caller from that incident said they had observed Brian physically attacking Gabby ... she went missing sometime after that.
