ORCHARD PARK, NY - Police say they have located a 26-year old man who went missing near Ralph Wilson Stadium after Thursday night's game, but they have not released his condition or said where he was found.
Officials on the scene have described it to 2 On Your Side's Heather Ly as a "recovery mission."
Orchard Park police will only say that he has been found and that the investigation is ongoing. They're holding a news conference this morning to give more information.
Investigators "pinged" the man's cell phone early this morning telling them that the phone's location is just north of Shadow Lane off of Big Tree Road.
Foul play does not appear to be a factor at this time."
