I think I may have found the abandoned building being searched. Will include the map. If you watch the clearer daytime video, it looks very much like the map building. Behind a fence, another building near it, same number "windows". The video clearly shows a lot of the graffiti, too.
The building appears to be just off Vreeland on Peters, almost directly across Deer Creek Rd.
video with clear view of building is just below the main video, second one.
