One thing we can be fairly sure of:
The 4:00 AM sighting was not Jeremy. He was calling 911 from the home and he is not 5'7" to 5'9" either. The first sighting (12:00 AM,) in some news report, and I can't find the link even though I have tried, reported that the man was "African American." If that report is true then it wasn't Jeremy or DB's brother. Also, LE said that lead had been followed up on and didn't go anywhere.
The only other people, that we have heard about, to come onto LE radar are "Jersey" and the neighborhood teen. The teen can probably be ruled out because he wasn't in his 30's. (We have been told by our confirmed Local that the teen was a male.) Still not sure if Jersey can be ruled out for either sighting as we do not know his race.
Jersey is white and LE has already said he had nothing to do with any of it. By the way I have not heard anything from these witnesses to indicate what was the race of the man they claim to have seen.
