Savannah being missing didn't come out in the media the next day, if you were not aware she was buried or dead you may not know she was missing until you heard it from the media or someone else, like Law Enforcement. I think the story she was missing came out on the 8th of Jan. Maybe that was the date they stopped David when he was driving but I don't think her being missing came out on the 5th., I will check this out. If the story is true there is a video of sex acts I would assume one of the two guys, not David, had the video on his phone and chose to show it off at work before he knew she was missing. Or another theory would be, the man who showed this video at work thought it was a way to show she was alive and giving oral sex to all as a way to cover up his or their guilt in forcing her to have sex and possibly trying to cover up guilt in her dying too. It wasn't the brightest thing to do but no telling why it was done. It could show Law enforcement things that will help with evidence toward a conviction in charges they may file.
