The shoe was found right out side the door Shane opened and got out of....He got out drivers door and the Westwego cop was the person who broke the window...
When you all saw the shoe, was it covered in mud, as if he had stepped off into it and stepped out of it because the suction had taken it from him? Did anyone see any signs of bare feet? I only ask because a barefoot would never have been mistaken for a shoe print.
I hate to even say this, because I know you are his uncle, but I am being practical in my thinking, and I truly believe all of you need this now...If the shoe had no visible signs of being stuck in mud, that shoe was knocked off by some sort of impact. It could have been the impact of the accident, itself, which would have been evident because of bare foot tracks, in my opinion, or it could have been left because of a secondary impact after the accident, let's say a vehicle/pedestrian post-automobile accident.
I don't know your nephew, but I can promise you this much, if he were mine, I would be doing exactly what you are doing.
What I do know about your nephew leads me to believe he was in trouble with the law, and he knew it. He had no reason to run. His freaking BROTHER was on his way to do whatever he needed to do to help him. You don't run when your brother is one his way! You just...don't.
It is hard to believe an accident after the accident happened in that amount of time and LE was able to cover it up without Brett even suspecting.
It is harder to believe Shane walked and was just never seen again.
If we apply common sense, there is a cover up somewhere, and it happened within just a couple of minutes. If we find those few minutes, we find Shane.
