I don't know the area but it appears to have a lot of bars, etc in the general vicinity. I live in Ontario and there's been the same kind of clubs close to the water with individuals drowning nearby, usually through misadventure. If there werent an altercation at the BH previous to his disappearance,,, and the two known people that were with him that nite would have shared his flier,, I would find this plausible . Im not saying either of the two known people are guilty ,,, but between the girl having his phone for so long and an altercation ,,, neither of these sit well with me
I don't know what happened to Caleb but drunk men who've had lots of beers are known to urinate outside so it's possible that a lot of them think peeing into a river or a lake is better than peeing against a wall. If you lose your balance against a wall you might get bruised, but if you fall into water there's a good possibility you will drown because you're standing on a pier not a beach.
