Even if it was a robbery, where’s the body and where’s the wallet?
The bar said they handed the kid back his credit card, so it was probably in his shirt or pants pocket. The video shows he was falling down drunk he was so out of it. So it may have fallen out of his pocket.
They will probably find his body down river in a few days.....................
If you are falling down drunk, it definitely is possible to fall into a river. That’s not inconceivable at all. However, I would say it’s more likely that he was helped into the river. Speaking about probability, a falling down drunk person will definitely attract attention to themselves. Also, evil people are opportunists. They prey on the weak and vulnerable, and do things when they think no one is looking or when they think they can get away with it.
