Ahhh this story is so unfortunate. Seems that he was kind of drunk and then supposely some North Africans robbed him and he went after them or with them to the river edge. Probably lack of language and communication going on. Then he was left there arguing or talking to the Homeless people that live down there. They were probably trying to tell him to leave. He didn't want to or he just did not understand. Then one of them go mad and decided to push him off the river. But there were rapids there and rocks further down.
