I am trying to say this video is a reenaction on what happened. The story is true but this video is just a demo on what happened. Just pause at 0:32
and look at the left of the scene and see a girl just looking at the boy. Next pause at 0:48
and see the same girl swimming behind him. If this was the actual event dont you think that girl would do something instead of looking at him and then just swimming behind him?
