Two accidents in a month?

Awhile back there was a car crash nearby and from what I heard no one is really sure why it happened. The car was going too fast and at least one person died. There was just an accident on the on the same street but a bit further down. I'm not sure of all the details but it involved a car crushing a man. I just feel so bad and want to do something but at this point there's not much I can do. Maybe I can once more information comes out. It feel very surreal.
