Man sorry you witnessed that. It's never to see someone die. Even if you don't know the person it stick with you. Hope you get to feeling better!
What makes it worse is he has a wife and kids. I just cant explain how much it hurts me to know that this happened. Yeah you hear about it on the news and stuff but its just so hard to see it then imagining what their family is going through. And it happened just like that. No warning, no anything. Just here one minute and gone the next.
