That is terrible. You just go to watch a game and you fall off a walkway. I wonder what area he fell from? Last time I went to a game (playoffs vs Packers last year) it seemed like there weren't many places you could fall from unless you were really going out of your way.
Sad to hear news and my best wishes to the family and friends, but alcohol and weed is a big problem. There needs to be a strong crack down with people who smoke shit and drink too much before or during or after the game.
