So has any details come out about what exactly he was doing? Was he seated and jumped up and leaned too far? Was he running down the stairs?
From what I saw in the only article I read, it sounded like he got up, like got up from his seat, and went over. And I'm just wondering how that is possible. I can see him going over the rail if he was running down the stairs. But even then, you really don't see that in the top level going down ever. And considering the MLB mandated that the rails be raised after that one fan died, I think it might even have been at Atlanta. A foul ball, and reaching over to grab it isn't part of the equation.
And remember, this happened in the first inning. I guess if he was tailgating all day, he could be that drunk to fall over.
