This's the story on it from what I've heard, my friend told me about it... A man jumped up on stage and shot him five times and shot and killed two other people as well, and some cops shot the man who was doing all the shooting, so there was actually four deaths at that DamagePlan concert. It really upsets me that people would do that, because I play guitar and I have intentions to become famous...
But that's not the point, I love DamagePlan and Pantera, both are awesome bands, I don't see why he would shoot him if he really loved Pantera that much, cause now there's no Pantera and never will be again, their guitarist is dead... R.I.P. and long live metal!!!!
