There was this guy who was discharged from the military for being nucking futs and he was pissed that Pantera split up, so he decided that Vinnie Paul and his brother Dime where the cause of the split. He decided that he had to kill them, so he went to a venue in Ohio where their new band, Damage Plan, was playing and tried to kill them. The asshole managed to kill Dime and a couple of Roadies, if I remember correctly, before a badass cop nailed him point blank with a shotgun and stopped his attack. Vinnie was saved by a roadie that tackled him off his drum kit, but he still had to watch his brother and best friend get gunned down by that flaming asshat. https://www.rollingstone.com/music/news/behind-the-murder-of-dimebag-darrell-20041230 This was the first article I found.
