Well the police were looking at his records over the years and he was perfectly fine but in 2010 or 2011 he went insane when the Dark Knight came out. He said he was planning this for a long time. He died his hair red, wore a gas mask and a bullet proof vest. The actually smart thing he did was he started shooting at a shooting scene in the movie because people just thought it was just the movie. He gave him self up afterwards. He said that his car was filled with explosives. His house was booby-trapped with chemicals attached to wires and such. In his apartment a lot of people who lived in the same building as him didn't know he actually lived there. He was trying to act like the joker with red hair.. lol! Hope that helped sorry if its long, thats all i saw on the news..
