Crooks was fatally shot by Secret Service snipers and authorities later recovered an AR-style rifle at the scene. Crooks hailed from Bethel Park, located 40 miles south of the rally in Butler. The reasons for Crooks firing at the former president nominee are still unknown. Two Secret Service snipers can be seen scanning the area where the shots ultimately came from before Crooks opened fire. They immediately responded with shots of their own.
