Carlos Ray Swist, 43, was shot and killed on March 1, 2016, in Austin, Texas, while driving a florist company van. The shooting followed an altercation at a convenience store over a $5 bill that had fallen on the floor; store surveillance reportedly showed Swist was not the aggressor. A projectile recovered from Swist’s head was later matched to an unfired .357-caliber round found in Dixon’s car.

Dixon was arrested a few days after the killing. Family members described Swist as a man trying to turn his life around and deeply devoted to his 4-year-old daughter.
