On March 31, 2012, prosecutors say Waldron was in a car driven by his daughter when three men walked by and one briefly sat on the hood.

Shortly after, the men say Waldron came up behind them and beat one of them over the head with a gun, causing serious injuries. Waldron’s also accused of pointing the gun at the other two men.
