Out of morbid curiosity I googled his name to see if his case came up, because 3 years is a long time for an assault charge:

He didn't just attack someone. He and his three brothers broke into the guy's house and beat him with the intent to kill him. He was only acquitted of the "intent to murder" piece as part of an appeal.
