My guess would be he bumped a guy by accident in the bar (or more correctly, a guy bumped him) and then got in his face (NFL CBs would have no fear and not back down to anyone). He was with a woman which made the hypothetical confrontation more intense for his honor. The guy followed him out to the car and shot him.
same shooter of julius hodge perhaps?
To be honest, never saw one of them,
Fox News just said another player may have been in the car with him.
