I wonder why Betts was refused admission to the bar? Had he caused trouble on a previous occasion, or earlier that night? Was he intoxicated? Or was there just something “off” about him? Or maybe it had nothing to do with him personally, e.g., the bar was at capacity, or it was near closing time.
His 22 year old sister was shot there as well. Beef with her being there? Was it the guy she was dating? No clue.
