You got it mostly right. However, the incident started the night before the actual shooting at same bar. The shooter came back on the next night and shot the victim (term used loosely as he was a local gang banger). This was a case of murder and how the shooter was found innocent, I will never know.

Wow. I had no idea the guy ended up not getting found guilty. I was not on the jury so I guess my opinion is not relevant. But wow.
