One killed, 7 wounded in LoDo shooting

Guess there was a shooting in Lodo last Sunday morning, after the bars closed at 2. Sounds like a couple of groups of guys got into some drunken dissing match in a bar, one of the groups got kicked out then waited for the other group came out when the place closed. And one of the gang pulled out a gun and started shooting. Nice. Drunken people talking shit and one of them happens to have a gun. Wonder if he bought it for self defense? Actually, I wonder how it went down exactly? What exactly precipitated the shooting? Where there punches thrown prior to this?
