wow, I didn't realize until I sat here and thought about it. 4 people that i knew.
In the 70's my uncle was shot and killed in a bar fight. He was a big man and had a rep of not losing fights. I got the story from the uncle who was there. He (the younger uncle) was with him in the bar when it happened. The older uncle pushed the younger one under the pool table when he realized what was going to happen. I think he saw the killer coming in with a gun. It's been a long time, so that's about all that I know about it, I'm not sure if the killer was caught. I think he was, otherwise other uncles and/or my dad would have either also been killed or would have killed him.
