That incident happened in the early 90's in C. Springs in a bar called Jim & I's on the corner of Fillmore & Nevada ave. The Bartender (P.K. Kline) was killed, as well as some guy outside (Steve somebody). The gunman went back to his truck to reload and the police engaged him from the corner of the spagetti diner and eventually nailed him when he was reloading.
I remember the incident real well I lived about 1/2 mi from there and went up & looked at the holes in the corner of the spagetti house, and it was all over the news but I don't have any specific links to anything. The Bartender was well liked so if you google his name maybe the story will pop up. I am going from memory here, myself.
