A Casper man is accused of trying to re-enter a bar with a gun, because witnesses say he wanted to kill someone.

John Knox has pleaded not guilty to one count of attempted second degree murder, one count of aggravated assault, and one count of possession of a deadly weapon with unlawful intent.

Investigators with the Natrona County Sheriff's Office say in middle January, Knox was at Racks Gentlemen's Club, when he got into an argument and fight with another patron, and ended up being kicked out of the bar by bouncers.

One bouncer heard Knox say “‘Get him out here, I’m going to get my banger,'” and then saw Knox go to a vehicle, rummage around the front and back passenger seats and found a pistol, racked the slide to put a round in the chamber, and tried to get back into the bar.

One witness heard Knox say he wanted to kill someone.

Prosecutors say knox was out on bond on an unrelated assault case, when this incident took place.

Knox is awaiting trial on $50,000 bond, and could face between 20 years to life in prison on the attempted second degree murder charge, if convicted.
