A Casper man already serving time behind bars, will stay there for a little bit longer after he admitted that he tried to re-enter a bar with a gun, because witnesses say he wanted to kill someone.

John Knox was sentenced to four-to-six years in prison, after he pleaded guilty to one count of aggravated assault.

Investigators with the Natrona County Sheriff's Office say in middle January 2016, 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, which he was convicted by a jury, when this incident took place.

His new sentence of four-to-six years will be served concurrently, or at the same time with the other sentence.
