A Casper man who prosecutors say stabbed another person in a drunken scuffle changed his not guilty plea in district court Friday.

33-year-old Ira Goff pleaded guilty to one count of aggravated assault in a plea deal with prosecutors. Prosecutors then agreed to drop an additional aggravated assault charge along with assault and battery and interfering with a peace officer charges.

Investigators say an intoxicated Goff stabbed a man outside a Casper bar in a fight with two other men back in May. Goff then tried to flee the scene by climbing over a fence when police arrived.

Goff faces 30 to 54 months in the Wyoming State Penitentiary. Sentencing will be set for a later date.
