ROCKFORD, Ill. — A jury in Rockford has found a Chicago man not guilty of first-degree murder in a case involving a gun battle in a restaurant parking lot.

Forty-nine-year-old Charles Knight was acquitted Thursday in the April 2005 death of 21-year-old Joshua Irwin.

Prosecutors had accused Knight of robbing Irwin outside a Rockford Pizza Hut and shooting the Rockford man in the head. Defense attorneys contended there was no robbery and that Irwin pulled out his own gun and fired at Knight, who shot back in self-defense.
