Investigators say Rittacco was at the restaurant on Morgantown Road to drop someone off at work. As he was leaving, a black Acura sedan pulled up behind him and Rittacco pulled back into a parking spot.

Then, police say the victim, Robert Lukehart, got out of the car and ran up to Rittacco’s window. According to court paperwork, Rittacco told police he shot Robert Lukehart because “he approached his vehicle in an aggressive manner and felt his life was threatened.”

Rittacco is accused of firing approximately three rounds from a pistol, striking the victim before fleeing the scene.
