PITTSBURGH (AP) _ A man was acquitted of killing a person and shooting another after a four-year dispute over his neighbor's loud music and ceaseless partying.

Dennis Norkiewicz, 47, who claimed the shooting was in self-defense, was found guilty Friday only of carrying his .357-caliber revolver without a license, punishable by up to nine months in jail. He was acquitted of homicide, aggravated assault and reckless endangerment.

``It's a terrible, terrible verdict,'' said Robert O'Malley, 45, who was wounded in the shooting. ``It's a shame to kill and walk away free.''

The O'Malleys moved next door to the house Norkiewicz shared with his mother in 1992. O'Malley said he and his wife drank at least a case of beer a day and would drink in their yard and play music almost every day.

Stopped from taking a nap, authorities said Norkiewicz took his gun and confronted O'Malley at the fence May 19, 1996. Prosecutor Kenneth Haber said Norkiewicz could have fired into the air or fled indoors when he saw O'Malley and his friend rush toward him. Instead he shot O'Malley in the stomach and killed Michael O'Connell, 24.

Defense attorney Jack Conflenti said Norkiewicz feared for his life.

``He brought his quietness, his thoughtfulness, his peacefulness to that neighborhood dispute and it ran out,'' Conflenti said.
