ALIQUIPPA, Pa. — You can still see bullet holes in the screen door of a home in Linmar Terrace after a shooting around 12:30 a.m. Sunday. Four people were shot and taken to the hospital. Three of them, investigators say, were innocent bystanders. “They were just having a party, celebrating the Fourth of July, America’s 250,” Beaver County District Attorney Nate Bible said. “I think he just thought, hey, maybe I can blend in with this group and just kind of get away,” Bible said.
