In South Carolina, nine people were injured early Sunday as gunshots rang out at a nightclub in the town of Furman. It was the second mass shooting in South Carolina over the weekend, following a Saturday shootout at a shopping mall in Columbia that left 14 people injured. Meanwhile, police in Pittsburgh, Pennsylvania, are searching for suspects who opened fire on a party at an Airbnb property early Sunday, killing two 17-year-old boys and injuring at least a dozen other people. Pittsburgh officials say as many as 200 people were attending the party — many of them underage — when multiple assailants fired at least 90 rounds from handguns and at least one rifle. Among the injured were people who leapt from high windows to escape the violence.
