Amish children carrying lunch pails arrived at a new one-room schoolhouse in Lancaster County, Pa., this morning, marking a fresh beginning for students who survived the shooting that killed five classmates last fall. The New Hope Amish School sits a few hundred yards from the spot where the killings took place. Built by the entire community, the school is protected by more sophisticated locks on its doors and is reachable only by a private drive. It replaces the West Nickel Mines Amish School, which was torn down Oct. 12. Ten days earlier, milk truck driver Charles Carl Roberts IV shot 10 girls inside the school and then committed suicide as police closed in.
