premise: WINNENDEN, Germany ―A teenage gunman killed 15 people, most of them female, on Wednesday in a rampage that began at a school near Stuttgart in southern Germany and ended in a nearby town, where he then killed himself after the police wounded him. The attack left Germany, which tightened tough gun controls after a similar attack at a school seven years ago, struggling to understand the carnage that had again befallen it, a country with relatively little violent crime. In 2002, a gunman killed 16 people before killing himself at a school in Erfurt, in eastern Germany.
hypothesis: In 2002 near Stuttgart a boy shot 16 people.
