The Erfurt school massacre was a mass shooting that occurred on 26 April 2002 at the Gutenberg-Gymnasium, a secondary school in Erfurt, Thuringia, Germany. 19-year-old expelled student Robert Steinhäuser shot and killed 16 people, including a police officer, before killing himself. One person was also wounded by a bullet fragment. According to students, he ignored them and aimed only for the teachers and administrators, although two students were unintentionally killed by shots fired through a locked door.
