The Cologne school massacre was a mass murder that occurred at the Catholic elementary school (German: katholische Volksschule) located in the suburb of Volkhoven in Cologne, North Rhine-Westphalia, West Germany, on 11 June 1964. The perpetrator, Walter Seifert, also known as "Der Feuerteufel von Volkhoven" ("Firedevil of Volkhoven"), attacked the people at the school with a home-made flamethrower and a spear, killing eight pupils and two teachers, and wounding twenty-two others. When police arrived at the scene, Seifert fled from the school compound and poisoned himself. He was taken to a hospital, where he died the same evening.
