The Cologne school massacre was a tragic event that occurred on June 11, 1964. Walter Seifert, also known as "Der Feuerteufel von Volkhoven", entered the Catholic elementary school located at Volkhovener Weg 209–211 in Cologne, Germany, brandishing a flamethrower, lance and mace attacking children and teachers. The incident resulted in the deaths of eight children and two adults, and many others were injured. To this day Seifert's motive remains unclear.
