a mentally devious person with no will to recover. Seifert again contested the report and wrote a letter titled "Sozialpolitik - Sozialärzte — Sozialmord" (social politics — social doctors — social murder), whereupon he was examined by a medical specialist who noted Seifert's quirky behaviour, his scattered train of thought and his constant smile in inappropriate situations.

His flamethrower was made from an insecticide sprayer with a wire netting attached to the nozzle, and filled with a mixture of old motor oil and paint thinner. Massacre On 11 June 1964, shortly after 09:00, Seifert approached the schoolyard of the Catholic elementary school located at Volkhovener Weg 209–211, armed with a self-made flamethrower, a spear and a mace.
