Seifert then fled the school compound and swallowed E605, a poisonous insecticide, to commit suicide, but as the substance was diluted he did not die immediately. Chased by 20 to 30 people he ran towards a railway embankment where he tried to fend off his pursuers with his spear. When police arrived at the scene at 09:38 he tried to stab one of the officers, but was eventually immobilised with a shot in his leg. He was arrested and taken to the University Hospital in Lindenthal where he was questioned several times, before he died at 20:35.
