In front of room 111 Steinhäuser met the teacher Rainer Heise. The perpetrator had already removed his face mask, so the teacher could recognize him. The teacher was aware of the extent of the events of the last few minutes. He was also aware that he had the gunman in front of him. He said to Steinhäuser, "You can shoot me now," and looked him in the eyes. However, Steinhäuser lowered his weapon and said: "Mr Heise, that's enough for today." According to Heise, he asked Steinhäuser to come for a conversation in the next room (room 111, material room art), Steinhäuser followed the request, went to the open door and was then pushed into the room by Heise to be locked up in it. Shortly thereafter, Steinhäuser shot himself, the shot was heard by a police officer and his body was found by police a few hours later.
