the course of the investigation, it was found that none of the victims died because of locked evacuation doors. Post-mortems carried out on victims have shown that none of them died of exposure; all died because of injuries sustained because of the collapse of the roof. Location of MTK There has been some confusion over whether MTK is located in Katowice or Chorzów. The registered and street addresses of the company are in Katowice, and the entrance to the grounds is from a street that belongs administratively to Katowice. However, the company's grounds—and thus the site of the catastrophe—lie within Chorzów's administrative boundaries.
