Commandant Franz Ziereis

After Commandant Ziereis fled from the camp, he was hunted down by the American liberators and eventually captured in late May 1945. The dates and location of his capture and death vary according to who is telling the story. Ziereis was shot three times by American soldiers, allegedly while trying to escape. He was brought back to the hospital at the Gusen camp and interrogated by an Austrian anti-Fascist political prisoner named Hans Marsalek, who later wrote Ziereis's deathbed confession in which Ziereis said that, on the order of SS-Hauptsturmführer Dr. Eduard Krebsbach, a gas chamber had been built in the form of a bathroom and that Mauthausen inmates were gassed in this room.
