Justizvollzugsanstalt München
Strupp went to Augsburg, hoping it would be a safer place for him to live than Duisburg, but was swept up by the Gestapo in the wave of arrests after the July 20 plot to kill Hitler. The 1944 arrest carried an increased chance of a trial before the Third Reich's People's Court. Strupp was liberated from Stadelheim Prison by American troops on May 1, 1945.
