After the end of World War II he was convicted of war crimes and sentenced to death by hanging. The sentence was later commuted to a short prison sentence, and after release went to live in Travès, in France. He was murdered in a fire bomb attack on his house on July 14 1976. The murderers were never caught - they are most widely suspected to be French Communists, but other theories have suggested former French Resistance fighters, or even a Jewish revenge squad carried out the attack.
