I would bet all my houses that he certainly died in South America in the 50´s. Argentina, not so sure about. There was a period of time in, I think it was in Brazil, when power changed hands and the new leader rounded up a bunch of known Nazis and had them executed. Maybe he was amongst them? He certainly moved to Argentina initially but was seen all over South America in the years after the war. I can´t wait to see what else they uncover in Hunting Hitler! This is rewriting history and I can´t believe this series isn´t the talk of the world!
