Well he wasn't living in Brazil. He was living in Argentina, protected by the German community there. They didn't advertise that, although people like Juan Peron knew they were there. According to the declassified CIA documents, he visited the German community in Columbia in 1955, when he assumed the 10 year statute of limitations for war crimes had expired, and he was treated as hero. He returned to Argentina after that. He may have visited Brazil, but he likely remained in Argentina until his death between 1962 and 1965.
