took form in the Sobibor revolt. Wagner was not present at the camp on the day of the Sobibor revolt on 14 October 1943, having taken a holiday with his then wife Karin to celebrate the birth of a daughter, Marion. The inmates knew of Wagner's absence and believed that it would improve their chances of success. Wagner was considered the strictest in terms of prisoner supervision at the camp. After the successful revolt, Wagner was ordered to aid in closing the camp. He helped to dismantle and remove evidence of the camp by ruthlessly commanding the Jewish prisoners who performed this task. For instance, after the Arbeitsjuden "worker Jews" had been transported from Treblinka and had successfully torn down the Sobibor barracks, Wagner killed them. Heinrich Himmler considered Wagner to be "one of the most deserving men of Operation Reinhard" (). After Sobibor, Wagner was transferred to Italy, where he participated in the deportation of Jews. After World War II Wagner was sentenced to death in absentia, but escaped with Franz Stangl to Brazil. Clergy at the Collegio Teutonico di Santa Maria dell'Anima in Rome assisted Wagner in his flight from justice to Syria. Wagner was admitted as a permanent resident on 12 April 1950 and on a Brazilian passport was issued in the name of "Günther Mendel", his new identity. He worked as a house-helper for a wealthy Brazilian family and then as a maker of concrete fence posts. He married a local woman who was a widow and raised her children. Wagner was arrested on 30 May 1978 after an investigation by Simon Wiesenthal. When Stangl had been put on trial in Germany, he testified that Wagner was living in Brazil, but the Brazilian police failed to locate him. When a journalist showed Wiesenthal a photograph of a group of German-Brazilians celebrating Hitler's eighty-ninth birthday, Wiesenthal falsely identified one of the men as Wagner, thinking that he could spook Wagner into fleeing and inadvertently revealing himself. However, Wagner instead surrendered himself to the Brazilian authorities, who then refused extradition requests from Israel, Austria, Yugoslavia, West Germany, and Poland. Wagner, in a 1979 BBC interview, showed no remorse for his activities in running the camp, remarking: In October 1980, Wagner was found dead with a knife in his chest in Atibaia. Wagner's attorney reported his death as a suicide though Szlomo Szmajzner implied to Jules Schelvis and Richard
