Escape from Sobibor, upon which the infamous Rutger Hauer TV-movie was based, consists of a 370+ pages long uninterrupted narrative based mainly on a number of survivor interviews (it has a part on the sources in the back) as well as on the well-known but hard-to-get book by Rueckerl on the 1960's NS trials. The most interesting part is the end, where Rashke (a non-Jew) talks to Sobibor "survivors" in Canada, the US, Israel and South America.
For example, Rashke together with Toivi Blatt visits Shlomo (Stanislaw) Szmajzner, a survivor upon whose testimony a large part of the first half of the book is based, in his home in Goias, Brazil.
After a while, their talk turns to the arrest of Gustav Franz Wagner, a former SS guard at Sobibor.
Wiesenthal knew Wagner had been hiding in Brazil since 1950 because Stangl had so testified during his trial in Duesseldorf. Wiesenthal asked the police to find Wagner - he, too, was living under his own name - but the police said they couldn't. Suspecting that Wagner was being protected, Wiesenthal decided to play a waiting game. If Wagner felt that no one was looking for him. maybe he would make a mistake. So over the next decade, the Nazi-hunter spoke constantly about Joseph Mengele, the infamous Auschwitz doctor, but never about Wagner.
(p. 313)
Comment: even if "protected" why live under your own name if you are guilty of the murder of 250 000 people. If, like Stangl, he was even registered at the Austrian consulate in Rio, it makes even less sense.

Above: Wagner had a passport issued to him in his own name in Rio in 1950.
Rashke then recounts how in 1978 pictures had been taken of Wagner and others at a "secret meeting at the Hotel Tyll" where he and others were celebrating the birthday of Adolf Hitler. The photos reached Wiesenthal. Wiesenthal then identified a man in the pictures who was not Wagner and publicized information on him.
(p.313-314)The Germans in Brazil eliminated [really? see below] the dark man with the big ears. But Wagner, fearing that Israeli agents were after him, called the police and offered to surrender on a Sao Paolo street corner. Germany, Israel and Poland had each requested Wagner's extradition.
Schlomo was watching the evening news when he saw Wagner's face on the screen. He nearly went crazy with anger, realizing that for almost thirty years he had been breathing the same air as Wagner. He jumped on the first plane for Sao Paolo, because if someone did not positively identify the Nazi as Sobibor's Gustav Wagner within a few days, the police would have to release him, and he could then run off to Paraguay or bury himself in some remote Brazilian village.
Schlomo found Wagner in the holding tank with several other prisoners.
"Hello, Gustl," he said, using Wagner's more intimate name.
"Who's that? Who said that?" Wagner seemed confused.
"It's the little Jewish goldsmith from Sobibor."
"yes, yes, I know you. I saved you," Wagner said. "You and your three little brothers.
The police held Wagner, and Schlomo eventually testified at the extradition trial, where Wagner admitted he was a Nazi and had served in Sobibor.
"I know what happened there," he told the court. "But I never went to see. I only obeyed orders."
The Brazilian Supreme Court ruled that neither Poland nor Israel had jurisdiction over Wagner, and that Germany's extradition documents were flawed. Wagner was a free man once again."
The problem is that in reality, Wagner confessed that he had been in Sobibor, but that he knew the camp only as an exemplary work camp and that he therefore had no regrets about his days spent there. Things are a bit vague about the extradition trial since not much detailed information on it seems to be available in translation, but according to an article by Mark Weber
For a time, the acting commandant of Sobibor was Gustav Franz Wagner. Some years after the war, he was found living in Brazil and was put on trial there. Jewish witnesses testified in court that he was responsible for 150,000 deaths and took special delight in brutally killing women and children. Wagner, however, swore that Sobibor had been a "model" work camp, not an extermination center. The Brazilian court rejected the prosecution's case and decided to neither convict nor extradite him. Wagner was released in 1979, but was found dead a short time later at his farm, knifed in the chest.

Rashke continues:
"Then, in October 1980, Wagner's attorney announced that the Nazi had committed suicide on the farm in Atibaia where he worked as a farmhand. Shlomo hinted to me that Wagner's death was no accident. Did the Israelis get him? Did Brazil's Kameradenwerk, the Nazi underground, get him? Did the Jews get him? Schlomo declined to explain his cryptic remark.
Schlomo recalled how Tom [Thomas Blatt] had phoned him from California when he had learned that the Brazilian government would not extradite Wagner.
"Can I buy a gun in Brazil?" Tom had asked Schlomo.
"Don't worry", Schlomo had said. He didn't want Tom to do anything rash. "Wagner'll be taken care of."
Tom told me later that he had thought many times about hunting down and killing the Sobibor Nazis. He said he didn't know whether he would have actually done it, but he could have because to him it wouldn't have been murder."
Note that Blatt as well as Schlomo Szmajzner had experience with weapons and warfare. Szmajzner was a partisan after the escape and Blatt served as a military officer hunting down ex-Nazis in post-war Soviet-occupied Poland.

Above: Wagner found dead at the farm in Atibaia. How likely is it that someone would commit suicide through stabbing oneself in the chest?
If Sobibor really had been a extermination camp, why would any "Brazil Nazi network" eliminate Wagner, especially since he was not extradited? Why wouldn't they have killed off him and Stangl way earlier to begin with? Why would a ghostly network of expatriate Nazi geezers have eliminated "the man with the big ears" who wasn't Wagner?
The only scenario that explains the death of the unknown German and Wagner is that of Jewish (Mossad?) agents or assassins hired by them killing off "extermination camp" guards. Let's recall the bragging of the "nazi hunting" Klarsfelds in this context:
On July 24, 1978, at a news conference in Paris following the indictment in Cologne of Kurt Lischka, Serge Klarsfeld stated: "We are not seeking vengeance. If that were our aim, it would have been easy for us to kill all the Nazi criminals we have tracked down." "And if the court in Cologne refuses to try Lischka?," someone asked. Klarsfeld replied: "That in a way would be signing his death sentence" (Le Monde, July 26, 1978, p. 4). In 1982 the Klarsfelds engaged the services of a hired assassin, a Bolivian socialist of Indian origin named Juan Carlos, to assassinate Klaus Barbie (Life, Feb. 1985, p. 65), but the operation did not succeed.
During a 1986 interview with the Chicago Tribune (June 29, 1986), Beate Klarsfeld told "how she haunted at least three former Nazis until they committed suicide or died; how she organized attempts to kidnap others; how she used headline-making gimmicks to bring to trial or to ruin the careers of many who were convinced the world had forgotten them." She related how she slapped the face of German Chancellor Kurt-Georg Kiesinger in public in 1968. "Once, she and several friends tried to kidnap Kurt Lischka" but the operation failed because the car they were using had only two doors. As for Ernst Ehlers, "harassed by Klarsfeld-organized demonstrations outside his home, he first resigned his position [as judge] and then committed suicide."
After picking up the trail of Walter Rauff in Chile, the Klarsfelds organized demonstrations in front of his house and broke his windows. "He died a couple of months later," Beate Klarsfeld told the American daily. "I was glad, because as long as these people are alive, they are an offense to their victims." "My husband and I are not fanatics ... Once my husband held a pistol to the temple of Rauff, just to show that we could kill him, but he didn't pull the trigger."

Blatt's "interview" with Sobibor SS man Karl Frenzel (see http://www.forum.codoh.com/viewtopic.php?t=3674 ) also takes on a new shape in the light of Blatt's words to Rashke.
My guess it that a loose cabal of "nazi hunters" like Wiesenthal and the Klarsfelds in league with Mossad people and maybe also survivors like Schlomo (who likely acted as a sayan, a local trusted assistant of Mossad, in the terminology described by ex-Mossad Victor Ostrovsky in his book By way of deception) eliminated those former "death camp" guards who they did not manage to extradite and put before kangaroo courts (where they would "confess" to the gassings). They would have an extra incentive in the case of Wagner, who seems to have denied the established view of Sobibor as a "death camp" in his extradition trial. If not eliminated, he might pose a threat to the gas chamber legend. This hypothesis could also explain the "suicides" while under arrest of some of the ex-guards brought before "trial" in West Germany during the 50's and 60's or earlier, such as Kurt Bolender (according to death-camps.org "During his trial he constantly maintained that there were no sick and cripple people executed in Sobibor - only when he was cross examined he admitted that everything was true."), Friedrich Tauscher and Hermann Felfe.
