it’s been rumored since time-immemorial, or at least since 1945. Yet a new documentary opens up the rumor mill again, saying that Adolf Hitler, did not commit suicide in his Berlin bunker as normally believed, but instead lived his days out in Argentina.

Speaking on Sunday, director/producer Noam Shalev and researcher Pablo Weschler revealed their reasons for believing that their evidence proves — though not to 100 percent certainty — that Hitler did not die in 1945.

Shalev admitted that

We will never know the truth. But there is enough evidence to build an alternative theory about what happened to Hitler.

Weschler added,

No one believed the Russians’ story of Hitler’s suicide in the bunker. As early as the summer of 1945, there were headlines asking, “Where is Hitler?” all over the world.

In the documentary, “Hitler in Argentina,” the filmmakers say that Hitler lived out his last days in an luxurious Argentinian hotel. Their new documentary is set to be released sometime in 2013.

The urge to complete the documentary came with recently declassified FBI documents. Shalev and Weschler had ong believed that British intelligence officer and historian Hugh Trevor-Roper’s investigation into Hitler’s death was “unprofessional,” since the Russians did not allow access to many forensic investigators.

Weschler said:

In those days, the FBI, not the CIA, was responsible for South America. And in declassified documents, we see that the FBI took very seriously the possibility that Hitler fled to Argentina.

Additionally, the documentary notes that the FBI was so concerned that the possibility that Hitler was in South America was viable, the agency created a special task force to investigate it.

The filmmakers believe that they can determine Hitler’s exact whereabouts after World War II. They used a book entitled “Hitler’s Escape,” written by Italian journalist Patrick Burnside as a guide for their movie.

For Shalev and Weschler, the most significant evidence comes in the form of DNA testing done on Hitler’s skull fragments in 2009, fragments that were recovered from the Berlin bunker. Weschler said:

They showed that they couldn’t have been Hitler’s skull because they were from a woman under 40. The more you look into it, the less credible the official version becomes, and the more plausible an alternative theory seems.

It’s true, though, that Eva Braun was only 33 at the time of her reported death, in the same Berlin bunker. Could the DNA evidence simply have been mixed up?

There is more evidence, Weschler said:

The Eden Hotel in La Falda, Cordoba [in Argentina] was owned by Ida and Walter Eichhorn, who were close friends of Hitler. Hitler sent them a Mercedes Benz as a gift. It was the first Benz in Argentina.

Among the FBI documentation that Weschler and Shalev accessed was an FBI letter from September of 1945, in which the agency said it believed the Eichhorns would provide Hitler shelter if he ever needed it. Weschler also claims to have found former hotel employees who say they met Hitler and waited on him after the war.
