Citing a September 1945 letter from the FBI (one of the documents declassified in the Nineties), Weschler points to the lines that show that the FBI believed that if Hitler got into trouble, he could always find a safe haven with the Eichhorns if he could manage to get there. Weschler found former employees of the hotel who say they met and waited on Hitler after the war there.

“It was easy for them to recognize him, because his picture was all over the hotel,” says Weschler. He says that his research shows that Hitler moved on from the hotel to an isolated rural estate in Argentina, where he lived out his days with Braun and their two daughters, and that he died in the mid-Sixties.

Particularly persuasive evidence, according to Weschler, is DNA testing done in 2009 on Hitler’s skull fragments that were recovered from the bunker.

“They showed that they couldn’t have been Hitler’s skull because they were from a woman under 40,” says Weschler, a finding that was reported in the mainstream press.
