That is what I understood to have happened, “but” even the evidence of working at the “other” camp was shoddy at best, and with the KGB forging the original ID documents, it would be difficult to place credibility on some “new” “new” evidence.
If the KGB forged stuff, why wouldn’t the East Germans forge things as well?
The so called evidence that caused his first conviction to be overturned was a mystery witness who claimed they saw the name Marchenko instead of Demjanjuk on a piece of ID. The Israeli Supreme Court didn’t hear when they reviewed the case that Demjanjuk had used the name Marchenko on his US entry visa way back in the 50s and Marchenko was his mother’s name, so there was even a connection to that name, but the connection doesn’t clear him.
Forgeries can be detected. Unfortunately there was non-Soviet documentation as well, and the document which cast doubt on his identity as Ivan the Terrible was among the “forgeries”. Can’t have it both ways.
