I did some more research on this guy:
He was a Hitler youth and he worked anti aircraft guns from 1943 until the end of the war.
I think we might be looking at the antichrist himself. I'm not totally religious myself but I do know a little about this subject. According to the bible, the antichrist will appear out of Rome and will befriend Jews. But in the end, he slaughter's them. Who better to slaughter jews then a former Nazi haha. Anyways, something interesting I found.
