After 60 or more years, I think this is a dead end. The US Army investigated and considered that an accident. Perhaps the brakes failed...who knows?

Demjanjuk is as innocent until proven guilty, and guilt is far from established.

Even the German prosecutors' "witnesses" are unreliable German Nazi psychopathic killers.

Who would believe octogenarian German psychopaths who are shameless, remorseless, admitted, and avowed SS murderers?
