It would seem he was under investigation by the Reichsmarshal's Office for "hoarding" certain artifacts found at the castle (true, considering the amount of treasure B.J. discovers). However, Major Jurgen swiftly denied the accusations in his reply.
He also had a rather heated confrontation with Oberst Helga von Bulow over the level of security at Castle Wolfenstein. The argument apparently left him quite shaken. He is mentioned in several in game pieces of intel found in the castle as well as in conversations between his troops overheard by BJ. He is presumed to have been killed during BJ's escape.
