Hi,
Larry thank you for your kind words, but I think I'm still far from being an expert.
I've checked my correspondence that I had with Raus about two years ago regarding this He 111 and came across a few names. Another source mentioned Fw. Rahm, Uffz. Horch and Bucholtz (unknown rank) as being killed in that crash. According to the same story, another crew member named Janssen should have benn taken prisoner by the partisans. I couldn't find anything that would connect any of these names to an aircraft crash. The Volksbund site provides as well no clues.
