I believe this man is another possibility for the crew, Donald M Wolberg.
Search for Wolberg on this link:

I have found another articles that mention he was in the 322nd BG and was in action in April, 1945. Several articles mention he was wounded, apparently in April and was "released", with some confusion as whether he was a POW.
This next link, (search for Wolberg) shows him on crew #39D in the 322nd. Interesting that none of the crew listed seem to have been with Wolberg at Cologne.
