Death of Jürgen Brocke 4./JG 77 in Sept, 1942

[Csaba B. Stenge]

I am looking for the exact cause of the mentioned pilot's death. I know, where he crashed exactly and his plane, Wnr, etc, but the loss report from RL mentioned, that he was shot down by fighters, Prien's book mentions, that by AA fire. I forgot to check the story of the JG 77's KTB. Anyone knows, what happened with him exactly (and when he was born exactly)?

Thanks in advance,

Csaba
