LW crash outside Paris August 1. 1940
 

Hello!
I am searching the circumstances about a crash just outside Paris on the first of August 1940.
The pilot, Uffz. Martin Sigllechner, was killed. He had participated in the campaign in Poland and in the battle of France, and was awarded EK II.
Furthermore I know he was in a Kampfgeschwader.
If possible, I would like to know the aircraft code and Wnr. and also the names and fate of rest of the crew.
Thanks in advance.
