He is noted as KIA, and I guess the only way to get his first name is to:
1. Locate his Grablage (the Volksbund does not have him on their website/in their database)
2. Check with WASt
The entire loss record is as follows:

The reason for the (2) in the pilots name is that there are multiple persons with the family name Hase and no given name in my database.
