I'm looking for any info (career, other units, etc.) on Hauptmann Heinz Bollhorn (DOB 7 September 1913, Altona), possibly 2./KG66's last Staffelkapitän.

Hptm. Bollhorn was mentioned as Vermisst/Missing in Action since April 1945 on Vermisstenbildliste LH622 of the Deutsches Rotes Kreuz - Suchdienst München. According to info I have he could have crashed in an American AAA site while attacking a pontoon bridge in the Magdeburg - Schönebeck a.d. Elbe area on the 14th of April 1945.

Questions I have:

1. Is he still considered missing or does he have a known grave by now?
2. Does anybody know if the following persons, who are also MIA around that time, were part of his crew:
   1. Franz Lennartz (DOB 30 August 1920, Alsdorf)
   2. Gerhard Losse (DOB 15 January 1921, Reideburg)
   3. Karl Walter Spruck (DOB 26 December 1918, Mannheim)

Thanks in advance,

Marcel
