Hakan,
No direct verification myself, but perhaps this website is useful for the 1st FG losses:
http://www.mts.net/~royb/1stfghonor_roll.html
Please note both Rodolff and Hartwig were POW, not KIA (see POW section on
http://aad.archives.gov/aad/series-list.jsp?cat=WR26)
P-38 42-67093 is also linked with 1st Lt Dalphon C. Kenney instead, lost on 28-3-1944, north of Rijeka. He was with 154th TRG and returned.
As for Lt David Weber, 82nd FG website says he was killed in a flying accident on 28.3.44, non-combat related...
Regards,
Leendert
