Looking for Info on a Liaison Pilot

[L_bird Recon]

I'm researching the history of a liaison pilot ( S/ Sgt. John L. Scala , 32 389 401). U.S. Army Air Corps records appear to indicate the Sgt. Scala was KIA in Dec. 1943, however other information suggesting that he survived and was transferred to northern Europe as a liaison pilot. He was later KIA on a photo reconnaissance mission over or near Luxemburg in 1944.

Any suggestions on places to look or any information specific to Sgt. Scala would be greatly appreciated.

Thank you
