Today I got his death records. Seems "two insignias" were sent home with his effects- I suspect the two 115th DI's I have. Creepy. Also of note was that it was apparently a gunshot wound to the head.
The other nice thing is that the paperwork listing his body's return has told me what cemetary he is burried in. So I shall have to go visit. Poor kid (and mom). His dad was dead, and there are a number of letters from his mom asking for info, or help, or "when will you bring me back his body?"
