I'd check with the VA office for the Bmt area or call the local VFW hall there. I'd do it for you but, I'm living in TN now. I'm working on a project for local Iraq dead from here, we called the VA and they provided us with a list. Once you have a list of those who've died locally, it should be too hard to compare it to student rosters from SP if you have them available. Also, you could call the Beaumont Enterprise as well as the local news stations and ask them run a news item requesting families of former students to contact you with the information.

On a side note, if you are able to get the school building a property saved, you might look into a memorial on the site for same purpose.

I'm sorry I'm so far away and not of much help.
