Tim,
I believe I located information on Gary A. Crosston of Elkins, W.V,. however it is sad news. I found an obituary in a W.V. paper stating that he passed away on 30 Aug 04. The obit stated that agent orange was the cause. He was with the 7/17 Air Cav "Ruthless Raiders" when he was in VN. If you want I will back channel the obit to you.
Sorry for the bad news.
