Hi,Evidently, the NARA site doesn't have Delbert E. Cox'sinformation.That is why you are not finding anything.That site does not have every man's information.And that may be due to his records being part of those that burned in 1973.
Have you written for the details of his death?You can, but be aware that what you might received is quite graphic.Here is the address to write to.
U.S. Army Human Resources Command ATTN:AHRC-PAO (FOIA) 200 Stovall Street Alexandria, VA 22332-0400
Be sure to mention Freedom of Information Act in your letter to them and supply as much information to them as you can.
I found where he is buried and that is probably because Marybeth posted it.
