That was a crew chief named Don Williamson, Jim. I don't think I knew him; I left in June of 1969. He was pulling maintenance on his ship in the An Khe Swamp when the bad guys pulled the trigger.
Mixer was there and wrote me about it, my 21st birthday, 11/15/1969. They found out later that the dinks had been occupying an empty hooch for some days before they acted.
