Served with A/4/503 April 67 – April 1968 on my second tour

Looking for a LT Cully ( I hope I have his last name correct) 3rd platoon leader A/4/503 The Lt stepped on a mine while searching a village near Tuy Hoa September 1967 and was shipped to Walter Reed . He and I were very close but have not been able to locate him since that day at Tuy Hoa. Anyone reading this with knowledge of him please contact me.
