On the night before our son's wedding, we were in a hotel room in Atlanta.  We got a text from someone named Mike.  He had gone to school with Warnie and had been looking for him also.  He had the advantage of knowing his first name.  The frustrating part for me helping Richard find his buddies is that they were called Red or Low Dog, Ski or Jonesy.  No first or last names. Even with modern technology it was hard to find people by a nickname.  Richard was called Nick or Biggun.
But that night with Mike's email,we were able to contact Warnie.  We were both so excited.
Richard had always wondered if Warnie made it out of Vietnam alive.  He was in very bad shape when he last saw him.  He was hit and he couldn't breathe due to his own blood choking him.  He had his artery on the side of his neck bleeding so badly it was shooting out .  A black solder was putting pressure on his neck.
Richard got instructions from the corpsman who left him with the tube and Richard did a tracheotomy  on him.  There were so  many people dying, the corpsman could not get to everyone.  Warnie married a nurse who worked at the hospital where he recovered and they have 5 kids
