On a hill overlooking Sammy's hometown in Greensburg, Kentucky

Len Nagel: "I was TDY with Sammy on that fatal day. He had volunteered to go on a "Search and Destroy" mission with a MACV Major. Both were killed when someone hit the trip wire and set off a bouncing betty mine. I still can remember hearing the chopper and someone asking if I had known Sammy Martin and I remember saying yes, "I know Sammy". That's when I identified his body."
