My Lai Massacre Hero Thompson Dead
Thompson, whose role in the 1968 massacre did not become widely known until decades later, died at the Veterans Affairs Medical Center in Alexandria, hospital spokesman Jay DeWorth said.
Trent Angers, Thompson's biographer and family friend, said Thompson died of cancer.
"These people were looking at me for help and there was no way I could turn my back on them," Thompson recalled in a 1998 Associated Press interview.
Early in the morning of March 16, 1968, Thompson, door-gunner Lawrence Colburn and crew chief Glenn Andreotta came upon U.S. ground troops killing Vietnamese civilians in and around the village of My Lai.
They landed the helicopter in the line of fire between American troops and fleeing Vietnamese civilians and pointed their own guns at the U.S. soldiers to prevent more killings.
