South Vietnamese National Police Chief Brig Gen. Nguyen Ngoc Loan executes a Viet Cong prisoner with a single pistol shot in the head in Saigon Feb. 1, 1968. Nguyen died Wednesday, July 15, 1998 at his home in Burke, a suburb of Washington, D.C., after a battle with cancer, said his daughter, Nguyen Anh. He was 67. This photo of Nguyen aiming a pistol point-blank at the grimacing prisoner's head became a memorable image of the Vietnam War.
