Photojournalist Dith Pran risked his life to help New York Times reporter Sydney Schanberg tell the world about Cambodia's fall to the Khmer Rouge in 1975, then became a prisoner of the barbarous regime, under which as many as 2 million Cambodians were killed. Through guile and sheer desperation, Dith survived for more than four years before escaping through what he famously dubbed "the killing fields" -- horrifying clusters of corpses that littered the countryside. His story inspired a 1984 movie that gave him an eminence he tenaciously used to press for his people's rights. He died Sunday in New Jersey of pancreatic cancer. He was 65.
