Analysis of 20,000 mass grave sites by the DC-Cam Mapping Program and Yale University indicate at least 1,386,734 victims of execution.[1][2] Estimates of the total number of deaths resulting from Khmer Rouge policies, including disease and starvation, range from 1.7 to 2.5 million out of a 1975 population of roughly 8 million. In 1979, communist Vietnam invaded Democratic Kampuchea and toppled the Khmer Rouge regime.
Cambodian journalist Dith Pran coined the term "killing fields" after his escape from the regime.[3] A 1984 film, The Killing Fields, tells the story of Dith Pran, played by another Cambodian survivor Haing S. Ngor, and his journey to escape the death camps.
