Cambodia’s Killing Fields The Documentation Center of Cambodia (DC-Cam) uses global satellite position mapping combined with fieldwork to document mass graves nationwide. To date, it has identified over 388 genocide sites containing more than 19,000 mass graves
(these are defined as any pit containing 4 or more bodies, although some graves hold over 1,000) dating from the Khmer Rouge regime (1975-1979). The Center has documented 197 prisons from Democratic Kampuchea and 81 genocide memorials. (Data was collected by Pheng Pong-Rasy and his team).
