At least 14,000 people were imprisoned in Tuol Slen (Tool Sleng) prison, also called the S-21, which was one of the most prominent of many interrogation houses throughout Cambodia during the Khmer Rouge’s four-year reign of terror. Virtually, every one of them was killed and, it turns out, photographed by a teenage Khmer photographer.
