Tuol Sleng Genocide Museum (TSGM) is a former Khmer Rouge extermination center known as S-21, where thousands of lives were perished. This secret prison was the main interrogation, torture and extermination site of the Khmer Rouge regime between 1975 until 1979. After the end of the regime, the site was found with thousands of documents were left on-site. Those documents consists of photos, confessions, biographies and other related documents which are very important to present as evidences for the crimes committed by the Khmer Rouge. Beside the legal confrontation, those above-mentioned documents also used as a crucial information for the family searching after the regime ended. After publishing the documents left from S-21 online (please go to: http://archives.tuolsleng.gov.kh) in early 2021, TSGM has recently renewed efforts
to get in contact with families of S-21 victims by capturing their lives prior to their detention at S-21 of a minimum of twenty prisoners of S-21 by gathering information from their relatives and from TSGM archives.
