Tuol Sleng Genocide Museum - Prison Staff

The documentation unit was responsible for transcribing tape recorded confessions, typing the handwritten notes from prisoners' confessions, preparing summaries of confessions, and maintaining files. In the photography sub-unit, workers took mug shots of prisoners when they arrived, pictures of prisoners who had died while in detention, and pictures of important prisoners after they were executed. Thousands of photographs have survived, but thousands are still missing.
