Under the Khmer Rouge regime, Kaing Guek Eav, known as Duch, directed the M13 prison for four years, before becoming the head of S21, the terrifying death machine that eliminated Khmer Rouge opponents. Some 12,280 Cambodians met their deaths here. In July 2010, Duch was the first Khmer leader to appear before an international court, which sentenced him to 35 years in prison. He appealed the sentence. While Duch waited for his new trial, Rithy Panh questioned him in depth.
