By that time, Pol Pot—Khmer Rouge architect and lead executioner—had been dead for nearly a decade. A royal pardon allowed his brother-in-law, Ieng Sary—co-founder of the Khmer Rouge and mastermind of torture and mass murder—to travel on a diplomatic passport and enjoy both a homestead in Pailin, the former bastion of Khmer Rouge leaders, and his lavish villa in Phnom Penh. Sary, the man Pol Pot called Brother No. 3, was apprehended in 2007 and died this past March while standing trial in Case 002 for crimes against humanity, war crimes, and genocide.
