In July 2011, the indigenous organization "Waqib Kej" presented a letter to the United Nations accusing Pérez of involvement in genocide and torture committed in Quiché during the civil war. Among other evidence, they cited a 1982 documentary in which a military officer whom they claim is Pérez is seen near four dead bodies. In the following scene, a subordinate says that those four were captured alive and taken "to the Major" (allegedly Pérez) and that "they wouldn't talk, not when we asked nicely and not when we were mean ["ni por las buenas ni por las malas"]."
