38 murder, but the authorities did not wish to undertake any investigation, mainly due to the risk involved. There is a proceeding opened against other direct perpetrators. It is an obligation of the State to continue the investigation and to try all those who are responsible, for justice to be served in the instant case. In 1994, a set of cassettes recorded by Noel de Jesús Beteta Álvarez was handed over, in which he describes exactly how he murdered her sister, and he clearly defined how the illegal intelligence operation was carried out to kill those who were deemed enemies of the State. Through his statements, he sought redemption of the sentence. In any case, he expected an amnesty. He stated that the person who gave the order and who gave the “Roman” signal to kill her sister was colonel Juan Valencia Osorio, who had received instructions from general Edgar Augusto Godoy Gaitán. At the trial that took place from September 3, 2002 to October 3, 2002 before a competent tribunal, Beteta Álvarez recognized that it was he who did the interviews, but that he did them under the influence of drugs, and he accused her of supplying him a daily ounce of cocaine to buy his testimony. Nevertheless, the statements are consistent in terms of space, time and place, so that if Beteta Alvarez were drugged due to consumption of a daily ounce of cocaine for six or four months duration of the interviews, he would not have been capable of making them. Her family, her sister’s colleagues at AVANCSO and the staff of the Myrna Mack Foundation have been threatened. The pattern has always been to threaten after a judicial step has been taken.

Once, they asked the Government of the Republic to appoint an investigative prosecutor´s office to look into threats against human rights advocates, and they submitted a project on how to investigate those who threaten, including the legal operators. However, there has been no response. She had to move to a condominium with a guard service to ensure that entry of individuals to her residence is more adequate. There are security guards and high walls to avoid any control. No one likes to live with security because one never knows when one is betrayed by someone who passes on the information, especially due to their longstanding struggle in this case. She has been emotionally affected by living with so much anguish and uncertainty. The State has resorted very much to psychological warfare. The attitude of the State of Guatemala at this Court was rather a tactic of psychological warfare. The Agent of the State was a witness in her case and now they want to turn him against her, resorting to the same delay tactics in the international proceeding that they used in the domestic one. For her family to avoid falling apart and to remain steadfast in their struggle to obtain justice, each one had to go through an individual process. Her sister’s case is a paradigmatic one not only for her family but also for many Guatemalans who see
