37 of the FAFG identified the grave, which was part of a clandestine cemetery where the human remains of Medardo Juárez and others were exhumed and identified. 123 B.20. Disappearance of Marcelo Sic Chen in December 1984 118. Between December 13 and 15, Marcelo Sic Chen arrived at the colony of Chichupac in order to seek “amnesty and turn himself in.” There, he was received by a military commissioner who handed him over to members of the National Army. He was then taken to the military post in Rabinal and to date his whereabouts are unknown. B.21. Execution of Silvestre Sic and Raymunda Corazón on December 20, 1984 119. On the morning of December 20, 1984, a group of soldiers and members of the PAC entered a house in the village of Chichupac where Silvestre Sic (or Silvestre Sic Xutumul), father of Marcelo Sic Chen (supra para. 118), and Raymunda Corazón (or Raymunda Sical Corazón)were staying, and executed them with firearms. Their mutilated bodies were found the following day by neighbors who proceeded to bury them in a latrine near their home. 124 In 2002, members of the FAFG identified the grave, which was part of a clandestine cemetery. During the exhumation process, one of the corpses was identified as Raymunda Corazón by Francisco Sic Chen; however, the forensic anthropological report states that it was not identified by the expert analysis. On the other hand, the remains of Silvestre Sic were exhumed and identified by means of the expert analysis. 125 B.22. Execution of Efraín García de Paz on August 17, 1986 120. Efraín García de Paz, brother of Juana García Depaz, was away from the area for approximately three years. When he returned, on August 17, 1986, on the way from his home in Chichupac to the municipal seat of Rabinal, he was intercepted and executed. According to Juana García Depaz, the person who killed her brother was a civilian patrolman, although she has also indicated that it was a “G2” of the Army. However, the Inter-American Commission concluded in its Merits Report that it was a “judicial officer.” According to Juana García, she and her relatives collected Efraín García’s body and buried him in the cemetery located in Rabinal. 126 C.
