Pichilingue Guevara, Intelligence Operative Technician 3rd Class Eduardo Sosa Davila (aka "El Chato"), Nelson Carbajal García, Juan Supo, José Pino, individuals known as "Petete" and "Rambo," and others not identified. 7. The petitioner claims that in the predawn hours of 18 July 1992, armed, hooded members of the Army Intelligence Service (SIE) and the Army Directorate of Intelligence (DINTE)–Santiago Martín Rivas, Eduardo Sosa Davila, Eliseo Pichilingue, Nelson Carbajal García, Juan Supo, José Pino, Manuel Guzmán Calderón, and others, most of whom were members of the Colina Group–burst into the students’ and faculty members’ residences of the Enrique Guzmán y Valle National University (La Cantuta). Together with them was Lt. Aquilino Portella Nuñez or Julio César Estrada of the army’s Special Forces Directorate (DIFE), the head of the Civic Action Base stationed at the university. Also involved in the operation were Peruvian troops from the Special Forces Directorate’s BIG-19, led by Maj. Manuel Guzmán Calderón, who cordoned off the university residences to facilitate the abduction. 8. The petitioner reports that once inside the residences, the troops forced all the students to leave their rooms and lie belly-down on the floor. One soldier then pulled up each student’s head by the hair and separated those who were to be detained. This was carried out with assistance from Lt. Aquilino Portella Nunez or Julio César Estrada of the army’s Special Forces Directorate (DIFE), the head of the Civic Action Base stationed at the university, who knew the students and was carrying a list of those who were to be detained. The students detained were Bertila Lozano Torres, Dora Oyague Fierro, Luis Enrique Ortiz Perea, Armando Richard Amaro Condor, Robert Edgar Teodoro Espinoza, Heráclides Pablo Meza, Felipe Flores Chipana, Marcelino Rosales Cárdenas, and Juan Gabriel Mariños Figueroa. 9. The petitioner states that in the faculty residences, troops violently entered the home of Professor Hugo Muñoz Sánchez by climbing over the yard wall and destroying the service entrance. They then gagged Prof. Muñoz Sánchez and covered his head with a pair of black trousers. Some of the assailants searched Prof. Muñoz Sánchez’s bedroom and, at the same time, prevented his wife from leaving that room. Prof. Muñoz Sánchez, bare-footed and barechested, wearing only a pair of trousers, was then carried away by the soldiers. The operation was filmed by one of his captors. Between Prof. Muñoz Sánchez’s home and the gateway to the faculty residences, some witnesses, including Mr. Octavio Mejía Martel and his wife, tried to intervene on his behalf but were forced to withdraw at gunpoint. 10. The petitioner reports that the soldiers then left the university, taking with them Prof. Muñoz Sánchez and the nine students Lozano Torres, Oyague Fierro, Ortiz Perea, Amaro Condor, Teodoro Espinoza, Pablo Meza, Flores Chipana, Rosales Cárdenas, and Mariños Figueroa. The victims were immediately taken to a site outside the city and, in a totally defenseless state, were tortured and then, while kneeling were shot to death in the head from behind. 11. According to the petitioner, the victims’ bodies were clandestinely buried and covered with quicklime in three graves in the area known as Cerro Santa Rosa, at kilometer 1.5 of the Ramiro Priale highway, on land belonging to SEDAPAL. Following a public complaint later made by congressman Henry Pease, the perpetrators of the killings dug up the bodies, burned them, and moved them to other clandestine graves located in Chavilca, Cieneguilla. 12. The petitioner alleges that on July 12, 1993, the magazine Sí, edited by Ricardo Uceda, published a sketch indicating the place where some of the remains of the La Cantuta victims had been buried. The public prosecutor’s office then conducted an investigation in the Chavilca gully in Cieneguilla. This investigation revealed the presence of four clandestine graves containing bones, most of them charred; in two of the graves, two sets of keys, a spent bullet, remnants of clothing, hair, etc., were found. Again, following a complaint made by the editor of Sí magazine, the public prosecutor conducted an investigation at Km 1.5 of the Ramiro Priale highway, on land belonging to the SEDAPAL company’s La Atarjea Treatment Plant. On that site, which had up until then been used as a firing range by the Peruvian National Police, additional clandestine graves containing bones (one complete clothed human skeleton, a half 2
