37 “pileteada” (consisting in immersion in a tank with water, blood and human excrement,36 often until the victim drowned). 61(36) Carlos José Mancuello Bareiro remained detained for 22 months. Regarding the tortures to which he was subjected, Jorge Pane Zárate, who was an officer in the Asunción Police Investigations Department at the time of the facts, saw him while he was detained on these premises and confirmed that “he appeared to have suffered unlawful coercion, because […] the so-called 'Constitución y Teyú-yuruguai,” a short whip of plaited leather, about a meter long … left very visible marks, and he was bruised and swollen.” 61(37) Gladys Meilinger de Sannemann, who was detained in the offices of the Investigations Department in 1976, saw Carlos José Mancuello Bareiro and Benjamín and Rodolfo Ramírez Villalba during this period, because she was able to observe them every day in the early morning when they went to the bathroom. The last time she saw them alive was on September 21, 1976, when she was transferred from these premises to the Emboscada prison. 61(38) Mrs. Bareiro de Mancuello, Carlos José Mancuello Bareiro’s mother, periodically sent him clothes, food and medicine. She also received his dirty clothes from the police to wash them and return them to him. As of September 21, 1976, Mrs. Bareiro de Mancuello no longer received the clothes of her son, Carlos José Mancuello Bareiro, from the police with the explanation that he was no longer in the Police Investigations Department or that he had escaped from there. 61(39) The logbook of the Investigations Department for 1976 states that, on inspecting the cells on the night of September 21, 1976, it was verified that “four of the detainees had escaped.” The Investigations Department’s ledger of “Entry and Departure of Detainees” states that Carlos José Mancuello Bareiro had “escaped” and, regarding the brothers Rodolfo and Benjamín Ramírez Villalba and Amílcar Oviedo, the space by their names corresponding to “Departure” was left blank.37 Also, an official document from the Guards Office of the Investigations Department addressed to the Head of the Investigations Department, Pastor Milciades Coronel, reported the alleged escape of Carlos José Mancuello and Benjamín and Rodolfo Ramírez Villalba. This was subsequently confirmed by the statements of several of the investigation officers present that night, who were called on to testify in the trials opened with regard to the case after 1989.38 61(40) However, based on the statements of several former police officers, the No. 1 Criminal Tribunal [de Liquidación y Sentencia] came to the following conclusions (infra para. 69): At approximately 10.30 p.m. [on September 21, 1976] […] the detainees, MANCUELLO, OVIEDO and the brothers RAMIREZ VILLALBA, were ordered to get ready because they were going to be transferred to another place […]; then, they proceeded to transfer the four detainees to a VW Kombi vehicle […] which was waiting outside the building […] without anyone being informed of their destination.
