Based on the investigations conducted up to that moment, on May 17, 2005, two young “gang members” nicknamed “El Queso” and “El Gato” were suspected of material involvement in Mr. A.A.’s death. 179 Also, based on statements made by S.Z. in 2006 (supra para. 112) a possible new hypothesis emerged in the investigation, namely that the death of A.A. was due to the fact that he had witnessed the killing of a young man in the area, and the suspects were four individuals nicknamed “El Gato”, “Susy”, “Salomón” and “Chelelo.” 180 Furthermore, based on the statement of M.I. made in 2007 (supra para. 112) two other individuals, known as “Nito” and “Selvin,” were implicated in the crime . 181 114. On June 12, 2006, the prosecutor in charge submitted a report on the investigation to the Executive Secretariat of the Public Prosecution Service, stating that in several interviews with the victim’s relatives he was informed that “on one occasion the deceased was threatened by Mr. [L.L.], though there are no signs of his involvement in the matter.” The report added that “a group of criminals opera[ted] in the community […], who could be involved in [Mr. A.A.’s] death, as possible perpetrators […] since they were implicated in other local crimes in which some individuals [had] died” and therefore ballistic tests would be carried out to compare this case with others that occurred in that sector. 182 For his part, on August 1, 2006, the investigating agent sent the Assistant Prosecutor a report on the desk-based investigations of crimes committed in the area in which A.A. was killed, and which could be connected with his death. The report referred to six cases corresponding to a period between October 2004 and May 2006. 183 115.
