2003, the individuals who had presumably murdered Mr. Castillo had died in a confrontation, and that one of them was a member of a group of people arrested on September 12, 2003 and linked to the information on paramilitaries who traveled around in a truck (supra para. 72).93 157. In relation to the above, the authorities carried out the following actions: they monitored the truck mentioned, they contacted the person who appeared as its owner and carried out expert tests on the vehicle and its license plate (supra para. 58). Also, after the alleged passengers of the vehicle were arrested in a police operation, they were “interviewed”. The statements taken on that occasion indicated that paramilitaries had allegedly participated in the events, that Mr. Castillo had been on a list of people to be “eliminated”, and that the aforementioned paramilitaries had been in contact with Venezuelan State authorities, specifically with members of the National Guard and with the Mayor of Machiques (supra paras. 59 and 60). Subsequently, they “interviewed” an employee of the Vicariate, asking her if she knew the individuals who had been arrested (supra para. 67). Also, in relation to incident of November 20, 2003, the authorities showed photographs of the bodies of the individuals killed on that date to Mrs. Moreno, who said she could not be certain whether any of them took part in the attack against her husband, her son and herself (supra para. 74). 158. Among the investigative measures ordered by the authorities, and not carried out, are the following: 1) photographic identification of the individual allegedly involved in the attack against Joe Castillo and his family (supra paras. 81 and 82); 2) obtaining photographs taken while alive of the individuals killed on November 20, 2003 (supra para. 76), and 3) ballistic comparison between the weapons seized from the individuals killed in the confrontation on November 20, 2003, with the shells of the bullets that struck Joe Luis Castillo (supra paras. 76 and 84). As to the ballistic comparison of the weapons seized from the person allegedly involved in the attack against Joe Castillo and his family, with shells from the bullets that struck Joe Castillo, from the body of evidence it appears that this procedure was indeed carried out, and that the execution of such a measure is recorded in the expert reports issued nearly one year after it was requested (supra para. 84). It should be noted that the Commission stated that this procedure had not been carried out. 159. Furthermore, it is not apparent from the evidence that the authorities in charge of the investigation ordered actions to investigate the accusations made in the police “interviews” held in September 2003 (supra paras. 59 and 60). These accusations alleged links between the presumed perpetrators of the murder of Joe Castillo and certain persons: the Mayor of Machiques, members of the National Guard, “leaders” of a group of ranchers and people belonging to Colombian paramilitary groups presumably “hired by […] cattle ranchers from the area.” Furthermore, the Court takes note that following the order to archive the case on November 28, 2006, as mentioned by the then Ombudsman’s Delegate in the State of Zulia in the respective official letter addressed to the 20th Prosecutor’s Office, a person alleged on May 18, 2007, “that the […] Mayor of Machiques was the mastermind behind the killing”, and that person was summoned to an “interview” nearly three years later, on July 27, 2010. Although this summons was reiterated nearly a year later, on May 19, 2011, there is no record that such an “interview” actually took place (supra para. 96). 93 The identity of one of the individuals arrested on September 12, 2003 and one of those killed on November 20, 2003 appears in a police report dated September 15, 2003. 40
