62 complexity of this type of facts and the structure in which the people probably involved in the same are located, pursuant with the context in which they occurred, thus avoiding omissions in the gathering of evidence and in the follow-up of the logical lines of investigation.209 207. On the other hand, in relation with the determination of the whereabouts of Mr. Rosendo Radilla-Pacheco, the Court verifies that within Preliminary Inquiry 26/DAFMJ/2001 (supra para. 185), on May 15, 2001 a cabinet inspection was carried out in the yard of a property located in Tres Pasos del Río, Municipality of Atoyac de Alvarez, Guerrero, during which they found, among other things, bone fragments that were identified as non-human, prior expert reports in the fields of criminal sciences, photography, and anthropology.210 In this regard, the representatives stated that said diligence was carried out “[w]ithout informing the next of kin” and “[u]nexpectedly” during the night. They argued that an excavation where they found bone remains, was carried out and that these were collected “[w]ithout any care or protection whatsoever,” and that they were taken destroying “[t]he forensic anthropological context.” Likewise, they stated that “[t]he next of kin did not have trustworthy experts [and that] after some time they informed them they were animal remains, leaving the next of kin with serious doubts because of the way in which the diligence was carried out,” and because those who were present, such as Mrs. Tita Radilla, saw pieces of clothing around the remains.” The State did not make any specific reference to this matter. The Court considers that the facts mentioned by the representatives have ben established, since they can only be disproven through the case file of preliminary inquiry SIEDF/CGI/454/2007, which the State should have forwarded but refused to do so (supra paras. 88 through 92). 208. Likewise, it shall be pointed out that it was not until six years later that new diligences were carried out with regard to the search for the whereabouts of Mr. Rosendo Radilla-Pacheco, specifically, in what is currently known as the “city of services”, at the property of the Municipal Council of the City of Atoyac de Alvarez, Guerrero, and where the Military Barracks of Atoyac de Álvarez were previously located. The State made reference to the diligences carried out in this sense since October 22, 2007.211 Similarly, the witness Martha Patricia Valadez Sanabria mentioned a series of diligences that were practiced as of December 4, 2007. The State indicated that during the last excavation diligences non-human remains were found, and that the latter was informed to Mrs. Tita Radilla and the archeology expert accredited by her. The execution of those excavation diligences can also be concluded from the statemente offered by Mrs. Valadez Sanabria.212 209 Cf. Case of the Serrano Cruz Sisters v.
