89 with organ trafficking.387 The crime of homicide continues to fall within the jurisdiction of the state Attorney General’s Office (also referred to as the “PGJE” for its name in Spanish).388 354. The Commission alleged that “when the Office of the Attorney General of the Republic retained the case files in exercise of its right to jurisdiction (atraccion), there was no procedural or investigative activity of any kind.” The representatives considered that this line of investigation “was considered implausible,” “spurious”; that it had “given rise to morbid curiosity and sensationalist journalism” and that, “after four years, […] it had contributed nothing to the investigation of the [Cotton Field] murders.” In addition, they stressed that “there was never any connection between the federal preliminary investigation and the proceedings filed against [Mr. García and Mr. González].” 355. The State alleged that, during the investigation into organ trafficking, “273 expert appraisals were prepared on forensic medicine, forensic genetics, identikit pictures, social work, psychiatrics, graphoscopy, polygraphy, photography, criminology, criminalistics, psychology, dactiloscopy, audio, forensic stomatology, facial reconstruction, identification, compilations of newspaper Articles, inspection with a binomial sensor, victimology, chemistry, and forensic anthropology. Moreover, 737 sworn statements before the Public Prosecutor’s Office (declaraciones ministeriales) were taken, 246 inquiries were made of the Federal Investigation Agency, 2 international court hearings were attended, and 43 rogatory letters were issued to support the Office of the Attorney General for Chihuahua.” It also indicated that “[t]he material arising from the measures taken by the PGR [Office of the Attorney General of the Republic] was incorporated into re-opened preliminary investigation No. 27913/011.” 356. Regarding the fact that the crime of homicide was not taken over by the federal jurisdiction, expert witness Castresana Fernández indicated that “[a]ccording to the integral investigation principle, the PGR [Office of the Attorney General of the Republic] should have investigated the Cotton Field disappearances and murders.”389 357. The Tribunal observes that, although domestic legislation establishes the possibility that federal authorities can consider crimes of ordinary jurisdiction when they are related to federal crimes,390 that did not happen in this case.391 However, the representatives did not argue why this runs counter to the obligation to guarantee effective access to justice. In particular, it is unclear whether this is a faculty or and obligation and how it affected the investigation. The fact that the representatives did not provide sufficient clarification prevents the Court from making a ruling on this allegation. 358. In relation to the results of the investigation into organ-trafficking, the Court observes that, in 2007, some measures taken in that investigation were indeed 387 Cf. report of the Office of the Attorney General of the Republic, “Homicidios de Mujeres en Ciudad Juárez, Chihuahua” (case file of attachments to the application, volume II, appendix 5, folios 184 to 216), and Office of the Special Prosecutor for the Investigation of the Murders of Women in the Municipality of Juárez, Chihuahua, Tercer Informe, January 2005 (case file of attachments to the answer to the application, volume X, attachment 81, folio 3362). 388 Cf.
