42 Chihuahua] further noted a lack of technical and scientific capacity and training at that time for members of the judicial police. Officials of the State of Chihuahua indicated that the deficiencies were such that, in 25 cases dating back to the first years of the killings, the “files” consisted of little more than bags containing sets of bones, which provided virtually no basis to pursue further investigation.135 148. The Court observes that even when the details provided by the State authorities to the IACHR Rapporteur and indicated above were limited to the investigations and proceedings conducted up until 1998, the State itself acknowledged before the Tribunal that there had been irregularities up until 2004 (supra para. 20), although it did not describe them. 149. Several reports published between 1999 and 2005 agree that the investigations and proceedings concerning the murders of women in Ciudad Juárez have been plagued by irregularities and deficiencies136 and that these crimes have remained in impunity.137 According to the Special Prosecutor’s Office, “it should be emphasized that the impunity of the unsolved cases occurred, principally, from 1993 to 2003, owing to serious omissions made by the personnel of the Office of the Attorney General of the state [of Chihuahua].” It added that, over that period, the “state governments failed to enact public policies to endow the state Attorney General’s Office with the infrastructure, working methods and specialized personnel that would have allowed it to conduct the investigations into the killings of women with an acceptable level of reliability.”138 150. According to the evidence provided, the irregularities in the investigations and the proceedings included delays in starting investigations,139 slowness of the investigations or absence of activity in the case files,140 negligence and irregularities in gathering evidence and conducting examinations, and in the identification of victims,141 135 IACHR, The Situation of the Rights of Women in Ciudad Juárez, supra note 64, folio 1750 (citing the letter of the Secretary of Government of Chihuahua to the Special Rapporteur of February 11, 2002). 136 Cf.
