16. Regarding the domestic investigations, the Court reiterates that the State has a special obligation to ensure the rights of persons in a situation of risk and must expedite the investigations required to clarify the facts, followed by the consequences established by the pertinent laws.5 However, the analysis of the effectiveness of these investigations and procedures regarding the facts that gave rise to the provisional measures corresponds to the analysis of the merits of the case.6 c) Information on the situation of risk of the beneficiaries 17. In their briefs of July 8, August 7 and 29, September 7 and November 20, 2011, and November 7, 2012, the representatives denounced the persistence and increase in the risk to the detriment of the beneficiaries of the measures based on the following circumstances: a) The time that has elapsed without the provisional measures being implemented and the erosion of the State’s interest in this case; b) The fresh acts of harassment against the representatives of the beneficiaries, because the State invited members of the military to participate in the meeting of June 3, 2011, in response to which the representatives requested “the withdrawal of the members of the military, because the matter that resulted in the provisional measures is a case of enforced disappearance in which it has been indicated that the Army is presumably responsible”; c) On June 5, 2011, at around 8 p.m., Federal Police agents burst into the office of the Paso del Norte Human Rights Center in Ciudad Juárez and, “without a warrant and without any justification, the police searched the office, destroying padlocks on doors with hammers and breaking windows”; d) On July 4, 2011, at around 2 p.m., beneficiary Jaime Alvarado Herrera arrived at a friend’s house near the Terranova Division in Ciudad Juárez where he was arrested together with three other people and taken to the Aldama Police Station; they were released after his father, Jose Ángel Alvarado Favela, who is also a beneficiary of these measures, came to the station.
