d) e) f) g) h) of the original beneficiaries and the alleged participation of military officials in those incidents, and to prevent the investigation from continuing; the representatives to the benefit of whom the broadening of these measures was requested have played "an active role not only in the context of the international processing of the provisional measures but have also continued to denounce the facts domestically," including by “filing briefs" before the different authorities and appearing before them in support and accompaniment of the members of the Alvarado family. As a consequence, they have "significant visibility" as a driving force behind the domestic investigations and the measures of protection before the bodies of the inter-American system; the threat that beneficiary José Ángel Alvarado Favela received on his cell phone took place after he appeared on January 28, 2011, at the Office of the Attorney General of the Republic, accompanied by his representatives and proposed beneficiaries Luz Esthela Castro and Gabino Gómez; both relatives and representatives participate in making the allegations and demanding justice. The latter accompany and provide backup for the actions of the relatives; at least one of the representatives who has participated in those activities beneficiary Emilia González Tercero - has been a direct victim of acts of harassment and intimidation, "strengthening the earlier indications that the risk extends to the representatives," and there are contextual elements that "together with the earlier elements," allow for the presumption of a situation of risk to the lives and personal integrity of the representatives. In particular, it indicated that, according to the United Nations Office of the High Commissioner of Human Rights, Chihuahua is in first place nationally with regard to complaints of attacks on human rights defenders. In this regard, it indicated that the attacks are various in nature and include "an intense climate of threats toward and harassment of human rights defenders who carry out their activities in the region." In this sense, it highlighted that in many cases these threats have culminated "in the disappearance and/or murder of [human rights] defenders, many of who were actively participating in publicly denouncing abuses of military forces in the state of Chihuahua." 9.
