13 28 that some disappeared children were victims of illegal trafficking. Finally, at September 2010, the 29 Search Association had located 48 cases of children who had perished. Lastly, “in the cases of both adoptions through a legal procedure and appropriation of children, there was a practice of altering the minor’s identity; many were registered as sons and daughters; in other words, without the need to alter the records; in other cases the names or surnames were 30 changed together with the child’s age.” 69. In response to the need to look for the children who had disappeared, Executive Decree 45, issued on October 5, 2004, created the Inter-Institutional Commission to Trace Missing Children in El Salvador (hereinafter the “Tracing Commission”). Several international and national agencies have mentioned the need to create a tracing mechanism. They include the UN Committee on the Rights of the 31 Child , the Human Rights Ombudsman of El Salvador, and the petitioner in this case, Asociación Pro Búsqueda. As this Commission failed to produce any specific results, culminating its mandate without results, on January 15, 2010, a new National Commission for the Search of Disappeared Children was 32 established; it official started up its operations on March 14, 2011. 70. Next, the IACHR will establish the facts that have been proven separately with respect to each particular case, since the alleged disappearances occurred in different circumstances. In addition, even though some of the proceedings have certain similarities and even involve children of different family groups, the Commission considers it pertinent to establish in each case the domestic proceedings that were carried out, before the Office of the Human Rights Ombudsperson and other state authorities.
