-92their functions, and also that civil society should participate through nongovernmental organizations that have been engaged in this search or that are specialized in working with young disappeared persons, such as the Asociación ProBúsqueda. c) Creation of a search web page 189. This Court considers that a database should be established by creating a web page for tracing the disappeared children. The database should be set up with the given names and surnames, possible physical characteristics and any other existing information about the Serrano Cruz sisters and their next of kin. 190. The web page should include the addresses and telephone numbers of several State institutions (such as, the Attorney General’s Office, the Ombudsman’s Office, the National Civil Police, the Immigration Department, the Ministry of Foreign Affairs, Embassies and Consulates of El Salvador, the Chalatenango Trial Court, and State institutions for the protection of children, youth and the family), the national tracing commission (supra paras. 183 to 188), and non-governmental organizations such as Pro-Búsqueda, so that, if the Serrano Cruz sisters are alive and contact this page, they and anyone who has information about them can find the next of kin, and the pertinent governmental or non-governmental institutions, or forward information on Ernestina and Erlinda and their whereabouts. 191. In this regard, the Court considers it essential that, using this web page, the State should adopt the necessary measures to coordinate national links with the different governmental and non-governmental authorities and institutions mentioned above, and also international links with the web pages of other States, national institutions or associations, and international organizations engaged in trying to trace children and young people who have disappeared, in order to promote, participate and collaborate in the establishment and development of an international search network.60 The State shall comply with the foregoing within six months of notification of this judgment. d) Creation of a genetic information system 192. The Court emphasizes the importance of using science to identify the people who disappeared and their next of kin, in order to determine the relationships and establish contacts between those who are seeking someone who disappeared and those who became separated from their families involuntarily and who are seeking them. In this regard, the Court has noted that Father Juan Cortina Garaígorta stated in the public hearing before the Court that the investigative techniques used by ProBúsqueda “to be able to find the children involved in the conflict,” included the “elaboration […] of a DNA genetic code […].” In this regard, the priest stated that “more than 1,500 [to] 1,800 DNA tests [were] being carried out.” However, the Courts notes that the State has not collaborated in developing this investigative technique; rather Pro-Búsqueda has received help from abroad. 60 In this regard, there are web pages aimed at tracing disappeared persons in which El Salvador could participate. They include the one developed by the project coordinated and financed by the Swedish Save the Children within the framework of the Regional Program for Latin American and the Caribbean. The address of this project’s site is as follows: www.latinoamericanosdesaparecidos.org.
