The Asociación Pro-Búsqueda for Missing Children (APB) is a non-profit organization that was born from the struggle of mothers, fathers and relatives to find their missing children during the Salvadoran civil war and that, in accompaniment of Father Jon Cortina began their tireless search. In this sense, Pro-Búsqueda promotes the investigation of cases of forced disappearance of minors during the civil war to establish their whereabouts, to know the truth of the facts and to be able to compensate for the damage that the victims suffered as a result of these serious violations of their rights.

The genetic research work and the processes of individual and collective support for victims and their families are some of the pillars of the work carried out by the organization. In the same way, Pro-Búsqueda seeks to influence Salvadoran society and International Organizations through its work and the development of activities related to historical memory, including in its work the new generations of youth defenders of human rights.
