In the case of Velásquez Rodríguez the Court confirmed the existence of “the right to inform the relatives of the fate of the victims and, if they were killed, the location of their 192 remains.” In this type of cases, it is considered that the relatives of the disappeared victims are victims of the phenomena of forced disappearance, by which they are entitled to have the facts investigated and the responsible 193 prosecuted and punished.
