30 Significant differences are observed in connection with mourning processes in cases of natural death as compared to deaths resulting from external violence. When death is natural, mourning goes through its natural stages and is finally resolved through resignation and resumption of daily life relatively soon. In the case of forced disappearance, daily normality is hardly ever recovered, as mourning remains frozen in one of its stages, linked to rage and non-acceptance of the outcome. There are also feelings of guilt of the survivor together with the impossibility of an adequate closure of the process, for which reason those feelings are a recurrent source of grief and anguish. The death of a child under conditions of external violence is one of the worst “stressors” that a human being can experience. The traumatic effect on the siblings takes place in two ways: due to the effects of grief and guilt, and the alteration of family dynamics as a whole, caused by the parents’ grief, as they are fixed in their memory of the missing child. The emotional effects of such a trauma can worsen mental or physical illness. In these cases, both the victims and next of kin have shown various types of physical diseases and symptoms in a greater proportion than would be expected for the general population. In the cases studied, the families were significantly affected in the allocation of intra-family roles and in the general dynamics of their members. Emotional pain due to the circumstances of the traumatic events (lack of information and denial by the bodies responsible, wandering among assistance centers, waiting at the morgue, etc.) created very intense ambivalent feelings. In the case of death or disappearance of the male figure (father, brother, son who was the household provider) they lost their economic status and even minimum subsistence conditions and support for future projects to improve the situation of the family. For survivors with permanent disabilities, the facts also involve loss of jobs, of spouses, and of personal independence, giving rise to a “situation of a dependent burden.” In connection with the families of the victims who do not know the whereabouts of the latter, it is indispensable to establish the whereabouts, and it would be very important for reparation measures to allow them, when this has not yet been done, to identify the remains of their beloved ones with certainty, in some cases, and in others to be able to bury them in an appropriate manner. This will improve the process of overcoming symptoms of depression through adequate development of mourning. Psychological treatment of the victims and their next of kin is necessary to overcome traumatic episodes, with the assistance of one or more mental health professionals (psychiatrist and psychologist). The cost of treatment depends on the time in therapy, which varies depending on the event and the patient’s pre-morbid functional level. Estimated time is one year, with weekly sessions at an approximate cost of US$30 to US$40 (thirty to forty United States dollars) per hour of treatment, that is, an average of US$1,500.00 (one thousand five hundred United States dollars) per patient per year. The fact that the Court is hearing the case has allowed the victims and their next of kin to have hope regarding the real possibility of justice being served, and it has given them trust in the effectiveness of international bodies.
