Suicide in adolescents is a problem that increasingly affects the population. According to the World Health Organization, it is estimated that suicide occurs every 4 seconds, and it is the second cause of death in adolescents, which has worsened in recent years. Once a suicide occurs it is important to understand the causes that lead to it. To be able to dictate once the suicide occurred, a psychological autopsy is performed, which seeks to understand the factors for which it was committed, taking into account the life that the victim was carrying, his personality, family relations and other data. The methods used are the observation of the evidence obtained, the interviews that are made to the different members of the family and the close friends of the victim, and from which the conclusions about the victim's decision are derived. The present case is a psychological autopsy performed on a 14-year-old adolescent whose cause of death was suffocation by hanging.
