Homicídio seguido de suicídio: relato de caso / Homicide followed by suicide: case report

Objetivo: Examinar o fenômeno clínico de homicídio seguido de suicídio (HS) a partir de um caso no qual o desfecho de suicídio não ocorreu por motivos alheios à vontade e às ações do sujeito. Descrição do caso: Trata-se do caso de um homem que matou sua namorada por ciúmes, por ocasião do término do relacionamento entre ambos, tentando, a seguir, o suicídio. No presente artigo, é dada especial ênfase aos aspectos forenses do caso, avaliado para fins de determinação de responsabilidade penal e acompanhado no Instituto Psiquiátrico Forense Dr. Maurício Cardoso, Porto Alegre (RS). Comentários: Ressalta-se que, ao se modificar o desfecho de um caso típico de HS, por não ter se consumado o suicídio do homicida, dois aspectos assumem relevância: as consequências legais a serem enfrentadas pelo sujeito e o manejo do impacto psíquico no sobrevivente. Do ponto de vista da prevenção, o conhecimento do fenômeno HS e dos fatores descritos como associados a ele justificaria uma constante atenção ao tema por parte dos profissionais de saúde mental. O presente relato foi autorizado pelo paciente através de termo de consentimento livre e esclarecido.

Psychological autopsy and its limitation in application / 法医学杂志

The suicide were analyzed depending only on the death scene and cadaver features but not on the psychological autopsy (PA) that also enables the determination of the manner of death in China for a long time. There are significant differences between PA and the traditional risk assessment of suicide. The goals of PA are to find out the features of individuality, the patterns of behavior and the possible motives of suicide. The methods of PA involve investigating, collecting and analyzing all related information of the deceased. There are many limitations of PA in application mainly due to the lack of the standard procedures. Although an improved procedure has recently developed by Berman, many problems need to be solved before the actual application of PA in China.
