Assassino em série e a desconstrução de uma personalidade indesejável: um estudo de caso

Abstract

The present study analyzes the case of an individual who committed, over a period of sixteen months, twelve serial homicides that victimized boys aged eight to thirteen years, practicing libidinous acts with four bodies, and hiding all corpses. The crimes were committed between 2002 and 2004, in the state of Rio Grande do Sul – Brazil, with intervals ranging from days to months. The individual was diagnosed with antisocial personality disorder of the serial killer subtype and paraphilic disorders of pedophilia and necrophilia. The antisocial disorder has a propensity to criminal behavior, and the conduct is usually associated with the commission of illicit acts. The paraphilic disorder, on the other hand, does not present a criminal tendency itself, but the action of paraphilias may involve illegal practices. Therefore, these disorders are commonly associated with the serial killer, conceptualized as the agent who commits three or more murders on separate occasions, involving similar aspects of modus operandi, ritual and signature. The association of these conditions offers great challenges to science, given the ineffectiveness of the criminal and clinical treatments currently available, in addition to the difficulty of identifying these agents during the police investigation. For this reason, the present study seeks to broaden this discussion, highlighting the need to develop a legal approach specifically directed to criminals diagnosed with such disorders and the importance of adopting investigative techniques that facilitate their identification and capture.
