title: [Fratricide and Schizophrenia].
abstract: BACKGROUND
  Fratricide is the killing of one's own bother. It's a type of homicide rarely seen on psychiatric practice. This is still a theme which is poorly studied, and not well understood by the scientific literature.
  
  
  OBJECTIVE
  To report a case of a men, with paranoid schizophrenia that murdered his own bother and had a psychiatric forensic evaluation to establish his penal responsibility.
  
  
  METHODS
  A psychiatric interview was carried out and the psychiatric diagnosis was established based on the interview and analysis of forensic and medical records, using the DSM-IV-TR criteria. Literature review was held about the theme.
  
  
  RESULTS
  The examinee was considered not guilty by reason of insanity, due to the presence of a mental disorder that affected her entire understanding and volition of the practiced act.
  
  
  CONCLUSIONS
  The study of such cases may illustrate and identify motivating factors related to homicidal behavior in individuals with severe mental disorders.
