[Some medico-psychological perspectives on sexual homicides. Three cases]

While sexual murders are widely reported in the media, there are almost no reports on these major crimes in the French medico-psychological literature. After a brief historical and legal overview, the author discusses the forensic definition of sexual homicides, parent-to-child transmission of sexual violence, the distinction between paraphilic and non-paraphilic sexual offenders, criminal affects, and the classification of aggressors in violent homicides. He confirms that particularly violent murderers may be divided into two psychiatric and behavioral categories. Next, the six main causes of sexual homicide are presented together with three clinical observations of such cases: 1) one with homosexual connotations; 2) another through hate for women; 3) and a third where rage was not specifically directed. Finally, the author concludes that there should be systematic criminologic research in France into sexual murders.
