Abstract
IntroductionConfessions in criminal cases range between 42 and 57%, all crimes considered. However, there is no data specifically on confessions regarding intrafamilial homicides, despite the fact that this subtype of homicide accounts for 30–40% of all homicides. ObjectiveThe purpose of the present research aims to establish the links between the sociodemographic characteristics of the perpetrators of intrafamilial murder, and their behavior and interaction with the criminal justice system after that they committed the crime (e.g., self-denunciation and confession). MethodAll cases of domestic homicide over a period of eleven years and judged in a single court of assize were analyzed (N=44). Data regarding the type of homicide (conjugal, parricide, filicide, familicide), the sociodemographic profile of the perpetrator (sex, age, family situation, occupation, educational level) and their behaviour pre-, during- and post- the homicide were collected and analyzed. ResultsThe common intrafamilial murderer is a 36years old man belonging to a disadvantaged socio-professional group, mostly without judicial antecedent. Moreover, confession rate is above 98% (including 41% spontaneous denunciations by the perpetrators themselves). Discussion and conclusionThis research supports earlier work on the profiles of family crime perpetrators. However, perpetrators of intrafamilial homicides confess more often than perpetrators of all other types of homicide. The results are discussed in terms of cognitive and emotional mechanisms. Suggestions for the use of such insights by investigative services are proposed.
