[Heterogeneity of expert psychiatric conclusions. Study of 101 authors of voluntary homicides]. / Hétérogénéité des conclusions des expertises psychiatriques. Etude chez 101 auteurs d'homicides volontaires.

OBJECTIVES: Specify the prevalence of various mental pathologies observed in authors of voluntary homicides and assess the interest of the psychiatric expertise of these persons. METHODS: The conclusions of the psychiatric expertises of 101 authors of voluntary homicide; condemned (94.20%) or declared irresponsible because of mental or personality disorders (5.80%), in the Court of Appeal of Bordeaux, over a period of 10 years (1989-1999) were analyzed. RESULTS: Several elements were underlined, among which the multiplicity of the diagnoses made by the expert psychiatrists and the large proportion of these criminals suffering from mental pathologies (81.60%), which contrasted with the low percentage of such criminals declared irresponsible (5.80%) or suggesting they might be dangerous (7.80%). DISCUSSION: The use of a standardized classification of mental diseases would provide the members of the jury and the magistrates with a clearer picture of the mental status of criminals. This is essential to avoid that more than 80% of the latter are quoted as exhibiting a mental pathology when the experts present their conclusions.
