Les liens entre le statut parental et les infanticides des enfants de douze ans et moins
Infanticide is considered as being an important part of infantile mortality. In this study, infanticide is studied according to the parental status (biological parent versus non biological parent), method of death and differential rates of suicide. The first hypothesis proposed that there should be an over-representation of the non biological parents in the homicide cases with the children of less than twelve years and this in look of the population rates. The second hypothesis proposed that the murders of the biological parents should clothe a more final character (weapon usage to fire, poisoning) that the homicides of the non biological parents that should be principally characterized by bad treatments. Other hypotheses are examined according to the rates of suicide and of the sex of the aggressor. The present study is based on the cases of homicides of child under the age of twelve on the territory of the Quebec from 1990 to 2007 (N = 182). The results support partially the hypothesis 1 and confirm the hypothesis 2.  In this direction, the results of this study come to support the evolutionist hypotheses that principally are based on the theory of the parental investment. Implications of the obtained results are discussed.
