Autopsy following death by homicide in 644 cases.

The objectives of this study are to determine the cause of death and based on the wounds, to analyze the different epidemiological variables on homicide in Dakar. Included were all homicides cases where an autopsy was performed and these results recorded in the autopsy register. The data collected in our work included, identity, sex, age, place of crime (location), the cause of death (the causative agent and the anatomical region injured) and the mechanism of death (the pathophysiological phenomenon causing death). On average 56 cases of homicide a year are reported, ranging from 44 cases in 2005 to 80 cases in 1999. Extrapolated to the population of Dakar this corresponds to 1.9 homicides per 100,000 inhabitants. Victims aged over 55 years represented only 4.03% of all victims. 6.52% of cases were infanticide. The crimes mainly took place in the suburbs of Dakar (51.42% of cases). Hand held weapons were used in 578 cases (89.7%) followed by firearms in 44 cases (6.8%). The study of the age of the victims has some interesting points. The homicide of elderly people in Senegal was relatively low in contrast to what is found in a developed country. The youthfulness of our population also explains the large number of homicide victims between 21 and 25. Infanticide is a particular problem in Senegal. In our study, 50.6% of homicides were found in the suburbs of Dakar followed by the peripheral area which accounted for 29.3% of homicides. The incidence of homicide can be directly correlated with the level of economic development. This frequency is much higher where incomes are low and particularly affect young males. The study of this phenomenon should lead to better prevention. The victim-type in Dakar is a young man, aged 20-25 years, killed by an instrument with an injury to the skull, neck, heart or main arteries, causing bleeding and death.
