Comparison of wound patterns in homicide by sharp and blunt force

A comparison of patterns of injuries between sharp force and blunt force homicide was performed. Male predominance was seen in both types of homicides. Most of the victims of sharp force were between 21 and 40 years and those of blunt force between 31 and 40 years. There was no difference in the incidence of victims below 20 years age, but blunt force was almost five times more than sharp force in victims of age above 60 years. Thorax was the commonest site to be involved in sharp force in contrast to head in blunt force. Hand and forearm were the commonest sites of defence injuries in sharp and blunt force homicides, respectively. The majority of the blunt force victims had lesions in only one region in contrast to involvement of 2–4 regions in sharp force. The majority of the victims were killed by acquaintances in blunt force, but criminals always prefer sharp force to kill their victims. Single weapon was more commonly used in blunt force as compared to sharp force. Knife and wooden/iron rods were the weapons of choice in their respective categories. Most of the victims of sharp force were killed outdoor in contrast to victim's own domicile in blunt force.
