Alcohol and fatal penetration of the cranium by an airgun pellet—a case study from Poland

Abstract

BackgroundAirguns with the energy of ejected pellets below 17 J are not considered weapons in Poland, can be purchased without permission, and do not require registration. The mere possession of this kind of airgun does not entail any legal consequences, unless it is used for an unauthorized purpose. Sports and recreational shooting do not have to take place within shooting ranges. However, the improper use of this type of weapon can lead to serious injuries and death. In addition, the impact of high blood alcohol content on pain perception can lead to a lack of awareness of the gunshot.Case presentationA 36-year-old woman died a few hours after a head injury inflicted by a 5.50-mm caliber pellet fired from an air gun. The first pellet penetrated perpendicularly through the left temporal bone to the brain. The gunshot tract of this head wound was 6 cm long and ran horizontally and perpendicularly to the surface of the squamous part of the temporal bone. The tract ran through the skin of the skull, the left temporal muscle, and the squamous part of the temporal bone (where the bone was only 1.5 mm thick). The pellet then penetrated the cerebral dura mater, cerebral pia mater on the borderline of the left temporal and frontal lobes, and left lateral wall of the sphenoidal sinus. The victim did not complain of pain due to a high level of alcohol intoxication (0.35 blood alcohol content). The pellet from the second shot (on the foot) penetrated the right foot and was inflicted by the victim.ConclusionThe victim died not earlier than 3 h after being shot as a result of intracranial injuries that caused hemorrhage. The outcomes of this study indicated that high alcohol content resulted in reduced awareness of the victim and no apparent symptoms of developing intracranial injuries.
