AbstractThe suicidal infliction of two gunshot wounds to the head represents a critical issue for medicolegal investigation. In principle, simultaneous infliction with two firearms or third parties' involvement, i.e. two consecutive gunshots, have to be considered. We report for the first time on a case of suicidal infliction of two simultaneous gunshots to the head (oral, temporal) with Action 4 expanding ammunition. A male had robbed two service guns and committed suicide thereafter under the influence of high-dose alcohol and cocaine. Interestingly, Action 4 ammunition had been used, leading to an uncommon gunshot wound morphology and extensive backspatter. At the scene, these findings caused confusion; moreover, the number of gunshot wounds was unclear, until autopsy revealed two gunshot wounds to the head, which had obviously been inflicted simultaneously. Expanding ammunition like QD-PEP and Action 4, used by several German federal state police forces, can cause an atypical gunshot wound morphology, most probably due to its peculiar deformation behaviour. Investigators should be careful when interpreting gunshot wound morphology at the scene after usage of such expanding ammunition. With regard to reconstruction in cases of two gunshot wounds to the head and two guns at the scene, two simultaneous gunshots should be taken into consideration.
