Abstract
A case of missile group identification by comparative examination using the image superposition method is presented. Identification was carried out using a skeletonized body vault exit gunshot fracture. The exit gunshot buttonhole fracture shape and dimensions reflected the bullet caliber and its flank profile. The entrance injury located on the anterior arch of the first cervical vertebra and the basilar part of the occipital bone, in this case, had no identification significance.
