Abstract
Penetration of the cranium typically results in secondary projectile formation (bone and primary projectile fragments); the formation of a temporary cavity and resulting increase in internal pressure which is enhanced by the confined space of the cranium and the stiff bones of the skull [1]. This enhanced internal pressure can result in fractures of the base of the cranium, because it is not as strong as other parts of the skull [1]. Radial fractures are typical at the impact point, but concentric fractures can also occur connecting the radial cracks due to flexing of the skull. This through-thickness failure is commonly referred to as cratering [2–4]. Bullet wipe is reported on the scalp in forensic case studies e.g. [2–4]. The fact that bullet wipe can be identified to specific bullets is of interest forensically when investigating attempted murder or murder incidents in civilian and military scenarios [5].
