Contact gunshot wound causing bursting diastatic fractures. Gunshot wounds are their own special subcategory of forensics called Forensic Ballistics. Analyzing a gunshot wound is an art, and there are whole textbooks on the topic. What can we tell about this gunshot wound? First of all the weapon was pressed directly against the skull when fired. The further away the weapon was, the more circular the entrance wound would be. That’s not the entrance wound that we see here, that’s the exit wound given the ‘pucker’ and amount of skull blasted out. We know this is close range because it generated force enough to blow the skull apart at the suture lines (a diastatic skull fracture). We can tell that it was a rifle of some sort because a contact gunshot wound with a shotgun would not leave much skull left, and a handgun can’t generate that kind of force. Since we know it’s a rifle we can further infer it was a contact gunshot because the further away the rifle was the smaller the holes would be (they’re paradoxically smaller than the bullet at further range).
