Crime scene

Determining which wound is the entrance wound and which is the exit wound is an important step in determining what happened at a crime scene. Generally, entrance wounds are smaller than exit wounds, because the skin is somewhat elastic, and it stretches when a bullet enters the body. Therefore, the size of the entry wound will be smaller than the bullet. Exit wounds are generally larger, because as the bullet moves through the body, it may collect and carry body tissue and bone with it.
