Before beginning an autopsy, we must gather as much information as possible to help us interpret any marks we discover on the body. It is good to know who the victim was and in what setting the corpse was found. Witnesses should be questioned and experts consulted.
A well conducted autopsy gives almost as much information as talking to the victim. We can learn when death occurred, its circumstances, and what happened to the body afterwards. We may also learn about the murderer, any objects used in the murder and the manner of their use.
A corpse cut with a scalpel is like an open book. Whoever examines the details and carefully tests every hypothesis will understand it.
