The Zodiac’s true motives remain unknown, but the study of his crimes reveals his signature. While some murderers may vary their methods of operation, a killer’s choices, actions, and words reflect his needs– even when he attempts to deceive and even when he does not realize that he is doing so. In this sense, the killer’s crimes will reveal his psychological fingerprint.
