The Zodiac Killer: The Mystery Behind America's Most Feared Serial Killer If not for the ominous shadow of Jack the Ripper, the case of the Zodiac Killer would perhaps be the greatest mystery the world has ever known. The Zodiac Killer was the self-given name to a murderer who took responsibility for the deaths of at least five people in the San Francisco area of California throughout the 1960s and 1970s. Over the decades, the case has become synonymous with mystery and injustice. The Zodiac Killer's murders were brutal, bizarre and without remorse. He began by targeting young couples in lovers' lanes and executing them with close-range gunshots. His murders then progressed, indicating a highly-unstable frame of mind yet one intelligent enough to evade capture. He would go on to taunt the police and the media with strange ciphers and messages which would take significant time to decode - some of which remain untranslated to this day. Despite extensive searching, analysing and profiling, no conclusive evidence of the Zodiac Killer's identity has ever been put forward. Of course, many theories exist, some of which appear to answer all of the questions one would have regarded the identity of a notorious serial killer. However, none are concrete enough to serve as solid confirmation of who he really was. This book looks at all the evidence, and tries to piece together the clues that point to the true identity of this murderer.
