Finding the Zodiac Killer delves into the symbols left behind in the killer’s letters, ultimately confirming the identity of a man behind one of the nation’s top unsolved mysteries.


The Description

Publication Date: October 14, 2023

In the late 1960s and early 1970s, a serial killer, who called himself the ZODIAC, terrorized Northern California with cold-blooded murders and a series of taunting ciphers and letters. His first set of three ciphers, considered at the time to be one, were sent to three newspapers in 1969. They were cracked by a couple within a week. On July 11, 2021, David Daniel read, where the Zodiac had stated in a letter, that the three ciphers contained his identity, but the couple and the authorities claimed that it wasn’t there. David believed that the authorities had said the ciphers didn’t reveal the Zodiac’s identity for one reason—they couldn’t find it. He knew it was there and he knew that he would find it. He looked at the first of the three ciphers—the one that the Zodiac had sent to the Vallejo Times Herald. Within three to seven seconds, he knew he had solved the nation’s most notorious unsolved murder case. David studied the cipher further and looked at other ciphers that the killer had sent. One by one he cracked the ciphers and completely solved another. Within two minutes he had absolutely confirmed the secret identity of the ZODIAC killer multiple times. Law enforcement and cryptographers have been searching for his identity for over 50 years. Finally, the search is over. He has been found!

ExcerptPDF-imgThe Review

The most famous unsolved murder case in America allegedly has been solved within three to seven seconds.

David Daniel outlines how he deciphered the identity of the nation’s most notorious serial killer in Finding the Zodiac Killer.

Rather than a traditionally written book written in paragraph form, Daniel uses chunks of information, photos of the victims, and reproductions of the messages. From there, he recreates the many letters sent to the media by the Zodiac Killer, along with others signed by a concerned citizen attributed to him. He shows readers the ciphers and clues, pointing out the killer’s identity over and over.

A more focused approach would have been highly effective in consolidating information in a cohesive manner.

The author’s purpose is to show readers how the ciphers sent by the killer do, indeed, reveal his identity. The author claims that within two minutes, he had absolutely confirmed the secret identity multiple times, which finally provides an answer to a mystery over 50 years old.

While I haven’t seen a response from law enforcement regarding Daniel’s research, he makes excellent points in dissecting the cipher. Whether it will hold up to the scrutiny of others remains to be seen.

About The Author

Let me tell you a little about myself. In the 1970s, I predicted that the serial killer called the Hillside Strangler were two people (not one) and that they were stepbrothers or step cousins. I was right. I predicted that another serial killer, the Grim Sleeper, lived near 81st and Western in Los Angeles. When they found him, he lived three houses down from the corner of 81st and Western. 

When the TV series The Mentalist came out in 2008, I deciphered codes, unscrambled anagrams, and solved multiple clues and I knew the secret identity of Red John—the fictitious serial killer on the series—after the first two episodes. I have written a book about my discoveries called The Mentalist Code and the Search for Red John.

Now I have cracked the ciphers and clues sent by the real serial killer—The Zodiac—who terrorized Northern California in the late 1960s and early 1970s. Cryptologists, law enforcement and other have been seeking his identity for over 50 years. 

My book—The Code: The Secret Code Hidden in the English Language—which details my amazing discovery of a secret code hidden in the English language is too shocking to believe—will be coming out within weeks.

My name is Amy W., and I am a book addict. I will never forget the day I came home from junior high school to find my mom waiting for me with one of the Harlequin novels from my stash. As she was gearing up for the "you shouldn't be reading this" lecture, I told her the characters get married in the end. I'm just glad she didn't find the Bertrice Small book hidden in my closet. I have diverse reading tastes, evident by the wide array of genres on my Kindle. As I made the transition to an e-reader, I found myself worrying that something could happen to it. As a result, I am now the proud owner of four Kindles -- all different kinds, but plenty of back-ups! "Fifty Shades of Grey" gets high marks on my favorites list -- not for character development or dialogue (definitely not!), but because it blazed new ground for those of us who believe provocative fiction is more than just an explicit cover. Sylvia Day, Lexie Blake, and Kristin Hannah are some of my favorite authors. Speaking of diverse tastes, I also enjoy Dean Koontz, Iris Johansen, and J.A. Konrath. I’m always ready to discover new-to-me authors, especially when I toss in a palate cleanser that is much different than what I would normally read. Give me something with a well-defined storyline, add some suspense (or spice), and I am a happy reader. Give me a happily ever after, and I am downright giddy.
