Section 2: The Clues
 |
| The Zodiac Killer Enigma |
First, let’s look at the clues Zodiac left behind.
He didn’t make it easy.
He mixed real clues with misdirection, making it harder to see what actually mattered.
One of the first examples comes from the letters sent to Paul Avery.
Zodiac spelled his name “Averly.”
Not a typo.
A play on the word “overlay.”
Notice the “L” in Paul.
It underlines the “AV” in Avery, making it read like “lay.”
In the image below, it looks like a “K” is placed over an “L.”
I can’t say exactly what that means, but it may be another reference to an overlay.
Now look at the 340 cipher.
Zodiac marked out a “K”, then made a correction by placing a reversed “K” above it.
You’ll see this later.
Notice something important.
He didn’t capitalize “Averly,” but he did capitalize “Paul.”
That suggests he wasn’t using “Averly” as a name.
Read it another way:
“Hey Paul… overlay.”
This is what’s called a play on words.
A name is used, but it’s meant to sound like something else.
A simple example:
On The Simpsons, Homer once used the name “Avery Mann,”
which sounds like “Every Man.”
Same idea.
It’s a name pun.
And once you see it, it’s hard to miss.
If you want it even tighter (more punch, less explanation), use this version:
He capitalized Paul, but not Averly.
That matters.
It reads like:
“Hey Paul… overlay.”
That’s a play on words.
A name that sounds like something else.
Same idea as “Avery Mann” sounding like “Every Man.”
“Sorry, your ass is draggin.”
This is referred to as the “Dragon Card.”
I wonder why that was sent… haha.
In this section, I used overlay-style examples to show how these kinds of wordplays can be constructed.
The example below uses a similar play on words for a name.
When you look at it, doesn’t it resemble “Averly”?
I’m not saying it is the same thing.
I’m showing how a pattern like this can be created using overlays and name manipulation.
Forensic Analysis: The Coupling Logic
Subject: Interaction between the Z340 Cipher and the Mt. Diablo Map. Evidence Source: Primary Correspondence ("The map coupled with this code...")
The Strategic "Linkage"
The statement "the map coupled with this code will tell you where the bomb is set" is not a suggestion; it is a mechanical instruction. By using the term "coupled," the author confirms a geometric dependency.
Definition of Coupling: To connect, join, or synchronize two distinct parts to function as a single unit.
The Misdirection: The secondary code sent alongside was an intentional "smoke screen" designed to draw focus away from the primary geometric coupling required to solve the map coordinates.
Geometric Truth
When you "couple" the 340 solution to the map, you aren't just looking at two pictures; you are aligning two sets of data into one coordinate system. This is the "linkage of distinct concepts" defined in your high-resolution dictionary plates.
Component Identification: The 340/Map Linkage
Technical Determination: Within the body of evidence provided by the author, the Z340 Cipher is the only data set possessing the complexity and geometric structure capable of being "coupled" with the map to produce precise coordinates.
The Halloween Card Variable: The Halloween card sent to Paul Avery serves as a critical secondary reference. While it contains thematic misdirection, it also reinforces the "4-quadrant" logic and the use of specific symbols that align with the 340's grid-based structure.
The skeleton sticker on the card is a physical "overlay." This isn't just decoration; the "V" symbol is a mechanical marker. When you locate this same symbol within the 340 Cipher, you'll find it embedded in a cluster of dice—confirming you are on the right track.
Pay close attention to the "dots": notice the four dots surrounding the "V" symbol. Also, identify the "Z" marker. On the 340 grid, this symbol is paired specifically with a "Z" beside it, acting as a geometric anchor for the next layer of the solution.
Investigation Update (2026): Looking back at my initial findings, the "Paradice" misspelling remains one of the most significant verbal keys. While the official spelling is "Paradise," the Zodiac’s version is a phonetic instruction: "Pair-a-dice."
In common speech, we often use the relaxed "o" or "a" sound—like "barrel-o-monkey" or "pair-a-dice." This isn't just a typo; it’s a mechanical wordplay. By phonetically spelling it this way, the author was providing a direct hint to pay attention to the dots and the grid found within the 340 Cipher.
Historical Precedent: > This phonetic play has real-world roots. For example, in the 1930s, there was a casino in Las Vegas actually named the "Pair-O-Dice," illustrating that this specific wordplay has been used to link "Paradise" with gaming and dots for decades. Once you recognize this linguistic "overlay," the connection to the dice clusters in the 340 becomes undeniable.
Investigation Update (2026): While the back of the Halloween card has long been a subject of debate, my research confirms it acts as a direct instruction to locate a "pair of dice." This phonetic clue leads us directly to the Z340 Cipher, where the "V" symbol from the card is physically embedded within a cluster of dice.
The Quadrant Discovery: > It is now widely accepted in the research community that the Z340 is divided into four quadrants (a theory notably explored by researchers like
The Zodiac cross symbol itself is more than just a signature; it is a direct geometric hint. It represents a cross "OVERLAID" onto a circle that has been divided into four quadrants.
This structural clue points toward the use of radians—a specific mathematical method for measuring circles—which I have successfully located within the grid of the Z340 code. By recognizing the symbol as an instruction for an overlay, the relationship between the cipher and the map coordinates becomes clear.
What Is a Radian? (Simple Explanation)
A radian is just another way to measure an angle—like degrees.
Most people know a circle has 360 degrees.
But in math, we sometimes use radians because they are more natural and easier to work with.
Think of It Like This
Imagine a circle, like a pizza.
Now:
- Take the radius (the distance from the center to the edge)
- Lay that length along the edge of the circle
The angle you get at the center from that length is 1 radian
👉 So in simple terms:
A radian is the angle made when the edge of a circle is the same length as its radius
Even Simpler Version Explantion
- A circle can be measured in degrees or radians
- 1 radian is a “natural slice” of a circle
- There are about 6.28 radians in a full circle
Quick Facts
- Full circle = 360 degrees = about 6.28 radians
- Half circle = 180 degrees = about 3.14 radians
- 1 radian ≈ 57.3 degrees
Why Do We Use Radians?
Radians make math easier in:
- Trigonometry
- Geometry
- Physics
- Engineering
They help formulas work more cleanly without extra steps.
Keywords (naturally built in for your blog)
This write-up already includes useful search terms like:
- what is a radian
- radian definition
- radians vs degrees
- angle measurement
- unit of angle
- circle geometry
- trigonometry basics
If you want to push it a little further for Google, you can add a section like:
Radians vs Degrees
Degrees divide a circle into 360 parts.
Radians measure angles based on the circle itself, which makes them more useful in advanced math.
What is a radian in simple terms?
A radian is a way to measure angles based on the size of a circle.
How many radians are in a circle?
About 6.28 radians (which is ).
Why are radians important?
They make math in trigonometry, physics, and engineering easier and more accurate.
This is a widely used version and is even shown on Wikipedia, so it’s not an obscure or unusual setup. It
also appears in popular media such as Assassin’s Creed.
This matters because the same structural elements used in a Pigpen key—the grid and the dots—are also
key features in the 340 code, as I will demonstrate later.
The Zodiac Cross: A Masonic Connection
I recommend reading up on this because the Masons call the "cross-hair" symbol—the one the Zodiac
made famous—the "Zodiac Cross."
The Masons called it the "Zodiac Cross" for reasons that have nothing to do with the Zodiac killer. In
fact, they used that name long before the Zodiac Killer was ever even thought about.
The Origin of the Symbol
Here is where the Zodiac got his symbol and an example of the original Zodiac Cross. It is also called a
Sun Wheel—which is a bit like a clock.
He did not take the name "Zodiac" because of a watch; the watch actually took its name from this
symbol. For those who might not know, there is a watch brand called "Zodiac" that uses this symbol,
and some people thought he stole his name from them. In reality, the Zodiac Cross is much, much
older than any watch.
The Stine Murder: A Coded Route?
The night Paul Stine was murdered, he picked up his attacker on Mason St. He then drove him to the
intersection of Washington and Cherry.
Everyone knows the story of George Washington cutting down the cherry tree, but many forget that
Washington was a famous Mason. His nickname was "The Spy Master" because of the codes and
secret messages he used during the Revolutionary War.
Mason Street itself holds many Masonic secrets. I am currently collecting more data on this for my
"Zodiac Killer and the Masons" post. Even in the Zodiac movie, you can see a building being
constructed not far from where the killer was picked up at the theater.
"Read Between the Lines"
Have you ever heard the phrase "Read between the lines"? It actually comes from George Washington
and his spy ring. They would write secret messages in invisible ink between the visible sentences of a
letter. That is the true origin of that phrase.
The Map and the "My Name Is" Cipher
The map that came with the code and the "My Name Is" cipher are connected. In both cases, you first
have to figure out the hint, then use the number of characters in each code to complete a "fill in the
blanks" puzzle. He even left hints to this.
The Math of the 13 Slaves
The phrasing "(on top of everything else)" in the image is a direct suggestion to use an overlay.
The word "paradice" points toward the 340 code because of the dice symbols found within it. When
you perform the map overlay, all 9 of the Zodiac symbols fall directly on highways. The odds of that
happening by accident are astronomical.
The author talks about the 13 slaves he has waiting for him in "par-a-dice." When all the overlays are
completed, they reveal exactly 13 dots on the map:
5 dots from one bus bomb overlay
2 dots from the second overlay
6 dots from the 340 dice symbols
Total: 13 dots
In the image below, he references the number 13 again, and there are exactly 13 holes/dots punched out
in the card. This confirms the count isn't a guess—it's the goal.
The Halloween Card: Visual Instructions
There are also 13 eyes on the Halloween card. This is important for a couple of reasons. The eyes
looking through the holes are hints telling us to overlay and to find the 13 dots on the map.
Even the spider web on the card is a hint to the Radians used on the 340 code. The eyes themselves
could be an overlay mask for something else—I have a few ideas on that, but they aren't posted yet.
The Hidden Symbol
The symbol on the card is hidden within the "Par-a-dice" section of the 340 code. The dots around the
"V" symbol on the card are a clue that the solution is all about the dots.
"Paradice" is a hint to a "pair of dice." When you draw the dice around the dots on the 340 code, lo
and behold, the "V" symbol appears exactly as it did on the card.
They called it “masking.”
This isn’t just something from the past either. Navy SEALs, Special Forces, and intelligence
operatives still use versions of these techniques today.
Think about it like this.
You are a soldier in a place like Vietnam or Afghanistan.
You have a map, but you do not want those marked locations falling into the wrong hands if you are
captured.
So what do you do?
You use something called an overlay mask.
Instead of marking the real map, you mark a separate document that looks harmless or meaningless
on its own, something like the 340 code.
If that document is captured, it does not reveal anything important.
That is the idea I am working with here.
I am looking for real, documented examples of this method so people can clearly see what I mean, not
just read about it in theory.
I will show one example from the Revolutionary War later in the section about the hidden message.
If you try to research this yourself, you will notice something.
There is not much information available online.
Most of what I have found comes from military manuals, handbooks, and older sources that I am
going through carefully.
And I will say this plainly.
Methods like this were used, and they are still used today.
If you really want to dig deeper, you will probably find more at a library than anywhere on the internet.
For now, I am sharing what I have while I continue to look for stronger material.
I will cite known examples, historical precedents, and similar codes or puzzle methods whenever I'
can.
Over time, I have already added quite a few.
Why This Matters
This is not just about codes.
It is about how information is hidden, protected, and understood under pressure.
Once you see it, you start noticing the same patterns everywhere.
