The Zodiac Killer – Putting the Case Together
Tuesday,
April 17, 2007
There
have always been questions about the authenticity of Zodiac evidence compiled
by police since the beginning of the Zodiac serial killer case. The Zodiac case
dealt with numerous bits and pieces of evidence that the serial killer sent in
to police and newspapers. Since the evidence could not be linked together in
any tangible way that made sense to investigators, there was no conclusive way
to determine if all the evidence was produced by the Zodiac or if other
individuals were involved in the evidence stream.
I am
pleased to announce that I have tied in three separate major pieces of the
Zodiac evidence stream and will prove that the evidence was authored by one
sole individual, the Zodiac himself. It was a long journey getting to this
point, and I hope that readers of this site enjoy the work that I have produced
about the Zodiac case.
To put it
all together, we must first look at the Zodiac evidence timeline and the
evidence that will be used in this briefing. Then I will explain how all of the
evidence is tied together with one document that the Zodiac used as part of his
serial killing operation. This information can be used freely by law
enforcement working on the Zodiac case and for training purposes. Please quote

April 20, 1970
The
Zodiac mailed in the “My Name Is” cipher with a bomb diagram.

The
solution to the “My Name Is”
cipher is:
A Train H Blood M
The
linked page above that contains the cipher solution that I completed theorized
that the Zodiac used numeric values for the “H” and the
“M” in the cipher solution. Using the alphabet, the numeric values
for “H” and “M” are 8 and 13 respectively. The 813 was
then theorized to be a chapter and verse of the 66th Book of the
Holy Bible, the Book of Revelations.
From
Revelations Chapter 8, Verse 13:
“Then
I looked, and I heard an eagle flying in mid-heaven, saying with a loud voice,
"Woe! woe! woe! to those who dwell on the earth, because of the remaining
blasts of the trumpet of the three angels who are about to sound!”
This clue
tied in with the fact that the Zodiac used a Phillips 66 map which he mailed a
segment to police. 66 = the 66th book of the Holy Bible and the 813
from the “My Name Is” cipher solution = Chapter 8, Verse 13 in the
Book of Revelations.
However,
the “H” and the “M” in the “My Name Is”
cipher solution also have another, stunning meaning. We will get to that in a
moment. First, we will look at the bomb diagram again that the Zodiac included
with his “My Name Is” cipher.

At the
top of the bomb diagram, the Zodiac writes, “Sun light in early
morning”. This is a clue given by the Zodiac to orientate the map to the
east, because the sun rises in the east. Using Google Earth, I punched in
“

See it?
If not, let’s look closer together and do a comparison.

The Google
Earth image is perfectly aligned to the East, just as the Zodiac’s bomb
diagram is aligned per his instructions. But since the Zodiac wasn’t a
bomber, what was his purpose in selecting this location? It is a rest area
which is now known as the “Hungry Hunter” restaurant off the
interstate. The Zodiac was submitting a diagram telling police that he was
hunting in locations such as rest areas off the highway.
June 26, 1970
The
Zodiac mailed in his “Button Letter” with a segment of a
“Phillips 66” map, the type of map that you could purchase at
Phillips 66 gas stations that unfold. This is the image of the map that the
Zodiac mailed in.

In order
to work a case such as the Zodiac case, it is important to work with the same
materials that the serial killer did in order to see if any of the clues that
the Zodiac left for investigators could be tied in with what the Zodiac had
available to him. In this case, it did tie in. With the help of a friend from
October 27, 1970
The
Zodiac mailed in his Halloween Card.

Front Back
Now that
all of the evidence is compiled, it is time to put it all together. The
Halloween card that Zodiac mailed in to police gives really good clues.
Let’s examine them.
The first
clue on the front of the card is the word “paradice”. Using the
Zodiac’s Phillip’s 66 map, the complete and unaltered map, there is
a “

On the
back of the Zodiac’s Halloween card, there are images of eyes in the left
column of the card in the same location as the word “paradice” on
the front of the card. Using a scan of the QQ code Phillip’s 66 map that
the Zodiac used which was printed in 1969, the evidence becomes crystal clear
as to the clue that the Zodiac gives to police. The left side of the
Phillip’s 66 map has one remarkable feature:

The
original Phillips 66 map that the Zodiac used doesn’t have an
“I” in its left-hand column on the map. It has an A thru H, and
then a J thru Q! This is a clue by the Zodiac to use the Phillips 66 map with
the information that he submitted to the police and the newspapers in
association with the Halloween card clue using the “eyes”.
Even more
spectacular is this:

I
couldn’t fit the entire image in my scanner, but this is what I did here.
I ran an azimuth from the “H” in the left column center of mass to
the “M” in the right column of the Phillips 66 map. Remember that
the solution to the “My Name is” cipher was “A Train H Blood
M”? The H + M were used by the Zodiac as map coordinates as well as a
Holy Bible reference to the Book of Revelations.
I then
ran an azimuth from magnetic north on the Phillips 66 map to get a resection
anchor point. That 10 digit grid coordinate falls perfectly with
“Paradise Cay”, a small docking point in Tiburon for boats. You can
see how the magnetic north azimuth for the map goes straight through the
Phillips 66 trademark on the azimuth. This was the clue that the Zodiac gave on
the front of the Halloween card with the word “paradice”. The
complex azimuths that the Zodiac created here is indicative of prior military
experience.
Now for
the last sequence. Let’s review the back of the Halloween card again.

The
skeleton in the Halloween card has both his hands raised as if he is hanging
from an invisible line. The skeleton’s feet are waving to the left (the
skeleton’s left) as if being pushed by the wind like a sail. The skeleton
itself is really a two dimensional image placed over the top of what was
written by the Zodiac on the Halloween card. This is an important clue. Using
scissors, I removed the skeleton from a copy of the Halloween card and then
applied the skeleton to the Phillip’s 66 map using the grid coordinates
that the Zodiac provided police with his “H” and “M”
clue from the “My Name Is” cipher solution.
This is
what appeared:

Now, from
the X axis “0” point, the skeleton is shifted to the right 1.2
miles, using the Phillips 66 map legend. Why? The Zodiac tells us to with the
clue on the Halloween card indicating wind direction.

= 8-12 knots (9-14 mph)
= 13-17 knots (15-20 mph)
Now,
using the wind equations we get:
15 – 20 mph
- 9 – 14 mph
------------------
= 6 – 6 mph
=
6 mph
The
answer to the Zodiac’s wind equation puzzle is 6 mph to the South East on
the X axis. This would move the skeleton approximately 1.2 miles to the South East
along the X axis which would put the sine in the skeleton’s feet (the
triangular astrological symbol) directly center of mass of the Naval Net Depot
on the map. If you look at the back side of the Halloween card, the skeleton’s
left hand is resting on webbing. This is another clue in a long list of clues
that the Zodiac’s final destination for the skeleton was the Naval Net
Depot on the Phillip’s 66 map.
The
Zodiac appears to be giving clues to some important feature in the 3100 + block
of Paradise Drive in Tiburon, or possibly a work location at the Naval Net
Depot or some other facility. The Zodiac used the Halloween card and his other
mailings as a puzzle as to his direct identity, so this location in Tiburon has
to be connected to the Zodiac in some way.
Even more
importantly, this proves that the “My Name Is” cipher, the “Button
Letter” cipher and bomb diagram, and the Halloween card were all produced
by the same individual and sent in to the police and the newspapers. It is
simply stunning that the “My Name Is” cipher gives the clues H + M
which form a perfect X axis in Tiburon to Paradise Cay. From there, the Halloween
card which was mailed to police months after the “My Name Is” cipher,
not only integrates the cipher solution, but uses it as a topographical map
clue that the Zodiac submitted to police as a series of puzzles.
The
evidence above was clearly written by the Zodiac and submitted to police by the
Zodiac Killer. How the sine location in Tiburon connects to the Zodiac case
must be on record somewhere in the investigation, or at a minimum will allow
police to reopen the Zodiac case to find out why the Zodiac felt this location
was so important.
