The Zodiac 340 Cipher Solved
Tuesday,
May 22, 2007
On or about November 8, 1969, the Zodiac submitted what
would become known as his “340” cipher, aptly named because the
cipher has 340 variables.

The Zodiac repeatedly referred to the play
“Mikado” in writings that the serial killer made to police and the
newspapers. The Zodiac also created his work so that it appeared to be derived
from “radians”, as Gareth Penn was the first to point out in 1981
with his Zodiac radian theory work.
To give you an idea of how radians are used with a map,
you must first have a protractor.

You can see that as the degrees on the protractor are
applied to a map and its magnetic north, you can ascertain locations on the map
(grid locations) that are as accurate as one meter.
But as I mentioned above, the Zodiac was also very
interested in the “Mikado” play, a Japanese-orientated comedy.

In the “Mikado” there is one specific prop in
the play that could be used to derive “radians”.

The image above represents Japanese folding hand fans. The
Japanese folding hand fans are usually painted and have artwork on both sides.
They can fold up into a solid object to protect them and for ease of carry.

Notice too how the Japanese folding hand fan looks
like a protractor that can accurately measure radians.

The Zodiac wanted to point the police and the newspapers
towards Japanese culture for some as of yet unknown reason. The Zodiac found
the play “Mikado” to be the venue to give the police clues. So what
I did in regards to the Zodiac’s “340” cipher was to treat it
with the same clues that the serial killer gave in his other communications to
police. By folding the “340” cipher in the same way as a Japanese
folding hand fan, this is what appeared.

Conclusion
The Zodiac was possibly giving police directions to
a victim location known as “Red Loop 12”.
The “Red Loop” could also be an
indicator of a red piece of jewelry that one of the victims may have been
wearing, or possibly it means that the Zodiac tied a “Red Loop”
around the ankles of one his victims and is telling police that he was
responsible for the crime.
The Zodiac’s “340” cipher was
mailed by the Zodiac to the San Francisco Chronicle on November 8, 1969. A
short time afterwards, a young woman named Leona Roberts was kidnapped from her
apartment and found dead in Tiburon near the Bird Sanctuary Lagoon. Autopsy
reports indicate that Leona Roberts was held captive for at least eleven days,
and evidence also indicated that she was bound at the wrists with some type of
nylon material. The Zodiac’s “340” cipher may have been
created by the Zodiac before the kidnapping and murder of Leona Roberts took
place, indicating that the Zodiac had planned her kidnapping well in advance of
the crime and also planned her murder.
“Red Loop 12” is also the name of one

What
victim location was the Zodiac referring to in the 340 cipher solution? Was it Leona Roberts?
