More on the Pivot Patterns Backward L/J’s = JV In the Z340 Zodiac Killer

Pivot patterns were intentional and indicate the initials “JV” were important to the Zodiac Killer among more examples of the number 8 and numbers in planning the Z340.

Previously I had mentioned that the patters in the Z340 indicate an intention to create these patterns.

A quick recap of some of the previous things I had written about in regards to these patterns. It is my belief that these patterns consist of 8 symbols not the seven as outlined in the videos by the channel “Lets Crack Zodiac”. A very good channel by the way, a lot of credit goes to this channel for putting out this info on some of the mysteries of the 340.

1.) Patterns consist of 8 characters, not 7

2.). Mysterious absence of characters from transposed and untransposed versions of the 340 occur on 8 lines in the middle of the 340.

3.). 340/18 = 18.8888

4.) Transposition scheme is 18 characters apart. You can say every 19th letter, but there is 18 characters between each correct spacing between each correct character for most of the 340.

5.) 340 starts and ends with an encrypted H symbol and last symbol decryptes to “H”. 88?

6.) We find more evidence of the numbers 8 and 3 being significant even in the 408. That is a list as well, but for now we’ll just leave it at that.

7.) 340 starts with “H” and “+” so it starts with an 88 in some ways, you can interpret that as starting with an 88 as well.

For those reasons I believe that the patterns are intentional. Added to this is that one of the “mistakes” turns out to complete the second pattern.

Mistakes in the Z340

When Zodiac writes because “E Now Have”. that mistake, the “E” becomes the last part completing the 2nd pivot pattern.

I counted 8 mistakes in spelling unless I somehow missed one.

I excluded two spellings of Paradice, one is misspelled but I think there is a reason for that also.

He does mention Paradice 3 times. Paradice = 8

Moving on to some other observations on the 340:

Adding further credence to the idea that what he was hinting at was “JV” in the patterns was the observation by Dave Oranchak and I assume his team that there is evidence of character cycling although weak, but take a look at the letters that are cycled.

Notice at the end the “JVM”.

JAMESVAUGHN?

Another note on the patterns. They are not hard to do. Actually pretty easy if you are careful, this was a very carefully constructed cipher but with multiple meanings within it.

Answer to the bonus question from last post:

The number 81. So, the top of the first pivot patter is an “R” that is at the top of the first pivot pattern.

When untransposed and unencrypted it is the 81st letter of the 340 that then turns out to be the “top” or start of the pivot patterns.

If you count 8 across and 8 down, you come to the top of the pivot pattern and turns out this is the 81st character when the 340 is properly broken and decrypted into the message.

Below is when transcribed properly that “R” then decryptes to “O” see below:

** Note If you use cipher explorer and hover your mouse over the characters it has the “O” as character 80. This is because cipher explorer starts with Zero, not 1. You must add a plus one to the count to see it correctly.
