The Zodiac 340 Cipher Solved?

Using this Word Search Gadget for the infamous, unsolved Zodiac 340 Cipher, I was able to find numerous names and words connected to the Zodiac killings, clearly written repeatedly across the cipher with one letter in each adjoining column or row. They include the names of all the known victims:


Bates
BettyLou
David
Michael
Darlene
Bryan
Cecilia


Diablo
Radian
SFPD

Is the Zodiac's name included in there somewhere?... I think so.

Ten names and words are found scrambled in the "code" and there are only four points of overlap in the letters (circled). Two of those are the N and E in Darlene and Stine, which you might expect if someone is inserting the two names.

This image of the cipher shows words from the Zodiac Halloween Card. They are written multiple times but here I show the four words with sixteen letters and with five intersections. GUN, KNIFE, ROPE, FIRE. I don't know if that means it could have been written first or written after the names of the victims and the other words.

I tested the solution and it looks good so far.When I tried to search the top 5 most popular boys names 6 letters or longer, I found only one Jayden.
I couldn't find

Jackson
Elijah (except with I replacing L which doesn't work for me)
Benjamin
Alexander

But 7 Zodiac victims names are all there (8 if you include Bates).

I found one particular suspect's name clearly written out, first last and middle names in the same six columns.
It's the same method used for finding "Earl Van Best Junior" that some find questionable, including the author of the zodiackillerscyphers page, but it's doesn't mean the method is incorrect. How could all these words and names show up in a unsolvable and presumably nonsense code?

A group of codebreakers have managed to crack the infamous 340 cipher used by the Zodiac Killer over 50 years ago.

I doubt the code was double encoded. Not impossible I guess.

The Ripper was definitely a "spectacle killer" like the Zodiac but wrote in poetic code or with poetic license.

Then again, we already know that the 408 was double encoded with at least one name -- the name of the Zodiac Killer.

And the 340 uses the letter J only 4 times by my count (once backward) and one fits with Betty Joe, the only victim with the letter J. 

The content of the decoded message was about slaves so double encoding a list of the names of his supposed slaves-to-be.
