The 340 Cipher sent to the SF Chronicle

I state, I did not construct these solutions , I developed a code from the My Name Is cipher added to the 408 code key which led to more and more keys to the solution , there are 4 tweaks to it every division ( 4 or 5  lines) in the code key . To start with the H E R (1st three letters of the 340 became (zodiac killer symbol) I M ) then I saw a name coming after that. I have the scratch paper or long addition sort of ,of how I came up with the code key.  I am confident I would pass a lie detector test on this ,as I said.

note on line 9 and 10 , 3 letters are missing, done on purpose, I think you will see why.
the dot before damit possible a G for god (I think)

I am posting this on the Day of  49th anniversary of the Napa Attack

The last line of the 408 that was unsolved.... decoded

I give up trying to sell the cipher solutions, I will post the solutions to the other 3 ciphers the My Name is....the message to zodiac and the 340 ciphers. 

do not copy the images for repost , it is my intellectual property ...post the link instead if you wish to share
