The Number 3 and……again more 8. Please Rush to Reddit!!
Previously I have mentioned the importance of numbers to the Zodiac Killer and it is my belief that he did have a pretty bad case of Obsessive Compulsive Disorder (OCD). More evidence of this is the prominence of the number 3 along with a a sense of symmetry in his coded messages. I will show some examples.
First, the 408 was split into three parts.
Z340 was comprised of three sections.
It doesn’t stop there either.
Mysteriously, there is an absence of some symbols in the transposed/untransposed versions of the 340.
See below:


Notice how in each version the 340 is “split” into three sections.
The lines that have a lack of the symbols listed above each are 8 lines.
The 408 was split into three sections of 8 lines each.
Again we see 8 lines where these symbols are absent in each version of the 340.
I believe this was not really meant for the public to “figure” out in any way but more along the lines of someone who believes in the necessity of having certain numbers in having “good luck” as most OCD people feel to give it more chance of having success.
On another note, I have noticed that the transposed version includes the backward “L’s” or what I think are actually “J’s”.
Again, I don’t think this type of behavior was made for people to figure out but more just for him and him alone. People who think like this believe that they must have these type of things for this to “work”, for “good luck” or else something bad will happen to them.
Additionally if we go back to the patterns the pivot patterns mentioned in Dave Oranchaks Lets Crack Zodiac episode 9 “Odds and Ends” he mentions the mystery of the unexplained patterns backward L’s/J’s.

Notice how each pattern is made of 7 letters each, but if you add the dot which translates to “V” each pattern consists of 8 characters, not 7.
Additionally the 340 starts and ends with an “H”. Either an encrypted H symbol and the cross at the end breaks to a plaintext “H”. So the 340 starts and ends with the 8th letter of the alphabet, making 88 there.
88 in the middle, with 8 lines in the transposed and untransposed versions of the 340 are missing symbols. Making
88 for the patterns.
88 for the missing symbols in the middle of the 340.
Starts and ends with an 8 making yet another “88”.
I take it by now you all know who I think did it!
