I just wanted to point out that the sum of all of the Zodiacs Ciphers equals 793, almost the exact same number of pages of the first edition of Mein Kampf which was 790. Could he have been wanting to give an almost exact number of characters of all the codes to equal Mein Kampf perhaps?
Z408 + Z340 + Z13 + Z32 = 793
Keep in mind this is the first German edition I am talking about not the English version.
The first German edition of Mein Kampf was published in two volumes in 1925 and 1926. The first volume had 354 pages and the second volume had 436 pages, making a total of 790 pages. However, it’s worth noting that there were later editions of Mein Kampf in German that were expanded and revised by Hitler, which had different page counts.
Why would I put this also in the category of Forensic Psychology? I believe it shows an extreme OCD with numbers for the Zodiac Killer (whom I think is Joseph Paul Franklin).
