Z 408 Zodiac Killer Cipher Solution

Cipher Part 1
Like the other parts of the cipher, its first part includes inaccuracies and errors, possibly made by the Zodiac Killer himself when he transcribed the cipher symbols from draft to final version. Obviously, the cipher symbol   at F13  should read , and  the cipher symbol  at G9 should read  . The cause of the cipher errors may have been the thickness of the Zodiac Killer’s writing tool.

Cipher Part 2
Like the other parts of the cipher, also its second part includes inaccuracies and errors, possibly made by the Zodiac Killer himself when he transcribed the cipher symbols from draft to final version. Obviously, the cipher symbol   at I11 should read , the cipher symbol  at P10 should read , and the cipher symbol at  at N12 should be  . The cause of the cipher errors may have been the thickness of the Zodiac Killer’s writing tool. Additionally, the Zodiac Killer obviously forgot to include the letter “I” in the word ‘EXPERIENCE”. These errors certainly, and assumingly unintentionally, increased the difficulty level of the Z-408 cipher.

Like the other parts of the cipher, also its third part includes inaccuracies and errors, possibly made by the Zodiac Killer himself when he transcribed the cipher symbols from draft to final version. Obviously, the cipher symbol   at U6 should read  . The cause of the cipher errors may have been the thickness of the Zodiac Killer’s writing tool.
