If the 18 characters at the bottom of the 408 character cryptogram are set aside and considered as a separate cryptogram with a new set of substitutions, and if that cryptogram were to be considered the signature of the Zodiac, revealing his name as promised, Joe Karadanis (aka Joey Paradice) fits astonishingly well, one must admit:

E  B /E  O R /I  E  T  E  M  E  T  H H / P  I  T  I

↓  ↓   ↓  ↓  ↓  ↓  ↓  ↓  ↓  ↓   ↓  ↓  ↓  ↓   ↓  ↓   ↓  ↓

B Y /J  O  E /K  A  R  A  D  A  N  I  S /T  U  R  K

Substitutions:

Sym.

I =       K, U E =      A, B, J T =      R, N,

M =     D H =      I, S B =      Y

O =      O R =      E
