THE IDENTITY IN THE HALLOWEEN CARD?

9/11/2025

 
PictureHALLOWEEN CARD OUTER
Recently I have released two articles examining the solution of "Me⊕" in the April 20th 1970 letter mailed by the Zodiac Killer, having been formulated by a combination of Edgar Allan Poe, the 340 cipher and the three 8's in the Z13 code. Further hints towards this solution have possibly been unearthed in the 13-Hole postcard mailed a few months later in October, and Exorcist letter mailed on January 29th 1974 in which the Zodiac Killer changed his signature to "Me" for the first time.

​The April 20th 1970 letter tempted us with an identity stating "My name is", the 13-Hole postcard contained 13 holes punched into the fabric of its design and the phrase "Fk I'm crackproof", the March 13th 1971 "Los Angeles" continued the theme by proclaiming 
"This is the Zodiac speaking Like I have allways said, I am crack proof", with the Exorcist letter again suggesting an identity might be hidden in its contents by the introduction of "Yours truley", followed by the Tit-Willow verse from "The Mikado". But crucially, the January 29th 1974 letter added the signature of "Me", that can be replicated using the three 8's from the Z13 code by employing a cipher wheel described by Edgar Allan Poe. But there is one communication nestled in between these other mailings, that also tempted us with a name, much like the April 20th 1970 letter. The Halloween card, mailed on October 27th 1970, began with "I feel it in my bones you ache to know my name. And so I'll clue you in".

If the Halloween card was going to give us the answer of "Me" proposed in the Z13 code, you would expect to find this word embedded in its design. Not only was the word "Me" curiously obvious in the Halloween card inner, it was present twice. The Zodiac Killer was clearly employing the eye in the knothole of the tree as himself, by surrounding the knothole with the ominous threat of "Peek-a-boo you are doomed".

But there is one striking feature about the writing on the tree. After the phrase "PEEK-A-BOO" the Zodiac Killer positions the word "DOOMED", such that the "ME" lines up with "PEEK-A-BOO" to create "PEEK-A-BOO, ME". It is definitely noticeable that the word "ME" is visibly larger and bolder than the rest of the writing, as if to place emphasis on this pronoun. The skeleton's left arm is also affixed to the Halloween card in such a manner that it separates the word "GAME" to spell "ME". The word "BOO" is written on the card inner at a 45 degree angle so that it too lines up with the word "ME".

The word "BOO" around the knothole and the word "BOO" to the immediate left of the skeleton, are both positioned in alignment with the word "ME". Was the Zodiac Killer giving us the answer of "ME" to "I feel it in my bones you ache to know my name. And so I'll clue you in"? Thereby replicating the answer of "ME" possibly given by the proposed solution to the Z13 code on April 20th 1970. And the signature of "Me" he would ultimately deliver on January 29th 1974 to the San Francisco Chronicle.    FURTHER READING:
