Who do you think the Zodiac Killer actually is?

[bdsjr]

I am merely a reader/observer on this thread, I like to disclaim this because I do not know nearly all these details you all share! I only know surface info on Zodiac but love to follow and hear theories. So interesting and such great research you all do!

It's fascinating because it's like he's so many things:
- Could be military/cilivian (trade?) worker
- Interest in the theatre or possibly English Arts

IMHO it's much easier to make grammar mistakes if you aren't versed in punctuation/English Arts or if you are an "average joe" but he didn't do that - he knew his grammar and didn't make mistakes in that area. He chose to make mistakes (or play on words?) with spelling.

It's like it's backwards - a high percentage of people know to spell for the most part, I would think a lesser percentage know their proper punctuation and grammar. He made mistakes in something most wouldn't. Was this a red herring or he thought a game? JMO MOO

A game is my prediction. Our first clue was the word Christmas. He always spelled it Christmass or X-Mass. Who does that? Most first graders can spell Christmas. Was he telling us he was Catholic? You are very correct about his grammar and punctuation. He used colons and semi-colons, tons of commas. However, I don't think that means college as you get all of that K-12. My best guess is that he was self-educated after high school. Probably was a voracious reader from childhood and forward, but not always reading wholesome stuff. The true detective magazines and some of the comic book filth available back then come to mind. He would have been a huge consumer of the newspapers available at his local library.

One thing is very clear to me but not everyone thinks so: He was smart, not a genius but crafty. He spent a lot of time thinking about everything. He almost got caught in San Francisco but then again, if the officers had stopped him, they might be dead or he might be dead or both, but I doubt he would have allowed them to jump out on him without gunfire as capture would have meant the death penalty.

I'm also fairly convinced that as a child, he was neglected, bullied, disregarded, dismissed, rejected, and probably abused in some fashion. He would not have been popular at school or with girls. As he grew up, he was either invisible or viewed as a failure. Then you add psycho to the mix and you get a raging fire on the inside that he kept hidden. Killing and taunting was his way of getting revenge plus notoriety. I figure he walked around with a little skip in step knowing he was the real life boogey man but no one knew it. The reason he was not caught because he was the guy next door. No one suspected him and he kept a clean record.

The spelling mistakes make me think he may have been Dyslexic. If not then I think it was done on purpose to throw off investigators. Being Dyslexic might explain the cyphers. Making up an alphabet he can understand.

This is not the Zodiac speaking.

Id be curious to know if anyone over the years a colleague or acquaintance of the Zodiac reported to LE being familiar with the Zodiac's writings/cryptography. I suspect we will never know, but nonetheless it would be interesting to know. Strange that no one has seen his work before his killings. jmo

He may have disguised his writing somehow. He could not have disguised everything but maybe a few dedicated letters. Possibly in his job, he wrote mostly in block capitalized letters instead of lower case like he did in his taunts. Writing in lower case would provide natural camo for him if colleagues never saw his lower case printing. But yes, you'd think someone would have noticed something about his writing.

Note about his writing that took me a while to pick up on: he had excessive spacing between words, and exessive spacing between puntuation and letters. It is really prominent.

RSFB. Zodiac’s misspellings don’t read to me as signs of illiteracy but as strategy. He may have been deliberately obscuring his true educational level, muddying any linguistic profile that could tie him to a region, class, or schooling background. There’s also a mocking quality to his grammar, a kind of performative sloppiness, as if he were trolling the police while pretending not to care. That, in itself, suggests he understood how linguistic profiling works and was actively trying to sabotage it. JMO

The idea of 'performative sloppiness' mentioned by Sor Juana is fascinating. It suggests a high level of control over his public image. I've been analyzing his geographical 'comfort zone' for my blog, The Missing Pieces, and this linguistic sabotage fits perfectly with a suspect who knew exactly how to stay invisible. Great insights here!

Yep, he definitely was someone of high intelligence. He knew how to manipulate the narrative hence the deliberate sloppiness.

The Zodiac could have learned the techniques behind Z340 from self‑study (newspaper cryptograms, puzzle books) or from military/intelligence training - both are plausible; there’s no proof he had formal cryptography schooling, and the 1960s context makes military or amateur routes the likeliest. Newspaper cryptograms and syndicated puzzle columns were common in the 1950s–60s; a curious, persistent reader could learn substitution tricks and homophonic ideas from practice. Basic classical cryptography (substitution, transposition, simple enciphering) was taught in some military roles (signals, communications, intelligence). A veteran or ex‑service member could easily know how to design layered ciphers. Early Zodiac ciphers were solved by amateur enthusiasts, showing the community knowledge existed outside formal institutions. The problem is that thousands of discharged servicemen could have had cryptography skills; screening them all would be impossible and legally fraught without specific probable cause. Investigators therefore focus on people who match the case profile or who are tied to the inquiry by other evidence. JMO
