Was Zodiac Ever Solved? The Chilling Truth Revealed

The Basics: Who Was the Zodiac Killer?

Okay, let’s rewind for a second. If you’re not familiar (or you only know the movie with Jake Gyllenhaal), the Zodiac Killer was an unidentified serial killer who terrorized Northern California in the late 1960s and early 1970s. He claimed responsibility for multiple murders, sent creepy handwritten letters to newspapers, and taunted police with coded messages — some of which took decades to crack. Literally decades.

I remember the first time I read about it — I was maybe 14, late at night, rabbit-holing through Wikipedia like a psycho. I swear, I didn't sleep properly for two nights. Something about the way he wrote “this is the Zodiac speaking” gave me actual chills.

So... Was the Zodiac Case Ever Solved?

Officially? No. But that’s not the full story.

Short answer: no, it’s still unsolved. The San Francisco Police Department and the FBI never officially identified or charged anyone. The case is technically still open in some counties — though it's considered cold.

That being said... the internet (of course) has thoughts. Actually, a lot of thoughts.

Theories, suspects, and a whole lotta dead ends

Over the years, tons of suspects have been floated:

• Arthur Leigh Allen — probably the most famous one. His name comes up in every doc. He had the right watch, the right typewriter, even creepy behavior. But no hard evidence ever tied him to the crimes.

• Gary Francis Poste — In 2021, a group called The Case Breakers said it was him. They even had photos with scars they claimed matched the Zodiac’s sketch. But law enforcement didn’t back it up, so… maybe?

• Tons of other names I won’t list here because, well, most turned out to be baseless. Some were just straight-up weirdos who liked the attention.

Honestly, I used to think Allen had to be the guy. But the more you dig, the more you see how shaky everything is. It’s like one of those puzzles where every piece kinda fits… but only if you squint really hard.

The Cryptic Ciphers: Solved, Partially

Some were cracked — but not all

One of the craziest parts of this case is the Zodiac ciphers. He sent four main coded messages (the Z408, Z340, Z13, and Z32). For years, only the first one (Z408) was solved — by a high school teacher and his wife, by the way. Not even the FBI.

Then in 2020 (yes, 2020!), a team of codebreakers from around the world finally cracked the Z340 cipher. I remember watching the YouTube video breakdown and thinking, “Holy crap, this is like national treasure meets horror.”

The message didn’t give a name, but it was classic Zodiac — creepy, mocking, and vague. He wrote stuff like:

“I hope you are having lots of fun in trying to catch me.”

(What a jerk.)

The other ciphers? Still unsolved. Some experts even think they’re just gibberish.

What Makes the Zodiac Case So Frustrating?

No DNA. No clear motive. Just chaos.

Look, part of why this case haunts people is how messy and incomplete everything feels. The guy wore weird disguises, changed methods, left clues but also red herrings. It’s like he wanted to be caught but also didn’t. Maddening.

There was even a moment when they thought they had DNA… from a stamp on a Zodiac letter. But nope. Either degraded or not usable. I read about that in a Reddit thread at 2AM, and I swear, the collective disappointment of that community could’ve powered a small town.

It keeps popping up, even decades later

This thing refuses to die. Books, movies, endless YouTube videos. Even my friend Jess, who isn’t into true crime at all, messaged me last year like “Wait, didn’t they solve Zodiac??”
Nope. Just another theory making headlines.

Could the Zodiac Ever Really Be Solved?

Honestly? I’m torn.

Part of me hopes one day, some breakthrough tech — DNA, AI, whatever — gives us an answer. Another part of me thinks… maybe it’s better as a mystery. Some cases become too big, too mythic. Like if you knew who Banksy was, would it be as cool? (Okay, maybe that’s a stretch, but still.)

If I had to bet, I’d say: we might get close, but a clear, official answer? Probably not. But hey, that won’t stop people from trying. And honestly, part of me likes that — the chase, the obsession, the shared frustration. It’s weirdly human.

So yeah, was Zodiac ever solved? Nope.
But is the story over? Not even close.
