Zodiex
A source-first reference to the Zodiac Killer case — the attacks, the victims, the ciphers, the letters, the suspects, and the decades of claims built around them.
Zodiex does not tell you who the Zodiac was. It tells you who said what, when, and where it came from — and labels how solid each claim is — so you can follow the evidence yourself. How to read Zodiex →
Start here
- The Case — orientation: what the Zodiac case is, the confirmed series of attacks, and how this archive is organized.
- The Zodiac — the unidentified offender who named himself in letters to the press — the ciphers, the correspondence, and why the identity remains open.
- The Attacks — the confirmed series of attacks (December 1968–October 1969), the people targeted, and the disputed additional claims.
Then by category:
- Ciphers — the cryptograms, solved and unsolved (Z408, Z340, Z13, Z32).
- Letters & communications — every letter and card attributed to the Zodiac.
- Victims — the confirmed and claimed victims, treated factually.
- Named figures & suspects — who was named, by whom, and on what basis.
- Timeline — the attacks and the key dates.
- Sources — the archive every page is built from.
How reliable is any of this?
Every page, and many individual claims, carry a status label — corroborated, attributed, disputed, theory, speculation, debunked, or unverified — so you can tell a corroborated record from a rumor at a glance. When sources disagree, Zodiex shows the disagreement rather than picking a winner. What Zodiex is and isn’t is spelled out on the About page.
A living, auto-compiled archive
Zodiex is built by reading a large source archive and compiling it into these pages. It is not fact-checked before publishing, and it improves through correction over time. If you can document an error, the About page explains how to flag it.
A companion database of Solano County residents lives at db.zodiex.org, linked from individual figure pages where a matching record exists.
