About Zodiex
Zodiex is a research wiki about the Zodiac Killer case. It is an organized, interlinked map of a very large archive of source material — newspaper coverage, letters, documents, photographs, directories, books, and articles spanning the case from the late 1960s onward.
Please read the points below before relying on anything here.
This is an aggregation, not a verdict
The Zodiac case is defined by contradiction: hoaxes, retracted statements, conflicting press accounts, and decades of competing theories. Zodiex does not resolve those conflicts and does not claim its contents are true. What it offers instead is traceability and transparency — for every claim, you can see who made it, when, and where it came from.
It is compiled automatically
Zodiex is built by a language-model pipeline that reads the source archive and writes these pages. Because the archive is far too large to fact-check by hand before publishing, pages are not human-verified at publication. They are labeled by reliability at the time they are compiled, and corrected incrementally by human editors over time. You may encounter errors, including transcription errors from degraded scans. Treat Zodiex as a finding aid that points you to sources — not as a final authority.
How to read the reliability labels
Every page, and many individual statements, carry a status label. The label measures how much you should trust the statement as true — not whether it has a source (everything here does):
- corroborated — independently supported by more than one source, or backed by a strong primary or contemporaneous record (a dated article, a document, a physical letter) with nothing against it. The strongest category.
- attributed — asserted by a named party, recorded but not independently confirmed.
- disputed — sources disagree; the page lays out the competing positions.
- theory — a proposed explanation or hypothesis, offered as interpretation, not as fact.
- speculation — a bare possibility with little or no support.
- debunked — refuted by evidence or established consensus.
- unverified — surfaced from the archive but not yet assessed for reliability.
When you see a “Conflicting accounts” section, that is intentional. Zodiex preserves disagreements rather than smoothing them over.
On naming people
Zodiex records allegations; it does not make them. Where a page mentions that someone was named as a suspect or connected to the case, it is reporting that a named source said so, on a stated date — not asserting, in Zodiex’s own voice, that the person did anything. Nothing on this site should be read as an accusation by Zodiex against any individual.
On the victims
The victims of these crimes were real people. They are described here factually and with respect. If you are connected to the case personally and find something here that is wrong or hurtful, please use the corrections contact below.
Sources and copyright
Pages are original summaries and analysis with limited, attributed quotation. They are not republications of the underlying articles. Source pages cite and link to the original material. If you hold rights to material referenced here and have a concern, please get in touch.
Corrections
Zodiex improves through correction. If you can document an error — a wrong date, a misattribution, a debunked claim still labeled live — please reach out so an editor can update the page and its status. The change will be recorded in the page’s history.
The companion database
A structured database of Solano County residents lives at db.zodiex.org and is linked from person pages where a matching record exists. It is a separate, ongoing research tool.
