ZODIAC KILLER

An independent investigative archive documenting evidence, cipher communications, witness statements, law enforcement files, media reports, and unresolved questions surrounding one of America's most infamous unsolved serial killer cases.

CASE STATUS: UNSOLVED

Case Overview

Between the late 1960s and early 1970s, a serial killer calling himself "Zodiac" terrorized Northern California while taunting law enforcement and newspapers through coded letters, cryptograms, and chilling public messages.

Despite decades of investigation, multiple suspects, and national media attention, the true identity of the Zodiac Killer has never been conclusively proven.

What If The Story Didn't End In California?

What if the Zodiac Killer did not disappear — but simply moved on?

What if unsolved crimes across America, forgotten newspaper articles, unidentified letters, or overlooked evidence contain clues waiting to be rediscovered?

Could fragments of the truth still exist inside old police archives, family collections, small-town newspapers, or forgotten witness accounts?

This archive explores evidence, timelines, historical records, and public information in an effort to organize the facts and preserve the mystery.
