Case Overview

A multi-victim investigation covering four widely recognized Zodiac-linked attacks in Northern California from 1968 to 1969. Five people were killed and two survived.

The name "Zodiac Killer" refers to an unidentified individual associated with a series of attacks and communications in Northern California in the late 1960s. Four incidents between December 1968 and October 1969 are widely treated as the core of the historical case. Across these incidents, five people were killed and two survived.

The people killed in these attacks were David Faraday, Betty Lou Jensen, Darlene Ferrin, Cecelia Shepard, and Paul Stine. Michael Mageau and Bryan Hartnell survived attacks. The victims must be remembered as individuals, not treated only as elements of a puzzle.

Letters and cryptograms sent to newspapers helped bring public attention to the case. The FBI's public archive includes correspondence, investigative requests, and historical documents. No internet theory about the killer's identity should be presented as an official finding. Claims of additional victims or attacks must be clearly distinguished from the established core series.
