The unsolved crimes of California’s Zodiac killer continue to frighten and fascinate decades after Bay Area newspapers received the first chilling letters from the deranged pen pal. A memorable quote from the classic western, The Man Who Shot Liberty Valance, reads, “When the legend becomes fact, print the legend.” While the legend of the Zodiac killer becomes fact, the truth behind the headlines is online at ZodiacKillerFacts.com.
