Photo montage depicting aspects of the infamous Zodiac murders case that took place during the late 60s and early 70s in the San Francisco Bay area of California.

I have set this to the music of "Scorpio's Theme," a track composed by Lalo Schifrin for the Zodiac-inspired movie "Dirty Harry."

Shown are images of the correspondence and cryptograms that the Zodiac killer sent to San Francisco Bay area newspapers, as well as the front covers of various detective magazines that featured the case.

Also included are examples of what is known among researchers as "The Radian Theory," a discovery that is perhaps one of the most intriguing aspects of the entire case and one that may explain the killer's bizarre motives for the crimes.

Through observation of the letters and codes the killer sent to area newspapers, many characteristics of Zodiac have been noted: he quoted directly from Gilbert and Sullivan’s light opera, "The Mikado," from the Beatles animated movie, "The Yellow Submarine" (1968) and possibly from "The Most Dangerous Game," a short story (and 1932 film) about a mad Count who grows tired of hunting animals and begins to stalk human prey.
