Case Reopened The Zodiac (1999– ) Online

This is a well-produced and factual overview of the infamous Zodiac murders case that took place during the late 60s and early 70s in the San Francisco Bay area of California.

This documentary combines recreations of the actual murders (very well done and not overly-sensationalized), along with relevant commentary from police officials, investigators and researchers.

The presentation sticks to the case's basic facts and paints a picture of an exceptionally cold-hearted killer whose propensity for violence was surpassed only by his incredible ability to play the media and to constantly adapt and evolve, a tactic that allowed him to stay several steps ahead of the police at all times.

Included are examples of the correspondence that the Zodiac killer sent to San Francisco Bay area newspapers and a discussion of how one of the killer's many cryptograms was finally deciphered.

Also included is a full discussion 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 which may explain the killer's bizarre motives for the crimes).

Highly recommended to anyone who has an interest in true crime and other sorts of unsolved mysteries.
