The Zodiac Killer held San Francisco in a grip of terror in the 1960’s largely due to the letters and ciphers he sent the newspapers and police. Greg and Vanessa dig into the meaning of the mysterious messages, and try to figure out how a killer who mailed the authorities clues was never caught. They also take a look at the phenomena of false confessions.
With Greg Polcyn & Vanessa Richardson
