One day, someone discovered that a bomb drawing created by the Zodiac Killer was an overlay mask for a section of a map he mailed to the police. He discovered that this bomb schematic marked locations, as well as a section of highway with a string of bombs. This was how it all started. Building on this find, many other things began coming to light. Not knowing what to do, he then created a site for all of this in a simple place to make it easy for anyone to see.
