I have one little fact of mine to add to this article.
The map from the link above shows the place where the Zodiac Killer mailed the Los Angeles letter and where Kathleen John’s abduction took place. It also points to where other victims were found that are unsolved murders still to this day. These cases have similar characteristics to the known Zodiac Killer crimes. The red dot is where my POI lived from 1972 to 2009. I just wanted to show how close in proximity he was to these crimes.
