I am happy to endorse the Radians and Inches journal, a publication devoted to examining the Zodiac killer. In the 1960's a serial killer who went by the name, Zodiac terrorized Northern Californians. For years, he eluded the police and taunted their investigators. The Zodiac even created his own cipher codes. Mark Hewitt examines the Zodiac and other serial killers. You can find his website at: http://radiansandinches.com/Home_Page.html
There you can read the journal he edits and submit articles on this fascinating subject. Please let him know that The Podcast of Doom sent you.
