I was recently interviewed by Ned Dehan of Black Box Online Radio as part of the Interviews with the Experts series put together by Jack Cooper from the Zodiac Killer Channel on YouTube. We talked about a wide variety of subjects including: how I became interested in the Zodiac, various aspects of the Southern California crimes, celestial navigation, the killer’s use of the compass rose, some of the elements of the killer’s methodology, and quite a bit more.
