The Zodiac Killer. His attacks were accompanied by phone calls & letters that taunted police and threatened harm on others. Just what do we really know about these killings? What evidence have investigators collected over the years? Does anyone truly know the identity of the killer as some authors have recently suggested? Is this case still being researched? Is the killer still alive? Joining us was Mike Morford. He runs a Zodiac killer website and has a lot to say on these unsolved crimes and the claims made by authors who say they have all the answers.
