Yeah, right. The story is quite good actually, but this guy is making false claims. CNN and several other major news sources have jumped all over this story. Basically, there was this creepy guy named Earl Best Jr, who had married a 13 year old girl (who was pregnant) in California back in the early 60s. They got in some trouble and took off. Best ditched the baby in the stairwell of an apartment building. Years later the mother contacts her now grown up son, Gary L. Stewart. He sets out to find his birth father, and discovers he was the Zodiac Killer. This has been making headlines all around the country for the last few days, and this guy is selling a lot of books, but he is full of crap and is cashing in on the suffering of several families of Zodiac victims. What a scumbag!!
