The Zodiac Killer, the Northern California serial killer who killed 5 and injured 2 victims, has never been caught to this day. There have been many suspects in the case, but now there is a Baton Rouge man who is saying that his biological father was the infamous serial killer.

Gary L. Stewart, a vice president at the cleaning company Delta Tech Service in Baton Rouge, has a new book out called "The Most Dangerous Animal of All: Searching for My Father ... and Finding the Zodiac Killer" which is published by HarperCollins. In the book, he claims that his biological father, Earl Van Best, Jr., who had since passed away, is the notorious Zodiac Killer.

This past Tuesday, when asked about the book, police in northern California said they weren't aware of it or its claims.
