The author of a new book claims he knows who the Zodiac Killer is.

The Zodiac Killer terrorized the San Francisco bay area in the late 1960s where he killed at least five people. Over the years, a number of possible suspects have been named by police and private investigators, but no one has ever been arrested.

Now, former CHP officer Lyndon Lafferty claims the Zodiac Killer is a 91-year-old alcoholic living in Solano County. But he has not revealed that person's real name.
