I wrote a book on the similarities between Ted Kaczynski, the Unabomber, and the Zodiac Killer, which shows numerous possible connections between the two. (The Unabomber and the Zodiac, 2007). But ... and this is a big but ... there has never been any smoking gun evidence connecting Zodiac with any particular person, and it doesn't appear that there's any such smoking gun in this case.

I always wondered if Zodiac was some tool falsely claiming responsibility and sending his notes and codes to police and media for giggles.

Meanwhile, the actual serial killer(s) appreciate the diversion.

Regardless of the lack of smoking gun evidence, do you personally believe they are one in the same?

I used to post on the zodiackiller.com message board a little bit and I remember that theory well. Bet you were on there too :)
