I've mentioned it several times on this board.... "The Zodiac Killer" case is the one that intrigued me the most and it's by FAR the case I've read the most about. I still check in on it occasionally although I'm not expecting that they'll eventually find out who he was. It's possible.... but I think Zodiac goes the way of Jack the Ripper... we'll never know, not for sure anyway.
Just a guess on my part but I'd say the Zodiac is the most infamous of all murderers... at least in the USA? Manson is up there but the Zodiac case is unsolved. And the way he went about it... taunting the police, the public. Clues, ciphers, letter after letter after letter.
I often wonder if he ever regretted his crimes. Did he go to the grave feeling redeemed or did he remain unrepentant to the very end? Or hell... very little chance but he could still be alive if he was a young man when he committed his crimes.... I very very very much doubt he's still alive. - JamesJM
