Good points… Then also the timing of this coming out in 1986, when the book is published Is interesting, could be a clever forgery. (or not too clever and I’m reading way too much into it.)

I tend to lean towards the canonical five. It wouldn’t even surprise me if those five murders were carried out by two or three killers either working as a tem or as a solo.

I don’t believe the Zodiac was a mastermind criminal who murdered many people over without the police capturing him. I think he was lucky that the police didn’t posses the technology that we they have today. The police in the late Sixties weren’t up to the challenge of cracking a case the Zodiac’s. The smartest thing Zodiac did was quit after the Paul Stine attack.

Only 1 of his 4 attacks required any type of tactics or skills: the Berryessa maybe required some sort of blueprint. It helped that the park was virtually empty at that time of day and that late in the season. Otherwise the other attacks were based on the IRA hit and run strategy later picked up by the American mobs during Prohibition.

I also think that taunting the police and terrorizing the public were the Zodiac’s primary purposes for his spree. The killing was secondary. After the bloody mess of Berryessa and the assassination of Paul Stine I think he had had a belly-full of gore. I think he graphed on the kidnapping of Kathleen John and the disappearance of Donna Lass to keep the flames of his legend alive.

The Zodiac was that smart, tough, skillful or homicidal to do all of the things many of you think he did during his career. Turning the Zodiac into an elusive demonical evil spirit maybe was part of his plan.

PS
This isn’t a slap at you those of you who believe that Zodiac operated on a larger scale. You very well all could be correct. I especially respect Sandy Betts, Morph and others of my fellow posters who have researched the Zodiac in greater detail than me. I enjoy reading all of your posts and they provide food for thought.

I certainly agree with this part and doubt very much that he engaged in any sort of homicidal violence after 1969. However, I’ve recently come around to the possibility that he may have committed other crimes before he became the Zodiac (not necessarily murders) that he never took credit for, believing them to be "invalid" once he came up with his grand persona. Given that he was likely a fan of comic books, the idea that Zodiac may have retconned his previous criminal activity out of existence (at least personally) holds quite a bit of appeal.

Domingos/Edwards for sure.

Hard to put a number on it. I’m up in the air about Domingos/Edwards & Cheri Jo(I def think he wrote the letters), I’m gonna go out on a limb and say just the confirmed Z Victims we know of,and he never killed again after Stine. Although, if rumors are true that size 10.5 wingwalker tracks were found at the D&E crime scene,I’d have to change them to likely Z Victims

Is that rumour the unreleased evidence they have linking the suspect "Sandy" ?
From the 1972 interview?
