    leigh allen, the one

    I've always been intrigued by the statements from these brothers, and it amazed me that no one had done anything about it... until now! Without a doubt, Arthur Leigh Allen was, is, and will be the number one suspect-miles ahead of anyone else, light-years, even. There's a huge amount of circumstantial evidence, way beyond the ordinary, and when you add in the experiences of these brothers, I've got no doubt he was the killer. Let's not forget that a survivor from the Lake Berryessa side and Michael Mageau identified him as their attacker, among a ton of other things. A narcissist and an egomaniac with two faces. Hopefully, his guilt can finally be confirmed, because there's no one else who even comes close to him.

    Closure ?

    Most of us have seen the Fincher movie covering the facts ( but having watched this series , the aforementioned facts are brought into question ) , but if you haven't , I'd recommend that you do , to give a reasonable perspective . A serial killer - one of several at the time - terrorised the California area throughout the sixties and seventies . Part of his modus operandi was taunting both the Press and the Police departments of the affected crime scenes . The movie was released in 2007 and they couldn't portray several details as the prime suspect was at that point unproven . This series unravels why and it doesn't show the detectives in the original investigation in a great light . Add to that , the incredible involvement of a whole family , who could be deemed complicit , if not naive in the extreme .

    After this, how can we not think that Arthur Leigh Allen was the Zodiac Killer?

    The Zodiac Killer must be one of the most compelling cases in the history of forensics.

    A monstrous being, ahead of its time.

    When you read the stories you can't help but feel sorry for the victims, their families and the police. No one was prepared for a being of this magnitude.

    This miniseries gives us a very interesting point of view.

    Arthur Leigh Allen was always the number 1 suspect, all the circumstantial evidence, the fact that he had been in the area of several murders on the same days that they occurred and even his identification by the survivors.

    However, he could never be locked up and died prematurely from his kidney disease.

    In the Seawater stories there is so much pain, so much darkness lived, so many traces followed that it is impossible not to follow this conjecture. ALA was the Zodiac Killer, without a doubt. Egomaniac, narcissist, abuser, with extremely useful skills and talents... all the combo to do what he surely did.

    It's a shame that David has passed away and will not be able to see the end of this story. I am left frozen by the bond with his mother and how she was/could have been an accomplice to this for so many years. A destroyed family, a sister who would clearly be one of the next victims and who was saved by a miracle.

    Finally, the hope that the knife he gave to Connie's son will finally reveal that truth that has been awaited for more than 50 years...

    Without a Doubt

    After seeing this well-done and thoroughly researched series, Arthur Leigh Allen was the Zodiac Killer. Of this I am certain. Others can drone on about circumstantial evidence and speculate and doubt all they want, but anyone who doesn't think it was Allen after seeing this series is deeply in denial or just doesn't want to believe the obvious. What it really boils down to is this: many people, especially armchair detectives, love a good mystery, so much so that they hope the mystery won't be solved. When it involves infamous criminals, such cases take on a life of their own and they want the mystery to continue. So when a longstanding case is finally solved, they're actually disappointed because there's no longer any mystery in their lives. They also refuse to believe that someone other than themselves solved it. It's all rather sad.

    Gives a sense of actual closure

    Zodiac is one of my favorite films of all time, and this doc adds a new compelling layer to it; a companion piece, sort of. Interviews include the real Robert Graysmith and footage of Arthur Leigh Allen and the people he hurt. It confirms how much attention to detail was put into the movie, and how important it was to some people who interacted with the main suspect. There is a lot of information I wasn't aware of and unlike most unsolved serial killer documentaries where they almost leave you wondering what the point of what you watched was, this one provides some semblance of closure. It's absolutely compelling and worth a watch.
