The Zodiac a Merchant Marine?

20 Jul

If you believe Robert Tarbox, the Zodiac killer was a merchant marine. According to Tarbox, now 82, in the early 1970s a man came into his office stating that he was a merchant marine and that he was responsible for the Zodiac killings. He asked what the consequences would be if he turned himself in. Tarbox told him the outcome would not be good, that he could receive the death penalty or at best life imprisonment. The man left the office and was never seen again. Tarbox never told anyone about this until now, client privilege and all that being in play.

Over the years many names have cropped up as the possible Zodiac killer but none have panned out. The most recent, Arthur Leigh Allen, went all the way to DNA testing before his involvement in the killings was ruled out. The zodiac remains one of the great mysteries in criminal history.

    I’ve examined the handwritings of the Zodiac in great detail and compared them to the handwritings of various suspects. From the point of view of a court-qualified handwriting expert, it’s my opinion that none of the identified suspects matched the Zodiac letters. I wonder whether Tarbox got anything in writing from this merchant marine.

      Sheila—Apparently he didn’t–at least the article mentions nothing like that and I suspect it would have if such evidence existed. Too bad.

      Tarbox didn’t but I do. I have the writing but in cursive writing. I just got his DD214 Forms too. Just got them the other day. I’m still going thru them as we speak- I am seeing some handwriting that’s not in cursive. Some. I just made a picture comparison of this Merchant seaman & you can watch it here ..>>>

      …you be the Judge- ANY professional handwriting experts feel free email me for these handwriting examples. Email me at; Hurry before I change my mind. He was my Uncle. He was a Merchant Marine Captain. bye~!

    I leave here my personal opinion on the case. Zodiac killer was indeed connected with Marine. It’s silly how many wrong profiles have been made. There is nothing complicated about his profile…
    I mean, he used the Zodiac brand and name of a watch company! He used a Luger (military fanatism), he used cyphers… it’s not like Jack the ripper case! He left lot of elements behind him, and he still fooled people. It’s of course related to the Marine military service (maybe he was even the son of some Marine officer, I bet is been covered for years and now the case is simply impossible to solve).

      because Robert Tarbox is the actual zodiac killer, he feels guilty now especially for the Allen.

    Is Tarbox still alive? If so, can anyone provide me with contact details? I believe that I may be able to convince him to identicy the man he spoke to in his office that evening.
