I'm not sure I see the similarity that you do. In the first picture, the horizontal line that crosses the "f" in that of the Zodiac letter is very straight while in you POI letter is has a downward curve on each side. The "g" is also different with the tail being off to the left in the Zodiac letter and straight down in your POI letter. These two letters look more similar to one another in the second set of letters. For example, in the second letter, the tail of the Zodiac's "g" does change to be more straight downward, though. Look at the "r" though in the second POI letter compared to the "r" in the Zodiac letter. The Zodiac letter is well-formed with the curved line staying connected to the straight line until they are supposed to separate at the top where in the POI letter the lines separate, almost looking like a "v". Also, the "u" and the "e" in the second POI letter is quite different from those same letters in the Zodiac letter.
All of this being said, I'm no handwriting expert and I would like to know more of your story. Is there another thread or post where you explain the background on how you came to suspect your POI?
Well, you have to realize, my note was written in 2010 and handwritting changes over time, but I have more I will be showing, it gets better.
I have not written a post that completely explains why I suspect my POI. Lets say this, I was his best friend for almost 3 years, and we spent many,many hours researching these codes,solutions,etc in a long defunct treasure hunt. I got to know his dark side some, and his personal feelings of things. They way he speaks almost makes you think he was once SLA. A long story there. But what go me going is this:
he said to me- I am sick of living,unwilling to die, and I believe he said it more than once. He is rebounding from divorce. He once threatened to kill a relative of mine, and I saw the threat(30 years ago) take place, and saw something in his eyes back then that has only now surfaced in relation to oher things I have discovered. Coincidence became a string of connections, another long story. I then discovered he resembled exactly the suspect, and he was from Oakland and listed Pleasanton as his highschool. I kept making connections from there. I also know he is into some evil deep stuff and I am sorta leary of telling much more until he has been at least considered and checked out. My work here is to try and show the relationship between the clues he gave me that he was Zodiac in the NOT SO MANY WORRDS way and his abilities to be the one. I already have proof his name is encoded in the Excorsist letter, but WS wont let that post be published, its a liablity thingy.. He also gave me some Halloween glasses with eyes in them. This if you ask me, would be something the ZODIAC would do when he chose a new opponent. I think he wants to be caught and is frustrated in being insolved. Maybe he found God, who knows, and he chose me to be the one to end the game.
None the less, I am still waiting for a reply from who ever it will be that takes me serious in law enforcement. I called cold case again the other day, but who knows if ever that call will be returned. I emailed Napa and the Napa sheriff with some stuff top, and a comparrison photo with the sketch, I defenitely know that there is a connection, I hope someone in law enforcement connects the Dots. I have added many posts here, you should look at them all. I may be Quack, but I am not a duck.
