Can you crack this message?

I've figured out just a little bit of it. I found this at zodiackiller.com
At the very end on the left it clearly says: Zodiac killer. I found this out by myself and that might be why the website is called that and btw I found out something else too, if you take a look at it from a far distance, you can see a figure... a man.

I'm trying to figure out what those filled in circles represent, cant..
This is a tough one.

This is a letter written by the Zodiac Killer a murderer with cryptic messages from about the 80s. These letters were hard to decrypt which is why he got away with the murders of over 8 people. He had been inactive since the late eighties.

He is the reason the Origami Killer was created for Heavy Rain, the cryptic messages and all

It's a good idea to not always project your intelligence on other people who actually know shit at the right time.

No, I didn't look this up. Realize that people find their information at places other than the Google search engine, it's actually possible.
