Given the spacing, it wouldn't surprise me if the code were based upon some other text- it could be encoded based upon a page of a book, for example, or even a letter the creator had written.

For example, you could make a very simple cypher based on "Timothy" like so:

T-I-M-O-T-H-Y

could translate to (letters become numerical place in alphabet)

20-9-13-15-20-8-25

and then if you were encoding "secrets"

S-E-C-R-E-T-S

which would be

19-5-3-18-5-20-19

and then added "timothy" to "secrets", "wrapping around" when something equaled 27 or more (27=1, 28=2, etc.) you would get

13-14-16-7-25-2-8

which translated back into letters gets you

M-N-P-G-Y-B-R.

In such a case, it could be very difficult indeed to decode the original message without knowing what text the thing was based on.

In my opinion this kind of thing is probably either:
1. A clever way to confuse the police if you murdered this man
2. It could be this guy saying, "if i'm going to kill myself, I might as well make the police involved confused as hell." *scribbles random letters on paper*
I thought the same thing, the murderer just scribbled random crap down to screw with the cops.

Ah, this is what I love about the internet, merely being told that something can't be done is reason enough to do it

I'm no cryptanalyst, but if I had to guess i'd say this guy came up with some kind of one-time pad. Those are supposed to be mathematically unbreakable unless you have a copy of the original pad used to encrypt it.
This is my guess, from the looks of it it's probably a tier one or two.

Only 4 lines of paragraphs are without (). What could their meaning be?

Some letters are written in bold, as if to point them out especially. What for?

In the upper corner there's PI in a circle. Could this be a mathematical number but written in letters?

I MIGHT continue with this. But probably not...

EDIT; ... God damn it. My ego have gotten the better of my interest.

Second note have a peculiar sense to end with E's. And most lines are equipped with SE's. It obviously stands for something, but what?
And, it have more a lack of parentheses this time. Only two are pointed out in the second paragraph.

The only thing that stuck out was that the letters TFRNE is repeated twice - 2nd & 8th row.

G'night.

Well knowing the internet a couple of obsessives will have this solved in a few months.

Someone get this to 4chan, god knows that behind all that kiddy porn, justin bieber murder attemtps, and massive youtube trolling, if they get their mind to it they could probably solve this riddle, only to troll the fbi and the dead guys family afterwards

Never gonna let you down,
Never gonna run around and desert you"

if the FBI hasn't cracked this yet, then it's probably gibberish. in my amateur opinion, there are way too many repeated letter patterns for this to be any kind of polyalphabetic cipher and a simple substitution cipher would be trivial to solve.

the dashed lines like "KLSE-LKSTE-TRSE-TRSE-MKSEN-MKSE" on the second page are particularly suspicious in how repetitive the letter patterns are.
The repeated letters call to mind something like ADFGVX [http://en.wikipedia.org/wiki/ADFGVX]

No wonder they can't make sense of the thing. Some glyphs are a tad on the incomprehensible side.

Never thought the FBI could be stumped by a code. Can't they just digitize it and brute-force it or something?
If it is illogical pattern then computer can not solve it. Unless you happen to have a computer that is able to think like a human... Hey I got one, it is called Human brain.

The 4chan/sci/ boards are now officially on it.

Also, i bet this is either a one-time pad(which would make it as incomprehensible as illogical gibberish), or illogical gibberish, used to troll the FBI with his suicide.
