Author is used to using contractions and made an attempt to seperate the contraction can't. Likely someone with good comfort level with American idioms.
However, the first letter of the first word of each sentence is written in slightly larger upper case lettering. Also, the first letter of all proper nouns (like names) is slightly larger. This is apparently the author's way of indicating a word should be capitalized in upper case lettering.
Author understands the importance of capitalization, and it appears that he sub-subconsciously "capitalized" where he should have.
The names and address on each envelope are noticeably tilted on a downward slant from left to right.
Author is right-handed and is not used to writing on non-ruled paper. Very familiar with writing in western form (left to right).
KEY POINT
The author uses dashes ("-") in the writing of the date "09-11-01." Many people use the slash ("/") to separate the day/month/year.
Author may be a computer user as most software packages will not allow dates to be written with a slash as that has a mathematical value associated with it.
My Analysis
Author is a western born and raised individual. Likely male, intelligent, under 50, with plenty of experience with computers. Likely not a programmer, but maybe a power user. Database entry or similar job at night would be a good starting profile. He has to have access to chemisty equipment of moderate sophistication, so check Universities in Trenton area first.
It would seem to me, a real amatuer, that the downhill writing would indicate someone who wasn't used to writing from right to left. The spacing between the individual letters was a bit wide, also, reminding me of the wide spacing that appears in Arabic writing...
Someone here said that this indicates that the person is right-handed, but I'm right-handed
and my writing/printing has always slanted upward as I go to the right, unless I am being careful.

That's the Microsoft Word "small caps" font style.
It's also the way the Cyrillic alphabet is written. Cyrillic evidently lacks lower case. Might he be a former employee of Biopreparat?
This is also the way capitalization was done on a very old typewriter we had. "Upper case" and "lower case" letters were the same, except "lower case" letters were smaller than the "upper case" ones.
"The author uses the words "can not," when many people prefer to spell it as one word, "cannot." "Author is used to using contractions and made an attempt to separate the contraction can't."
