Hmmmm... None of the non-trivial phrases popped out of a Google search, either webpages or usenet or thru BoardReader (message boards search engine), so I doubt this individual has done much posting online or has a website. (Wait - I didn't search FR... !)

He may be a naturalized US citizen:

The United States strives to provide freedom for their people. Do we really have personal freedom? I've lived here for many years, and I see much limitation.

His English is impeccable.

Holy Toledo - I just noticed something:

I'm here to help you realize/ understand that you will live no matter what! It is up to you people to open your hearts and minds. There is no such thing as death. The people I've dismissed from this reality are not at all dead.

This guy has already killed people.

(He's already killed more than one person, but not with his mailbox bombs. He's only injured six with that method.)

Six people were injured by explosions in Illinois and Iowa on Friday. Six pipe bombs were also found Saturday in rural areas of Nebraska, but none went off. They were later detonated harmlessly by authorities.

TERRORIST PLOT TO BOMB NEW YORK SUBWAY SYSTEM (8/01/97)

NEW YORK CITY (ENN) - Members of the New York City Joint Terrorism Task Force on Thursday made a raid on a Brooklyn apartment and seized several pipe bombs and arrested three men, described as being "Middle Eastern." The Task Force, comprised of federal, state and local law enforcement officers, are now investigating to see if there was a possible plot to bomb the New York City subway system and other targets.

Or maybe he thought he would kill some people- which in fact didn't happen.
