The USDOJ has made a number of documents pertaining to the Amerithrax investigation available online:

Highlights so far, just from an affidavit written to support a search warrant by USPS Postal Inspector Thomas Dellaferra:

* The type of anthrax identified in the letters sent out after 9/11 was traced via a chemical signature back to Fort Detrick, where Dr. Bruce Edward Ivins worked as an anthrax researcher. The postal service traced the envelopes back to Fort Detrick as well.

* Bruce Ivins normally worked 7:30 a.m. to 4:45 p.m., and all labs, including (of course) labs used to work with "hot" toxins like anthrax, were accessed with magnetic keycards. The keycards generally reflected a given worker's typical pattern of entry and re-entry. The affidavit by Inspector Dellaferra states the following about Ivins: "Beginning in mid-August 2001[,] however, there was a noticeable spike in Dr. Ivins's evening access to the B3 hot suite."

* Bruce Ivins was having definite mental health issues in 2000 and 2001. On April 3, 2000, Ivins wrote the following in an e-mail: "Other times it's like I'm not only sitting at my desk doing work, I'm also a few feet away watching me do it. There's nothing like living in both the first person singular AND the third person singular!"

* On July 4, 2000, Ivins said the following in an e-mail message to a friend: "The thinking now by the psychiatrist and counselor is that my symptoms may not be those of a depression or bipolar disorder, they may be that of a 'Paranoid Personality Disorder.'" In a different e-mail written three days later, Ivins specifically mentioned the National Enquirer and stated he never wanted to see the headline, "PARANOID MAN WORKS WITH DEADLY ANTHRAX!!!" One of the victims of the anthrax letters was a photo editor at the Enquirer.

* Dr. Ivins wrote an e-mail on September 26, 2001 that read in part, "Osama bin Laden has just decreed death to all Jews and all Americans." Dellaferra notes that Ivins's language was "similar to the text of the anthrax letters postmarked two weeks later warning 'DEATH TO AMERICA,' 'DEATH TO ISRAEL.'"

* In December, 2001, Bruce Ivins wrote another e-mail detailing some poems he'd made up about himself and "the person in my dreams." One stanza from one of the poems:

"I'm a little dream-self, short and stout
I'm the other half of Bruce when he lets me out.
When I get all steamed up, I don't pout.
I push Bruce aside, then I'm Free to run about!"

* A separate affidavit from FBI agent Marlo Arredondo sought information about Bruce Ivins's e-mail accounts. Ivins used the following:
-- KingBadger7@aol.com
-- goldenphoenix111@hotmail.com
-- bruce.ivins@amedd.army.mil
-- and of course, jimmyflathead@yahoo.com.
According to Arredondo, Ivins used these addresses to "facilitate an obsession with a sorority group linked to the location of the anthrax mailings." Ivins also used screen names such as "Ed Ivings," "BigSky" and "prunetacos."

* Ivins, using some of the names above, posted messages at AboveTopSecret.com, an online forum devoted to discussions of conspiracy theories, the paranormal, and supernatural subjects. Ivins posted messages and began threads about the Kappa Kappa Gamma sorority. Here is a thread at AboveTopSecret.com discussing the "removal of College Fraternity Secrets Threads." Note that "prunetacos" posted in that thread about other boards where he'd discussed the Kappa Kappa Gammas. See also: a list of 50 posts left by "Prunetacos" at GreekChat.com. Many of the Greek Chat posts discuss Kappa Kappa Gamma as well.
