Excerpts:
September 4, 2001 (approx.):
On approximately this date, a "weird love letter to Jennifer Lopez" is sent to The Sun, a tabloid with offices in Florida. "But inside the oddly-worded letter was what was described as a 'soapy, powdery substance' and in the pile of that a cheap Star of David charm." The letter was handled both by Ernesto Blanco, who contacted anthrax, and Bob Stevens, who died of anthrax. The letter was thrown away, so it's not known if it contained anthrax. [Newsweek, 10/8/01] Could the letter have been part of a pre-9/11 series of anthrax attacks reported by the New York Post (see before September 11, 2001)? The only specific target mentioned by the Post was Fox News Channel's Bill O'Reilly. [New York Post, 11/1/01] Bob Stevens was admitted to a hospital on October 2; the period between anthrax exposure and symptoms can be up to eight weeks. The anthrax attacks targeted media outlets, sending both real and hoax letters. Could this have been part of that series? Newsweek also reports a Middle Eastern intern working at the Sun that summer left a curious farewell e-mail. [Newsweek, 10/8/01]
before September 11, 2001:
In a story seemingly unreported anywhere else, the New York Post later claims that a series of hoax anthrax letters is sent out from Indianapolis, Indiana, at some point not long before 9/11. The FBI allowed the Post to see copies of these letters, which had handwriting and other features remarkably similar to the later letters containing real anthrax. [New York Post, 11/1/01]
Additionally, the fact that it's taking a government agency years to conclude that a terrorist was behind an act that, by its very nature, constituted "terrorism", is no great source of confidence in the future.
