October 5-November 21, 2001: Anthrax Letters Kill Five, Heighten Terrorist Attack Fears

Two waves of letters containing anthrax are received by media outlets including NBC and the New York Post (see September 17-18, 2001), and Democratic senators Tom Daschle and Patrick Leahy (see October 6-9, 2001). The letters sent to the senators both contain the words “Death to America, Death to Israel, Allah is Great.” Five people die:
October 5: Robert Stevens, 63, an employee at the Sun, a tabloid based in Florida.
October 21: Thomas Morris Jr., 55, a postal worker in Washington, DC.
October 22: Joseph Curseen Jr., 47, a postal worker in Washington, DC.
October 31: Kathy Nguyen, 61, a hospital employee in New York City.
November 21: Ottilie Lundgren, 94, of Oxford, Connecticut.
At least 22 more people get sick but survive. Thirty-one others test positive for exposure. As a result of these deaths and injuries, panic sweeps the nation. On October 16, the Senate office buildings are shut down, followed by the House of Representatives, after 28 congressional staffers test positive for exposure to anthrax (see October 16-17, 2001). A number of hoax letters containing harmless powder turn up, spreading the panic further. [South Florida Sun-Sentinel, 12/8/2001; Associated Press, 8/7/2008] Initially it is suspected that either al-Qaeda or Iraq are behind the anthrax letters (see October 14, 2001, October 15, 2001, October 17, 2001, and October 18, 2001). [Observer, 10/14/2001; BBC, 10/16/2001] However, by November, further investigation leads the US government to conclude that, “everything seems to lean toward a domestic source.… Nothing seems to fit with an overseas terrorist type operation (see November 10, 2001).” [Washington Post, 10/27/2001; St. Petersburg Times, 11/10/2001]
