The Anthrax Letters
In the weeks after September 11, 2001, letters carrying anthrax spores reached newsrooms and the U.S. Senate. The first batch, postmarked in Trenton, New Jersey, on September 18, went to media outlets including NBC News and the New York Post. Two more, dated October 9, were addressed to Senators Tom Daschle and Patrick Leahy. Five people died and at least 17 others were sickened. The FBI investigation, called Amerithrax, spent years on a different scientist, who was publicly labeled a person of interest and later exonerated; in June 2008 the Justice Department settled his lawsuit for $5.8 million.
The FBI's final answer was Bruce Ivins, an anthrax researcher at the Army's Fort Detrick laboratory in Maryland. Ivins died by suicide on July 29, 2008, as prosecutors were drafting charges, and the case was formally closed on February 19, 2010. The core evidence was genetic: four mutations linked the letter spores to a flask in Ivins's lab labeled RMR-1029. The FBI later counted 419 people who had access to that lab or had received samples from the flask.
Outside reviews were cooler. In 2011 a National Research Council committee, which the FBI had requested, said science alone could not settle where the spores came from and that alternatives were not fully tested. In 2014 the Government Accountability Office found the FBI's genetic testing lacked consistent standards. The FBI says science was not the sole basis for its conclusion. No court ever weighed the case.
Red flags: 1 of 6 What these mean
Records destroyed or withheld
The 2011 National Research Council committee did not review classified materials and recommended further review of classified FBI and Justice Department work it could not examine. Source
- Official story changed
- Investigated by the accused
- Evidence held by an interested party
- Denied, then admitted
- Witnesses dismissed
Verdict: UnprovenThe FBI's case against Ivins was never tried, and independent reviews found its science not definitive; neither his guilt nor any alternative has been established.
