Incident Summary:

10/29/2001: In one of several anthrax-related incidents, Kathy Nguyen, an employee at the Manhattan Eye, Ear and Throat Hospital in New York, New York, U.S.A. was diagnosed with the inhalation form of anthrax. She died on October 31st. It was not clear how she contracted the disease, although she had previously worked in the stockroom of the hospital. The perpetrator(s) of this incident was not known. No group claimed responsibility for the attacks. Concluding an extensive investigation, the Federal Bureau of Investigation identified microbiologist Dr. Bruce Ivins as the sole perpetrator. However, Ivins committed suicide in 2008, having not been arrested or prosecuted. An independent review of the scientific evidence by the National Academy of Science indicated that it was essentially inconclusive.
