Incident Summary:

10/26/2001: In one of several anthrax-related incidents, anthrax was discovered at the off-site facility that sorts mail for the U.S.A. Supreme Court in Washington, D.C., U.S.A. Cross-contamination with anthrax-laced letters to other areas was suspected. 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.
