February 19, 2010 - The Justice Department, FBI and U.S. Postal Inspection Service today announced that the investigation into the 2001 anthrax attacks, which killed five individuals and sickened 17 others, has formally concluded.
Earlier today, representatives of the FBI and Justice Department provided a 92-page investigative summary along with attachments to victims of the attacks, relatives of the victims and appropriate committees of Congress. This document sets forth a summary of the evidence developed in the "Amerithrax" investigation, the largest investigation into a bio-weapons attack in U.S. history. As disclosed previously, the Amerithrax investigation found that the late Dr. Bruce Ivins acted alone in planning and executing these attacks.
The investigative summary and the attachments are now accessible to the public and have been posted to the Justice Department Web site at www.usdoj.gov/amerithrax under the Freedom of Information Act. In addition, roughly 2,700 pages of FBI documents related to the Amerithrax case are now accessible to the public and have been posted to the FBI website at http://foia.fbi.gov/foiaindex/amerithrax.htm under the Freedom of Information Act.
The Amerithrax Task Force, which was comprised of roughly 25 to 30 full-time investigators from the FBI, U.S. Postal Inspection Service and other law enforcement agencies, as well as federal prosecutors from the District of Columbia and the Justice Department’s Counterterrorism Section, expended hundreds of thousands of investigator work hours on this case. Their investigative efforts involved more than 10,000 witness interviews on six different continents, the execution of 80 searches and the recovery of more than 6,000 items of potential evidence during the course of the investigation. The case involved the issuance of more than 5,750 grand jury subpoenas and the collection of 5,730 environmental samples from 60 site locations.
