(CNN) — The FBI announced that it has concluded its investigation into the 2001 anthrax mailings, saying Friday that a biodefense researcher carried out the attacks alone.
The anthrax letters killed five people and sickened 17 shortly after the September 11, 2001, terrorist attacks. The letters, filled with bacterial spores, were sent to Senate Democratic leaders and news organizations.
“By 2007, investigators conclusively determined that a single spore-batch created and maintained by Dr. Bruce E. Ivins at the United States Army Medical Research Institute of Infectious Diseases (USAMRIID) was the parent material for the letter spores,” said a report released Friday by the FBI.
