The FBI’s six-year investigation into the 2001 anthrax attacks that killed five people, closed a Senate office building for months and nearly paralyzed the U.S. Postal system was the largest inquest in its history and involved 9,000 interviews, 6,000 subpoenas, and the examination of tens of thousands of photocopiers, typewriters, computers and mailboxes.
But it failed to find evidence that identified the anthrax killer or a witness to the mailings, The Wall Street Journal reported Sunday in an opinion piece titled “The Anthrax Attacks Remain Unsolved.”
The Journal notes that less than a week after the apparent July 29, 2008, suicide of Bruce Ivins, a senior biodefense researcher at the U.S. Army Medical Research Institute of Infectious Diseases at Fort Detrick, Md., the FBI declared him to have been the sole perpetrator of the attacks. But, according to the Journal, there is troubling evidence that Ivins could not have acted by himself.
