Anthrax Redux: Did the Feds Nab the Wrong Guy?

By Noah Shachtman

Finally, the investigation was over. The riddle solved. On August 18, 2008—after almost seven years, nearly 10,000 interviews, and millions of dollars spent developing a whole new form of microbial forensics—some of the FBI’s top brass filed into a dimly lit, flag-lined room in the bureau’s Washington, DC, headquarters. They were there to lay out the evidence proving who was responsible for the anthrax attacks that had terrified the nation in the fall of 2001.

It had been the most expensive, and arguably the toughest, case in FBI history, the assembled reporters were told. But the facts showed that Army biodefense researcher Bruce Ivins was the person responsible for killing five people and sickening 17 others in those frightening weeks after 9/11. It was Ivins, they were now certain, who had mailed the anthrax-filled letters that exposed as many as 30,000 people to the lethal spores.
