The FBI turned the pressure up on [Ivins], isolating him at work and forcing him to spend what little money he had on lawyers to defend himself. He became increasingly stressed. His therapist reported that Ivins seemed obsessed with the notion of revenge and even homicide. Then came his suicide (which, as Eric Nadler and Bob Coen show in their documentary "The Anthrax War," was one of four suicides among American and British biowarfare researchers in past years). Since Ivins's odd behavior closely fit the FBI's profile of the mad scientist it had been hunting, his suicide provided an opportunity to close the case. So it held a congressional briefing in which it all but pronounced Ivins the anthrax killer.
But there was still a vexing problem—silicon.
Silicon was used in the 1960s to weaponize anthrax. Through an elaborate process, anthrax spores were coated with the substance to prevent them from clinging together so as to create a lethal aerosol. But since weaponization was banned by international treaties, research anthrax no longer contains silicon, and the flask at Fort Detrick contained none.

Yet the anthrax grown from it had silicon, according to the U.S. Armed Forces Institute of Pathology. This silicon explained why, when the letters to Sens. Leahy and Daschle were opened, the anthrax vaporized into an aerosol. If so, then somehow silicon was added to the anthrax. But Ivins, no matter how weird he may have been, had neither the set of skills nor the means to attach silicon to anthrax spores.
At a minimum, such a process would require highly specialized equipment that did not exist in Ivins's lab—or, for that matter, anywhere at the Fort Detrick facility. As Richard Spertzel, a former biodefense scientist who worked with Ivins, explained in a private briefing on Jan. 7, 2009, the lab didn't even deal with anthrax in powdered form, adding, "I don't think there's anyone there who would have the foggiest idea how to do it." So while Ivins's death provided a convenient fall guy, the silicon content still needed to be explained.
The FBI's answer was that the anthrax contained only traces of silicon, and those, it theorized, could have been accidently absorbed by the spores from the water and nutrient in which they were grown. No such nutrients were ever found in Ivins's lab, nor, for that matter, did anyone ever see Ivins attempt to produce any unauthorized anthrax (a process which would have involved him using scores of flasks.) But since no one knew what nutrients had been used to grow the attack anthrax, it was at least possible that they had traces of silicon in them that accidently contaminated the anthrax.
Natural contamination was an elegant theory that ran into problems after Congressman Jerry Nadler pressed FBI Director Robert Mueller in September 2008 to provide the House Judiciary Committee with a missing piece of data: the precise percentage of silicon contained in the anthrax used in the attacks.
The answer came seven months later on April 17, 2009. According to the FBI lab, 1.4% of the powder in the Leahy letter was silicon. "This is a shockingly high proportion," explained Stuart Jacobson, an expert in small particle chemistry. "It is a number one would expect from the deliberate weaponization of anthrax, but not from any conceivable accidental contamination."
Nevertheless, in an attempt to back up its theory, the FBI contracted scientists at the Lawrence Livermore National Labs in California to conduct experiments in which anthrax is accidently absorbed from a media heavily laced with silicon. When the results were revealed to the National Academy Of Science in September 2009, they effectively blew the FBI's theory out of the water.
The Livermore scientists had tried 56 times to replicate the high silicon content without any success. Even though they added increasingly high amounts of silicon to the media, they never even came close to the 1.4% in the attack anthrax. Most results were an order of magnitude lower, with some as low as .001%.
What these tests inadvertently demonstrated is that the anthrax spores could not have been accidently contaminated by the nutrients in the media. "If there is that much silicon, it had to have been added," Jeffrey Adamovicz, who supervised Ivins's work at Fort Detrick, wrote to me last month. He added that the silicon in the attack anthrax could have been added via a large fermentor—which Battelle and other labs use" but "we did not use a fermentor to grow anthrax at USAMRIID . . . [and] We did not have the capability to add silicon compounds to anthrax spores."
