Many leads, many dead ends
Frustration inside the FBI's anthrax investigation: a so-far perfect crime
Rosenberg and some of her peers say they've named names to the FBI of who they think did it. The FBI says none has panned out (chemical analysis has shown the powder was not made using any known U.S. technique). Officials say Rosenberg is "misinformed and uninformed." The bureau also has pooh-poohed a recent memo written by two biodefense experts at Johns Hopkins University. They concluded that one of the hijackers who went to a Florida doctor last June seeking treatment of a "black lesion" or a "gash"--the description varies--probably suffered from cutaneous, or skin, anthrax. But the FBI says exhaustive testing for anthrax anywhere the hijackers were present came up empty.
In its investigation, the FBI has had other challenges. What if one of its scientific advisers is, in fact, the killer? Consider the story of William Patrick, patriarch of the nation's bioweapons program, owner of five patents for "weaponizing" anthrax. Patrick, who ran the offensive biological weapons program in the '60s at USAMRIID, says he wasn't approached until four months into the investigation. Feeling slighted, Patrick asked the FBI agent why it had taken so long. He says the agent replied, "Well, Mr. Patrick, you were a suspect." Patrick, 75, paused to digest that. "Well," he recalls telling the agent, "I suppose I was."
