One of the leading scientists in the investigation of the 2001 anthrax attacks has committed suicide after learning the FBI had identified him as a suspect in the attacks. Bruce Ivins, 62, had worked at a U.S. government biodefense labs in Maryland for eighteen years. He died after — no, not what you think — after ingesting "a massive dose of prescription Tylenol mixed with codeine," according to a friend and colleague. I did some reporting and actual lab work on bioterrorism after the attacks. Anthrax, I learned, isn't taken seriously as a weapon of mass destruction because it's hard to deliver lethal doses, and it's not rabidly contagious. You really want smallpox. (Photo by AP/Ron Thomas)
