There is a very coordinated push to leak details about the late Bruce Ivins to certify that he is the "lone nut" anthrax killer, details which don't entirely hold up upon scrutiny. There's definitely a desire on the part of the government to make this an open and shut case seven years after the fact, but it doesn't completely hold together. In fact, the media reports are almost all contradictory.
The LA Times is claiming that Ivins stood to make money off of an anthrax panic, because he invented some bioterror vaccines, but inside the article it's made clear that we're talking about not much more than $10,000. A social worker who worked as a therapist with Ivins was reportedly scared to death of him and claimed that he tried to poison people in the past, but the social worker, Jean Duley, has her own checkered past, with a long rap sheet, and apparently knew about the grand jury investigation, as it's in her restraining order against Ivins:
