Anthrax Mystery

I wonder what the story is?:

WASHINGTON (AP) - A top U.S. biodefense researcher apparently committed suicide just as the Justice Department was about to file criminal charges against him in the anthrax mailings that traumatized the nation in the weeks following the Sept. 11, 2001, terrorist attacks, according to a published report.

The scientist, Bruce E. Ivins, 62, who worked for the past 18 years at the government's biodefense labs at Fort Detrick, Md., had been told about the impending prosecution, the Los Angeles Times reported for Friday editions. The laboratory has been at the center of the FBI's investigation of the anthrax attacks, which killed five people.
