A federal grand jury was preparing to indict a Maryland bioweapons expert for his role in the 2001 anthrax attacks that killed five people and terrorized the country, according to two sources familiar with the investigation.
Prosecutors were considering whether to seek the death penalty against Bruce E. Ivins, 62, who worked at an elite U.S. Army bioweapons laboratory in Fort Detrick. Ivins died Tuesday in an apparent suicide.
