Soon after September 11, seven anthrax-laced letters killed five people, injured 17 and stoked fears of a new wave of terror. Steven Hatfill was publicly identified as a “person of interest” in the case. The FBI took reporters along when they raided his home. Since then the government settled lawsuit the government scientist brought for $5 million. Now, the focus is on Bruce Ivins, who also worked at the Army's biological research lab at Fort Detrick, Maryland. Ivins allegedly committed suicide last week because he learned he was about to be indicted. Although the FBI is about to close the case, not everybody is satisfied that the evidence is all in.
