Scientists Question Government's 2001 Anthrax Attacks Conclusion

Three scientists said they're preparing a research paper questioning the government's conclusion that an Army microbiologist at Fort Detrick in Frederick was the sole perpetrator of the 2001 anthrax attacks.

The paper is scheduled for publication next month in the Journal of Bioterrorism & Biodefense, Louisiana State University epidemiologist Martin Hugh-Jones said.

The article raises questions about the chemical composition of the anthrax that Hugh-Jones said must be answered before the case can be closed.

The head of a National Academy of Science committee that reviewed the FBI's work said the article points out connections that deserve further consideration.

A Justice Department spokesman said his agency stands by its findings that Bruce Ivins made and mailed the anthrax-filled letters that killed five people and sickened 17 others.
