FBI Focusing on 'About Four' Suspects in 2001 Anthrax Attacks.
The FBI has narrowed its focus to "about four" suspects in the 6 1/2-year investigation of the deadly anthrax attacks of 2001, and at least three of those suspects are linked to the Army’s bioweapons research facility at Fort Detrick in Maryland, FOX News has learned.
"Fort Detrick is run by the United States Army. It's the most secure biological warfare research center in the United States," a bioterrorism expert told FOX News.
