A new FBI theory based on evidence recovered from a Maryland pond suggests how the person behind the 2001 anthrax attacks could have packed the deadly
spores into envelopes without being infected, The Washington Post reported Sunday.
Sources close to the case told the Post that the discovery in the ponds was so compelling that the FBI now plans to drain one of the ponds of
thousands of gallons of water for a detailed search this summer.
Law enforcement officials say the scientific analysis of the anthrax sent in letters that killed five people is consistent with the Ames anthrax
strain housed by the U.S. military at Fort Detrick and distributed to a number of labs for research.
