Pressure Grows for F.B.I.’s Anthrax Evidence
By SCOTT SHANE and NICHOLAS WADE
NYT
WASHINGTON — After four years of painstaking scientific research, the F.B.I. by 2005 had traced the anthrax in the poisoned letters of 2001 to a single flask of the bacteria at the Army biodefense laboratory at Fort Detrick, Md., according to government scientists and bureau officials.
But at least 10 scientists had regular access to the laboratory and its anthrax stock — and possibly quite a few more, counting visitors from other institutions, and workers at laboratories in Ohio and New Mexico that had received anthrax samples from the flask at the Army laboratory.
To get that far, the Federal Bureau of Investigation had helped invent what was virtually a new science, microbial forensics, the use of biochemical clues to track a germ weapon to its source.
The bureau sponsored research at a score of government and university laboratories intended to estimate the age of the anthrax, tracing the water used to grow it, assessing how it was made into an inhalable powder and, perhaps most important, taking its genetic fingerprint.
But at that point, the science had largely reached its limits. To figure out who in the narrowed pool of scientist-suspects was the perpetrator, the F.B.I. would have to rely on traditional gumshoe investigative methods: interviewing colleagues and family members, searching houses and cars, doing surveillance, and assessing personalities.
