A two-paragraph article in today’s NY Times, sans byline, appears to end discussion of the so-called “chemical signature” said to identify the source of water used to grow the anthrax letter spores:
On Tuesday at an American Society for Microbiology conference in Baltimore, an F.B.I. scientist, Jason D. Bannan, said the water research ultimately was inconclusive about where the anthrax was grown. An F.B.I. spokeswoman, Ann Todd, said on Wednesday that the bureau “stands by the statements” of Dr. Bannan.
It is a postscript to Scott Shane’s major article on Bruce Ivins dated January 4, 2009, which reported that a “chemical signature” of the water in which spores were grown pointed to Fort Detrick, Md.
