FBI destroyed type of anthrax in attacks
WASHINGTON - FBI scientists early on had - but destroyed - the unique strain of anthrax used in the deadly 2001 attacks that years later would lead them to Dr. Bruce Ivins, the government's top suspect who committed suicide three weeks ago.
FBI Assistant Director Vahid Majidi said yesterday the initial anthrax sample that Ivins took from his Army lab in February 2002 and gave investigators did not meet court-ordered conditions for its preparation and collection.
In a briefing for reporters, Majidi said the sample kept at the FBI lab was destroyed because the bureau believed it might not have been allowed as evidence at trial.
The science that let investigators look for tiny genetic mutations in the kind of anthrax used in the attacks was only becoming available around 2004, Majidi said. Not until then did investigators trace strains of genetically-unique anthrax back to Ivins.
As part of a February 2002 subpoena, Ivins gave investigators two samples of the unique anthrax strain known as RMR-1029 that he created in his lab. One went to the FBI lab, where it was destroyed. The other went to the lab of Dr. Paul Keim, a geneticist at Northern Arizona University in Flagstaff, Ariz.
Keim still had his RMR-1029 sample in 2006 when the FBI realized it could match Ivins to two batches of anthrax-laced letters that were mailed in the weeks after the Sept. 11, 2001, terror attacks.
The anthrax letters killed five and sickened 17 after turning up on Capitol Hill, in newsrooms and postal facilities.
Ivins took a fatal dose of acetaminophen last month as prosecutors prepared to indict him for murder.
