FBI did not analyze anthrax from biodefense lab
Researcher Bruce Ivins in 2002 confessed to cleaning up the office contamination without telling anyone during an Army investigation at the U.S. Army Medical Research Institute of Infectious Diseases at Fort Detrick, Md. Ivins became a suspect in 2005 in the mailings that killed five and sickened 17.
FBI investigators have not yet analyzed the genetic fingerprints of 25 anthrax samples supplied from the lab contamination investigation, says Vahid Majidi of the FBI's Weapons of Mass Destruction Directorate.
"They're still in my lab," says Paul Keim, a microbiologist at Northern Arizona University. Keim called the FBI's decision not to examine the contamination samples "weird" given the intensity of investigators' focus on biodefense researchers, which included polygraphs of Army institute researchers.
Keim, until June, retained duplicates of the FBI's repository of 1,070 anthrax samples collected from researchers worldwide after the mailbox attacks. Genetic fingerprints of those repository samples eliminated suspects other than Ivins by 2007, says FBI lab director Chris Hassell. [Mark Godsey]
