Early 2004: Conflict with Anthrax Samples Leads FBI Investigators to Bruce Ivins

Between 2003 and 2005, scientists working with the FBI’s anthrax investigation have been developing a system to compare the anthrax used in the 2001 attacks with other anthrax samples they have completed (see Early 2003-2005). By early 2004, the system apparently still is not complete, but scientists have discovered enough to focus their attentions on USAMRIID, the US Army’s top bioweapons laboratory (see Early 2004). They also note a discrepancy. In 2002, USAMRIID scientist Bruce Ivins had submitted a sample of a variety of the Ames anthrax strain known as RMR-1029 (see April 2002). The FBI had also collected some other samples of RMR-1029 from other scientists. All the samples of RMR-1029 had genetic markers that match the anthrax used in the attacks except for Ivins’s sample. As a result, in July 2004, the FBI will raid Ivins’s lab and seize more of his RMR-1029. These samples will also have the genetic markers matching the anthrax used in the attacks, raising more questions as to why the sample Ivins submitted does not (see July 16, 2004). (Flam 9/1/2008)
