Ivins works at USAMRIID, the US Army’s top bioweapons laboratory, and is helping with the anthrax investigation even though the FBI has reason to believe the anthrax could have come from USAMRIID (see Mid-October 2001 and Winter 2001). Ivins is using a variety of the Ames anthrax strain known as RMR-1029. A subpoena dated February 22, 2002 is issued to Ivins and other scientists, telling them to submit samples of their anthrax. Ivins submits his sample on February 27, apparently before he receives the subpoena. He is the only scientist to submit a sample before getting the subpoena. He had been discussing with investigators what kind of protocol to use for the samples, so he is familiar with the desire for the samples and how to submit them, but he does not completely the protocol with his sample. The FBI will soon destroy the sample he submits because it has not been prepared using the protocol, which is necessary for it to be used as valid evidence in trial. In April 2002, Ivins will submit a second anthrax sample. Around 2004, scientists will discover some unique genetic markers to the anthrax used in the 2001 attacks and will start comparing that anthrax to other anthrax. No match will be found between Ivins’s April 2002 sample and the anthrax used in the attacks. However, Paul Keim, a biologist at Northern Arizona University and an expert at distinguishing various strains of anthrax, keeps duplicates of all the anthrax samples sent to the FBI. In early 2007, it will be discovered that he still has a copy of Ivins’s February 2002 sample. A match will be discovered between that RMR-1029 sample and the sample from the attacks (see Early 2007). However, at least 100 scientists had access to this sample (see Late 2005-2006).

In February 2002, scientist Bruce Ivins submitted a sample of the anthrax he has been using to FBI investigators, but it was destroyed because it was not submitted according to strict protocols. As a result, he is asked to submit a second sample in April 2002, and does. Ivins works at USAMRIID, the US Army’s top bioweapons laboratory, and is helping with the anthrax investigation even as the FBI has reason to believe the anthrax could have come from USAMRIID (see Mid-October 2001 and Winter 2001). Ivins is using a variety of the Ames anthrax strain known as RMR-1029. Around early 2004, scientists will discover some unique genetic markers to the anthrax used in the 2001 attacks and will start comparing that anthrax to other anthrax. No match will be found between Ivins’s April 2002 sample and the anthrax used in the attacks. As a result of this discrepancy, the FBI will raid Ivins’s lab in July 2004 and seize more samples of RMR-1029 (see July 16, 2004). Additionally, Paul Keim, a biologist at Northern Arizona University and an expert at distinguishing various strains of anthrax, keeps duplicates of all the anthrax samples sent to the FBI. In early 2007, it will be discovered that he still has a copy of Ivins’s February 2002 sample. A match will be discovered between that RMR-1029 sample and the sample from the attacks (see Early 2007). However, at least 100 scientists had access to this sample (see Late 2005-2006). [New York Times, 8/20/2008] It remains unknown if Ivins altered the sample he submitted. Keim will later say that the genetic markers found in other samples of RMR-1029 should have been found in Ivins’s sample. He will note that “the FBI is implying he did it on purpose.” However, he will say that “Ivins may simply have failed to collect a representative sample.” [Philadelphia Inquirer, 9/1/2008] In an August 2008 press briefing (see August 18, 2008), a government official will be asked if the sample submitted was not RMR-1029. The official will reply, “I don’t want to speculate that far.” [US Department of Justice, 8/18/2008]

Jacques Ravel.Jacques Ravel. [Source: New York Times / Brendan Smialowsk]In 2002, scientists mapped the anthrax genome in an attempt to generate new leads for the anthrax attacks investigation. Initially, the results are disappointing because the anthrax used in the letters, which is from the Ames strain, do not seem to differ in any way from the original Ames strain used in many laboratories (see Early-Late 2002). But around early 2003, an unnamed US Army microbiologist at USAMRIID, the US Army’s top bioweapons laboratory, makes a breakthrough. He discovers a morph (also known as a morphotype) that allows scientists to detect differences between the genetic structure of the anthrax used in the attacks and other anthrax. Jacques Ravel, a leading member of the scientific team at the The Institute for Genomic Research (TIGR) that is decoding the anthrax genome, is asked to decode more morphs. After two years, the team is able to decode a total of eight morphs. The head of TIGR will later comment that it was not clear why the FBI did not ask other laboratories to share the task and speed up the process. Other scientists working with the FBI select four of the morphs as having the most reliable unique genetic differences, known as indels. All of the anthrax letters used anthrax containing these four indels. The FBI finally has a unique signature for the anthrax used in the attacks and starts looking for laboratories that have used an exact match. [New York Times, 8/20/2008] Apparently, by early 2004 scientists already know enough to notice a discrepancy with a sample scientist Bruce Ivins has submitted to the investigation, and the FBI raids Ivins’s lab in July 2004 to seize more samples from him (see Early 2004 and July 16, 2004).

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).

After years of work, by 2005, a scientific team working with the FBI has identified four genetic markers, known as indels, that make the anthrax used in the 2001 anthrax attacks unique (see Early 2003-2005). The anthrax is from the Ames strain, and the FBI has been slowly building a repository of 1,070 Ames anthrax samples from around the world. By late 2005 to 2006, it is discovered that only eight samples match the anthrax used in the attacks. Seven of these eight samples come from USAMRIID, the US Army’s top bioweapons laboratory, and the eighth sample comes from another unnamed laboratory in the US. One of these samples is the ancestor of all eight, and this is a flask known as RMR-1029 kept by USAMRIID scientist Bruce Ivins (see Early 2004). The FBI soon determines that about 100 scientists had access to this flask and its seven descendants. Investigators begin a new phase, using traditional criminology techniques to narrow down the possible suspects. [New York Times, 8/20/2008]

Paul Keim.Paul Keim. [Source: Public domain]The FBI matches an anthrax sample submitted by suspect Bruce Ivins with the anthrax used in the 2001 attacks. The sample, of anthrax used by Ivins in his work, was submitted to the FBI in February 2002, but the FBI then destroyed it since it had not been prepared using a strict protocol needed for it to be used as evidence in a trial (see February 22-27, 2002). By late 2006, the FBI suspects Ivins sent the 2001 anthrax letters (see Late 2006). Also in 2006, scientists have discovered unique genetic markers in the anthrax used in the 2001 attacks and they are comparing them to other anthrax samples they have collected. A sample Ivins gave to the FBI in April 2002 does not match the anthrax in the letters. However, Paul Keim, a biologist at Northern Arizona University and an expert at distinguishing various strains of anthrax, has kept duplicates of all the anthrax samples sent to the FBI. In early 2007, Keim discovers that he still has a copy of Ivin’s February 2002 sample, known as RMR-1029, and it matches the anthrax used in the attacks. However, at least 100 scientists had access to this sample (see Late 2005-2006), if not 200 to 300 scientists (see 1997). [Frederick News-Post, 8/19/2008; New York Times, 8/20/2008]
