February 22-27, 2002: Anthrax Attacks Suspect Ivins Submits Anthrax Sample to FBI Investigators

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).
