According to the Washington Post, FBI investigators used DNA fingerprinting to analyze the 2001 anthrax samples and to trace them back to their original lab. The investigators identified unique sections of the anthrax genome and worked their way back to Fort Detrick. The Washington Post points out that it is unclear how the federal investigators went from examining anthrax DNA to Bruce Ivins, the researcher who committed suicide last week, as a number of other scientists in the lab also had access to the samples.
