Most people did not know that the work in Ray Goehner’s materials characterization department at Sandia National Laboratories was contributing important information to the FBI’s investigation of letters containing bacillus anthracis, the spores that cause the disease anthrax. The spores were mailed in the fall of 2001 to several news media offices and to two U.S. senators. Five people were killed.
Sandia’s work demonstrated to the FBI that the form of bacillus anthracis contained in those letters was not a weaponized form, a form of the bacteria prepared to disperse more readily. The possibility of a weaponized form was of great concern to investigators, says Joseph Michael, the principal investigator for the project. This information was crucial in ruling out state-sponsored terrorism.
In fall of 2001, the FBI considered how to best investigate the anthrax letters. The agency convened two blue ribbon exploratory panels, and Sandia’s name came up during both panels for its expertise in electron and ion microscopies and microanalysis over the range of length scales from millimeters down to nanometers. The first spore material from the letters arrived at Sandia in February of 2002.
Sandia faced some uncertainty in working on this type of investigation. Researchers signed nondisclosure agreements and agreed to make themselves available to government agencies on short notice when called to give information.
