March 31, 2005: Anthrax Attacks Suspect Ivins Is Questioned about His After Hours Laboratory Work in 2001

The FBI questions scientist Bruce Ivins about a marked increase in his after hours laboratory work from mid-August through October 2001 (see Mid-August-October 2001). Ivins tells investigators that he was working late at the time to escape troubles at home. The FBI is unable to find evidence of legitimate work Ivins performed during those visits. He is also asked to explain the differences in anthrax samples he submitted to the FBI in 2002 (see April 2002) and those seized in 2004 (see July 16, 2004).
