Exclusive: New Photos of Anthrax Suspect’s Lab

Investigators never found any traces of the attack anthrax in Ivins’ office, but they later discovered that he had sampled and cleaned his office and other areas following the attacks. We reported on questions surrounding the unauthorized cleanings and the Justice Department’s assertion that they were evidence of Ivins’ “guilty conscience.”

Ivins’ locker — #10 — is on the far left. Researchers would change in the locker room before entering the hot suites, the sealed rooms where they worked with the deadly agent.

This is Ivins’ secure BSL-3 hot suite lab at USAMRIID, where he maintained the RMR-1029 flask of anthrax spores — which the FBI alleges was the parent material of the 2001 anthrax attack powder — and where the FBI alleges he created the deadly anthrax powder that was sent though the mail beginning in September 2001.

The lyophilizer, or freeze dryer, which the FBI says Ivins could have used to make the attack anthrax. Stored outside of the secure BSL-3 hot suite, the lyophilizer was a central focus of the investigation; however, the FBI was never able to definitively link it to the attack anthrax, and some of Ivins’ colleagues are skeptical that he would have risked drying anthrax outside of the secure suite.

The FBI alleges that the powdered anthrax spores used in the attacks originated from this flask labeled RMR-1029, which was controlled by Ivins. But our investigation raised questions about the FBI’s analysis of samples taken from RMR 1029, and a report from the National Academy of Sciences claimed the FBI’s analysis “did not definitively demonstrate” that RMR-1029 spores were used to create the attack anthrax.
