, FD-302a'(Rev. 10-6-95) 27 9A-WF-222936-USAMRIID Continuation of FD-302 of Bruce E. Ivins ,on 09/08 /2004 004 Page _ 8 laboratory who have grown spores: Ld eee IVINS explained a previous statement where he b7c had said that the Ames strain was determined to be "hot! lained that USAMRIID used the Vollum 1B strain until showed some vaccine resistant strains in guinea pigs, one of which was the Ames strain. Therefore, .researchers decided to use the Ames strain instead of Vollum 1B. This occurred in the early to mid-1990s. IVINS was shown a series of photographs of samples collected by sat from IVINS on June 6, 2004. He was shown a photo of a tube labeled "Ames Stock, written in blue ink. IVINS did not recognize the handwriting on the tube. IVINS was asked why he called _ the sample a sample when the date on the tube was 1999 and IVINS stated that the tube was just in a box labeled and that may know more about this sample. IVINS was then shown a photograph o a tube labeled "Ames Spores, 2433, CDC 7738",_written in black ink. IVINS explained that this was a sample thatL__— got from IVINS and IVINS believes that the FBI already has this sample in the FBI The sample is either RMR 1029 or material that IVINS suggested the interviewing agents contact to determine what seed stock was used to make_this sample, did make this sample for IVINS was then shown fwo photos of a sample labeled "Ames Spores, written in green ink. IVINS did not recognize these tubes. IVINS was also shown a photo of a tube labeled "Ames Spores, Renograffin Purified, 3/28/01, 7739C", written in blue ink. IVINS noted that this was a sample of Ba prepared by[___ Jin March of 2001. He did not know the seed stock used to make this sample. The interview was then paused for lunch. After conducting some research during the lunch break, IVINS provided agents with copies of page 70 from notebook # 4010 and page 86 from notebook # 3655. In addition, IVINS provided agents with a one page document titled "Information on B. anthracis Ames spore lots", and a one-page document titled "Spore Preparation Form". These documents are maintained in an FD-340 in the 1A section of the file. From these documents, IVINS noted that the Ames spores sent to Dugway in 1997 were sent in suspension, in four 1mL polypropylene tubes, at a concentration of 1 x 10*° spores per mL. This shipment is consistent with IVINS sending RMR 1030 to Dugway in 1997. Although IVINS isn't sure that it was RMR 1030 that he sent to Dugway, the concentration of the 1997 shipment, the storage container, and the method of shipment are all consistent with RMR 1030 being sent to Dugway in 1997. IVINS noted that all of RMR
