CASE CLOSED … what really happened in the 2001 anthrax attacks?

* Meglumine and Diatrizoate were both detected in the USAMRIID RMR 1029 sample — but Meglumine and Diatrizoate were NOT detected in the 2001 letter spore evidence

    The former lead Amerithrax investigator recommends that FOIA requestors seeking exculpatory evidence should bear down on this issue in a request. I would make the request but Dave Hardy is much more impressed with requests from major media organizations.

    In the article published April 26, 2012, the authors summarize:

    “The purification of B. anthracis spores with products like RenoCal-76® has been previously reported to be an effective means of purifying spores (3,4); however, it is appropriate to mention that it is not considered the standardized approach. RenoCal-76®, Hypaque-76®, and other similar products have a clinical use in the radiographic imaging field and are not commercially available to research laboratories for the purposes of spore purification. The investigation determined that some laboratories conducting B. anthracis research, with the specific strain identified in the evidence, were using RenoCal-76® or similar products to purify spores. It was believed by the Amerithrax Task Force that trace levels of RenoCal-76®, or its primary components of meglumine diatrizoate and sodium diatrizoate, may persist on the outer spore surface. The primary objective of the work described in this manuscript was to develop and validate a sensitive and selective assay for the qualitative detection of meglumine and diatrizoate. Potential source information is always valuable in a forensic investigation. Although these results did not confirm the possible source of the spore material, they did indicate that the spore material used in the mailings was consistent with not being diverted directly from RMR-1029.”

      The implication of the study is that the mailed anthrax was made in a lab that DID NOT have commercial access to Renocal-76 or Hypaque-76.

      Given the first mailing had a lot of debris, the renocal or hypaque would not have been removed. Thus, its absence points strongly away from its use.

      It also tends to show that the dried powder that John Ezzell, the FBI’s anthrax expert, made out of Flask 1029 was not used in the anthrax mailings. (I credit that he used renografin because I found him to be forthright and courageous in coming forward to address these questions in a conference moderated by Mr. Weinstein. I had the pleasure of asking JE about these issues relating to his making a dried powder out of Ames supplied from Flask 1029. The conflict of interest that the FBI’s scientist had in throwing out Dr. Ivins’ February 2002 to Dr. Ezzell’s repository is off the charts. For the FBI to then concoct a way to use that throwing out as evidence of Dr. Ivins’ guilt — while withholding the documens about his work on the rabbits at the times in question — is morally abhorrent.

      That Dr. Ayman was able to hoist the USG on its own petard by using the “weapons of his enemy” — as directed by the hadiths — is a sad day for US intelligence analysis. Awlaki was coordinating with the scientist who shared a suite with the leading DARPA-funded researchers working with virulent Ames. If that wasn’t enough, Bruce Ivins supplied a former Zawawhiri associate virulent Ames and the FBI did not obtain the relevant documents until Spring 2005. His childhood friend consults with the CIA and explains that he was recruited by Dr. Ayman while at medical school

      Amerithrax represents the greatest intelligence failure in the history of the United States. The people with loved ones in Washington DC and NYC might want to get this one right.

    Take a moment and study this graphic and understand the FBI’s new article.

    No meglumine or diatrizoate was detected and thus there is no reason to think renocal or renografin was used.

    2/12/2003 Ivins 302 interview

    Double purified material needs to have a chromatogram done to determine whether it was run through a gradient. A trace of the gradient would remain on the material and should be indicated by a peak on the chromatogram. Some possible gradients include sucrose, hypaque, renografin (which became known as renocal but may not be manufactured any longer, or phycoll. [Note Ficoll apparently is meant.]

    Comment: None of the density gradients mentioned by Dr. Ivins included colloidal silica (i.e., Percoll).

      RenoCal-76 = Diatrizoate Meglumine

      and so, although I am not a scientist, I believe it can be inferred that RenoCal was not used to purify what was mailed.

      When did Dr. Ivins and his assistants start using Hypaque instead of Renocal-76?

      Is Hypaque consistent with what was observed in the testing? What do the NAS documents say?

      What did Dugway use? What did Battelle use?

      BRUCE: Please educate me a little – many of the older papers discuss
      “purification” of the spores with Renografin-76. Is this the same material
      as Hypaque-76 or can it be used as the same? If these are not
      interchangeable, do you know of a current source for the Renografin-76?
      Thank for your help

      – Yes, we used to use Renografin-76. The company stopped making it and started making Renocal-
      76 instead, so we began using that. Then Renocal-76 was taken off the market, so we began using
      Hypaque-76, which performs just the same as Renografin-76 and Renocal-76 as far as spore
      purification goes.
      – Bruce
