USPlS\RJMuehlberger … Case No. – Lab File No. 9-957-002016
Type of Examination: Questioned Documents
Request Date(s) 1/2007
SA FBI Washington Field Office
7799 Leesburg Pike
Falls Church, VA 22043
Determine whether or not the questioned entries appearing in the printed digital images (also contained on CD) of three labels; one depicting the writing “Ames strain RMR from Dugway Bruce Ivins (1997) 2/27/02” and two depicting the writing “Dugway Ames spores – 1997” were written by Bruce E. Ivins, whose known writings are depicted in the photocopies of various course of business documents.
Determine whether or not the questioned entries appearing on the “anthrax” envelopes and letters (photographic copies retained in the laboratory) were written by Bruce E. lvins, whose known writings are depicted in the photocopies of various course of business documents.
Bruce E. Ivins probably wrote the original of the questioned entries appearing in the printed digital images of the three labels described above.
Bruce E. Ivins probably wrote the original of the questioned address entries appearing in the printed digital images of the two parcels.
Bruce E. Ivins probably did not write the writings appearing on the “anthrax” envelopes and letters.
The qualified findings expressed above are due to the lack of original documents from which the examination and comparisons were conducted. The submission of the original questioned and known writings could provide for more definitive findings. In addition, the
submission of known exemplars reflecting the writings appearing on the “anthrax” envelopes and letters would need to be examined prior to fully eliminating Bruce E. Ivins as the writer of these questioned writings.
The request for examination was submitted by FBI Special Agent (name redacted) under their File Nos. 279A–WF-222936-LAB and 279A-WF-222936-SC 24. This examination is also in reference to U. 8. Inspection Service Case No. I.
EXHIBITS: The exhibits described in this report of examination, with the exception of the photographic copies of the letters, were hand carried to the laboratory by FBI Special Agent on January 11, 2007. All submitted exhibits are returned with this report.
