Results of Examinations:

The STR typing results from specimens Q5-1, Q8-1, Q9-1, and Q16-1 were compared to the STR typing results from specimen Q40/Q41 [submitted under FBI Laboratory Number 010904012 and reported in FBI Laboratory report dated April 2, 2002].

Deoxyribonucleic acid (DNA) isolated from specimens Q5-1 (swabbing from specimen Q5), Q8 (swabbing from flap area), Q9 (swabbing from flap area) and Q16-Q18 (swabbing from inside specimens Q16 through Q18) was subjected to DNA typing by the polymerase chain reaction (PCR) at the amelogenin sex typing locus and the nine (9) short tandem repeat (STR) loci of the AmpFlSTR® Profiler Plus™ ID PCR Amplification Kit.¹

Specimen Q3-1 (swabbing from specimen Q3) was subjected to DNA typing by the polymerase chain reaction (PCR) at the amelogenin sex typing locus and the nine (9) short tandem repeat (STR) loci of the AmpFlSTR® Profiler Plus™ ID PCR Amplification Kit.¹ No detectable DNA and/or STR typing results were obtained from specimen Q3.

It is noted that the above specimens were submitted for comparison purposes to be used as an alternate reference sample for DUANE LORIN WEBER; however, the DNA profiles obtained from specimens Q5-1, Q8-1, Q9-1 and Q16-1 do not satisfy the DNAAUI inclusionary reporting criteria and therefore may be utilized only for exclusionary purposes. It is also noted that the DNA typing results obtained from specimen Q5-1, Q8-1 and Q9-1 indicate the presence of different source individuals. Based on the STR typing results, specimens Q5-1, Q8- 1, Q9-1 and Q16-1 are excluded as potential contributors of the DNA obtained from specimen Q40/Q41.

No other nuclear DNA examinations were conducted.

Evidence item designation: Q19, described as Glasses (1B1). Introductory statement noting this report supplements a prior FBI Laboratory report from April 2, 2002. FBI DNA analysis results comparing specimens Q5-1, Q8-1, Q9-1, and Q16-1 to specimen Q40/Q41 (FBI Lab Number 010904012). DNA was extracted and STR typing performed. Specimen Q3 yielded no detectable DNA. Specimens were submitted as an alternate reference for Duane Lorin Weber but did not satisfy DNAAUI inclusionary criteria and may only be used for exclusionary purposes. Multiple source individuals were indicated. All tested specimens were excluded as contributors to Q40/Q41 DNA. Footnote listing the nine STR loci included in the AmpFlSTR Profiler Plus ID PCR Amplification Kit. Page numbering (page 2 of 3) and document tracking number. Struck-through classification marking indicating 'For Official Use Only' status has been removed. Case reference identifier for the DB Cooper file.
