Lab Analyst Notes Testimony

179 items · 179 documentary · 104 with detail pages

This collection assembles bench notes, worksheets, sketches, reports, photographs, demonstrative boards, and prior testimony associated with evidence collection and laboratory examination. Records by or concerning Matheson, Yamauchi, Sims, Mazzola, Fung, Kestler, and other witnesses document such subjects as item numbering and transfers, sampling order, serology and DNA testing, laboratory layout, equipment, and examination chronology. Many materials were used to explain procedures or results, while others supported disputed questions about attribution, timing, documentation, contamination, degradation, security, or the interpretation of laboratory findings.
