LAPD Item 31 — Second Bronco Console Blood Swatch
LAPD item 31, the second blood swatch from the Bronco console. PCR testing left extract and one small square; testimony described mixed DQ-Alpha and D1S80 findings, while the certainty and interpretation of faint allele signals were disputed, including Gerdes's disagreement with Sims's analysis. Closing argument attributed additional PCR and RFLP conclusions to the item.
