Exhibits 955 and 1117 — Andrea Mazzola blood-collection demonstration videotape
LAPD Scientific Investigation Division demonstration videotape dated April 4, 1995, showing Andrea Mazzola collecting bloodstain swatches from mock items. Identified as Exhibit 1117 in criminal proceedings and Defendants' Exhibit 955 in civil proceedings, it was used with competing commentary about her collection technique, including John Gerdes's asserted contamination events and Gregory Matheson's opinion that the depicted conduct did not affect evidence integrity.
