Criminalist Andrea Mazzola's testimony dominated the day. On direct examination, Goldberg used videotape and records to address errors in her prior Griffen hearing testimony, collection timing, form erasures, item renumbering, and chain of custody. On cross-examination, Neufeld contrasted her prior answer that she collected the red stain on the Bronco and stains leading up the driveway with her current recollection that Fung collected items 4, 5, and 6; Mazzola said the current account was based on memory and denied that her later meeting with Fung influenced it. She also testified that she was a probationary employee with no crime-scene-processing experience before joining the LAPD.

• Mazzola testified she was called to prior hearing with no preparation, handed a colleague's notes as she entered the courtroom

• Cross-examination contrasted Mazzola's prior answer that she collected the red stain on the Bronco and stains leading up the driveway with her current recollection that Fung collected items 4, 5, and 6
• Mazzola agreed her current account that Fung collected items 4, 5, and 6 was based on memory rather than a document, photograph, or videotape she had seen showing him do so
• Mazzola acknowledged meeting with Fung after her August 1994 testimony to compare differing recollections of evidence collection, but denied that the meeting influenced her current recollection
• Mazzola testified that she was a probationary employee on June 13, had no crime-scene-processing experience before joining the LAPD, and considered herself a trainee in discretionary crime-scene viewing
• Testimony addressed missing initials on some coin envelopes, documentation inconsistencies, form erasures, and evidence-item renumbering
