The plaintiffs presented a comprehensive rebuttal case on the final day of testimony, with expert witnesses defending DNA reliability, EDTA test results, and photograph authenticity against defense attack. Following aggressive cross-examinations that landed points on control anomalies and billing disparities, both sides rested. The jury will hear closing arguments Tuesday, with the case expected to go to the jury Thursday.

• Officer Guzman acknowledged making assumptions on a vehicle report without visual verification and not maintaining an uninterrupted view of the Bronco.
• Plaintiffs' EDTA expert Lee attributed the trace signals to instrument carryover rather than tube-blood EDTA; on cross-examination, he acknowledged performing no testing himself and lacking details of Martz's procedures.
• DNA expert Popovich faced sharp cross-examination over a reported $30,000 prosecution fee versus $5,000 for the civil case and anomalous control-strip results.
• FBI experts testified that the Flammer photographs were unaltered and showed Bruno Magli Lorenzo-style shoes; the defense challenged the analysis, handling, and commercial motive, the McElroy price sheet was admitted, and the defense stipulated to the shoe identification.
• Both plaintiffs and defense rested their entire cases; jury excused until Tuesday for closing arguments.
