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 a verdict expected Thursday.

• Officer Guzman's testimony undermined evidence custody: he made assumptions about vehicle inventory without visual verification and failed to maintain constant surveillance of the Bronco.
• EDTA battle resolved with plaintiff expert Lee testifying that trace signals were instrument contamination, not blood-tube markers, directly refuting the defense contamination theory.
• DNA expert Popovich faced sharp cross-examination revealing $30k plaintiff billing versus $5k civil billing disparities and anomalous control strip results.
• FBI photograph expert authenticated Flammer photos of Simpson in Bruno Magli shoes; defense attempted commercial-motive challenge but largely stipulated to shoe identification.
• Both plaintiffs and defense rested their entire cases; jury excused until Tuesday for closing arguments.
