The prosecution completed its examination of Officer Riske and introduced Sergeant Rossi, the watch commander who coordinated the initial crime scene response. The defense methodically dismantled both witnesses' testimony through cross-examinations by Cochran and Bailey, exposing systemic failures in evidence preservation, scene contamination from unauthorized personnel walkthroughs, and delayed notification of O.J. Simpson. A motion hearing erupted over evidence access and EDTA testing protocols, with the judge ordering accelerated FBI testing.

• Cochran's cross-examination of Officer Riske detailed multiple evidence preservation failures: Akita's blood-stained paws never examined, no interior crime scene photographs taken, Jeep never dusted, and Fuhrman entered Goldman's body area without protective gear.
• Clark's redirect attempted to rehabilitate Riske by clarifying that patrol officers' role was limited to securing the scene and notifying detectives, not collecting evidence or directing photographers.
• Sergeant Rossi testified about his role as watch commander, describing the notification chain, scene perimeter verification, and his observations of the black glove and dark cap near the victims' bodies.
• F. Lee Bailey's cross-examination of Rossi exposed three critical failures: inadequate scene security verification, multiple officers walking the crime scene before forensics arrived and potentially destroying footprint evidence, and the failure to promptly notify O.J. Simpson of his ex-wife's death.
• A contentious motion hearing focused on the prosecution's plan to conduct EDTA testing before releasing evidence to the defense, with Judge Ito ordering the prosecution to accelerate FBI testing from February 27 to the end of the week.
