Officer Robert Riske was an LAPD officer identified in the record as the first officer on the scene at 875 South Bundy Drive, where he discovered the victims and helped secure the location. His testimony extended across multiple days of direct, cross, and redirect examination in the criminal trial, and he was also examined during the civil trial. Riske testified that he notified supervisors and other officers, reported the visible evidence, and was directed with Officer Wally to search the residence; his partner was sent to secure the rear while another officer began setting up crime-scene tape. On cross-examination, defense counsel questioned him about his ungloved use of the residence phone, items he did not see photographed or fingerprinted, officer movements, scene preservation, and evidence handling, while the prosecution later emphasized his limited patrol role and used photographs to address movement of the glove and envelope.
