The trial entered a new procedural phase as the People called Dr. Lakshmanan Sathyavagiswaran, LA County's Chief Medical Examiner, to provide expert testimony on autopsy evidence. After extensive credential-building, Sathyavagiswaran signaled he would evaluate the significance of mistakes Dr. Irwin Golden made in the original autopsies. A brief sidebar included a heated exchange over proposed jury instructions related to prior sanctions and an 'air-tight alibi' instruction, as well as the defense's request for Golden's performance records.
