Dr. Irwin Golden, a Los Angeles County deputy medical examiner, performed the original autopsies on Nicole Brown Simpson and Ron Goldman and testified about the wounds during the July 8, 1994 preliminary hearing. During the later trial, the prosecution announced that it would not call Golden; instead, Chief Medical Examiner Dr. Lakshmanan Sathyavagiswaran testified extensively and acknowledged roughly thirty errors in Golden's autopsy work while maintaining that none affected the conclusions about cause of death or the murder weapon. The defense highlighted the prosecution's decision not to call Golden.
