Dr. Lakshmanan Sathyavagiswaran, Los Angeles County's Chief Medical Examiner and a physician board-certified in six specialties, was called by the prosecution to provide expert testimony on the autopsy findings for both Nicole Brown Simpson and Ronald Goldman. His examination spanned nine days in June 1995 — one of the longest stretches for any witness — as prosecutor Brian Kelberg methodically walked him through wound analysis, time-of-death evidence, and the errors and omissions made by Dr. Irwin Golden, who had performed the original autopsies. Sathyavagiswaran occupied an unusual dual role: shoring up the prosecution's forensic case while simultaneously acknowledging the shortcomings in his own office's work, a tension the defense exploited when Robert Shapiro cross-examined him.
