Shawn Chapman was an attorney in Johnnie Cochran's law firm who served on the defense team throughout the criminal trial, handling witness examinations and motions across key phases of the case. She conducted the direct and cross-examination of Susan Silva and participated in cross-examinations on evidence handling and the testimony of Rosa Maria Lopez. Chapman also engaged in significant procedural battles, including a Brady motion discussion and arguments over the admissibility of testimony and videotape use in closing arguments — the kind of behind-the-scenes legal work that shaped what the jury ultimately saw and heard.
