Jonathan Fairtlough served as the prosecution's technical coordinator, responsible for operating the visual presentation equipment used throughout the trial. Marcia Clark introduced him to the jury during her opening statement, crediting him as indispensable to the team's ability to display exhibits and photographs. His role was primarily behind the scenes — calling out exhibit numbers like P-29, P-4, and P-7 as Clark narrated the prosecution's timeline — but his presence spanned dozens of trial days across witness examinations, motions, and closing arguments, making him a constant fixture of the prosecution's courtroom operation.
