Daniel Petrocelli served as lead plaintiff attorney representing Fred Goldman in the civil case against O.J. Simpson. At an October 31, 1995 property-return hearing, he said he had entered the case about ten days earlier and described efforts to keep evidence in neutral custody until the civil litigants could inspect it and determine what required preservation. Across depositions and trial proceedings, Petrocelli examined Simpson and numerous witnesses, including Allen Cowlings, Brian “Kato” Kaelin, Robert Kardashian, and Marcus Allen; his questioning challenged Simpson's accounts of the June 12–13 timeline and prior statements, and Petrocelli asserted a minus-22 polygraph result that Simpson disputed by denying he had taken a polygraph. In closing argument, Petrocelli attacked Simpson's credibility and presented the plaintiffs' interpretation of DNA, shoe-print, hair, fiber, glove, sock, and domestic-violence evidence through a “what kind of man” rhetorical framework.
