Across two brisk days in February 1995, Denise Brown took the stand in one of the most infamous murder trials in U.S. history. Denise's sister, Nicole Brown Simpson, was dead; Nicole's ex-husband, O.J. Simpson, was accused of murdering her. Witnesses came out of the woodwork testifying to O.J.'s alleged abuse, but it didn't seem possible to Brown. There was no way her strong, vibrant sister had been a battered woman. She believed this, even as she testified to an incident in which Simpson, after hurling Nicole into a wall, physically threw both Nicole and Denise out of the house and onto the sidewalk.
