Natalie Singer testified for the defense as part of its systematic effort to impeach Detective Mark Fuhrman's credibility. Called by F. Lee Bailey, she recounted an encounter with Fuhrman from September 1987, when she was a recent arrival to Los Angeles living in a Beverly Hills–adjacent apartment. Her testimony, alongside that of Kathleen Bell and others, helped establish a pattern of openly racist attitudes and slurs by Fuhrman spanning nearly a decade — evidence the defense used to undermine his reliability as a key prosecution witness.
