LOS ANGELES (AP) — It’s been more than three years since the arrest of eccentric New York real estate heir Robert Durst in the execution-style shooting of his best friend years earlier in Los Angeles. Prosecutors could move closer to bringing him to trial if they can show probable cause at a hearing that begins Monday that Durst killed Susan Berman in order to silence her from revealing what she knew about the death of the multimillionaire’s first wife. Durst, 75, has pleaded not guilty, and with all that has emerged about him publicly from an HBO documentary series and from a string of unusual court hearings that have already taken place, it seems likely a Los Angeles Superior Court judge will order the case to proceed to trial. Prosecutors have started recording testimony over the past year of older witnesses who might not be available if there is a trial. Some of the testimony includes damning evidence for Durst, who already has beaten a murder rap in an unrelated 2003 Texas killing.
