Hollywood publicist Ronni Chasen was shot from another car, possibly an SUV, not from the street or sidewalk. Though there are still no suspects and no motive for the murder, police believe Chasen was shot through her passenger-side window from another vehicle. Chasen was shot to death while driving her Mercedes-Benz in Beverly Hills early Tuesday morning on her way home from a movie premiere after-party. Beverly Hills Mayor Jimmy Delshad says police are working 24 hours a day on the case. A source also told The Hollywood Reporter that the murder was planned.
