One minute, Jennifer Jones was stopping to help the victims of a one-vehicle crash she witnessed while driving on a Honolulu freeway. The next, she was a victim herself, after she says the driver of the wrecked SUV jumped into her car and sped off, leaving Jones on the side of the road with one of his injured passengers. Jones works part-time selling cosmetics and was on her way home from a Super Bowl-themed makeup event Sunday when the sport utility vehicle ahead of her started swerving erratically on the H-1 freeway. The SUV then crashed head-on into a concrete median.
