An 11-year-old Mission Hills girl sitting in the bed of a pickup truck was killed when she was ejected and struck by another vehicle in the carpool lane of the Ronald Reagan Freeway, authorities said Monday.
The driver of the pickup truck, 38-year-old Maria Diaz of Lancaster, swerved to avoid hitting an object in the road Sunday night, then lost control and hit a median, said Officer Michael Curtin of the California Highway Patrol.
