An unidentified woman in her 50s was killed as she ran across a downtown intersection carrying an armload of laundry. The woman, who had just come from a nearby self-service laundry, was struck by a van as she crossed the intersection of Central Avenue and 24th Street against a red light, Los Angeles police said. The woman carried no identification. She is described as Latino, about 5 feet, 3 inches tall and 130 pounds. She was wearing a pink dress. Investigators said they believe she lived nearby because she left more of her washing, including children's clothes, in the laundry. The driver of the van was not cited.
