SAN FRANCISCO (AP) - San Francisco residents are mourning the passing of Vivian Brown - one of two twin sisters who had become local celebrities over the years by walking through the city's streets in matching high-end outfits, identical hairdos and cheerful smiles.

Barbara Farber, director of development for Jewish Family and Children's Services, told the San Francisco Chronicle that the 85-year-old Brown died in her sleep on Wednesday at an assisted care facility in the city.

Vivian's twin - Marian Brown - told The Chronicle in August that Vivian suffered from Alzheimer's disease, and that after a fall in July, had been admitted into doctors' care.

San Francisco Mayor Ed Lee issued a statement saying the city was "heartbroken by the sudden passing of Brown."
