Lost person Emily Thompson last seen at the beach in Santa Barbara wearing a blue sundress and wide-brimmed straw hat.

My sister, Emily Thompson, disappeared while we were enjoying a day at the beach in Santa Barbara. She was last seen wearing a blue sundress and a wide-brimmed straw hat. We had gone for a swim, but when I looked for her afterward, she was gone. We're really worried about her; please contact me if you have any information.
