The list of 'missing' is up to 1,276. However there are serious problems with how the list is being compiled. From the article:
Among those who had been found but were still listed as unaccounted for was Suzanne Heffernan’s mother, Shirley Woodhouse. Heffernan had spoken with her parents as they evacuated their home in Paradise a week earlier, and she and her four siblings had been in close contact about their parents’ welfare ever since.
