Authorities announced Thursday night that the official death toll after Saturday's mudslide in Oso, Wash. had risen to 17, but warned that the total number of victims was likely to increase. The rescuers, many of whom are volunteers who hold other jobs, have vowed to remain at the site of the slide until they are no longer needed.
