About 1,250 emergency workers raced against the clock to find survivors with drones, heavy equipment and sniffer dogs in the rescue and clean-up efforts, the California Governor's Office of Emergency Services said.
The latest victim, 87-year-old Joseph Bleckel, was found in his Montecito home on Friday, Santa Barbara County Sheriff Bill Brown said, adding that the remaining missing were between the ages of 2 and 30.
"We've got a window that's closing, but we're still very optimistic. There's been plenty of cases where they've found people a week after," Santa Barbara County Fire Department spokesman Mike Eliason said earlier on a muddy Montecito street especially hard-hit by the mudslide.
