Butte County Sheriff Kory Honea told reporters at a Thursday afternoon news conference that search crews had recovered eight more bodies in the burn area.
The number of people unaccounted for rose to 1,011, up from 631 on Thursday evening, after authorities combed through additional 911 calls, emails and other reports generated at the peak of the chaotic evacuation.
Honea said that number may include some people who are counted twice or others who may not know they were reported missing.
The Camp fire is by far the worst wildfire in recorded California history. By Thursday evening, the blaze had chewed through 141,000 acres and 11,862 structures, destroying an entire town in hours. Officials said it could take weeks to complete the search for victims. Thousands of survivors are without homes, living in shelters and tent cities.
