The fire grew by nearly 20,000 acres to 142 square miles (368 square kilometers). The name of the firefighter killed in the nearby El Dorado Fire was being withheld until family members are notified. More than 7,900 wildfires have burned more than 5,468 square miles (14,164 square kilometers) in California this year, including many since a mid-August barrage of dry lightning ignited parched vegetation. The El Dorado Fire has burned more than 34 square miles (89 square kilometers) and was 59% contained, with 10 buildings destroyed and six damaged. ___Associated Press writer John Antczak in Los Angeles and Daisy Nguyen in San Francisco contributed to this report.
