The intensified effort to locate victims came on the sixth day of a blaze that incinerated over 7,000 homes and other buildings, including most of the town of Paradise in the Sierra foothills of rural Butte County about 175 miles (280 km) north of San Francisco. County Sheriff Kory Honea said 228 people were listed as missing, and his office also was conducting "well-being checks" on nearly 1,300 individuals whose loved ones had reported concern for their whereabouts. By Tuesday, the killer blaze dubbed the Camp Fire had blackened 125,000 acres (50,500 hectares) of drought-parched scrub and brush, up 8,000 acres from the night before, but crews had carved containment lines around nearly a third of the fire's expanding perimeter.
