Officials used rapid DNA analysis and dental analysis to positively identify the victims, the tweet said. The fire started in late July and has burned more than 60,000 acres, destroying nearly 185 structures, including 90 homes, in northern California. The massive wildfire is burning in forests near the California-Oregon border and is the largest fire in California so far this year. As of Saturday, the fire was 95 percent contained, according to the California Department of Forestry and Fire Protection. In addition to the four deaths, 12 people were injured during the fire, the department said. Firefighters with 948 personnel continue to battle the flames, locating and extinguishing remaining hot spots and removing dangerous trees. All evacuation orders within the fire’s footprint were lifted Thursday, according to a tweet from the official Klamath National Forest account, though “there is still a significant threat of toxic materials and debris.” California’s persistent drought set the stage for the fire’s rapid spread, officials said. High temperatures and low humidity combined with dry storms allowed the flames to quickly spread across thousands of acres.
