Authorities in Northern California say at least four people were killed by a wildfire burning in California's Sierra Nevada foothills, bringing the state's death toll to 29.
Yuba County Sheriff Steve Durfor confirmed Thursday that the four have died since a blaze ignited there Sunday night.
The fire is burning 100 miles (160 kilometers) north of several blazes in wine country that also broke out Sunday night and that have killed 25 people.
The blaze in the foothills has destroyed more than 100 homes and displaced 2,500 people.
Fire officials say it has charred 16 square miles (41 square kilometers) but fire crews overnight made significant progress and it's 45 percent contained.
Officials say recovery teams, some with cadaver dogs, will start searching for bodies in some areas devastated by wildfires raging in California wine country.
Sonoma County Sheriff Robert Giordano says officials are investigating hundreds of reports of missing people and that recovery teams will start doing targeted searches for bodies Thursday. He warns that identification may be difficult and take some time.
He says officials have found some bodies almost completely intact but other remains are "nothing more than ash and bones."
The Sonoma County Sheriff also noted that they've received over 900 missing persons reports, with roughly 463 still outstanding.
