The number of people killed in wildfires burning in California has risen to 50 -- including 48 from Northern California's Camp Fire, already the most destructive and deadly blaze in state history.
As firefighters battle that fire Wednesday in Butte County north of Sacramento, authorities fear more human remains will be found as searchers comb through rubble and ashes in Paradise, the ravaged town of about 27,000 residents.
"I want to tell you, though, this is a very, very difficult process," Butte County Sheriff and Coroner Kory L. Honea told reporters.
"There's certainly the unfortunate possibility that even after we search an area, once we get people back in there, it's possible that human remains can be found.
"Authorities have requested that 100 National Guard troops join cadaver dogs, mobile morgues and anthropology teams in the grim search and recovery of human remains.
In Southern California, firefighters still are battling the Woolsey Fire, which so far has left two people dead in Malibu.
They've also been fighting a new blaze, the Sierra Fire, in San Bernardino County.
It started late Tuesday about 50 miles east of Los Angeles near Rialto and Fontana, and by Wednesday morning had burned 147 acres, though no evacuations have been ordered, the San Bernardino County Fire District said.
