Officials in Oakland say the death toll from a fire at a warehouse during a dance party has climbed to 33.
Alameda County Sheriff's Sgt. Ray Kelly announced the latest figure at a news conference Sunday. The number increased from 24 earlier in the day, as crews continued to comb through the charred building.
Oakland Mayor Libby Schaaf says prosecutors have launched a criminal investigation, but she did not provide specifics.
The fire ripped through a converted warehouse known as the "Ghost Ship" about 11:30 p.m. Friday during an electronic dance music party. Officials believe 50 to 100 people may have attended the event.
