Deadly blaze kills partygoers in Oakland, Calif.

UPDATE: Investigators continue to search for evidence of a crime in a Oakland warehouse fire that has claimed the lives of at least 33 people, making it the most lethal building fire in the United States in more than a decade. According to authorities, the victims included a 17-year-old, as well as people from Europe and Asia and some over 30, said Alameda County Sheriff’s Sgt. Ray Kelly said. Officials had identified eight of the dead—at least seven of them using fingerprints, but told family members of the missing that they may need to use DNA for more difficult identifications. “When we started this investigation, if you had told us that you would have 33 victims, we wouldn’t have believed you,” Kelly said of the fire that broke out late Friday night. “I don’t know how many people are left in there.”

OUR EARLIER REPORT (12/03/16, 12:17 p.m.): At least nine people died in a fire that broke out during a party in an Oakland, Calif., warehouse late Friday night, according to fire officials. At least another 13 people are unaccounted for as of Saturday morning, according to Oakland Fire Chief Teresa Deloche-Reed. The fire started about 11:30 p.m., tearing through the building during an event featuring musician Golden Donna. Authorities told KTVU-TV approximately 50 people were inside the building, which houses a group of artists and their studios. Fire officials said the building had no sprinklers. “It was too hot, too much smoke, I had to get out of there,” Bob Mule, a photographer and artist who lives at the building and suffered minor burns, told the East Bay Times. “I literally felt my skin peeling and my lungs being suffocated by smoke. I couldn’t get the fire extinguisher to work.”
