Up to 40 feared dead in blaze at California party

The building in Oakland lacked permits for people to live and work as a group of artists did, and for the party to take place, officials said, adding that it also had no smoke detectors or sprinklers.

The interim chief of Oakland's Planning Department, Darin Ranelletti, said the city had recently received complaints against the building for debris and trash placed in adjacent vacant lots, and illegal construction inside the building.

Firefighters at the scene had to pull out of the building to shore it up when part of the fragile structure and some of the walls began to move. The roof eventually collapsed.

Nine bodies have been recovered so far. Sergeant Ray Kelly of the Alameda County Sheriff's department told an evening news conference that about two dozen people who were reported missing had been located. But at least two dozen more remain missing, he said. 

"We don't know how far into the process we are, because we don't absolutely have a number of people that we know are deceased inside of there," he said.

Most of those who perished in the blaze that started about 11:30 pm Friday were thought to have died on the upper floor of the two-story warehouse known as Oakland Ghost Ship, Oakland Fire Chief Teresa Deloach Reed said.

"It must have been a very fast-moving fire," she said. It was not immediately known what started the inferno atthe electronic dance music party attended by an estimated 50 to 100 people.

Some of the missing are from overseas, making identification of the victims -- thought to be in their 20s and 30s -- more difficult.

The warehouse had numerous partitions that had been added and a makeshift stairwell built from pallets. Some of the structural changes made it extremely difficult for people to escape, Reed said.

"There wasn't a real entry or exit path," Reed said. The clutter hampered firefighters' efforts to put out the blaze. "It was filled end-to-end with furniture, whatnot, collections," Reed said. "It was like a maze almost."

It appeared no smoke detectors were activated in the building, which also had no sprinkler system, she added. Friends and families of partygoers took to social media to search for news about their loved ones, with some posting information on the event's Facebook page.
