No cause yet in warehouse fire

Electrical system a focal point for investigators.

OAKLAND, CALIF. — Investigators said Tuesday that they still can’t pinpoint a specific cause in the fire that killed 36 partygoers in an Oakland warehouse.

They focused their investigation on electrical appliances plugged into the rear of the building where the fire started Dec. 2.

The electrical system is still part of the analysis of what sparked the fire, said Jill Snyder, the special agent in charge with the U.S. Bureau of Alcohol, Tobacco and Firearms.

“At this time, no final determination has been made,” Snyder said.

The ATF has finished collecting evidence, Snyder said. The Oakland Fire Department will prepare a final report for handover to prosecutors. Prosecutors have warned murder charges are possible as they determine whether crimes are linked to the blaze.

Alameda County District Attorney Nancy O’Malley said Tuesday the criminal investigation will be “thorough, methodical and calculated.”

The deadliest building fire in the U.S. in more than a decade broke out during a late-night dance party in the cluttered warehouse. The building had been converted to art studios and illegal living spaces, and former denizens said it was a death trap of piled wood, furniture, snaking electrical cords and only two exits.

After arriving at the warehouse a day after the fire, ATF investigators quickly ruled out arson and focused their investigation on the electrical system.

City and state officials fielded complaints for years about dangerous conditions, drugs, neglected children, trash, thefts and squabbles at the warehouse, raising questions about why it wasn’t shut down. Building department inspectors had not set foot in the warehouse for at least 30 years.

A firefighter with knowledge of the situation told The Associated Press last week that the warehouse’s address is not listed in an Oakland Fire Department database used to schedule annual inspections and was likely never checked for fire hazards.
