Pacific Gas & Electric Co. shares plummeted 10.5 percent after state regulators directed the company to preserve any evidence of failed poles, conductors or other equipment that might be connected to Northern California wildfires that killed 32 people and reduced entire neighborhoods to rubble.

The steep one-day fall Friday means the value of the giant utility, or market capitalization, dropped about $3.5 billion, from $33.1 billion to $29.6 billion.

California fire officials are investigating downed power lines and other utility equipment as possible causes of massive wildfires that have destroyed at least 5,700 homes and businesses.

The California Public Utilities Commission also directed the utility to tell employees and contractors to preserve emails and other documents related to potential causes of the fires.

Fire officials say about 5,700 homes and buildings have been destroyed by wildfires burning in Northern California.

California Forestry and Fire Protection spokesman Daniel Berlant gave the new number Friday afternoon for the damage done since Sunday night by more than 20 wildfires burning mostly in the state's wine country.

The figure is up 2,200 from the 3,500 destroyed homes and buildings previously announced.

The blazes have also driven 90,000 people from their homes and killed 32 people.

California officials say it will be weeks before they determine the causes of the wildfires sweeping the state.

Ken Pimlott, the state's fire chief, said Friday that 20 investigators alone are in Sonoma County looking into the cause and origin.

He says the process is very technical and painstaking, and investigators won't have information to disclose for "weeks to come."

Part of the problem is that much of the evidence was consumed in the fires. That means investigators must look for other clues to decide what happened.

They are not yet ready to say whether any were caused by downed or sparking power lines from the strong, gusty winds that plagued the state overnight Sunday into Monday.
