32 homes are made uninhabitable by the blaze

Investigators are working to determine what cause the fire

CNN  — 

A fast-moving wildfire swept through Reno on Friday, killing at least one person and damaging up to 25 homes, officials said.

The Caughlin Fire in Reno burned 1,935 acres before firefighters contained the blaze, said Sierra Fire Protection District Chief Mike Brown, the incident commander.

The blaze has made 32 homes uninhabitable and damaged five, but is no longer a major threat to other structures, said Reno Fire Chief Michael Hernandez.

The cause of the fire remains unknown, but the fire chief said his department has ruled out that the blaze started at a homeless encampment or that teenagers seen in the area were responsible.

Investigators believe – though have not confirmed – that high winds caused electrical arcing on a power line, which sparked the fire, Hernandez said.

The city of Reno, the rest of Washoe County and Nevada all declared states of emergency Friday morning due to what’s being called the Caughlin Ranch Fire, the governments announced on their websites.

The fire was reported shortly after midnight Thursday, spreading within an hour and becoming a three-alarm blaze, Hernandez said.

The blaze had ballooned to 2,000 acres within about 12 hours, destroying some structures and causing minimal damage to others, according to the fire chief. He estimated that firefighters had saved 4,000 to 4,500 homes by Friday.
