Park Fire in Northern California more than tripled in size in its 2nd day; arson suspect arrested: "We're shellshocked"

The Park Fire, one of many wildfires raging in Northern California, grew from a small brush fire in Chico to the largest blaze in the state in less than two days. A man suspected of starting the fire has been arrested.

The Park Fire started Wednesday afternoon in a park and grew from about 6,400 acres late Wednesday night to 45,550 acres Thursday morning, then more than tripled in size by Friday morning to 164,000 acres — some 256 square miles. Containment had been at 3%, but it fell to zero percent, according to Cal Fire.

"This fire has fingers that are growing in different directions depending on which way the wind is blowing," Butte County Sheriff Kory Honea said.

Cal Fire arson investigators have arrested a 42-year-old Chico man on suspicion of starting the blaze, Butte County District Attorney Mike Ramsey announced. Officials later identified the suspect as Ronnie Dean Stout II.

His arrest followed reports of a man seen pushing a burning car into a gully at around 3 p.m. Wednesday in the upper part of Bidwell Park, where the blaze broke out, the district attorney said. The car slid 60 feet down an embankment and went up in flames completely, sparking the Park Fire.

Ramsey said the man was then seen calmly leaving the area among other residents who fled as the fire rapidly grew. A local judge issued an arrest warrant Thursday morning, and Stout was booked into the Butte County Jail, where the warrant stipulated he would be held without bond until his arraignment on Monday.

Authorities in Butte County and neighboring Tehama County issued numerous evacuation orders and warnings as the Park Fire developed,. Shelters were set up for people and for animals impacted by the fire, and California Gov. Gavin Newsom's office said in a news release early Thursday that 3,500 people had already been evacuated from the area.

Officials said Friday morning that 134 structures have been destroyed in the blaze. CBS Sacramento has captured footage of several homes that were lost.

"We're shellshocked right now," she told CBS News' Jonathan Vigliotti, who was with her as she returned for the first time. "It really is surreal." Yarbough is a former news anchor for Action News Now, a CBS affiliate in Chico. She was also an anchor and reporter for KCBS in Los Angeles.

Newsom announced that the state received a grant from Federal Emergency Management Agency to bolster California's response to the fast-moving blaze. The U.S. Department of Homeland Security confirmed that the grant had been issued.

Homeland Security said roughly 1,100 homes in and around the towns of Eco, Richardson Springs and Cohasset, all within Butte County, were directly threatened at the time the agency received Newsom's request for assistance — which was before its size increased seven-fold. Those three towns alone are normally home to a population of about 10,000 people, the department said.

Cal Fire said more than 1,153 personnel were fighting the blaze.

The Park Fire is currently the largest, but far from the only, wildfire burning in California. And farther north, in Oregon, the.
