ESCONDIDO, Calif. -- Firefighters are struggling to control six fast-moving wildfires burning across a huge part of Southern California. The first death linked to the fires was confirmed Friday night. More than 1,000 buildings and homes have been destroyed and the fires have burned 260 square miles -- bigger than the size of Chicago.

From Santa Barbara to San Diego, some 8,700 fire fighters are slowly increasing the containment on these blazes. The Lilac Fire in San Diego County erupted on Thursday and exploded within hours, but firefighters caught a break on Friday when the winds died down, CBS News correspondent Carter Evans reports.

The largest most destructive blaze, the Thomas Fire in Ventura County, has already burned more than 200 square miles. Some 400 structures have been reduced to rubble and the fire is threatening thousands more. One flank now stretches into the steep terrain of the Los Padres National Forest, Evans reports.

The string of wildfires chased more than 200,000 people from their homes. In the San Diego area, some evacuated to a local high school.

11:55 p.m.: Artist's prized painting saved while Bel Air mansion burns to the ground

After a Bel Air mansion burned to the ground, one artist was touched that firefighters were able to save his prized painting, CBS Los Angeles reports.

A photo of the painting against the backdrop of the home that was destroyed has gone viral.

CBS Los Angeles Brittney Hopper spoke to the world-renowned painter, Daniel Maltzman, Saturday.

The photograph really tells a story. A profound story. And in the photograph is his painting and it has the artist of the painting in tears.

Maltzman — who's based in Los Angeles — was watching the fire coverage closely when he saw the photograph. Thick black smoke in the background, a home burned to the ground, a firefighter pulling a hose and his painting unharmed.

"It's not about the picture. It's not about my painting. It's about the firefighters and it's about the gentleman that actually took that shot of the painting and it was so surreal that when I got it I was completely in shock."
