Sonoma County vacant home fire was arson

The Sonoma County Sheriff's Department is investigating an arson fire that burned an 8,000-square-foot home May 11 south of Sebastopol.

Gold Ridge Fire District Battalion Chief Andy Pforsich said investigators found evidence that flammable liquid had been poured at several locations of the home on Gravenstein Highway South.

There was no power to the vacant, for sale home and the blaze was deemed suspicious, Pforsich said.

The roof and second story were destroyed and damage was estimated at $300,000.
