Report: California wildfire sparked when tree hit power line

Officials say a Northern California wildfire that killed four people and destroyed more than 200 buildings last year was sparked when tree branches came into contact with Pacific Gas & Electric power lines.

LOS ANGELES - Officials say a Northern California wildfire that killed four people and destroyed more than 200 buildings last year was sparked when tree branches came into contact with Pacific Gas & Electric power lines.

Investigators with the California Department of Forestry and Fire Protection seized equipment belonging to PG&E after the Zogg Fire tore through rural communities in Shasta and Tehama counties.

Cal Fire said Monday that the investigation has determined that the blaze was caused by a pine tree contacting electrical distribution lines owned and operated by the utility.

PG&E officials on Monday said they were not given access to Cal Fire's report or evidence, but that they fully cooperated with their investigation.
