Investigators say arson is suspected in a blaze that destroyed 14 big-rig tractors and several trailers at California’s Harris Farms cattle operation, the state’s largest cattle feeder, beef processor and beef marketer. Fresno County sheriff’s investigators say the trucks in a storage yard were burning when firefighters and deputies arrived at the Coalinga property early Sunday at Interstate 5 and State Route 145. The Fresno Bee reported the fire was extinguished in 45 minutes.
