Four more car fires broke out in the Los Angeles area New Year’s Eve, leaving authorities to probe for any links to a series of arson blazes that burned dozens of cars and spread to some structures in recent days. In a sobering counterpoint to the typical revelry of the night, fire trucks were stationed in neighborhoods, police patrolled the city, switchboards took hotline calls and thousands in rewards were offered. Firefighters quickly put out a car fire at about 6 p.m. Saturday in Hollywood that "fits the profile of concern" authorities have been following for the arsons, fire department spokesman Brian Humphrey said.
