SOBOBA HOT SPRINGS, Calif. -- As fire crews battle a three-day-old wildfire in Southern California, the mother of one of four firefighters killed in the blaze is urging the person responsible to come forward.
Bonnie McKay, whose son Jason died Thursday, said: "Don't let the remorse eat you alive. Come forward. ... I for one will try not to judge you."
The reward for information leading to the arrest of the arsonist who started the wildfire is now a half million dollars.
Mild temperatures and calmer winds have helped more than 2,700 firefighters as they continue to attack the blaze. A fleet of aircraft, including a DC-10 jet, is being used to dump water and retardant onto flames.
Authorities say the fire, which has spread across 62 square miles, is 40 percent contained.
