Two days after neighbors heard a loud blast and a fire suddenly sparked at the home of actor Alex O'Loughlin, investigators have determined the cause: spontaneous combustion.
Honolulu investigators say the fire Monday afternoon at the Hawaii Five-0 star's Diamond Head home began in a pile of oily rags in the garage that were used for a wood project.
Firefighters kept the flames mostly confined to the garage and its contents. Damages are estimated at $110,000.
O'Loughlin lives in the multi-million dollar home with former model Malia Jones and three children. No one was injured.
