Six residents of a house in Valencia were injured, three critically, when a serious fire destroyed the home. The blaze started around 6:25am, and some of the residents attempted to escape by jumping from second-story windows. Two adults and a child suffered serious injuries, and were transferred to the Grossman Burn Center in Sherman Oaks for treatment. Neighbors said they were celebrating with the family Monday night at their annual holiday party. Inspectors said they are uncertain whether the celebration or decorations at the residence are linked to the blaze.
