The Fire Marshall interviewed 2 people who saw the fire on the Hershberger side of the fence before it jumped to the homes, sounds clear to me somehow someone accidentally caused a fire by possibly tossing a cigarette into dry grass when they left for lunch and it then started the pile of plastic tiling which would create a very high temperature fire, it then also destroyed a truck, all on the other side of the fence but right up to if not on the face which the wind was blowing strong towards the Mobile Homes, it also caused heat and smoke damage to 2 other homes, the story should be titled 5 homes damaged 3 of them destroyed extensive damage to the other two
