From The Update

"MASSIVE FIRE — About 300 acres north of County Road 3657 near Salt Creek were destroyed by fire yesterday afternoon . . . The cause of the fire isn’t clear, but a cigarette flicked from a moving car is thought to be the culprit." Huh? It's not "clear" presumably means there were no eyewitnesses that could definitively tells us what happened, but a "cigarette flicked" from a car is "thought" to be the reason? Where does that come from?
