"A gunman deliberately started a wildfire in a rugged mountain area of Idaho and then shot at the firefighters who responded, killing two and injuring another on Sunday afternoon, in what the local sheriff described as a 'total ambush.'"

"Law enforcement officers exchanged fire with the gunman while the wildfire burned. Officials later found the body of a male suspect on the mountain with a firearm nearby.... The authorities said they believed the suspect had acted alone, but they did not release any information about his identity or motives. 'This was a total ambush,' Sheriff Norris said. 'These firefighters did not have a chance.'... Graham Christensen, a past president of the Lake City Trail Alliance, said the Coeur d’Alene Fire Department regularly performed brush clearing and fire suppression there, and said he did not know of a naturally caused wildfire there in the past two decades. He said the attack was a shock because the area had always felt so safe. 'Everybody feels comfortable up there,' he said...."
