COEUR D’ALENE, Idaho (AP) — A 20-year-old man’s life appeared to have begun to unravel in the months before authorities say he fatally shot two firefighters and severely wounded a third as they responded to a wildfire near Coeur d’Alene, Idaho.

Two firefighters were shot dead and a third wounded on an Idaho mountain when they were ambushed by a man who set the fire to lure them to the area, the local sheriff says.
