What began as a routine response to a brush fire on northern Idaho’s Canfield Mountain turned deadly Sunday after firefighters reported someone shooting at them while they battled the flames.

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.

Officials have identified the two firefighters who were killed in an ambush shooting as they responded to a wildfire report near Coeur d'Alene, Idaho, on Sunday, June 29
