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.

One of the two firefighters fatally shot in an ambush in Idaho on Sunday was from Wisconsin. A lone gunman opened fire on crews responding to a brush fire on Canfield Mountain Sunday, near Coeur d'Alene, Idaho. Kootenai County Fire and Rescue Battalion Chief Frank Harwood was born in Neenah, Wis.
