C OEUR d’ALENE, Idaho (KMVT/KSVT) — Firefighters fully contained a wildfire in Northern Idaho that the Kootenai County Sheriff’s Office believes was started intentionally to ambush firefighters.

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.

Authorities believe that the “total ambush” that killed two firefighters and injured a third in Coeur d’Alene, Idaho, was carried out by a lone gunman who intentionally set the fire to lure first responders.
