As a wildfire began to sow panic in a small northern Idaho mountain community, a group of firefighters who rushed to put out the blaze instead found themselves in an unexpected shootout.

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

Smoke continued to fill the air at Canfield Mountain after a shooter killed firefighters responding to a wildfire in Coeur D’Alene, Idaho. The town held a procession in honor of the two crew members who died.
