Authorities said the fire appeared to have been intentionally set as part of an "ambush," and sheriff’s deputies took active sniper fire, Kootenai County Sheriff Robert Norris said.

A man whose body was found on Canfield Mountain next to a firearm is believed to have acted alone in opening fire at first responders, Sheriff Bob Norris said.

Authorities are no longer concerned about a possible second shooter, he said.
