Investigators say Roley intentionally set the fire to ambush the fire crew on Sunday and was perched in a sniper position, firing at the firefighters, according to the AP. They took cover behind firetrucks, but two died and a third was wounded during a barrage of gunfire over several hours, authorities said.

Two firefighters were killed and residents were ordered to shelter in place, but the order was lifted after police found a dead man in the woods.

Idaho authorities confirmed that a sniper who lured firefighters to a blaze they believe he set to ambush them had acted alone and had been found dead.
