BOISE, Idaho (AP) — A man armed with a rifle started a wildfire and then began shooting at first responders in a northern Idaho mountain community, killing two firefighters and wounding a third during a barrage of gunfire over several hours, authorities said.

A shelter-in-place order was lifted Sunday night after a tactical response team used cellphone data to “hone in” on a wooded area where they found the suspect's body with a firearm nearby as flames rapidly approached, Kootenai County Sheriff Bob Norris said.

Investigators said he acted alone.

The suspect has been identified as Wess Roley, a law enforcement official told The Associated Press on Monday. The official spoke on the condition of anonymity because they were not authorized to discuss the investigation.

“We do believe that the suspect started the fire, and we do believe that it was an ambush and it was intentional,” Norris said at a Sunday night news conference. “These firefighters did not have a chance.”

Sheriff's officials said crews responded to a fire at Canfield Mountain just north of Coeur d’Alene around 1:30 p.m. Sunday, and gunshots were reported about a half hour later.

Three victims were brought to Kootenai Health, hospital spokesperson Kim Anderson said. Two were dead on arrival and the third was being treated for injuries, Anderson said. The wounded firefighter was “fighting for his life” after surgery and was in stable condition, Norris said.

The scene was sheer pandemonium as the brush fire burned and firefighters rushed to the scene only to come under heavy fire.

First responders made urgent calls for help on their radios: “Everybody’s shot up here ... send law enforcement now,” according to one dispatch.

Idaho Gov. Brad Little said “multiple” firefighting personnel were attacked.

“This is a heinous direct assault on our brave firefighters,” Little said on X. “I ask all Idahoans to pray for them and their families as we wait to learn more.”

Norris said it appeared the sniper was hiding in the rugged terrain and using a high-powered rifle. He said he instructed deputies to fire back.

An alert by the Kootenai County Emergency Management Office asked people to avoid the area around Canfield Mountain Trailhead and Nettleton Gulch Road, about 4 miles (6.5 kilometers) north of downtown Coeur d’Alene.

Though the shelter-in-place order was lifted, the sheriff’s office cautioned residents to be prepared because the fire was still burning. The status of the fire was not immediately known Monday morning.

The FBI responded to the scene with technical teams and tactical support, Deputy Director Dan Bongino said.

The Idaho House Republican Leadership said in a statement: “We are horrified by the murder of two firefighters in Coeur d’Alene, and shocked by such a vicious attack on our first responders. We are praying for them, the injured, their families and their colleagues.”

Coeur d'Alene is a city of 55,000 residents near the border with Washington. Canfield Mountain is a popular hiking and biking area on the city's outskirts, covered with trees and heavy brush and crisscrossed with trails that lead into a national forest.

Fire is always a big concern for the region, said Bruce Deming, whose property abuts the trail system. When he noticed smoke on the ridge Sunday afternoon, he wondered why no firefighting helicopters were responding.

When a friend texted to tell him about the shooting, he realized why he wasn’t seeing aircraft: “Because they’re concerned about being shot at,” he said.

As deputies set up posts nearby, Deming pointed them to a trail that starts near his backdoor and leads directly to the site of the fire.

“I just don’t want to have to wake up in the middle of the night to figure if somebody’s out prowling around my place,” he said.
