A gunman suspected of having started a fire to "ambush" firefighters in Idaho and kill them has been named as Wess Val Roley.
The 20-year-old is said to have aspired to become a firefighter before the attack on Sunday, which saw him allegedly perched in a sniper position, firing at the firefighters as they sought to put out a fire, which authorities believe he intentionally started.
Two firefighters were killed and one was injured as they came under gunfire over several hours, according to authorities.
They said the incident took place after they asked him to move his vehicle.
Roley was later found dead in the mountains with a firearm nearby.

Sky News' US partner networkNBC quoted Roley's grandfather,Dale Roley, as saying "something must have snapped" in his grandson for him to commit such violence.
"He actually really respected law enforcement," Mr Roley said. "He loved firefighters. It didn't make sense that he was shooting firefighters. Maybe he got rejected or something."

Mr Roley added: "I know he had been in contact to get a job with a fire department.
"He wanted to be part of a team that he sort of idolised."
Bob Norris, the sheriff of Kootenai County, said on Sunday: "We do believe that the suspect started the fire.
"This was a total ambush. These firefighters did not have a chance."
Officers said they were "taking sniper fire" near the city of Coeur d'Alene on Sunday afternoon, with crews responding to a fire at Canfield Mountain.
Mr Norris said the gunman had used high-powered sporting rifles to fire rapidly at first responders. The ambush continued for several hours.
More than 300 officers from city, county, state and federal levels responded. Two helicopters were deployed with snipers onboard.

First responders could be heard making urgent calls for help on their radios. "Everybody's shot up here… send law enforcement now," one dispatch said.
Later, the sheriff's office said members of a SWAT team "located a deceased male on Canfield Mountain", adding that a "firearm was found nearby".
