In an interview with ABC News on Tuesday, a former classmate of Roley's said that while the alleged sniper was always "really different," he still has "a hard time trying to correlate the same Wess that I grew up with to the Wess that did what he did."

The suspect, who died on Sunday and was found with a firearm nearby, was a 20-year-old man, according to a law-enforcement official.

Two firefighters were shot dead and a third wounded on an Idaho mountain when they were ambushed by a man who set the fire to lure them to the area, the local sheriff says.
