THE suspected gunman who lit a wildfire to lure firefighters into tackling a blaze before shooting them dead shared a sinister warning on social media – hours before the ambush. 

Wess Roley, 20, allegedly killed two firefighters and left a third fighting for their life after opening fire in Coeur D’Alene in Idaho on Sunday.

Roley was found dead around six hours after fire crews received the initial calls about the blaze in the mountain range.

Cops on Monday shared photos of Roley wearing camouflaged gear that he shared on social media. 

He shared lyrics from a Bjork song, warning: “I’m going hunting.”

Investigators are still probing what motivated Roley to carry out the shooting – which has left family members reeling.

Police revealed they didn’t find any manifesto.

Roley’s grandpa, Dale, said he had no idea his grandson could carry out the killings.

Dale told the New York Times that he was close with Roley, but the pair lost contact around a month ago.

He said that Roley had lost his cell phone. 

Dale revealed that his grandson had dreams of becoming a firefighter.

“He loved firefighters,” he told NBC News.

“It didn’t make sense that he was shooting firefighters.”

Dale speculated that Roley may have been rejected as he said he was actively pursuing that career path.

He suggested his grandson would’ve fitted in well in the fire service because of his tree climbing skills.

“He was just trying to figure his life out,” he told The New York Times.

“He seemed to be a little bit optimistic.”
