The man who police believe killed two Idaho firefighters responding to a brush fire after starting the flames himself had wanted to pursue a career in the fire service, his grandfather told CNN.

Jason Roley, the father of accused shooter Wess Roley, said his son had gotten a GED and moved to Idaho, intending to be in the military.

The sniper who shot dead two firefighters in an ambush in Idaho was identified Monday as 20-year-old Wess Roley — and an eerie photo shows him delivering a sinister glare into the camera.
