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.

In the wake of the deadly ambush on responding firefighters in Coeur d'Alene, Idaho, the suspect's grandfather spoke to ABC News on Monday.

Wess Roley, 20, was living out of his vehicle and his former roommate said he shaved off his long hair and started to "kind of go downhill.”
