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.

Wess Roley once lived in Phoenix, with some of his family still living in the area, according to court records and social media posts.

The man who shot dead two firefighters and wounded a third after setting a blaze near a popular mountainside trail in Idaho was described by authorities on Monday as a young transient whose motives remained a mystery a day after the attack.
