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 suspect who police believe gunned down two firefighters Sunday after starting a brush fire in Idaho wanted to pursue a career as a firefighter himself, his grandfather told CNN.

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.”
