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.”

A northwest Idaho community is still reeling after a 20-year-old man was suspected of fatally shooting two firefighters and injuring another after intentionally starting a fire to ambush them.
