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.

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.”

Firefighters were ambushed by a gunman while responding to a brush fire in Coeur d'Alene, Idaho, on Sunday, according to the local sheriff's office.
