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.”

Authorities identified the suspect as Wess Roley. Kootenai County Sheriff Bob Norris said it appeared he had been living in his car, and authorities did not know why he was in the area. Roley, who dreamed of becoming a firefighter himself, was found dead on the mountain from a suspected self-inflicted gunshot wound.

Wess Roley, who authorities say took his own life after Sunday’s shootings, is suspected of killing two battalion chiefs in Sunday's ambush.
