New details are emerging about the 20-year-old suspect that police say started a brush fire and then began shooting at firefighters responding to it in an ambush-style attack. Police say he has no criminal record and likely used a shotgun before dying from a self-inflicted wound six hours after the shooting began.

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.”
