A man who had intentionally set the fire to ambush the crew on Sunday was perched in a sniper position, firing at the firefighters, according to the AP. They took cover behind firetrucks, but two died and a third was wounded during a barrage of gunfire over several hours, authorities said.

Wess Roley has been identified as the suspect behind the deadly shooting, according to a law enforcement official who spoke to the Associated Press on condition of anonymity.
