The 19 firefighters killed Sunday in Arizona were members of an elite crew known for battling the region’s worst fires, including two earlier this season before all but one member of the team died in the deadliest U.S. wildfire for firefighters in decades. Prescott Fire Chief Dan Fraijo said the 19 firefighters, whose names had not been released, were part of the city’s fire department. "We’re devastated," Fraijo said late Sunday. "We just lost 19 of the finest people you’ll ever meet."
