According to officials, 19 firefighters were killed fighting a wildfire in Yarnell, Ariz. The firefighters were trying to tame the Yarnell Hill Fire, which has now expanded to cover 2,000 acres. The fire began on Friday, but grew on Sunday in part to wind, high temperatures and low humidity. CNN reports that all of the firefighters who lost their lives were members of the Prescott Fire Department.
