Who were the men of Granite Mountain Interagency Hotshot Crew killed fighting the Yarnell Hill fire Sunday?
Fourteen of the men were in their 20s. Three of them have babies on the way.
Meanwhile, the fire they were fighting is still burning out of control.
Arizona's governor has signed an emergency declaration, which frees up money to help fight the fire.
She called the deaths "unbearable."
USA Today reports the United Way of Yavapai County, Arizona, has set up a fund to benefit the families of the men who died, along with people who've lost homes in the Yarnell Hill fire. CLICK HERE to go to the website if you would like to make a contribution.
