A community is in mourning and an investigation is underway following the deaths of 19 specially-trained Arizona firefighters.  Eighteen of the dead were members of the Granite Mountain Hotshots team.  They lost their lives yesterday battling the Yarnell Hill fire northwest of Phoenix.  Some were found inside individual fire shelters that were deployed as a last resort.

The wind-whipped blaze has charred a couple thousand acres since it started Friday and destroyed around 250 homes.
