On Sunday, June 30, 2013, 19 members of the Prescott, Ariz.-based crew were killed in the deadliest wildfire involving firefighters in the U.S. for at least 30 years. The firefighters were forced to deploy their emergency fire shelters - tent-like structures meant to shield firefighters from flames and heat - when they were caught near the central Arizona town of Yarnell, according to a state forestry spokesman. &#40;AP Photo&#47;Cronkite News, Connor Radnovich&#41; <span class=meta>(AP Photo&#47; Connor Radnovich)</span>
