Remembering 19 firefighters killed in Arizona (Photos)

<div class="meta image-caption"><div class="origin-logo origin-image kabc"><span>KABC</span></div><span class="caption-text">Robert Caldwell, 23, from Costa Mesa, Calif., is shown in this undated file photo. Caldwell was one of 19 firefighters who were killed battling a wildfire near Yarnell, Ariz.  Friends characterized Caldwell as the smart man in the bunch. 	 &#39;He was really smart. He had a good sense of humor,&#39; said Chase Madrid, who worked as a Hotshot for two years, but sat this year out. 	 &#39;He was one of the smart guys in the crew who could get the weather, figure out the mathematics. It was just natural for him,&#39; Madrid said. 	 It was Caldwell&#39;s intelligence and know-how that got him appointed as a squad boss. 	 His cousin, Grant McKee, also was one of the Hotshots killed Sunday. 	 &#39;Robert was a gentle giant - he was man of few words,&#39; said his aunt, Laurie McKee. 	 He had just gotten married in November, and had a 5-year-old stepson. 	 &#39;Both of these boys were only interested in having a family life. Robert was newly married, and Grant was engaged. They just wanted the house and the dog,&#39; McKee said. 	 Mary Hoffmann was grandmother to both boys. 	 &#39;To have two grandsons gone, it&#39;s devastation,&#39; she said.</span></div>
