Clay Bonnyman Evans knew all there was to know about his grandfather though the two had never met until that moment under several feet of crushed coral rock on a remote island in the Pacific. Evans was polite when requesting the anthropology brush he would use to sweep some of the dust from his grandfather’s remains when they were found in May on the Tawara Atoll. “My whole life I grew up with that medal on the wall and the citation,” Evans said, holding back tears. “He’s always been my hero.”
