He was a wonderful father,” Janet Walker said of her husband, David Jack Walker of Edmond. “He loved his three girls more than any father could. He never hung up the phone without saying, ‘I love you.'” The environmental specialist with Housing and Urban Development was “a funny man with a big heart,” his wife said. “He laughed all the time.” Walker, 54, was a lifetime member of the First Baptist Church of Nicoma Park and was actively serving on the building committee. In addition to his three daughters, he had a stepson and two grandsons.
