JOINT BASE LEWIS-MCCHORD, Wash. -- Mary Coghill Kirkland said she asked her son, 21-year-old Spc. Derrick Kirkland, what was wrong as soon as he came back from his first deployment to Iraq in 2008.
He had a ready answer: "Mom, I'm a murderer."
He told her how his team had kicked in the door of an Iraqi house and quickly shot a man inside. With the man now lying wounded on the floor, "my son got ordered by his sergeant to stand on his chest to make him bleed out faster," Kirkland said. "He said, 'We've got to move, and he's got to die before we move.' "
