 He killed a teenager in front of his mother, jamming his gun into the boy's mouth. Abdul Wahab said he saw the boy's mangled head. He killed one man as Iraqi medics were treating him. He killed another while he lay in bed beside his wife. I asked what had happened to Will. Abdul Wahab said he didn't know. Will was transferred one day, and that was the last he'd seen of him, but he reckoned that a man like him must have met his judgment eventually.
