Mark and Donnah Winger seemed to have it all - successful careers, a new adopted child, and a nice home in Springfield, Ill. But their seemingly peaceful and happy family life was shattered in August 1995 when Mark says he came upon a man beating his wife with a hammer. Mark shot the man, and investigators soon determined that he had acted in self-defense. Update to a 48 Hours story originally aired on January 15, 2003. As correspondent Richard Schlesinger reports, while the case seemed open and shut, after several years, it turned out to be anything but.
