"The Devil You Know" -- Donnah and Mark Winger of Springfield, Illinois seemed to have it all. She was an OR nurse, he a nuclear safety tech. They were active members of their temple, good neighbors and, after struggling for years with infertility, had just adopted a baby girl. They finally had the life they dreamed of. But one day their dream was shattered. After receiving a 911 call from Mark, police officers arrived to find Donnah and another man sprawled on the kitchen floor. Mark had a terrifying story to tell about a strange cab driver who had recently scared Donnah and had returned to the house to attack her. When Mark shot the man in self defense, both Donnah and the stranger died. The grieving widower moved on with his life for four years, until a rookie detective re-opened the case and uncovered some unlikely evidence that unraveled Mark's story and pointed investigators to what really happened.
