In the early morning hours of June 6, 1996 a frantic young mother of three from suburban Rowlett, TX makes a frantic call to 911 to report an intruder entered her home and viciously stabbed two of her sons to death. But when police arrive, they begin to notice disparities between the story Darlie Routier tells and the narrative the evidence creates. In the end, she receives the death penalty for her crimes. But one question persists. Was there really an intruder in the house that night?
