In June 1996 two boys were murdered in their home as they camped out in their living room. Their mother, Darlie Routier, was wounded and told police that an intruder had broken in and killed her sons. Shortly after the brutal murders, Darlie was arrested and found guilty of their killing - but is she guilty? Or has a huge mistake been made? We look at the evidence, both for and against her guilt, to try and see what really happened that night in the Routier home.
