It\u2019s 7:09am, June 20 1994, Dunedin New Zealand. 22-Year-old David Bain calls emergency services 111. Clearly distressed he tells the operator \u2018They\u2019re all dead, they\u2019re all dead\u2019. Police and Ambulance arrive 20 minutes later to a grisly scene. David\u2019s mother, father, two sisters and brother are all shot dead. Four days later, David would be charged with their murder. David says it was his father and that he didn\u2019t do it. This case will split a nation. Did he do it, or didn\u2019t he? Murder or murder suicide. Did police screw up the investigation?
