Watch: Parents of Oxford school shooter Ethan Crumbley in court for trial

More than two years after the Oxford High School massacre, a historic trial begins this week for Jennifer and James Crumbley, as prosecutors seek to do what has never been done before: hold parents criminally responsible for a deadly mass school shooting. After months of legal feuding and mudslinging by lawyers, it will finally be up to a jury to decide this unprecedented and significant issue. Legal experts stress that the first critical task at hand, jury selection, could ultimately decide the case.
