The case out of Dedham, Massachusetts, has turned into a yearslong whodunnit legal saga that has captivated true-crime fans across the country.

Karen Read pleaded not guilty to murder charges in the death of Boston police officer John O’Keefe and is facing a retrial after a jury was unable to reach a verdict last year.

The protesters fighting the court’s buffer zone in the high-profile Karen Read case have scored a win in federal appeals court. The buffer zone around Norfolk Superior Court in Dedham was expanded for the Read retrial after jurors during the first trial reported that they could hear loud protesters during deliberations.

Legal experts say the supervisor of the Massachusetts State Police trooper who was fired as lead investigator on the Karen Read case was "ill-prepared" and evasive in his testimony at the end of the trial's third week.
