 A judge declared a mistrial Monday after jurors deadlocked in the polarizing and much-watched case of Karen Reed, a woman accused of striking her Boston police officer boyfriend with her SUV and then leaving him to die in a snowstorm. Prosecutors say they intend to retry the case in which the defense asserted that Reed had been framed by police after John O'Keefe was beat up at a fellow officer's house. Judge Canone, despite our rigorous efforts, we continue to find ourselves at an impasse. Our perspectives on the evidence are starkly divided.
