The judge in the Karen Read murder trial that ended in a mistrial has impounded the list of jurors for at least ten days. 

Judge Beverly Cannone says jurors in the case involving the death of Boston cop John O'Keefe in Canton could be exposed to harm if the list is released to the public. 

The order came as the defense filed their own motion alleging that the jury had reached not guilty verdicts for second degree murder and leaving the scene of a deadly crash.  The defense claims the only charge where the jury deadlocked was on OUI manslaughter.
