Karen Read is asking the U.S. Supreme Court to take up her double jeopardy appeal. 

Read's attorneys say jurors in Read's trial over the death of Boston cop John O'Keefe had voted to acquit her on second degree murder and leaving the scene of a crash at her trial.  The trial court judge, state Supreme Court and two federal courts have already rejected Read's appeal. 

The trial judge did not poll the jury on whether they had reached a verdict on any of the three charges before declaring a mistrial.
