She had pleaded not guilty to second-degree murder, manslaughter while operating a motor vehicle under the influence and leaving the scene of a fatal accident.
After jurors told the court earlier Monday they had been unable to attain a consensus, Judge Beverly Cannone read them the Tuey-Rodriguez instructions and had them return to their deliberations. Per Tuey-Rogriguez, the judge would be forced to declare a mistrial if the jury returned once more undecided.
In a note to the court Monday afternoon, the jury said it was unable to reach a unanimous consensus despite an exhaustive deliberation process.
"Despite our rigorous efforts we find ourselves at an impasse," the note, as read aloud by Cannone, said. "The deep division is not due to lack of consideration but to a severe adherence to our personal beliefs and moral compasses. To continue to deliberate would be futile."
In response, Cannone stated, "Your service is complete. I am declaring a mistrial."
A status conference has been scheduled for July 22 in the case.
The Norfolk District Attorney's Office said it plans to retry the case.
