Jurors in the Karen Read trial asked four questions Tuesday, one indicating they may be facing the possibility of a hung jury, but left for the day without reaching a verdict.

Jurors in the murder retrial of Karen Read asked four questions related to the charges and evidence before ending deliberations on Tuesday.

The same issue arose at Read’s first trial: multiple jurors, in the wake of Cannone declaring a mistrial, reported to Read’s defense that they agreed to acquit her on two of the three counts, but they didn’t know they could return a partial verdict. That led to a lengthy appeals fight that was appealed to but not taken up by the U.S. Supreme Court.
