The Lindsay Clancy murder trial ended in a mistrial after a jury deadlocked following nearly seven days of deliberation. Defense attorneys requested the removal of a holdout juror, but the court denied the motion, leading Judge William Sullivan to declare the jury deadlocked. Former federal judge Nancy Gertner analyzes the legal constraints that limited the judge's ability to intervene in the deliberation process. The Plymouth County District Attorney has not yet decided whether to seek a retrial, while Clancy remains held in a state hospital.
