The mistrial followed repeated reports from jurors that they could not reach a consensus. Clancy's attorney sought to have a juror removed after the foreperson reported that one juror had expressed doubt but was not applying it to the verdict; Judge William Sullivan declined to remove or further question the juror, and Massachusetts' highest court rejected an emergency appeal seeking additional inquiry. Prosecutors have not decided whether to retry the case, while a conviction could result in life imprisonment and an insanity finding could lead to continued confinement in a psychiatric facility. The case has also drawn broader attention to postpartum mental illness and the legal standards governing criminal responsibility in cases involving severe psychiatric disorders.
