Legal Precedent Assessment: Under Massachusetts law, when a jury deadlocks after extensive deliberation (6 weeks), the prosecution retains complete constitutional authority to retry without Double Jeopardy violation. However, the high psychiatric expert weight (78%) makes jury unanimity exceptionally difficult to achieve, creating strong structural incentive toward a mediated plea or commitment to a secure mental health institution.

Prosecution Procedural Decision Timeline Next 30–360 Days

Days 1–30
Status Conference & Juror Polling Debrief The court schedules a post-mistrial hearing. District Attorney reviews non-binding feedback from deadlocked jurors to assess count splits (e.g., 10-2 for manslaughter vs murder).
Days 30–90
Evidentiary Motions & Expert Deposition Review Defense petitions for renewed bail/custody terms at Tewksbury or specialized medical facility. Both sides re-evaluate medication records and postpartum clinical testimonies.
Days 90–180
Plea & Disposition Window Peak period for confidential negotiations. If prosecution resolve remains high (85%), negotiations may fail, forcing a second trial date assignment.
Months 8–14
Retrial Commencement (If Not Settled) New jury selection begins from an expanded venire due to intense national media publicity. Second trials historically exhibit higher settlement rates before opening statements.
