Evidentiary re-evaluation
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.

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.

Plea & Disposition Window
