Overview
- The prosecution rested on Monday, Aug. 17, 2026, after about three weeks of testimony and roughly 70 witnesses, clearing the way for the defense to call family members and clinical experts.
- Prosecutors presented forensic, medical and digital evidence they say shows planning and deliberate strangulation of the three children and a staged suicide attempt by Clancy.
- Defense lawyers plan to argue that Clancy suffered severe postpartum psychosis and bipolar disorder worsened by rapid medication changes and care from multiple providers.
- Jurors have heard phone searches, diary‑style notes and testimony from psychiatrists and first responders that paint sharply different pictures of her mental state and capacity at the time.
- The jury’s finding on criminal responsibility will determine whether Clancy faces life without parole if convicted of first‑degree murder or civil commitment to a Massachusetts psychiatric hospital.
