Overview
- Prosecutors and defense finished more than three weeks of testimony with roughly 84 witnesses over 21 days, and the court set closing arguments for Thursday, Aug. 27.
- Two prosecution experts, forensic psychologist Kirk Heilbrun and FBI psychiatrist Gregory Saathoff, told jurors they believe Clancy retained the capacity to know right from wrong and questioned her claim of a single command hallucination.
- The defense presented testimony that Clancy suffered severe postpartum psychosis and that rapid changes in psychiatric medications and telehealth care contributed to her collapse into psychosis.
- Jurors will be instructed on Massachusetts’s two‑pronged legal test for lack of criminal responsibility and may return verdicts ranging from first‑degree murder, which carries mandatory life prison, to not guilty by reason of lack of criminal responsibility, which would likely lead to involuntary psychiatric commitment.
- The trial has focused on phone forensics, medical records, sealed 911 audio and impounded autopsy images and has intensified public debate about perinatal mental health care, telemedicine prescribing and oversight of treatment.
