Overview

  • The trial at Plymouth Superior Court is continuing with the defense presenting psychiatric evidence and Dr. Paul Zeizel testifying Thursday that Clancy had bipolar disorder with postpartum psychosis and was too sick to know her actions were wrong.
  • Prosecutors have presented a multiweek case using crime‑scene details, phone and wearable data and witness testimony to argue the killings were planned and that Clancy acted intentionally when she sent her husband out that night.
  • Judge William Sullivan has barred TikTok user and former McLean social worker Emily Thorndike from testifying while allowing Clancy’s McLean hospital records into evidence to show the care available to her.
  • Hundreds of supporters, many wearing pink, gathered outside the courthouse on Thursday to show solidarity and press for better attention to perinatal mental health, a rare condition estimated to affect about 1 to 2 in 1,000 births.
  • The jury must apply the legal standard for criminal responsibility, which differs from clinical diagnosis, to choose between a murder conviction that carries life without parole and a not‑criminally‑responsible verdict that would lead to involuntary psychiatric commitment; reporting has also highlighted questions about rapid medication changes and telehealth prescribing in Clancy’s care.
