Lindsay Clancy, a Massachusetts mother, is charged with three counts of murder and three counts of strangulation in the 2023 deaths of her three children, with the defense planning to argue severe postpartum psychosis made her legally not responsible.

The prosecution contends the killings were intentional and premeditated, while the defense cites postpartum psychosis and overdose risks; her nursing background is noted as a potential factor by defense attorney Donna Rotunno.

The defense argues severe postpartum mental illness impaired her ability to distinguish right from wrong.

CNN is covering the trial, with correspondent Joey Jackson providing details.

Patrick Clancy is expected to testify as the former husband, with coverage noting his remarriage and his role in the proceedings.

Mental health experts are anticipated to provide extensive testimony during the trial.

A jury of 12 women and six men has been seated in Plymouth Superior Court, allowing opening statements to proceed, with the trial focusing on mental state rather than explicit intent to kill.

Following jury selection, 18 jurors are seated; opening statements could lead to a multi-week trial, potentially lasting up to two months.

A judge restricted media access to audio of the 911 call and autopsy photos, allowing only non-broadcasted descriptions in court.

The court ruled that news organizations may not broadcast Patrick Clancy’s 911 audio or the children’s autopsy pictures.

Victims were Cora (5), Dawson (3), and Callan (7 months old); Callan died after hospital treatment for asphyxia-related complications.

Some reports indicate the specific strangulation charges were dropped prior to trial, leaving murder counts as the central charges.
