The trial for Lindsay Clancy, a Massachusetts mother accused of fatally strangling her three young children, commenced Monday in Plymouth. Clancy, 35, who is wheelchair-bound following a suicide attempt, appeared stoic in court during jury selection. The case is expected to hinge on whether jurors believe she was suffering from severe postpartum psychosis and was not aware of her actions.

Experts suggest the core of the trial will revolve around Clancy's mental state at the time of the alleged crimes on January 24, 2023. The defense plans to argue that Clancy was not in her right mind and was potentially hearing voices, leading her to commit the acts. Her legal team intends to present medical experts who will testify about postpartum psychosis, the treatment Clancy received, and the medications she was prescribed.

Prosecutors are expected to counter with their own medical experts, aiming to demonstrate that Clancy was lucid enough to plan the events, including ensuring her husband was out of the house. The charges against Clancy include murder and assault for the deaths of her children, Dawson, 3, Cora, 5, and 8-month-old Callan, whom she allegedly strangled with exercise bands.

Clancy, a former labor and delivery nurse, reportedly attempted suicide by cutting her wrists, throat, and jumping from a second-story window, resulting in paralysis from the waist down. Her defense may leverage her paralysis and the potential for jury sympathy.

Both Clancy and her husband, Patrick Clancy, have filed lawsuits against the physicians who treated her, alleging a failure to diagnose her postpartum psychosis and bipolar disorder. The lawsuits also claim that she was subjected to a cocktail of powerful psychiatric medications. Legal experts believe the defense strategy could raise sufficient doubt for a not guilty by reason of insanity verdict or a conviction on a lesser charge.

Advocates for perinatal mental health have stated that Clancy's described condition aligns with textbook postpartum psychosis and suggested that improved awareness and specialized treatment could have prevented the tragedy. They noted that women sometimes struggle to access adequate specialized care.

The trial is anticipated to last between one and two months, with as many as 200 witnesses, including Patrick Clancy, potentially testifying. Eighteen jurors, including alternates, will be selected for the proceedings.
