8/24/2026, 11:05:58 AM
The Trial and Charges
The criminal case against Lindsay Clancy, a 36-year-old mother from Duxbury, Massachusetts, is being heard in the Plymouth Superior Court. She faces three counts of first-degree murder for the strangulation deaths of her children—5-year-old Cora, 3-year-old Dawson, and 8-month-old Callan—in January 2023. After the killings, Clancy attempted suicide, leaving her paralyzed from the waist down. The prosecution seeks a mandatory life sentence without parole; the defense asks the jury to find her not criminally responsible by reason of insanity.
Defense Strategy and Mental-Health Claims
Defense attorney Kevin Reddington is pursuing an insanity defense, arguing that Clancy was suffering from postpartum psychosis. He says her providers failed to diagnose and properly treat her bipolar disorder with postpartum onset, prescribing a regimen that may have worsened her condition.
Forensic psychiatrist Dr. Phillip Resnick testified that Clancy experienced “command hallucinations” in which a male voice told her to kill her children and herself, and diagnosed her with bipolar disorder with major depression, concluding she should not be held criminally responsible.
Forensic psychologist Dr. Paul Zeizel corroborated the auditory hallucinations and characterized her condition as postpartum psychosis, noting she had sought help for months, including a hospital admission three weeks before the deaths.
Chaplain Sheila Cavanaugh, who met Clancy after the incident, testified that Clancy “alluded to hearing a voice” and later expressed relief that “her children are safe.”
Prosecution Position
Prosecutors argue the killings were planned and that Clancy understood the wrongfulness of her actions. Child and forensic psychiatrist Dr. Avram Mack testified that Clancy displayed normal thinking, the ability to plan, and awareness of legal standards, asserting she should be found criminally responsible.
Public Reaction
The case has sparked a national conversation about maternal mental health and the balance between compassion and accountability.
- “It should not take tragedy for people to pay attention to mental health,” — Renee Kimball, organizer of the courthouse demonstration.
Data & Statistics
- Victims: Cora, Dawson, Callan (8 months).
- Date of killings: January 2023.
- Possible outcomes: life imprisonment without parole or commitment to a state psychiatric hospital with periodic review.
Conflicting Reports & Gaps
Experts disagree on the clinical definition of postpartum psychosis. Dr. Mack cited a guideline limiting the postpartum period to four weeks, while defense experts argue the condition can extend up to a year. Defense witnesses describe vivid hallucinations and loss of control; prosecution experts maintain Clancy functioned normally on the day of the killings, citing her ability to drive her daughter to a doctor hours earlier. The trial record lacks a definitive psychiatric diagnosis from the state’s own evaluators.
What’s Next
Closing arguments are slated for the coming week, after which jurors will begin deliberations. A not-guilty verdict by reason of insanity would result in commitment to a state psychiatric facility; a guilty verdict would bring a mandatory life sentence without parole.
