The murder trial of Lindsay Clancy, a former maternity nurse accused of killing her three young children in Duxbury, Massachusetts, has captivated audiences in the US and beyond, becoming known as "America's saddest murder trial". Clancy, 36, is accused of strangling her children – Cora, five, Dawson, three, and eight-month-old Callan – in the family's basement in a premeditated attack, before attempting to take her own life. The case has sparked intense debate online, particularly around her mental health following childbirth and questions over whether her husband, Microsoft executive Patrick Clancy, bears any responsibility.

Patrick Clancy discovered the scene after returning from a pharmacy and takeaway run, finding his wife critically injured in the garden and his children unconscious with exercise bands around their necks; Cora and Dawson were pronounced dead, while Callan died three days later after being declared brain dead. The trial, held at Plymouth Superior Court and televised daily, has heard that Lindsay had suffered for months with severe postpartum symptoms including insomnia, anxiety and suicidal thoughts, for which she and her husband repeatedly sought medical help, and she had been prescribed numerous psychiatric medications in the months before the killings.
