On January 24, 2023, three-year-old Dawson William Clancy was strangled to death by his mother, Lindsay Clancy, 32, inside the family's home at 47 Summer Street in Duxbury, Massachusetts. The mother, who had been suffering from postpartum depression and had been prescribed 13 psychiatric medications in a four-month period, allegedly used an exercise resistance band to strangle each of her three children — Dawson (3), his sister Cora (5), and infant brother Callan (7 months) — after sending her husband Patrick on an errand. She then attempted suicide by jumping from a second-story window. Patrick Clancy called 911 upon returning home. Dawson and Cora were pronounced dead at Beth Israel Deaconess Medical Center in Plymouth, while Callan was airlifted to Boston Children's Hospital in critical condition but later died. Lindsay Clancy survived but was paralyzed from the waist down. She was charged with two counts of murder, three counts of strangulation, and three counts of assault and battery with a deadly weapon, and was later indicted by a grand jury.

But suicidal thoughts kept surfacing, culminating in a break on Jan. 24."

Notable Details
Several notable details emerge from the text. First, the mother's defense attorney argued she was "prescribed 13 psychiatric medications in a four-month period" for postpartum depression (NYTimes, Document 2), raising potential systemic concerns about psychiatric medication management. Second, the mother was a labor and delivery nurse at Massachusetts General Hospital (Documents 3, 4), meaning she was a healthcare professional working with mothers and babies. Third, the prosecutor described the killings as "meticulously planned" — she "concocted an errand that would keep her husband, Patrick, out of the house for about 25 minutes" (Document 2). Fourth, while the fatality report and initial news coverage identify only Cora (5) and Dawson (3) as deceased, the NBC Montana article (Document 5) reports that the youngest child, Callan (7 months), also later died at Boston Children's Hospital — meaning all three children ultimately perished. Finally, the mother survived her suicide attempt but was left "paralyzed from the waist down" (Document 5), and her arraignment was conducted virtually via Zoom while she lay in a hospital bed (Document 2).
