PLYMOUTH, MA — Lindsay Clancy’s murder trial opened this week with dueling accounts of whether the former Massachusetts nurse knowingly killed her three young children in 2023 or whether a severe postpartum psychiatric crisis drove the killings. Clancy is charged in the deaths of Cora, 5, Dawson, 3, and Callan, 8 months, and the central issue for jurors is her mental state when the children were strangled inside the family’s Duxbury home.

Opening statements and testimony from former husband Patrick Clancy began Monday, with defense attorney Kevin Reddington arguing that postpartum psychosis, bipolar symptoms and overmedication shattered Clancy’s grasp on reality, while prosecutors argued she acted deliberately and understood what she was doing, according to WTNH, WCVB and The Associated Press.

Prosecutors told jurors Clancy used exercise bands to strangle the children one by one after sending Patrick Clancy out to pick up food and medicine, then tried to kill herself. She survived but was left paralyzed after jumping from a second-floor window, and she has pleaded not guilty while pursuing a lack-of-criminal-responsibility defense.

Patrick Clancy, the first witness called by the state, testified that his then-wife’s mental health spiraled in late 2022, with suicidal thoughts and fears that something might happen to the children. He also said she seemed unusually happy on the day of the killings and described it as one of her best days, a contrast that now sits at the heart of the battle over whether she was legally sane.

The trial is expected to last several weeks, with jurors set to hear more testimony about Clancy’s mental health treatment, medications and the timeline inside the home before the children’s deaths. Court was scheduled to resume Wednesday morning.

Presumption of Innocence: A presumption of innocence means that any defendant in a criminal trial is presumed to be innocent until they have been proven guilty beyond a reasonable doubt in a court of law. The defendant in this case is only accused of the charges set forth in the criminal complaint. They are innocent until proven guilty.
