Jurors in Lindsay Clancy’s murder trial are set to begin deliberations Thursday after closing arguments and instructions from Plymouth Superior Judge William F. Sullivan. Sullivan told the panel Wednesday: “Rest up and be ready for tomorrow.”
That move sends the case into its final phase after 21 days of testimony from 84 witnesses. The 18-member panel will first lose six members at random as alternates, leaving 12 jurors to decide whether Clancy is guilty of three counts of first-degree murder or whether her mental condition changes the legal outcome.
Clancy has admitted she strangled 5-year-old Cora, 3-year-old Dawson and 8-month-old Callan with exercise bands in the basement of the family’s Duxbury home on Jan. 24, 2023. She has also pleaded not guilty and is asserting an insanity defense, saying she suffered a postpartum psychotic break and heard a man’s voice telling her to kill the children and herself.
After the slayings, she slashed her wrists and neck and jumped from a second-story window, leaving her paralyzed from the waist down and appearing in court each day in a wheelchair. That image has become part of the case’s force: the woman jurors must judge is also the woman who cannot stand beside the lawyers arguing over what she knew, believed and intended.
The split in the case is plain. Prosecutors say the killings were premeditated. Gregory Saathoff, testifying Wednesday as the prosecution’s final witness, said in his opinion Clancy suffered from Bipolar II disorder but still “did have the capacity to appreciate right from wrong” and should be held criminally responsible for killing her children. He also said she was “methodical and quite controlled,” pointing to her taking her daughter for a checkup, building a snowman with the children and texting photos to her husband and mother on the day of the slayings.
That leaves jurors with a narrow legal question after a vast record: whether Clancy’s illness overwhelmed her ability to appreciate what she was doing, or whether the state has proved deliberate murder beyond that defense. The answer should come only after final arguments, the judge’s instructions on murder, mental illness and criminal responsibility, and the sort of private deliberation that often begins with one juror testing the strength of the others’ doubts.
For readers following the Clancy trial live, Thursday is the day the evidence stops and the verdict process begins. The remaining question is not whether the jury will reach the case quickly, but whether the facts already heard will push 12 jurors to the same conclusion.
