Testimony from the prosecution's final rebuttal witness concluded on Wednesday in the murder trial of Lindsay Clancy. The 36-year-old mother is charged with first-degree murder in the 2023 strangulation deaths of her three children in Duxbury, Massachusetts.
The trial, which began on July 27, follows the January 24, 2023, deaths of 5-year-old Cora, 3-year-old Dawson, and 8-month-old Callan Clancy. While Clancy admits to the killings, she has pleaded not guilty, with her defense attorney arguing she was suffering from postpartum psychosis and was overmedicated. Prosecutors contend that Clancy was not psychotic and planned the acts.
Dr. Gregory Saathoff, a forensic psychiatrist and professor of emergency medicine, testified as the final witness for the prosecution. Saathoff, who interviewed Clancy in May and June of this year, stated there were inconsistencies in her account of a voice that allegedly ordered her to kill the children. He noted the voice did not provide instructions on how or where to carry out the acts, which he testified indicated Clancy "had control." He also characterized her subsequent suicide attempt as "very serious" despite the shallowness of her self-inflicted wounds.
Under Massachusetts law, a conviction for first-degree murder carries a mandatory sentence of life in prison without the possibility of parole. Conversely, if the jury finds that Clancy was not criminally responsible due to mental illness, she would be sent to a state psychiatric hospital. The outcome will depend on the jury's assessment of whether the defendant was experiencing postpartum psychosis—a severe mental health condition—at the time of the January 2023 events.
A verdict is expected to follow closing arguments, which are scheduled for Thursday. Once the jury receives instructions from the judge, they will begin deliberations to reach a unanimous decision. A person in this position would experience a transition from a local jail or medical facility to either a Department of Correction facility or a Department of Mental Health hospital depending on the jury's finding. Legal proceedings are expected to continue in Plymouth Superior Court through the end of the week.
