Lindsay Clancy, a 36-year-old nurse, is charged with three counts of murder for the strangulation of her children Cora, Dawson, and Callan on January 24, 2023, in Duxbury, Massachusetts. ^[1] On September 1, 2026, the jury in the trial of Lindsay Clancy, accused of killing her three children in 2023, informed Judge William Sullivan that they failed to reach a unanimous verdict after more than 17 hours of deliberation. ^[2] The jury in the Lindsay Clancy murder trial in Plymouth, Massachusetts announced on Tuesday that they were deadlocked after four days of deliberation. ^[3] Lindsay Clancy, a 36-year-old former labor and delivery nurse, does not deny strangling her children in the basement of their home in 2023. ^[4] The jury in the Lindsay Clancy trial was expected to keep deliberating on Thursday to avoid a mistrial, despite being unable to agree on her criminal responsibility for killing her three children. ^[5] Clancy pleaded not guilty by reason of insanity, claiming she suffered from postpartum psychosis that prevented her from understanding the nature and gravity of her actions. ^[6] Prosecutors argued that Clancy knew what she was doing and made a conscious decision to kill her children before attempting suicide, noting her training as a nurse and her knowledge of the medications she was taking. ^[7] Judge William Sullivan asked the jury to deliberate once more, marking his second request for deliberation in the case. ^[8] Massachusetts law states that a judge can declare a mistrial only if the jury remains deadlocked after being asked to deliberate three times. ^[9] The jury is currently deadlocked over whether Lindsay Clancy is criminally responsible for killing her three children. ^[10] Defense attorney Kevin Reddington has argued that Clancy was experiencing postpartum psychosis when she killed the children and asked jurors to find her not guilty by reason of insanity. ^[11] If Clancy is convicted of first-degree murder, she faces life in prison without parole; if found not guilty by reason of insanity, she would be committed to a state psychiatric hospital for evaluation. ^[12]
