Lindsay Clancy, a 35-year-old mother from Duxbury, Massachusetts, stood trial on July 27, 2026, accused of murdering her three children in January 2023.
She has pleaded not guilty, claiming severe postpartum psychosis rendered her not criminally responsible.
Clancy faces three counts of murder for the deaths of Cora, 5; Dawson, 3; and 8-month-old Callan.
Prosecutors say she strangled them with exercise resistance bands in their home.
After the killings, Clancy attempted suicide by jumping from a second-story window, resulting in paralysis from the waist down.
Prosecution vs. Defense
The prosecution argues Clancy acted with deliberate premeditation and extreme cruelty, asserting she was fully responsible.
The defense, led by attorney Kevin Reddington, contends her mental illness negates criminal culpability.
Clancy had sought treatment for postpartum mental health issues before the incident, including a voluntary psychiatric hospitalization weeks earlier.
Her ex-husband, Patrick Clancy, who discovered the children and made a 911 call, is expected to testify first.
He supports the defense's view, stating in 2024, "I wasn't married to a monster — I was married to someone who got sick."
Patrick's testimony will cover Lindsay's mental health struggles and the events of that day. The defense will cross-examine him to probe these issues further.
The trial will feature dueling psychiatric experts.
The prosecution's witnesses include Dr. Kirk Heilbrun, Dr. Avram Mack, Dr. Gregory Saathoff, and Dr. Margarita Abi Zeid Daou.
The defense will present Dr. Phillip Resnick, Dr. Margaret Spinelli, and Dr. Paul Zeizel, all specialists in postpartum psychiatric disorders.
The case draws parallels to Andrea Yates' 2001 trial, where an insanity defense succeeded after she drowned her five children.
Experts note postpartum psychosis is rare but can cause hallucinations and delusions leading to harm.
Lawsuits filed by Lindsay and Patrick Clancy accuse her healthcare providers of misdiagnosis and overmedication, intensifying her condition.
The jury, composed of 12 women and six men, was screened for mental health biases.
The court has prohibited media from recording or distributing Patrick Clancy's 911 call and autopsy photos to protect family privacy.
If found guilty, Lindsay Clancy faces life imprisonment without parole.
If the insanity defense succeeds, she would be committed to a psychiatric facility for ongoing treatment and periodic review.
