Lindsay Clancy says she killed her children during a command hallucination

Boston, Massachusetts – Mrs. Lindsay Clancy, 36, who has been charged with murdering her three children, claims a postpartum psychosis‑related command hallucination compelled her to kill them. A forensic psychiatrist from the defense presented evidence on Friday that Clancy “lacked control” and could not distinguish right from wrong on the day the brutal killings occurred.

Clancy’s lawyer recounts that she was experiencing a delusion of influence, believing that strangling the children and leading them into heaven was a “favour” she was providing. The psychiatrist noted that on the day in question, the mother was “just following a command” rather than acting out a deliberate choice.

Despite the defense’s word, the prosecution offers a stark contrast, describing how the woman strangled her five‑year‑old daughter Cora, her three‑year‑old son Dawson, and her eight‑month‑old son Callan with fitness bands before leaping from a second‑floor window. The act, they argue, was a premeditated, intentional murder.

Clancy’s case has attracted widespread media attention, including a BBC Investigates feature titled “What is postpartum psychosis and why is it central in the Lindsay Clancy trial?”. In that piece, experts explain the rarity and severity of postpartum psychosis, noting it is a serious medical emergency distinct from the “baby blues.” A video interview with BBC Studios further contextualises the condition and its tragic potential, available at BBC.com.

The defense has also highlighted testimonies from Clancy’s mother and former mother‑in‑law, who describe a sharp decline in the woman’s mental health after the birth of her youngest child. They state that she had been seeking psychiatric treatment and even checked herself into a facility just days before the killings.

The court will set the final hearing in the coming week. The judge has cautioned the jury that if Clancy indeed suffered from a command hallucination and acted under an irresistible delusional state, she may not have met the criminal intent required for a murder conviction.
