Ex-Husband Says Lindsay Clancy Appeared 'Happy' Before Children Were Killed — Case Sparks Postpartum Mental Health Debate

Patrick Clancy testified in a Massachusetts courtroom that his ex-wife, Lindsay Clancy, appeared to be in good spirits the morning their three children were killed in January 2023. Lindsay, 35, is charged with three counts of murder in the deaths of Cora, 5; Dawson, 3; and Callan, 8 months. She has pleaded not guilty.

On July 27, Patrick detailed months of worsening symptoms he said began about four months after Callan's birth, then described how Lindsay seemed to be having "one of her best days" the morning of the killings. Prosecutors say the murders were planned; the defense is pursuing an insanity defense, contending Lindsay was suffering from severe postpartum mental illness, including psychosis.

Timeline and Medical History

According to testimony, Lindsay first sought treatment for anxiety in September 2022 and was prescribed an antidepressant. When symptoms persisted, her prescriber advised increasing the dose. Friends and family later reported that her condition deteriorated despite medication changes. Patrick testified that Lindsay was hospitalized for suicidal thoughts and placed in a psychiatric facility after telling him she had "intrusive thoughts" about harming the children or that something bad might happen to them.

The Day Of The Tragedy

On the day of the deaths, Patrick said he worked from his basement while Lindsay spent time outside with the children building a snowman. That evening she texted him to ask about takeout; he sent his order and she called it in. To Patrick, everything appeared normal before the tragedy.

Lindsay Clancy cries in court on Monday, July 27, 2026 as she sees images of herself with her children playing at a indoor waterpark a month before they were killed.

"She seemed happy," Patrick said in court. "She was having one of her best days."

Experts On Perinatal Mental Illness

Mental health experts and advocates say the Clancy case highlights how rapidly symptoms can shift in severe perinatal illnesses. Latisha O'Connor, a licensed clinical social worker and certified perinatal mental health provider, told reporters that psychotic episodes often "wax and wane," and someone may appear manageable one moment and acutely unsafe the next.

Postpartum psychosis is rarer and more severe than the commonly known "baby blues" or postpartum depression, affecting roughly 1 to 2 in 1,000 new mothers. Symptoms can include delusions, hallucinations, extreme depression or a flattened affect, diminished need for or inability to sleep, paranoia or extreme suspiciousness, and rapid mood swings. Jessica MacNair, a licensed counselor who specializes in perinatal mood disorders, emphasized that postpartum psychosis is a psychiatric emergency that generally requires immediate, often inpatient, care.

Postpartum Support International estimates that about 4% of people with postpartum psychosis commit infanticide and roughly 5% die by suicide—statistics experts cite to underline the seriousness of untreated severe perinatal illness.

Broader Conversation And Barriers To Care

The case has prompted a national conversation about stigma, gaps in maternal mental health care, and how support systems often prioritize infant health over parental mental well-being. Many parents who shared their own experiences on social media said stigma and fear prevented them from seeking help sooner.

If you or someone you know is experiencing intrusive thoughts, severe mood changes, hallucinations, or suicidal ideation after childbirth, seek immediate professional help. Organizations such as Postpartum Support International can help connect families with providers trained in perinatal mental health.
