Lindsay Clancy suffered 'command hallucination,' court hears
Forensic psychiatrist Phillip Resnick told jurors on Friday in the Lindsay Clancy trial that the Massachusetts mother was suffering a "command hallucination" when she killed her three children in January 2023, and could not control her conduct due to postpartum psychosis. The defence rested Friday; prosecutors say Clancy acted intentionally.
The widely watched case has put rare postpartum psychosis in the national spotlight, with closing arguments expected as the trial nears its end after nearly a month of testimony.
Key Takeaways
- Defence witness Phillip Resnick said Clancy experienced a command hallucination and a delusion of influence on the day of the killings.
- Prosecutors allege Clancy, now 36, intentionally strangled Cora, five, Dawson, three, and eight-month-old Callan before jumping from a second-floor window.
- Clancy's mother and former mother-in-law testified her mental health deteriorated after her youngest son's birth; she had checked into a psychiatric hospital days earlier.
- The case is expected to reach the jury early next week.
- Social media algorithms have amplified conspiracy theories and viral trial commentary, experts told The Guardian.
What did the forensic psychiatrist tell the jury?
Phillip Resnick, the defence's final witness, evaluated Clancy after the killings and reviewed her medical records. He testified Friday that "due to her mental disease," she was "unable to conform her conduct to the requirements of the law" when she took her children's lives.
"It was a matter where she was just following the command rather than being able to make any decision to do it or not," Resnick told jurors, according to the BBC.
Resnick said Clancy experienced not only a command hallucination but also a delusion of influence. In her mind, he testified, she believed she would be doing her children a favour by having them go to heaven with her rather than remain on earth without her mothering.
The defence does not dispute that Clancy carried out the killings. She has pleaded not guilty to three counts of first-degree murder, arguing postpartum psychosis left her unable to distinguish right from wrong.
What do prosecutors allege happened?
Prosecutors contend Clancy made a calculated decision to intentionally kill her children. They say that in January 2023 she strangled the three siblings with fitness bands in their Massachusetts home, then jumped from a second-floor window.
Clancy was paralysed by the fall and has attended the trial in a wheelchair. The defence says she experienced hallucinations and delusions after giving birth to Callan and was undergoing psychiatric treatment when the deaths occurred.
Earlier in the week, Clancy's mother and former mother-in-law, Susan Clancy, testified about her deteriorating mental health. "She was begging for help," Susan Clancy said of a woman she described as a very nurturing, very loving mother.
How has social media shaped the Lindsay Clancy trial?
As testimony wound down, an international social media discussion about the case reached a fever pitch. Amateur sleuths and armchair psychologists have posted content questioning evidence, including Clancy's last recorded heart rate and body temperature, and suggesting her ex-husband Patrick Clancy committed the crime — despite no legal evidence supporting that claim.
Experts say platforms like TikTok optimize for engagement, pushing trial content to users who might not otherwise follow the story. "Something like a conspiracy video is going to get a lot more legs than it would have in a different media environment," Boston University assistant professor Kathryn Coduto told The Guardian.
The frenzy has reached the courtroom. Defence attorney Kevin Reddington sought to add TikTok creator Emily Thorndike, a former McLean Hospital employee, to the witness list after she posted about Clancy's psychiatric stay. A judge found her credible but barred the testimony, citing limited materiality.
High-profile trials from Lizzie Borden to Johnny Depp v Amber Heard have long fueled public obsession. The Clancy case adds maternal mental healthcare to that conversation — a thread explored across our True Crime & Unsolved Mysteries coverage.
The UK's NHS defines postpartum psychosis as a rare, serious illness that can affect someone soon after childbirth — distinct from the "baby blues" and requiring emergency medical treatment.
