DUXBURY, MASS. (WHDH) - Patrick Clancy, the husband of a Duxbury mother accused of strangling and killing her three children, is suing his wife’s medical team, accusing them of overmedicating her and not doing enough as her mental health declined.

The case is filed on behalf of his children’s estate.

The lawsuit claims doctors overprescribed medication to his wife, Lindsay Clancy, during her treatment for post-partum depression, and failed to monitor her deteriorating mental health.

Prosecutors said in January 2023, Clancy strangled her three young children with exercise bands inside their Duxbury home while her husband was out picking up dinner.

Investigators said she then jumped from a window in an attempted suicide. She is now paralyzed and confined to a wheelchair. She’s pleaded not guilty to the murders.

Patrick said in the months and days leading up to the tragedy, the doctor his wife was seeing from Aster Mental Health, and the nurse practitioner advising her at South Shore Health System, prescribed almost a dozen medications.

He claims they were not listening, as, “She reported that she was ‘feeling afraid as if something awful might happen’ regularly…”

The lawsuit accuses the medical providers of not coordinating Lindsay’s care, saying doctors met with her over video conference instead of in person, sometimes for as little as 17 minutes.

In a statement, Patrick’s attorney told 7NEWS, “…their negligence was beyond tragic. Mr. Clancy intends to hold these professionals accountable.”

7NEWS Legal Analyst Tom Hoopes said the timing of this civil lawsuit is key ahead of her criminal case.

“As it unfolds in the complaint, I think there’s definitely gonna be some sort of sympathy,” said Hoopes. “I think it gives the public a roadmap, a little bit of what they can expect to hear on her behalf of the trials, and I think you’d have to be brain dead not to respond to it. It’s sort of a sad, compelling tale.”

South Shore Hospital responded to the accusations in a statement, writing it, “…cares deeply about and prioritizes the safety of our patients and their families and always strives to provide excellent care.”

7NEWS has reached out to Aster Mental Health but has not heard back.

Lindsay Clancy’s trial is set to begin in July.
