A lawyer for Lindsay Clancy, the Massachusetts mother accused of killing her three children in 2023, has formally denied that she will testify about any homicidal thoughts in the civil lawsuit filed by her estranged husband, Patrick Clancy, against her doctors. In a court filing submitted this week in Plymouth County Superior Court, attorney Kevin Reddington asserted that his client will invoke her Fifth Amendment right against self-incrimination and will not provide deposition testimony regarding her mental state at the time of the alleged crimes. The move effectively blocks a key line of evidence that Patrick Clancy’s legal team had hoped to use to prove that Lindsay Clancy’s physicians failed to properly assess and treat her postpartum mental health condition.
**Context**
The civil suit, filed by Patrick Clancy in early 2024, names several healthcare providers who treated Lindsay Clancy in the months before the deaths of her children — 5-year-old Cora, 3-year-old Dawson, and 8-month-old Callan. The complaint alleges that the doctors and therapists ignored clear warning signs of severe postpartum psychosis, including documented expressions of intrusive thoughts and suicidal ideation, and that their negligence directly contributed to the tragedy. Lindsay Clancy, who has pleaded not guilty by reason of insanity to three counts of murder and other charges in the criminal case, has been held at a state psychiatric facility since her arrest. Her criminal trial is pending, and her legal team has consistently argued that she was suffering from a severe mental health crisis at the time of the killings.
Patrick Clancy’s lawsuit seeks to hold the medical professionals accountable for what he describes as a catastrophic failure to intervene. As part of the discovery process, his attorneys sought to depose Lindsay Clancy about her communications with her doctors, including any statements she made about homicidal thoughts. The deposition was scheduled for late October 2026. In response, Reddington filed a motion to quash the subpoena, arguing that any testimony from Lindsay Clancy about her mental state would inevitably touch on the facts of the criminal case and could be used against her in the murder trial. The filing states that “Ms. Clancy will not waive her constitutional rights and will not provide testimony regarding any alleged homicidal ideation or other mental health symptoms discussed with her treating providers.”
The legal standoff highlights the complex intersection of criminal defense, civil liability, and medical privacy. While Patrick Clancy’s civil case is separate from the criminal proceedings, the two are deeply intertwined. Any admission by Lindsay Clancy in a deposition could be used by prosecutors to challenge her insanity defense. Conversely, if she refuses to testify, the civil plaintiffs may be unable to prove that the doctors had actual knowledge of her dangerous thoughts — a key element in a medical malpractice claim.
**Analysis**
The denial of testimony carries significant implications for both the civil and criminal cases. From a medical-legal perspective, the case has already become a flashpoint in the debate over postpartum mental health screening and the duty of care owed by physicians to patients experiencing psychosis. Experts in forensic psychiatry have noted that the standard of care for postpartum patients includes routine screening for suicidal and homicidal ideation, and that failure to act on reported thoughts can constitute negligence. However, proving that a doctor knew — or should have known — that a patient posed a danger to others often requires direct evidence of what the patient told the clinician. Without Lindsay Clancy’s testimony, Patrick Clancy’s legal team will have to rely on medical records, notes from therapy sessions, and testimony from the doctors themselves, who may be reluctant to admit they missed warning signs.
Moreover, the invocation of the Fifth Amendment in a civil case is a double-edged sword. While it protects Lindsay Clancy from self-incrimination, it also allows the civil jury to draw an adverse inference — that is, they may assume that her testimony would have been damaging to her case. In Massachusetts, as in most states, a party’s refusal to testify in a civil proceeding can be used against them. This could weaken her position in the civil suit, but her primary legal battle remains the criminal case, where the stakes are far higher. Her defense team is likely prioritizing the avoidance of any statement that could undermine the insanity plea.
The broader scientific and medical community is watching closely. The case has already prompted calls for improved postpartum mental health protocols, including mandatory reporting of homicidal ideation and better coordination between obstetricians, psychiatrists, and social workers. Researchers at institutions such as Harvard Medical School and Massachusetts General Hospital have published studies showing that up to 20% of postpartum women experience intrusive thoughts of harming their infants, yet many clinicians lack training on how to assess risk. The Clancy case may accelerate efforts to standardize screening tools and create clear legal obligations for providers.
