A Massachusetts mother accused of murdering her three young children broke down in tears in a Dedham courtroom today as a forensic pathologist detailed the harrowing final moments of her victims, describing how the children were strangled with exercise bands and remained conscious for only seconds before losing consciousness.
Lindsay Clancy, 32, sobbed quietly at the defense table as Dr. William Zane, a prominent forensic pathologist testifying for the prosecution, provided a clinical yet devastating account of the strangulation injuries that killed five-year-old Cora, three-year-old Dawson, and eight-month-old Callan in their Duxbury home on January 24, 2023.
The testimony came during a critical hearing in Norfolk Superior Court, where Clancy faces three counts of first-degree murder and multiple other charges. The former labor and delivery nurse has pleaded not guilty by reason of insanity, with her legal team arguing she suffered from severe postpartum psychosis at the time of the killings.
Dr. Zane, who examined the children’s bodies and reviewed autopsy reports, testified that the ligature strangulation using elastic resistance bands caused a rapid and complete compression of the jugular veins, leading to unconsciousness within four to ten seconds.
“These were elastic round loops that were put around the neck, somewhat tightly pinching the skin,” Dr. Zane said, describing the injuries he observed. “You could see little lines where the skin was pinched.
It just stays there. It’s an immediate compression of those two veins, staying there, and then death occurs minutes later.”
The pathologist’s testimony became particularly contentious when defense attorney Kevin Reddington confronted him about previous statements made in a 2011 Rhode Island case involving manual strangulation. Reddington pressed Dr. Zane on apparent inconsistencies regarding the timeline of death by strangulation.
“In that case, you testified that it would take 10 to 20 seconds for unconsciousness to occur, and then two to three more minutes of continuous pressure for death,” Reddington said, reading from a transcript of the earlier trial. “Is that still your medical knowledge?”
Dr. Zane pushed back, emphasizing the critical distinction between manual and ligature strangulation. He explained that manual strangulation, using hands, often involves inconsistent pressure as victims struggle, potentially prolonging the process.
Ligature strangulation, he said, is fundamentally different.
“Wrapping a round loop resistance band, which is a ligature, immediately compresses those vessels,” Dr. Zane testified. “There’s no coming off.
There’s no putting back on. It’s a very complete, one-time, immediate, non-varying compression.”
The distinction proved crucial to the prosecution’s case, as it suggested a deliberate and sustained act rather than a momentary loss of control. Dr. Zane confirmed that the bands were wrapped around each child’s neck multiple times, securing them in place without requiring the perpetrator to remain present.
“The important part to me was they were wrapped several times,” Dr. Zane said. “Whether it had a bow or a knot would not really be important.
It was secure and wrapped around the neck several times.”
When asked whether the bands required someone to stand over the body and continuously apply pressure, Dr. Zane replied, “No. In this case, these were elastic round loops that were put around the neck, somewhat tightly pinching the skin.
It just stays there.”
The courtroom atmosphere grew tense as the pathologist detailed the physiological process of death by ligature strangulation. He explained that the bands blocked the jugular veins, preventing deoxygenated blood from leaving the brain while the carotid arteries continued pumping oxygenated blood into it.
“You become unconscious within five to ten seconds, but then with continued pressure, your brain dies,” Dr. Zane said, his voice steady and clinical despite the gravity of his words. “The continued constriction of the blood flow has to be still continuously applied for the brain to die.”
Clancy, dressed in a gray blouse with her hair pulled back, appeared visibly distressed throughout the testimony. She wiped tears from her eyes as the doctor described the final moments of her children’s lives, occasionally shaking her head as the details emerged.
The defense has argued that Clancy was in the throes of severe postpartum psychosis, a condition that can cause hallucinations, delusions, and irrational behavior. They contend she was not criminally responsible for her actions at the time of the killings.
Prosecutors, however, maintain that Clancy’s actions were calculated and deliberate. They point to evidence that she researched methods of killing on her phone in the days leading up to the deaths and that she attempted suicide after the attacks by jumping from a second-story window.
Dr. Zane’s testimony also addressed the timeline of death, clarifying that while unconsciousness occurs rapidly, brain death requires several minutes of sustained pressure. “You become unconscious within five to ten seconds, and then death within five to ten minutes after that with continuous pressure,” he said.
The pathologist’s detailed explanation appeared to counter defense suggestions that the children might have died quickly, potentially mitigating Clancy’s culpability. Instead, his testimony painted a picture of a prolonged, deliberate process.
During cross-examination, Reddington attempted to challenge Dr. Zane’s credibility by highlighting his previous testimony in the Rhode Island case, where he had stated that manual strangulation could take up to 20 seconds to cause unconsciousness and require two to three minutes of continuous pressure for death.
“You have no memory of that?” Reddington asked after reading from the 2011 transcript.
“I have no memory of that. I’m sure you’re reading it correctly,” Dr. Zane replied, adding that his medical knowledge remained consistent but that the mechanisms of injury were entirely different.
The judge, Beverly Cannone, intervened several times to clarify the line of questioning, allowing the defense to pursue the inconsistency but ultimately permitting Dr. Zane to explain the distinction between the two types of strangulation.
“The Fry case that’s coming back to me a little now, that was a manual strangulation and also a body compression, which is a totally different type of asphyxia,” Dr. Zane said, referring to the 2011 case.
The testimony continued for several hours, with Dr. Zane remaining composed under intense questioning. At one point, he demonstrated how the exercise bands would have been wrapped around the children’s necks, noting that they left distinctive marks on the skin.
“I could tell from the appearance of the skin on the neck that the band was wrapped around the child’s neck several times and then left there,” he said.
The hearing is expected to continue for several more days, with additional expert witnesses scheduled to testify about Clancy’s mental state at the time of the killings. The case has drawn national attention, highlighting the devastating consequences of untreated postpartum mental illness.
Clancy’s husband, Patrick Clancy, has publicly supported his wife, stating that she was a loving mother who suffered from severe postpartum depression and psychosis. He has urged the public to understand the complexities of the condition rather than rush to judgment.
The prosecution, however, has focused on the forensic evidence, arguing that the method of killing demonstrates intent and deliberation. Dr. Zane’s testimony today reinforced that narrative, emphasizing the sustained nature of the strangulation.
As the court adjourned for the day, Clancy was led away in handcuffs, her face still streaked with tears. The trial is expected to last several weeks, with a jury ultimately deciding whether she was legally insane at the time of the killings or criminally responsible for the deaths of her three children.
The case continues to resonate across the country, sparking discussions about maternal mental health, the criminal justice system’s treatment of postpartum psychosis, and the limits of the insanity defense. For now, the courtroom remains a space of raw emotion and stark medical testimony, as both sides prepare for the next phase of this tragic and complex case.
