The prosecution’s final rebuttal witnesses attempted to cast doubt on Lindsay Clancy’s postpartum psychosis diagnosis on Tuesday. They asserted that she was not hearing voices; therefore, she is criminally responsible for the deaths of her three young children.

Recap of Dr. Kirk Heilbrun’s Testimony

As we enter the final days of trial, prosecutors began calling rebuttal witnesses. Dr. Kirk Heilbrun testified Friday following the defense’s rest and continued into Monday. His testimony led defense attorney Kevin Reddington to file a motion for a mistrial after religion was brought into the manner. 

Heilbrun corroborated the prosecution’s theory that Clancy premeditated the murders and was not suffering from anything more than depression and anxiety. He said that she did not have the medical history to back up her claims, but that may have been due to the lack of care she received. He also does not believe she was hallucinating or hearing voices.

“Everything I did as part of this evaluation, the evidence much more strongly, in my opinion, supported the second explanation, which was the serious suicide attempt accompanied by killing the children out of love,” Heilbrun said.

Clancy sought help in more ways than one. She took the medications, she visited the doctor, she called suicide hotlines, she admitted herself into a psychiatric facility, but she was not provided proper care, and in some cases was turned away.

Lindsay Clancy Was an Incredible Mother

Reddington challenged Heilbrun’s testimony, suggesting that he made up his mind before interviewing Clancy at the state hospital in Tewksbury. “Would you agree with me, sir, that before you met with Lindsay in Tewksbury, you pretty much had an idea this woman was a beast, killed her three kids, didn’t you?” Reddington asked.

Heilbrun disagreed, and said he “did his best to have an open mind.” Reddington then noted that previous character witnesses and testimony said that Clancy was “an incredible mother taking care of her kids.“

“Bringing her life experience, which you’ve testified yesterday, that she never had any abuse in her life, was raised by loving mother and father, good student, hard worker, great mother, good friend, wonderful wife,” Reddington said. “She then randomly decides to kill her children by strangling them. Those are the facts we’re dealing with?“

Final Conclusion

Heilbrun’s final conclusion was that Clancy was “criminally responsible” for the deaths of her children. “She retained an awareness of the illegality of killing others, including her children,” he said. “Her moral awareness of this killing was influenced by her strong desire to die and, if she was dead, not to leave her children behind.”

He found that she had a set of choices that she coherently made, rather than what the defense claims: that she was not involved in the decision-making. “This is difficult but important to say. There are many ongoing decisions that have to be made to accomplish a killing like this in 18 to 20 minutes,” Heilbrun said. 

“For example, why the basement? Who among the children goes first? What do you say to the kids to keep them from panicking?“

Witness Testifies to The Voice

A forensic psychiatrist at the University of Virginia and a senior psychiatrist for the FBI’s Behavioral Analysis Unit testified Tuesday that Clancy said during two video interviews that she began hearing voices on January 24, 2023. 

Dr. Gregory Saathoff said the mother told him her then-husband, Patrick Clancy, called her while out running errands and the voice she heard did not stop until she strangled all three of her children in the basement of their Duxbury, Massachusetts home with exercise bands. Afterward, she supposedly cut her wrists and neck before leaping out a second-story window.

Prosecutors have argued that Clancy did not intend to kill herself, and that she lowered herself out the window. However, Saathoff testified on Wednesday morning that the attempt was very serious, and just because the lacerations were not deep does not mean she did not have the intention of dying.

Fate of Lindsay Clancy

Clancy’s defense does not dispute that she killed her children, but argues that she was suffering from postpartum psychosis and should not be held criminally responsible. The rare mental illness is linked to stress and sleep deprivation, and can cause hallucinations. 

Clancy has pleaded not guilty to the murder charges. If she is found guilty, she could face life in prison. But if she is found not criminally responsible, or not guilty by reason of insanity, she will be committed to a psychiatric facility where she will receive continued mental health care.
