After an emotionally charged five-week trial, jurors were unable to unanimously decide whether Ms. Clancy murdered her three children with conscious premeditation or was legally insane. Judge William Sullivan declared a mistrial after the jury foreperson reported they were deadlocked.<\/p>\n
The defense called two experts and the prosecution three rebuttal experts. Forensic psychologist<\/a> Dr. Paul Zeizel was the first defense witness. His evaluation began only 11 days after the killings. He interviewed Ms. Clancy 45 times. Over 35 hours, he reconstructed Ms. Clancy\u2019s depression<\/a>, mood instability, and postpartum<\/a> psychosis<\/a>. She believed strangers could read her thoughts. She felt compelled to kill the children and herself. During a phone call to her husband, Dr. Zeizel heard her tell him that a male voice commanded her to kill the children. He diagnosed Ms. Clancy with postpartum psychosis and bipolar<\/a> II disorder, concluding that a mental disorder impaired her ability to appreciate the moral wrongfulness of her actions.<\/p>\n Defense forensic psychiatrist Dr. Phillip Resnick, an expert on maternal filicide, examined Ms. Clancy four months after the killings for three hours. He diagnosed severe depression, bipolar II disorder, suicidal<\/a> intent, and postpartum psychosis, manifested by a command hallucination. She was preoccupied with her children\u2019s welfare, believing they could not live without her, which is characteristic of altruistic<\/a> filicide. He described her as a puppet on a string and concluded that impaired judgment and reality testing contributed to the killings.<\/p>\n The prosecution called three experts. Two of them, psychologist Dr. Kirk Heilbrun and psychiatrist Dr. Avram Mack, interviewed the defendant together and apart for about 13 hours over three days, three years after the killings.<\/p>\n Dr. Heilbrun concluded that Ms. Clancy was suicidal and did not want to leave her children behind. Although he characterized the killings as \u201caltruistic filicide,\u201d he concluded her state of mind did not prevent her from recognizing her actions were wrong.<\/p>\n Dr. Avram Mack opined that Ms. Clancy suffered major depression, but not postpartum psychosis. Although acknowledging a hallucination, he noted this does not necessarily establish a psychotic disorder. He concluded she retained the ability to understand the wrongfulness of her actions.<\/p>\n Psychiatrist Dr. Gregory Saathoff, the third prosecution witness, opined that Ms. Clancy was purposeful in her suicide plan, evidenced by a normal conversation with her husband before the stabbings. He believed her filicidal motivations were not caused by a one-time command hallucination, which is rare, and concluded she was sane at the time of the killings.<\/p>\n What I found most illuminating about the expert testimony was not what was said, but what was missing: a careful inquiry into Ms. Clancy\u2019s emotions and thoughts while the killings took place. Among the experts, Dr. Zeizel was in the unique position to closely examine the defendant\u2019s thinking before it was potentially contaminated by time and defensive reasoning, as he examined her days after the killings. During his testimony, Dr. Zeizel outlined her thinking difficulties, such as her reported hallucination, and her delusional belief that others were reading her mind. However, he did not provide direct evidence of a connection between her thinking distortions and the strangulations. This nexus is crucial, as the assessment of her thoughts at the time of the killings is the required cognitive prong of the insanity defense, with mental disease being the other prong. Her thought processes and content during the killings are decisive, as the law states that a defendant must lack a substantial capacity to understand that the act was against the law or common moral principles.<\/p>\n Did Dr. Zeizel ask Ms. Clancy directly about her thoughts when she was strangling the children? Did he ask, \u201cWhat was going through your mind\u201d during the killings, for instance? She commented to a hospital chaplain immediately after the stabbings, \u201cI am so glad my children are safe.” What exactly was she thinking about the strangulations when she made that comment? Were the killings in response to a burning resentment of her children, as the prosecution alleged, or was she driven to protect them from some sinister fate? A probing exploration of her thinking might have led to a linkage between her thinking and its degree of reality distortion that is crucial to the insanity defense.<\/p>\n
