Defense Rests Following Key Psychiatric Testimony
The murder trial of Lindsay Clancy, the Duxbury mother accused of killing her three children in January 2023, reached a procedural turning point on Friday as the defense officially rested its case. The final witness, renowned forensic psychiatrist Dr. Phillip Resnick, provided testimony via Zoom, arguing that Clancy was suffering from severe postpartum psychosis at the time of the killings.
Dr. Resnick, who previously testified in the high-profile Andrea Yates case, informed the jury that he concluded Clancy was “clearly psychotic” on the day of the incident. He described her mental state as being under the influence of “command hallucinations,” stating, “It was almost like she was a puppet and someone else was pulling the strings.” According to Resnick, Clancy believed she was acting in her children’s best interest by preventing them from suffering a future without her care.

Prosecution Challenges Insanity Claim
Following the defense’s conclusion, the prosecution immediately began calling rebuttal witnesses, starting with psychiatrist Dr. Avram Mack. Prosecutors have consistently challenged the claim of criminal irresponsibility, arguing that the acts were planned. During cross-examination of Dr. Resnick, prosecutor Jennifer Sprague questioned the validity of command hallucinations as a defense, referencing Resnick’s own published work, “Faking It,” which notes that such hallucinations can be fabricated.
The prosecution also contested aspects of the defense’s narrative, pointing to hospital records that allegedly show Clancy expressing future aspirations, such as becoming an advocate for postpartum issues, rather than only exhibiting the “muted” or “matter-of-fact” behavior described by the defense’s expert. The court is currently weighing whether involuntary manslaughter should be included as a potential verdict option alongside first-degree and second-degree murder charges.
Legal Stakes and Next Steps
The jury’s verdict will hinge on whether they accept the insanity defense. If found guilty of first-degree murder, Clancy faces life imprisonment without the possibility of parole. If the jury determines she was not criminally responsible due to mental illness, she would be committed to a state psychiatric hospital. The trial is now moving toward closing arguments, which Judge Sullivan indicated could begin as early as Monday or Tuesday, depending on the duration of the prosecution’s rebuttal phase.
