A New York City judge has found Dimone Fleming not guilty by reason of mental disease or defect in the 2022 killings of her two young sons, drawing comparisons to the ongoing trial of Lindsay Clancy in Massachusetts whose jury is currently deliberating.
Fleming, now 26, killed her sons Octavius Canada, 11 months, and Daishawn Fleming, 3, on November 26, 2022, at a family shelter. Police found her naked from the waist up, pretending to read a children's book that was upside down. Court documents show she had been seen at Floating Hospital in Queens and diagnosed with major depressive disorder, for which she was prescribed medication. Instead of taking her prescription, Fleming used marijuana daily, according to records presented during her proceedings.
What the Right Is Saying
Critics of insanity defenses in cases involving harm to children argue that the legal threshold for criminal responsibility should protect communities from dangerous individuals regardless of mental health history. They note that Fleming's case involved repeated stabbing before submersion in a bathtub, actions they describe as requiring some form of planning.
Some conservative legal commentators have questioned whether the insanity defense is being applied too broadly, arguing that courts must distinguish between defendants who genuinely cannot understand their actions and those who may use mental health diagnoses strategically. The prosecution in Fleming's case contested her mental state at the time of the killings, though the judge ultimately accepted the insanity finding.
In the Clancy case, prosecutors have argued that her actions demonstrate deliberate planning and clear awareness of right versus wrong. They note she researched methods online before killing her children and left notes explaining her decisions. The prosecution contends this premeditation undermines any claim of legal insanity.
"The law requires proof that a defendant did not know the nature or quality of their acts," prosecutors have argued in filings. "These cases present very different fact patterns."
What the Left Is Saying
Mental health advocates argue Fleming's case illustrates systemic failures in treating postpartum depression and maternal psychosis. They point to her diagnosis and prescribed medications as evidence that she sought help but did not receive adequate monitoring or support.
Defense psychiatrists testified that Fleming believed her actions were necessary to "cleanse" her children, a symptom consistent with severe postpartum psychosis. Dr. Eric Goldsmith, who examined Fleming for the prosecution, confirmed she was "grossly psychotic and out of touch with reality" the night of the killings and had been hallucinating, believing she was inhabited by another spirit and that the world was ending.
Progressive groups have argued that criminalizing mental illness rather than treating it fails to protect families. The National Institute of Mental Health estimates postpartum psychosis affects approximately 1 to 2 per 1,000 mothers who give birth, with symptoms including hallucinations, delusions, and confusion.
"These are medical conditions," advocates have stated in court filings. "The appropriate response is treatment, not execution."
What the Numbers Show
According to data from the National Association of State Mental Health Program Directors, approximately 4% of felony defendants nationwide successfully raise an insanity defense, with success rates varying significantly by jurisdiction and case type.
The American Psychiatric Association notes that postpartum psychosis has a recurrence rate of approximately 50% in subsequent pregnancies without treatment. Treatment typically involves hospitalization, antipsychotic medications, and ongoing psychiatric support.
Court records indicate Fleming had been under medical care for several months before the killings. Clancy similarly had spent months visiting various doctors' offices and was prescribed multiple psychiatric medications, though reports indicated she did not take them consistently.
Both cases involve mothers with documented mental health histories who were known to medical providers. Neither case resulted in a death penalty proceeding.
The Bottom Line
The parallel cases of Fleming and Clancy highlight ongoing tensions between mental health advocates and those seeking strict criminal accountability for crimes against children. Fleming's verdict is final, while Clancy's jury continues deliberations with a decision expected Monday.
Both defense teams have centered their arguments on postpartum depression and psychosis as factors that should absolve criminal responsibility. Both prosecutions have emphasized evidence of planning and awareness to argue the defendants understood their actions were wrong.
Legal analysts expect these cases will inform future discussions about how courts should handle maternal mental health defenses, particularly regarding whether current legal standards for insanity adequately account for psychiatric conditions specific to new mothers.
