Bronx judge rules mother not criminally responsible for stabbing deaths of two young children, citing postpartum psychosis

 August 30, 2026

A Bronx judge has found Dimone Fleming not guilty by reason of mental disease or defect in the stabbing deaths of her two young children, a decision sparking debate over mental health defenses and the limits of accountability in New York’s justice system.

Dimone Fleming, 26, stood accused of killing her 3-year-old son Daishawn Fleming and 11-month-old son Octavius Canada inside her Bronx family shelter apartment in November 2022. Police found the children’s bodies beneath a pile of clothes in a bathtub, after Fleming had already been taken to a hospital for psychiatric evaluation. The tragedy unfolded after a shelter employee called 911 to report water and smoke coming from Fleming’s unit, prompting police to intervene when they found her “acting irrationally.” Later, the children’s father, Columbus Canada, discovered his sons unresponsive and called authorities.

The case turned on Fleming’s mental state. Both prosecution and defense psychiatrists concluded she was in the grip of a severe psychotic episode, described by Dr. Eric Goldsmith as “grossly psychotic and out of touch with reality,” hallucinating and convinced a spirit had invaded her body. A forensic psychiatrist’s report from the defense stated, “Ms. Fleming believed her actions were necessary to protect or ‘cleanse’ her children.” Court records also show Fleming had been treated for major depressive disorder at a Queens hospital for two months before the killings and was prescribed psychotropic medication. Family members told AP News and Fox News that she suffered from postpartum depression, wanted treatment, and had recently become obsessed with the idea her children were demons.

Police sources quoted by The Post reportedly said Fleming confessed to killing her sons and made references to the “devil” during interviews with detectives. As the New York Post reported, Fleming was originally charged with first-degree murder, but the psychiatric evaluations ordered by both prosecution and defense ultimately led the court to find her not responsible by reason of mental disease or defect. She remains in custody and will be reevaluated by court-appointed psychiatrists, with her next court appearance scheduled for September 18. The judge is expected to determine whether Fleming continues to pose a risk to others and what further steps will follow. Despite the verdict, Fleming could now face months or even years of hospitalization.

Controversy over mental illness defenses in child deaths

As with other high-profile cases involving mothers who kill their children while suffering from apparent psychosis, Fleming’s ruling has intensified public debate about justice, mental health, and the limits of punishment. Bronx Assistant District Attorney Tiffany Wichman acknowledged the limits of prosecution in such cases, stating, “Prosecuting mothers does not and cannot prevent these crimes from happening, but public discourse might.” She added, “People talking about it is important, and I hope people continue talking about it.”

Fleming’s family members and the children’s father painted a portrait of a troubled but loving mother. “She’s a good person,” said Columbus Canada. “She was a loving person. She loved kids.” Her relatives described her downward spiral: “She thought the kids were devils. She said she was afraid of them,” said Casey Canada, the children’s great-aunt, in comments to AP News. Fleming’s father, Dwane Fleming, told Fox News that she had sought treatment for her mental health struggles.

The Fleming case closely mirrors the ongoing Massachusetts trial of Lindsay Clancy, a former nurse accused of strangling her three children and attempting suicide. Like Fleming, Clancy seeks a not-guilty-by-reason-of-insanity verdict, raising fresh questions about how far the justice system should go in excusing violent acts when mothers are found to be suffering from severe postpartum psychosis. These cases have drawn national attention and have been referenced in discussions of the insanity defense and its limits.

The court’s decision has drawn scrutiny from New Yorkers already skeptical of a softening criminal justice system. It comes amid a string of recent high-profile cases, including controversial pardons and lenient rulings, that have left many questioning whether the current system adequately balances compassion for the mentally ill with public safety and justice for victims. Similar debates arose in cases such as the pardon of a convicted child sex offender and the DOJ’s denaturalization effort targeting criminals who had evaded justice. In New York, lenient responses to violent crime have become part of a larger pattern, as seen in stories like the controversial handling of accused killers at Rikers. The Fleming verdict is now the latest flashpoint.

Justice or excuse? New York’s system faces hard questions

For many, the tragedy at the Bronx shelter is a reminder of the need for robust mental health care and early intervention, especially for mothers at risk of postpartum psychosis. For others, it’s a warning that the criminal justice system is drifting too far from accountability, excusing heinous acts that destroy families and communities. As the legal process continues, Fleming is not slated for release. The judge will decide in September whether she remains a danger to others, and whether further hospitalization or other measures are warranted, a process that could stretch on for years.

For readers following the evolution of criminal responsibility in our courts, the Fleming case joins a growing list of cases where mental illness is used as a shield against punishment. Other recent headlines, from similar Bronx verdicts involving postpartum psychosis to federal efforts to deport violent offenders, underscore the stakes when the system hesitates to draw a clear line.

In the end, justice cannot work if accountability disappears whenever bureaucracy or experts say so. Families and victims deserve better than a shrug and a diagnosis.
