Australian Mother Not Criminally Responsible for Sons' Murders Due to Mental State

A woman in New South Wales, Australia, will not face criminal charges for the murders of her two sons, aged nine and 11, after a court determined she was suffering from major depression at the time of the killings in September 2024.

The woman, whose identity is protected by legal order, had pleaded not guilty to two counts of domestic violence murder. She was taken to a hospital with self-inflicted injuries following the incident.

During a recent NSW Supreme Court hearing, evidence presented included a letter from the woman expressing a desire for forgiveness and stating she could not leave her children without her support in a troubled world. In the month leading up to the deaths, she conducted internet searches related to murder, suicide, affairs, divorce, and harming children.

The court heard that the woman had a positive relationship with her ex-husband but learned in early August that his new partner was pregnant. On the day of the murders, she spent time with her ex-husband and sons and made concerning online searches, including one about when a coroner becomes involved.

Later that evening, she sent her ex-husband a goodnight message and searched online for statistics on parental child homicides in Australia. Sometime that night, she killed the boys and inflicted injuries upon herself.

Their father discovered the children's bodies the following afternoon after being alerted to their absence from school. He found the woman in a semi-conscious state and, upon asking what had happened, she responded, "I killed them." He then contacted emergency services.

In psychiatric evaluations following the murders, the woman reportedly told a psychiatrist that she believed if her children died, "then nothing could go wrong with them."

Justice Richard Cavanagh ruled that while the woman did cause the deaths of her children, she was not criminally responsible due to her mental health condition. This finding was supported by three psychiatric experts who testified that the woman was experiencing major depression and was unaware her actions were wrong. One expert also noted that the woman had experienced "nihilism which completely distorted her judgement about the future."

"Having regard to the updated reports of the psychiatric experts … I'm satisfied that at the time of killing her two children, the accused did not know that the act of stabbing them was wrong, in that she could not reason … as to whether those acts, as perceived by reasonable people, were wrong," Justice Cavanagh stated.

The Director of Public Prosecutions had previously agreed to a special verdict of not guilty by reason of mental impairment. The woman, who appeared in court via audiovisual link, will now be a forensic patient at a facility determined by a mental health tribunal.

Her release into the community will be contingent upon the tribunal determining she no longer poses a danger to herself or others. The NSW Attorney-General and Minister for Health will also have a say in the matter.
