Police in Sydney are investigating the stabbing deaths of a child and two injured siblings, which occurred on Sunday afternoon in the Blue Mountains. The mother involved is expected to face charges for murder and attempted murder, with self-inflicted stab wounds reported as well. This incident follows three other domestic violence-related fatalities over the weekend across New South Wales, prompting police and advocacy groups to call for increased government resources and federal funding to address the crisis of domestic violence in Australia.

Story summary
In September 2024, a 42-year-old woman from the Blue Mountains was found not criminally responsible for stabbing her two sons to death. The boys were aged nine and eleven when their father discovered them in their family home. Before the incident, she had been struggling with major depression and made several disturbing internet searches related to suicide and killing children. These searches included queries like "Most Infamous Alleged Mommy Murderers in History" and "How To Respond When Your Child Says 'I hate you'."
The court ruled that due to her mental health condition, the woman was unable to reason at the time of the murders. She had been under significant stress after learning that her ex-husband's new partner was pregnant. Following the tragic deaths, she attempted to take her own life and was hospitalized with self-inflicted injuries.
Currently, the Mental Health Review Tribunal will determine where she will be detained for further treatment.
