The five-year-old boy died at the scene while his siblings were seriously injured along with their 42-year-old mother in Valley Heights near Springwood on Sunday afternoon. NSW Police Deputy Commissioner Peter McKenna stated that all four individuals found in a parked car are family members, and investigations continue into this tragic event which occurred alongside other domestic violence fatalities over the weekend in New South Wales.

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.
