Emergency services responded to reports that three children and a woman had been found in a vehicle with stab wounds. Bystanders who arrived first on the scene attempted to perform first aid while contacting triple zero, NSW Police said.
The woman has been charged with murder and two counts of grievous bodily harm with intent to cause murder, according to the Guardian. However, other reports (The Age, Sydney Morning Herald, Brisbane Times) state she was charged with the murder of her five-year-old son and the attempted murder of his two younger siblings. The discrepancy may reflect the precise wording of the charges filed.
The children were reportedly taken to hospital. Their current conditions remain unclear. The woman is expected to face court at a later date.
