A teenager who killed a 10-year-old girl has revealed the nine final words she spoke to her victim after she was spurred on to carry out the attack by a voice in her head. 

The teenager, now aged 15, spoke the haunting phrase before killing the 10-year-old in Gunnedah, north-eastern NSW, on July 8, 2020. 

'Don't worry, darling – I'll make it all go away,' she said.

The NSW Supreme Court found last Tuesday the teenager was not criminally responsible for the murder due to mental illness.

The teenager had revealed her final words to her victim to a psychiatrist who had been hired to assess the mental health of the 15-year-old girl.

The court released the report which found the girl was suffering from untreated schizophrenia which included auditory hallucinations coaxing her to kill and delusions her life and experiences were not real. 

One voice, called 'Rae', had told her to go into her parents room with a knife up her sleeve - the night before she killed the 10-year-old, Daily Telegraph reported.

'Just kill them – think of all the wrongs they have done,' the voice told the girl.

The teenager did not carry out the act and left the room.

The girl claimed she was then visited by another muffled and hoarse voice, called 'Get Them', the following morning.

She said it had urged her to kill the 10-year-old girl at the farmhouse. 

Police bodycam video released by the court showed a detective approaching the teenager at a neighbouring rural property just hours after the gruesome attack. 

In the footage, the plainclothes officer tells the teen police have been informed 'something happened' to a 10-year-old girl that morning. 

'Did you have anything to do with that?' the officer asks her, who then responds. 

'We're going to have to place you under arrest,' he concludes. 

The footage captures the moment the teenager is loaded into the back of a police van and told she will be taken back to Gunnedah. 

A gloved officer is then seen carefully removing each of the teen's black Nike sneakers and placing them into individual paper bags. 

Footage of an interview held just hours later at the Gunnedah Police Station shows the girl seated next to a NSW Ambulance Chaplain who acts as a support person.
