A student in his eleventh year in school submitted a short story for his English class with a teenager protagonist massacring "his own peers in a rampage and kills himself." Two months after writing the story, the boy then made his story real by stabbing a female student in May 2012.

In a report from the Courier Mail, Barrister Mark Johnson, who represents the boy described him as a good and intelligent child. According to Mr Johnson, the boy was raised by very good parents whom saw no indication that their son had a disturbing obsession for committing crime.

Mr Johnson explained that his client's behaviour was provoked by severe anxiety caused by his failure to be chosen as one of the school's "first 15" sports team.

However, Justice Byrne of the Brisbane court said that the boy's act of dragging his small young victim when she tried to escape and his declaration to "finish her off" before killing his other classmates only revealed that the boy is violent to his core.

Mr Byrne said, "Even your own parents saw no sign of your lethal potential. This is terrifying. That someone would take weapons to school and attack indiscriminately for no reason. You have shown what you are capable of."

Prosecutor Michael Lehane submitted a pre-sentence report to the court detailing the boy's fantasy of walking around the school grounds, holding three knives and a hammer with the intention of killing as many of his schoolmates as he could and then will commit suicide.

Also, it was revealed from the report of Mr Lehane that the boy had once killed a neighbour's dog and that he is fond of watching real-life executions video from the Internet.

On the day of the boy's attack to the girl, the boy wore black sunglasses as he entered the girls' toilet. He stabbed his victim in the head, neck, body, arms and hands. The victim tried to escape the boy but she was dragged back into the toilet and was stabbed 12 times more.

Surprisingly, the boy casually walked into a local police station after his deed and surrendered himself to the police.

As for the victim, the court said she survived the attack but she is still under severe emotional and psychological trauma for being attacked by a boy that she does not even know of.
