Australia’s youngest-ever killer allegedly began planning a horrific mass murder after growing ‘bored’ over his failure to lose his virginity during a short period of freedom.
Known only as SLD, the monster was granted lifelong anonymity after stabbing a three-year-old girl through the heart at just 13, and was released in March after more than two decades behind bars.
But Daily Mail can exclusively reveal that during his brief release into the community, SLD became ‘increasingly frustrated’ that his long obsession with finding a girlfriend and having sex remained unfulfilled.
It was then he allegedly plotted an act of extreme violence against an entire neighbourhood of families to relieve his boredom.
Sources close to the convicted murderer said the chilling plan was discovered by chance before it could be carried out, sparking an immediate investigation and his return to custody.
‘SLD’ was just 13 when he murdered toddler Courtney Morley-Clarke in January 2001 on the NSW Central Coast after creeping into her house to steal her brother’s video games.
Prior to his release authorities believed he was at high risk of re-offending because of his obsession with finding a girlfriend and starting a sexual relationship after being locked up behind bars for more than 20 years.
Despite some disturbing concerns and expert warnings, he was still released on a supervision order.
Less than a month later Daily Mail revealed the twisted killer was arrested and charged with five offences – four of which breached his supervision order and one possessing child abuse material.

SLD is due to front court on this matter on December 3, however the previous four charges for breeching his supervision order have now been increased to nine charges.
One order of possessing child abuse material remains in place.
Daily Mail understands that it was during an electronic device check that the disturbing material was found.
It was that discovery that led to an immediate search of his room where a balaclava and a knife were discovered.
According to our sources SLD later admitted to a depraved plan of going house to house in a nearby neighbourhood in Sydney’s western suburbs where he would butcher each family member as he went.
He had no plans of stopping until he was caught.
Prior to his release SLD attended a two-day hearing, where psychiatrists said the killer, was fixated on getting revenge for perceived wrongs and could react violently if he felt he was unfairly treated.
But they also said that keeping him in jail would be detrimental to his mental health and his ability to assimilate into the community later on.

Justice Mark Ierace agreed to his release but said the situation was unusual.
‘It goes without saying this is a very challenging case,’ he said. ‘He has only been out in the community for four months since he was only 13 years old.’
Justice Ierace had options to impose a continuing detention order to keep him behind bars for another 12 months, or granting the extended supervision order.
While there are conditions around his release, SLD has previously admitted that he would be prepared to kill again if something ‘big’ took place.
In a chilling warning, he added: ‘If I kill someone, it won’t be a child.’
His frightening confession and string of violent offences, which includes choking a nurse while jailed, were all considered by Justice Ierace.
After SLD was last released in September 2023, he was back behind bars after just a few weeks later when he was caught approaching women with young children at Bulli Beach in Wollongong, NSW asking them for a date.
He was also found to be accessing pornography online and psychologists warned he had become obsessed with losing his virginity after growing up in jail.

SLD had been adopted at the age of four by a family in Point Clare on the Central Coast, but his murder trial heard he remained ‘disturbed’ despite his new home.
At age 13 years and 10 months, he snatched Courtney from her bed in the night and stabbed her through the heart before leaving her body in long grass 300m from her home.
He was caught after it was noticed that he had gone missing from his residence on the morning the three-year-old vanished.
He initially lied about the crime, leading police on a wild goose chase before later admitting he killed her.
Psychiatric assessments of the teen determined he’d never become a functioning social adult.
He was sentenced to 20 years behind bars in August 2002 and was first released in September 2023.
On October 25 2023, SLD went to Bulli Beach near Wollongong with a supervisor and was spotted by an off-duty prison officer who noticed his electronic monitoring anklet.
The officer witnessed SLD approach a woman with a young girl, and then approach another mother washing an infant at the beach showers.Â

Both women picked up their children and walked away from SLD.
He then entered the Bulli Beach Café and struck up a conversation with a woman feeding an infant.
He allegedly said to the woman: ‘I just got out of jail. Do you come here often?’, followed by: ‘I’ve only been here twice.’
Police then arrived and arrested SLD, who told Wollongong Local Court the next day the encounters were ‘incidental’.
SLD was found guilty of one count of failing to comply with an extended supervision order, which barred him from having contact with children.
He had also tried to access the internet, dating sites and encrypted chat apps.
