The four suspects who allegedly killed 15-year-old Noongar boy Cassius Turvey in Perth appeared in WA's Supreme Court via video link from prison Wednesday morning.
Jack Brearley, Aleesha Gilmore, Brodie Palmer, and Mitchell Forth remained silent during the proceedings.
Each face a string of charges including the murder of Cassius.
Brearley, who was the first of the four to be charged, is accused of murder, stealing, unlawful assault causing bodily harm with circumstances of aggravation, unlawful wounding in circumstances of aggravation, and detaining another person with an intent to compel them to do an action.
Brearley allegedly attacked both Cassius, aged 15, and another boy aged 13 on the same day.
Gilmore, Palmer and Forth also stand accused of murder, having been charged in January this year over the attack in October which left Cassius fatally injured.
The four accused have been charged with further offences since.
On Wednesday their cases were adjourned and they continue to be remanded in custody until their next court appearance on 24 May.
While Brearley's lawyer stated his client was ready to face trial, an near-eight week adjournment was deemed necessary so the other three suspects are prepared.
None of the four have entered a plea to any of the charges.
