The four people accused of murdering schoolboy Cassius Turvey have made their first appearance together in a Perth court on all the charges they are facing.
WARNING: Aboriginal and Torres Strait Islander readers are advised this article contains an image of a person who has died.
These include accusations three of them were involved in detaining and assaulting another teenager in the days before Cassius was allegedly fatally attacked with a metal pole.
Jack Brearley, 22, Mitchell Colin Forth, 24, Aleesha Gilmore, 21, and Brodie Lee Palmer, 27, all appeared in the Stirling Gardens Magistrates Court via video link from the different prisons they have been held in since their arrest.
Mr Brearley appeared from Casuarina Prison, Ms Gilmore from Greenough Regional Prison in WA's Mid West, and Mr Forth and Mr Palmer from Hakea Prison.
Mr Brearley has been in custody the longest because he was charged with Cassius's murder just after the 15-year-old died in hospital from his injuries in October last year.
He is also accused of attacking another 13-year-old boy who was with Cassius, and stealing his crutches and cap.
Mr Forth, Ms Gilmore and Mr Palmer were not charged with the teenager's murder until January this year, when they were all taken into custody.
It is alleged they were involved in the bashing of Cassius with what's believed to be a shopping trolley handle, as he walked with friends in the eastern Perth suburb of Middle Swan.
Three of them — Mr Brearley, Ms Gilmore, and Mr Forth — were then charged in late January with further offences over the alleged kidnapping and assault of another 15-year-old boy in Perth's eastern suburbs.
In a statement at the time, police allege that boy was punched, kicked, stabbed and held against his will.
That attack is alleged to have happened four days before the fatal incident involving Cassius.
All of the accused initially appeared in the Midland Magistrates Court on those charges, but they have now been joined up with the murder allegation that the three, and Mr Palmer, are facing.
On Wednesday all of their cases were adjourned until late May and they were again remanded in custody, as state prosecutors continue to disclose evidence in the case to their lawyers.
None of them have so far been required to plead to any of the charges against them, but at his very first court appearance in January, the lawyer for Brodie Palmer foreshadowed a not guilty plea on behalf of his client.
The court heard that because Mr Brearley was charged with murder well before his co- accused, he was ready to have his case committed to the Supreme Court for trial.
But because the other three accused were not ready for that, the eight-week adjournment was needed.
There have been no bail applications by any of the accused, but if that was to happen, they would need to make an application to the Supreme Court because only a justice of that court can approve bail for people charged with murder.
