A bombshell claim about another person 'possibly involved' in the murder of Charlise Mutten has been made after the man accused of shooting the nine-year-old and disposing of her body in a barrel appeared in court.
Defence solicitor Peter Katsoolis, who made the claim after appearing for accused murderer Justin Stein on Friday at Penrith Court, also told Nine News he was yet to read a 4000 page police brief on the case and hadn't received a post-mortem report on Charlise's death.
He said 'there is no clear motive' for his client or anyone else to have allegedly killed Charlise and that he had 'a long way to go to analyse all of those movements' in relation to CCTV released by police which allegedly showed Stein driving around with a barrel in the back of his red ute soon after the girl's death.

At the time of the alleged murder, police say Charlise's mother Kallista Mutten was staying at a caravan park at Lower Portland on the Hawkesbury River, 81km from the luxury Mount Wilson estate where Charlise is believed to have died.
Stein was briefly mentioned in Penrith Local Court on Friday morning where he was remanded in custody until May over the murder charge, and a separate charge of breaching parole.
Mr Katsoolis told the court the alleged parole breach related to a drug charge from 2016.
Stein did not appear on screen from Silverwater prison, where he is believed to have been held since his arrest in January.
Magistrate David O'Neil set the next hearing for the murder charge on May 20.

Charlise was allegedly fatally shot with a 'small calibre rifle' sometime between January 10 and 11.
The Tweed Heads schoolgirl had been holidaying with her mother and Stein at his family's luxury Blue Mountains wedding venue and at a Lower Portland caravan Park over the Christmas holiday season.
Ms Mutten reported her daughter missing from the Wildenstein property on the morning of January 14, and police located her remains inside a blue barrel 65km on the banks of the Colo River on the afternoon of January 18.

Stein was arrested on the same night and charged with Charlise's alleged murder.
An autopsy on the remains of Charlise revealed the cause of death and detectives released CCTV footage last month which allegedly shows Stein's red Holden Colorado ute with a barrel-shaped object in the back under a blue tarpaulin towing a white boat around various Sydney locations.
Police allege Stein was behind the wheel when the red ute visited the BP service station at Marsden Park, in northwestern Sydney at 5.53pm on Thursday, January 13.
It was then captured driving along Victoria and Bayswater roads at Drummoyne around 7.20pm when Stein allegedly drove it to Five Dock boat ramp.
Ms Mutten, 31, is now reportedly pregnant with Stein's child.
