A man accused of killing his fiance's daughter while on a family holiday in the Blue Mountains stole a shotgun and a rifle from a neighbouring property months before she was killed, court documents allege.
Justin Stein, 31, is charged with the murder of Charlise Mutten, whose body was found in a barrel dumped on the banks of the Colo River, west of Sydney, in January.
Almost four months later, homicide detectives visited the ex-tradesman at his cell in Silverwater Jail and charged him with firearm offences after seizing two guns from bushland in February.
Police do not believe the shotgun and rifle were used to kill the Tweed Heads schoolgirl, despite confirming she died from a single gunshot wound.
Mr Stein has also been charged with two counts of possessing child abuse material, which investigators say is not related to the death of the nine-year-old girl.
He did not front Penrith Court today when the prosecutor indicated that 120 items of "significant" new evidence had been seized, including from his electronic devices.
Court documents allege he did "possess … videos that depicted material in a manner that would in all circumstances cause offence to reasonable persons and is a person who is a child in a sexual context".
Lawyer Peter Katsoolis was unable to attend court because he is isolating at home after contracting COVID-19, but appeared on screen before a magistrate.
"We were served further material yesterday — both parties will need time to digest this material," he said.
"There is still some significant outstanding material that remains significant."
Charlise was first reported missing by her mother while they were on holiday at Mr Stein's family home in Mt Wilson.
Court documents allege Mr Stein stole the two guns from a neighbouring home of the property in August last year and is also charged with one count of aggravated break and enter.
A silver serving plate, an electric blanket, a silver gravy boat, knives, forks, binoculars and a silver lighter were among the other items stolen by Mr Stein, who "was in company of another person", court documents allege.
Charlise's disappearance sparked a massive search of bushland and involved hundreds of police, SES and Rural Fire Service volunteers in January.
Many of them described their heartbreak to learn of the tragedy after holding out hope the girl would be found alive.
Mr Stein will remain behind bars before he is due to face Penrith Local Court again on July 15.
