Mum of slain Charlise Mutten spared jail

The mother of murdered nine-year-old Charlise Mutten has been convicted but spared immediate time behind bars for her role in a home invasion in which two firearms were stolen.

Kallista Mutten, 39, was sentenced to 12 months in prison for breaking and entering with magistrate Geoffrey Hiatt allowing her to spend this in the community under an intensive corrections order.

The robbery was allegedly carried out with her fiance Justin Stein and took place at an elderly man's Mount Wilson home in the NSW Blue Mountains in August 2021 where antiques and other items were stolen along with the two firearms.

The sentence was handed down at Campbelltown Local Court on Tuesday after Mutten pleaded guilty last month.

Mr Hiatt found she was a willing participant and that there had been a degree of planning involved in the robbery.

Charlise's body was found in a barrel dumped near the Colo River, northwest of Sydney, after a five-day search in January this year.

Stein, 31, has been charged with the girl's murder, which allegedly took place on his family's multimillion-dollar Blue Mountains property days before she was reported missing.

Mutten has not been implicated in the alleged murder.

This is not the first time she has been before the courts.

In 2017 at Lismore Local Court, she was jailed for three years and four months after her car plunged into the Tweed River, killing her friend who was sitting in the passenger seat. Mutten had ice in her system at the time of the accident.

She was granted parole in 2019.

On Tuesday, lawyer Bet Turgut told the court her client had suffered amidst "very tragic circumstances" but had seen some success through drug rehab.

"Your Honour, these are very tragic circumstances and Ms Mutten is attempting to put her life back on track. She acknowledges that drugs have been a major issue in her life," she said.

Under the intensive corrections order, Mutten is required to complete her rehabilitation program, remain under the supervision of corrections officers, and abstain from taking any illicit drugs.

Mr Hiatt stressed that breaking any of these conditions could see the 37-year old once more behind bars.

Stein has also been charged with several firearms offences and aggravated break and enter in company. He remains before the courts.
