Charlise Mutten’s mother’s meth and sex session with her fiancé hours after her daughter’s alleged murder

The mother of murdered schoolgirl Charlise Mutten had sex and injected methamphetamine with the man accused of murdering her daughter, just hours after he allegedly killed her.

Kallista Mutten, 40, became emotional as she told a jury that her daughter had asked her earlier if she could “go with daddy” before he shot her and put her body in a barrel.

Ms Mutten took to the witness box to give evidence against her former partner Justin Stein in the NSW Supreme Court in Parramatta on Monday.

Stein, 33, is due to stand trial after pleading not guilty to murder but admitted disposing of the schoolgirl’s body.

He is accused of murdering his former fiancée’s daughter on a property owned by his parents before dumping her body, hidden in a plastic barrel, near the Colo River area.

The girl visited her mother during school holidays and spent her time in New South Wales, split between Stein’s family property at Mount Wilson, where she was allegedly shot and killed, and at a caravan park called Riviera Ski Gardens in Lower Portland for about an hour and a half. far.

Ms Mutten broke down in tears during her testimony on Monday when she told the court Charlise had asked if she could “go with Dad” on the day police allege she was killed.

The mother of murdered schoolgirl Charlise Mutten became emotional as she told the jury her daughter asked if she could “go with daddy” before he shot her and put her body in a barrel.

Kallista Mutten, 40, took to the witness box on Monday to give evidence against her former partner Justin Stein in the NSW Supreme Court.

The 40-year-old walked into court wearing a long-sleeved black shirt, navy skirt and black heels as she gave evidence against her former partner, her blonde hair resting on her shoulders.

“He told me he had to go back to the Blue Mountains, to Mount Wilson, to let this auctioneer in for his mother because she was selling antiques,” Ms Mutten said.

“Charlise had finished swimming in the pool and she said, ‘Can I go with Mom and Dad?’

She told the court she replied: “Yes, of course.”

Mr McKay alleges that Stein was the “last person” to see Charlise and that he had the opportunity to see her between 7:16 p.m. on January 11 and 10:06 a.m. on January 12.

The next day, the jury heard that Charlise woke up vomiting and was left at Mount Wilson, allegedly in the care of the auctioneer, while Stein went to pick up Ms. Mutten.

Ms Mutten told the court that Stein called her to explain the situation and was told the woman had “three children and she’s practically like a nurse, so Charlise was in good hands”.

Prosecutor Ken McKay SC told the court Stein sent Ms Mutten a text on the morning of January 12 which said “pack an overnight bag bub”.

“To be honest, I thought he was planning our escape… that was the surprise they gave me, so I wasn’t too sure,” Ms Mutten said.

She told the jury that after Stein picked her up from the caravan park, they drove to Sydney where they bought methylamphetamine and injected it at a nearby park and had sex.

The couple then returned to the caravan park, where Ms Mutten said they were going to be “intimate again”.

“He told me she (the auctioneer) was happy to look after her (Charlise) even during the night and that we had time to spend together,” Ms Mutten said.

“We were going to be intimate again and spend the night together but I was too worried about Charlise so I wanted to go back to the mountain.”

They returned to the Mount Wilson property and arrived at 8:44 p.m. and found no lights on in the house.

Ms Mutten told the jury she did not find it strange until Stein said it was strange.

She said she was “trying to be rational” about where Charlise was and assumed the auctioneer took her daughter because she wasn’t feeling well.

The jury heard the barrel containing Charlise’s body was found on January 18, 2022, after police attended the scene after looking at Stein’s phone.

Stein’s lawyers say it was Ms. Mutten who fatally shot her daughter on the evening of January 12, 2022.

Phone calls recorded while Stein was in jail were played to the jury earlier in the trial, where he was heard warning his mother that he couldn’t “tell her everything over the phone.”

Justin Stein, 33, is due to stand trial after pleading not guilty to murder but admitted disposing of the schoolgirl’s body.

Kallista Mutten told the jury after Stein picked her up from the caravan park and they drove to Sydney where they bought methylamphetamine and injected it at a nearby park and had sex.

The girl was visiting her mother during school breaks and spending time at Stein’s family property in Mount Wilson, where she was allegedly shot and killed.

In the first phone call, which took place on the morning of February 5, 2022, he told Annemie Stein that the police had approached him to ask about the location of the murder weapon and where Charlise had been killed.

“They don’t even know anything,” he said in the recording.

Annemie told her son “No, but she wasn’t killed at Mount Wilson”, to which Stein replied “I know”.

The mother continued: “But they pretended it was.”

“Alleged doesn’t mean shit, all it means is I’m going to beat the murder charge,” Stein responded.

Another call was played to the jury on February 10, 2022, during which Stein said Ms. Mutten was “going to be charged for everything.”

He doubled down that “it’s the truth”, telling his mother that the police had “nothing” and couldn’t “pin” him for the murder, but that he “saw” it happen.

The trial continues before Judge Helen Wilson.
