Sebastian Carlier-Sosa to be released in six weeks after indecently assaulting 13-year-old girl in Westfield centre

A 13-year-old girl sexually assaulted with her mum at Westfield Marion is still too scared to go shopping, a court has heard.

A man who “opportunistically” indecently assaulted a girl shopping with her mother and siblings will be released from prison in roughly six weeks – but a cracked Macca’s window will keep him under supervision.

Last week, Sebastian Frano Wilhelm Carlier-Sosa, 24, appeared in the District Court to be sentenced by Judge Paul Muscat over the incident that left the victim “afraid to go to the shops”.

In a victim impact statement read to the court, the 13-year-old girl, now 14, said she still worried about returning to Westfield Marion, where the assault occurred.

“I do get sad when my friends ask me to go shopping with them, but I usually say no as I’m too scared to go without a parent, even though my mum was with me when it happened,” the victim wrote.

Carlier-Sosa was arrested in November last year after he, in the company of two friends, walked up behind a family pushing a trolley through the Westfield shopping centre.

The girl was wearing her school uniform at the time, when Carlier-Sosa, of no fixed address, walked passed her and touched her hip, before grabbing her buttocks.

The girl told her mother immediately after, who informed security and police, who attended and arrested Carlier-Sosa while still in the Marion centre.

During sentencing, Judge Muscat said Carlier-Sosa told police he had injected himself with methamphetamines earlier on the day of the offending.

The court heard Carlier-Sosa had previous convictions for assaulting a 24-year-old woman outside a post office when he slapped her on the buttocks.

The court heard he had been admitted to hospital five times between January 2023 and his arrest in November for drug-induced psychosis relation to his use of meth – which also led to a charge of property damage.

“The drug-induced psychosis is complicated by your ongoing use of drugs and alcohol, homelessness, low intellectual functioning, ADHD, and anti-social personality traits,” Judge Muscat said.

Prosecution urged the court to consider implementing conditions to keep Carlier-Sosa under supervision pending his release – an appropriate penalty for the pending charge of property damage, to which he pleaded guilty to after a short adjournment.

Judge Muscat sentenced Carlier-Sosa to six months and 24 days for the indecent assault of the young girl, and a 12-month supervised good behaviour bond for breaking a window in the Tea Tree Plaza McDonalds.

That sentence means Carlier-Sosa will be released from custody on June 23, 2024 when the sentence concludes.

Judge Muscat urged Carlier-Sosa to stop taking methamphetamines to reduce his risk of being a danger to the community.
