Woman, 25, Charged With Mother’s ‘Horrific’ Murder Appears In Court

A woman accused of murdering her mother after an alleged argument has appeared in court.

Jessica Camilleri, 25, faced Parramatta Bail Court on Sunday afternoon charged with the “horrific” murder of her mother Rita in their home in the western Sydney suburb of St Clair, near Penrith, the previous night.

She appeared via video link and did not apply for bail, with her lawyer telling the court she had significant health issues.

The accused also told Magistrate Michael Price she had a number of conditions, including border autism, bipolar disorder and anxiety.

She said in court that she couldn’t move her fingers properly after “the incident” and hadn’t been able to wash herself properly in the shower to get all the blood off.

Magistrate Price ordered the accused be assessed in hospital before her next court appearance.

The body of the 57-year-old woman was found suffering "multiple injuries" inside the St Clair home around 11.40pm on Saturday, NSW Police said.

The woman was allegedly decapitated, with her head found several doors down from the home.

"This is up there with one of the most significant, most horrific scenes police have had to face," Nepean Police Area Commander, Detective Superintendent Brett McFadden said. First responders are receiving counselling after witnessing the scene.

"We understand at this stage that a number of knives were used during the course of the incident," McFadden said.

A four-year-old boy at the home -- said to be the dead woman's grandson, but not the son of the accused -- suffered a minor head injury, and was taken to hospital for treatment. It is believed the boy witnessed the incident.

Officers had been called to the scene after reports of an argument between the women, which police said turned "violent".

Police said a knife was seized from the home for testing, with a number of crime scenes established inside and outside the residence.

The incident is being investigated as a suspected domestic violence murder.
