Woman who decapitated her mother in brutal attack has prison time reduced as judge makes ruling

A woman who is currently in prison for stabbing her mother more than 100 times could be out sooner than expected following a ruling from a judge.

Jessica Camilleri was jailed back in 2019 and sentenced to a minimum of 16 years for killing her mother in a brutal frenzied attack.

Camilleri stabbed her mother, Rita Camilleri, more than 100 times and severed her head, dumping it outside their family home in St Clair in western Sydney, Australia.

Despite being sentenced to the 16 years, she was found guilty of the lesser charge of manslaughter due to 'substantial' mental health issues.

While in prison, Camilleri, 37, has reportedly had multiple altercations with prison authorities that have resulted in more than 17 months added to her sentence.

Speaking to Daily Mail Australia, an insider said: “She has become an ongoing problem.

“She has to be monitored at all times because she will use any opportunity to cause harm.”

Most recently, she pleaded guilty to common assault which earned her an extra six months in prison on June 3.

However, following this, an appeal was launched against the sentence and Judge Graham Turnbull handed down his judgement on Wednesday (July 9).

The court was previously told that Camilleri struggled in custody more than other inmates due having disabilities and suffering from trauma.

Her lawyers requested the judge consider his client serve this additional six months concurrently, meaning served at the same time instead of being tacked onto the end.

The judge did state that it appeared that in all of the incidents involving Camilleri and altercations, none of them seemed premeditated but rather situational.

But he also said it was important to note that her conduct needed to be denounced.

While the appeal was initially formally refused, Judge Turnbull varied the sentence so part of it would be served concurrently with her earlier prison sentences.

This ultimately means that she will begin serving her sentence on August 4, 2032 instead of December 4, 2032, with her new release date brought forward four months to February 3, 2033.

Camilleri will be eligible to apply for release on July 19, 2031.
