Jessica hacked off her own mother’s head and paraded it down the street. Now prison insiders reveal her sickening new ‘hobby’ behind bars

She is considered one of Australia’s most dangerous women in prison. A ticking time bomb, ready to explode.

Serving 21 years and seven months for manslaughter, Jessica Camilleri decapitated her own mother Rita, 57, before carrying her severed head outside and dropping it on the footpath in July 2019.

While her traumatised family hoped the deeply disturbed woman would get the help she needed behind bars, insiders say Camilleri, now 30, is terrorising her prison wing and authorities don’t know what to do.

‘She has become an ongoing problem,’ a prison insider tells Daily Mail Australia.

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

‘There has already been time added to her sentence for attacks involving extreme hair pulling.

‘She has scalped people with her bare hands and anything can set her off.’

Camilleri was a troubled child. After being relentlessly bullied, she became obsessed with horror movies and making hoax calls threatening to decapitate the unsuspecting strangers who answered.

Friends, family and neighbours were all worried about her escalating behaviour, even warning her mother Rita it was only a matter of time before she killed someone.

‘Not my Jessica,’ Rita reportedly replied. ‘She wouldn’t hurt a fly.’

Two weeks after that chilling conversation, Jessica stabbed Rita more than 100 times.

Multiple knives were used and four of them broke during the frenzied attack.

Police found Camilleri covered in blood alongside her mother’s head. She asked officers if they could reattach it.

The rest of Rita’s body was found on the kitchen floor in their St Clair home, alongside her eyeballs and the tip of her nose.

A trial heard the then-27-year-old was in a fit of rage and was impaired by multiple mental disorders at the time.

Her sister, Kristy Torrisi, fought back tears as she told a court of the anxiety, pain, depression and anger she feels after her mother was taken by the ‘selfish hands’ of her own sister.

‘She was killed and butchered like she was nothing,’ Ms Torrisi told a sentencing hearing at the NSW Supreme Court.

Other family members said they hoped Camilleri would receive the help she needed behind bars.

But just two years into her sentence, she violently attacked two prison guards, ripping the hair from their heads.

The first assault happened during a search for sharps in August 2021, when Camilleri moved ‘hastily’ towards her cell door, slipped through the opening and was ordered to get back inside.

As the prison guard turned away, Camilleri seized her opportunity, ripping her hair out.

Camilleri later told police, she didn’t like the guard, ‘so I just wanted to give them a little bit of the taste of their own medicine’.

The second incident, in October 2021, occurred when Camilleri was in the prison yard and refused to put her hands through a hatch to be handcuffed.
