A mother who stabbed and killed her husband before dismembering his body to be dumped in rubbish bins could be released as early as next year.

Nirmeen Noufl, 56, appeared before the Supreme Court for sentencing on Friday — weeks after a sensational backflip in court and admitting to killing her husband Mamdouh at their southwest Sydney home in May 2023.

She had pleaded not guilty to murdering Mamdouh September last year and was expected to challenge the allegations in a trial in August only to instead plead guilty to a downgraded charge of manslaughter.

Nirmeen returned to court on Friday to hear Justice Peter Hammill’s judgement on the case, which he said had a number of “unusual” details.

Court documents seen by 7NEWS.com.au revealed Nirmeen stabbed and killed Mamdouh sometime on May 3 as an argument between the couple spiralled and he became violent, chasing her around the house and striking her.

Nirmeen would dismember Mamdouh’s body over the following days and pack him into rubbish bags to be disposed in rubbish bins across Sydney before cleaning the floors of her home with bleach.

Cleaning the crime scene was just part of Nirmeen’s cover-up, which included her continuing to post to social media from Mamdouh’s account and texting from his phone.

But the ruse fell apart in July, with her husband’s family formally filing a missing person’s report months after he was killed and leading to her arrest.

Dismemberment tore family’s ‘souls apart’

While the Crown ultimately agreed on the facts, it argued the dismemberment of Mamdouh’s body meant the evidence could only rely upon Nirmeen’s account.

The agreed upon facts state that in May 2023, Mamdouh told Nirmeen he planned to leave her to marry another woman in his home country of Egypt.

He had been in a romantic relationship with the other woman while on a trip to the country between August and November 2022.

When Nirmeen asked him to get a divorce before marrying his lover, Mamdouh declined, according to the facts.

The argument took place days afterward, which Nirmeen said was ended with her stabbing him once to the left side of his chest.

The Crown also argued the disposal of his body in the days after the accident should be a factor in her receiving a greater sentence.

Hamill said the dismemberment and disposal was the most “disturbing feature” of Nirmeen’s case, adding it was as “thorough as it was brutal”.

The detail was also a sticking point for his Egyptian family, a number of which penned victim impact statements to the court before sentencing.

His nephew said the “way his life was brutally ended, and the horrific cruelty that followed, has town our souls apart”.

“We have no grave to visit, no soul to touch and no place to lay flowers or recite prayers over his body,” he said.

“Knowing that his remains are lost, denied the sacred dignity of a proper burial, is a silent, unending torment that will haunt us for the rest of our days.”

Arranged marriage the start of violent relationship

Nirmeen was 10 years younger than Mamdouh when they first met at their marriage ceremony in November 1991.

“Basically my dad sold me to him,” Nirmeen said in court documents.

The couple had eight children together, a number of which wrote affidavits supporting their mother’s claim that Mamdouh was controlling and abusive to Nirmeen and the couple’s daughters.

Justice Hamill noted that police had been called to the family’s home a number of times, but no formal reports were made.

Those recounts became a crucially relevant part of Hamill’s sentence for Nirmeen, saying it “placed the killing in a proper context”.

“The traumatising impact of being exposed to violence within the family home is well understood by the criminal courts,” Hamill said.

Nirmeen and her siblings noted their father was physically and sexually abusive of them as a child. Nirmeen was especially singled out being the eldest child.

She wept as Hamill recounted her life of abuse.

Hamill found that Nirmeen’s history of mental health, abuse as a child and at the hands of Mamdouh were factors in her sentencing.

He added that Nirmeen had since shown remorse for killing Mamdouh, adding she felt she had “let her children down” and that the unique circumstances surrounding the case meant there was little relevant cases for him to reference as guideline’s for Nirmeen’s jail term.

Hamill ultimately sentenced Nirmeen to a total of six years and three months behind bars with a non-parole period of three years stretching back to her arrest in 2024, meaning she will be first eligible for release in October 2027.
