Sydney man allegedly murdered and ‘butchered’ by wife after she discovered affair with woman overseas

A Sydney woman is accused of murdering her husband and dismembering his body after discovering he had a secret lover overseas, it has been revealed.

Nirmeen Noufl, 53, is alleged to have killed her husband, Mamdouh Noufl, 62, to whom she had been married for more than 30 years and had eight children.

The motive behind the gruesome alleged murder is believed to be Mamdouh’s affair with a woman in Egypt, to whom he had been sending money, 7NEWS understands.

Investigators believe the tragedy may have unfolded over several months after Nirmeen allegedly discovered the affair.

Tensions began to mount, and during a heated argument at their home on Juno Pde in Greenacre, the confrontation turned deadly.

Mamdouh was reported missing by family friends in July last year after he had not been seen since May, and a public appeal was launched by NSW Police when he could not be located.

The Greenacre man’s disappearance was deemed suspicious by police, who then spent over a year investigating before arresting his wife.

Mamdouh’s death was brutal, macabre and bizarre, NSW Police Homicide Commander Detective Superintendent Danny Doherty said, adding that police had enough evidence to allege his wife murdered him.

“We will allege, also, that she butchered and dismembered his body, placed his body parts in plastic bags and then disposed of his remains in various rubbish bins in residential areas and industrial areas of southwest Sydney,” Doherty said on Saturday.

Nirmeen was arrested while staying as a patient at Banks House — an acute adult mental health inpatient unit at Bankstown Hospital on Thursday. The next day she was charged with domestic violence-related murder at Bankstown Police Station.

A crime scene was also established at the Noufl’s home of more than a decade, located on June Pde in Greenace on Friday.

Family friends thought Mamdouh was travelling overseas but could not reach him, prompting their concern, according to Doherty.

Nirmeen allegedly attempted to cover up the crime by spinning a web of lies and misinformation after disposing of the body.

“We will allege ... the accused had taken over Mamdouh’s phone and social media accounts purporting that he would still be alive,” Doherty said.

“That probably delayed some of the investigations and also was probably a ruse to disguise the fact that he had been killed.”

Mamdouh’s bank accounts were used after his disappearance until police began investigating.

Nirmeen would have allegedly received significant financial benefit from her husband’s death, Doherty said.

There was no record of previous interactions with police concerning domestic violence, he added.

The pair had eight children, who are adults, however, none of them are believed to have been involved.

She was formally refused bail in court on Friday and is due to next appear before Burwood Local Court on December 11.
