On January 16, 2015, a visibly shaken Leila Alavi hung up the phone after taking a call from her estranged husband.
Prosecutors say the 26-year-old turned to a colleague and told him: "He said he is going to kill me and all of us. Probably he is watching too many movies."
By morning, she was dead.
In the carpark below the western Sydney hairdressing salon where she worked, Mokhtar Hosseiniamraei stabbed his wife 56 times with a pair of scissors he had stolen from a nearby supermarket.
"That moment. Like a bomb. It exploded. I didn't realise what I was doing for a moment," he would later tell a forensic psychiatrist.
But in the hours after the stabbing on January 17, 2015, when police asked him through an interpreter why he had killed Ms Alavi, Hosseiniamraei was frank: "Because we were married, and ... she broke the contract. I could not tolerate it.
"And I could not forget it."
Documents tendered in the NSW Supreme Court on Thursday tell of the devastating loss suffered by Ms Alavi's loved ones, and the broken logic with which her killer tried to explain what he had done.
"Where did you hit her with scissors on her body?" police asked Hosseiniamraei.
"In her heart and in her neck. Because she did not obey the rule of marriage," the killer replied.
"When we marry we have a commitment, moral commitment towards one another. In this country this means nothing."
He has since pleaded guilty to murdering Ms Alavi.
Hosseiniamraei, a refugee who fled Iran because of religious persecution, met his bride in Turkey and travelled with her to Australia in 2010.
By late 2014 the relationship had broken down and Hosseiniamraei was abusing drugs daily.
A psychiatrist who interviewed the 34-year-old noted he had been using heroin and ice almost every day around that time, and was smoking up to 28 joints of cannabis a week.
Ms Alavi sought a restraining order on October 2014, but documents before the court indicate the couple continued to see one another regularly.
Even after their separation, Ms Alavi continued to visit Hosseiniamraei to cook and clean for him, according to the offender's sister.
Now the dead woman's relatives have questioned why more was not done to keep her safe.
In a victim impact statement tendered in court on Thursday, Ms Alavi's sister Marjan Lotfi wrote that the grief of losing her was "almost unbearable".
"I don't want other women to suffer the same tragedy. I don't want other family members to go through what I and my family have gone through," she wrote.
"I keep thinking: why didn't someone help her? Why didn't she receive the protection she needed?"
Another sister, Mitra Alavi, said she and Leila had left Iran to escape violence. She said she had worried for years about her little sister's relationship with Hosseiniamraei.
"I saw that she was abused both physically and psychologically by him. I believe this man was cruel and dangerous," she wrote.
Justice Robert Allan Hulme will sentence Hosseiniamraei next Thursday.
