Ramazan Acar is taken to court last year. Acar asked Ms D'Argent: ''Do you trust me? I wouldn't take her away from you like you took her from me.'' Acar put his daughter into the car. He picked up a long, ornate knife from the passenger seat and put it on the dashboard. He sped off erratically. Ten minutes later, when Acar failed to return, Ms D'Argent phoned him and asked where they were, beginning a torturous night of phone calls in which she begged for her daughter to be returned. At first, Acar told Ms D'Argent he and the girl had stopped at McDonald's and she'd be home soon. She wasn't.

Two-year-old girl Yazmina Acar's body was found dumped in Greenvale in November 2010. There were another two phone calls from Ms D'Argent to Acar at about 7pm. ''How does it feel not to have your child when I didn't have mine for three months,'' he asked her first. Later, he demanded she go to the police station and withdraw her intervention order. She refused. He replied: ''Well, I can't do you any favours'' and hung up. Fifteen minutes later, Ms D'Argent phoned Acar back. Yazmina Acar was stabbed more than once. Acar: ''Payback's a bitch. How does it feel?''

Ms D'Argent: ''Please Ramzy, bring her back. I just want my daughter back.'' Acar: ''Guess what baby, you're not getting her back. I loved you Rachelle, I loved you. Look what you've made me do. Now I just have to decide whether to go 120 [km/h] head on with another car and kill the both of us or take the knife and just put it through her throat.'' Ms D'Argent continued to plead for Yazmina's return and to work things through. ''It's too late, it's too late,'' he said. At 7.23pm, Acar updated his Facebook status to read: ''Bout 2 kill ma kid'' before he sent Ms D'Argent two text messages - ''I Loved You'' and ''It's ova I did it.'' Eleven minutes later, Acar again changed his Facebook status. ''Pay bk u slut''.

Within the hour, Ms D'Argent was with police when she phoned Acar again. He told her that he was ''going to kill her''. ''It's too late, I'm going to do it, I'm going to do it. Do you have any last words for her?'' Yazmina then got on the phone and told her mother: ''I love you''. Ms D'Argent replied: ''I love you too''. Acar then hung up. At 8.47pm came a confession. ''I've killed her,'' Acar said on the phone. ''She's just lying there next to me … It doesn't matter any more. All I need to know is should I dump the body somewhere and how much time do you think I am going to get for this? I killed her, man, I killed her. I killed her to get back at you. I don't care. Even if I go behind bars, I know that you are suffering.''

Two hours later, Acar sent another SMS to Ms D'Argent. ''I h8t you,'' he said, adding 20 minutes later: ''She's in heaven I feel lyk shit.'' Another Facebook status update came at about 11.20pm. ''I lv u mimi,'' Acar posted. Police arrested Acar about 10 minutes later. He told them he had stabbed Yazmina more than once. Pathologists would later conclude that Yazmina's death had been prolonged and painful because Acar had missed her vital organs. He confessed that he was embarrassed about the size of his murder weapon compared to his daughter's size, so hid the 30cm knife. Acar led police to his daughter, dumped in vacant land in a new housing estate in Greenvale. The knife was discarded in Campbellfield. Acar pleaded guilty in the Melbourne Magistrates Court yesterday to one count of murder. Magistrate Peter Reardon remanded him to appear in the Supreme Court later this month.

The on-and-off relationship between Acar and Ms D'Argent began when they were teenagers. There were several instances of domestic violence and threats of death and injury. When Acar showed up again at Ms D'Argent's flat on the day he killed Yazmina, it was another breach of an intervention order. She later told police she was tired of his violence and wanted to have control over her life and her daughter's. Ms D'Argent had moved closer to her childhood home after trying to live with Acar's family in Meadow Heights. At first, Acar resisted this new arrangement and tried to speak to his ex-fiance every weekend, turning up at her house and frustrated. Sometimes he would harass her while he was ''fried'' on drugs. Ms D'Argent reported every breach until she changed her phone number and he stopped contacting her. Later Acar resumed contact with Ms D'Argent through her mother. He was about to be locked up for driving offences, he said, and wanted to see ''Mimi'' before he went to jail. She agreed to meet him at Fountain Gate shopping centre and was shocked that he appeared to have changed. She said he appeared loving, bought their daughter things and was carrying Yazmina on his shoulders.

Acar asked if he could soon have Yazmina stay overnight with him. Again, Ms D'Argent explained, he appeared to be a ''whole different'' person - he sent text messages every hour about what she ate, how she reacted to seeing his family after a long absence. ''I have been asked why I stayed with him and one reason is that I was bloody scared, but also, the smile on my little girl's face when she saw her dad come home from work was priceless,'' Ms D'Argent said. Acar has been in custody since his arrest last November and, just before his police interview, asked Constable Mark Franco whether his case would be in the news. Loading ''My face and all, like Hudson?'' he asked, in an apparent reference to CBD gunman Christopher Hudson. ''F…, c…s will kill me in jail for this.''

Being in court yesterday for he ex-fiance's guilty plea meant ''the world'' for Ms D'Argent. Asked outside what she would say to her daughter, she said: ''Mummy's always going to be there for you.''
