'I walked down to the front of the house and he just started punching my face,' Ms Silva told veteran journalist Michael Usher about that night three years ago. 'All he was saying was, 'all of yous deserve to die... all of yous deserve to die'' Ms Silva said he then held her brother by the throat so she ran inside to retrieve a knife with which to defend herself and her brother. Upon returning to the scene, she could hear Mr Polkinghorne screaming, 'I'm going to kill yous.' It was then that she stabbed him five times in the shoulder, chest and back. 'It was just to kind of scare him, I didn't think I was going to use it,' she said. 'But he looked up and went to grab me again and drag me down... that's when I stabbed him.'

On visiting Mr Polkinghorne in Queensland, Ms Silva said she was nervous and was seeking forgiveness . Last month she walked free from court, free to tell of the four years of horror and warning other women not to make the same mistakes.

'He was a better bloke than he ended up being,' he told 60 Minutes. 'He was always there to help someone.'

Mr Polkinghorne told Ms Silva he is still working on forgiveness during the emotional reunion. ‘No anger, no hatred,' he told her. 'That was a very tense meeting (with the father), very nervous, both sides very nervous,' Michael Usher told Daily Mail Australia. Jessica Silva admits she was living in fear and violence and she told no one. 'When her mum saw the red marks on her heck she said "it was just a rash", it's brutal and as bad a domestic violence as you could hear' Grace and Avalino Silva (Jessica’s parents). He revealed to Michael Usher that the ordeal had so destroyed Jessica that 'I looked into my daughter's eyes and I didn't recognise her' 'She tells it in a ridiculously raw, emotional but extremely clear way, she deeply regrets that she ever had to end up in that situation and that it came to that' Michael Usher said of the Jessica Silva interview . 'His family, his father, has had to deal with a lot of anger and hatred. 'He doesn't understand why she had to kill his son, it's only the start of a process, there is no neat ending at all.' 'She wants forgiveness in the family she finds it hard, it was a case of kill or be killed, she had no doubt that night that she would die. 'It was chilling when she described those moments.' During the course of her trial, Ms Silva repeatedly wept in court as the jury heard a series of abusive phone calls and texts sent by Mr Polkinghorne before his death. Another message, from the day he was stabbed, read: 'I hope your mother gets poisoned by the flowers that you give her and you get gang raped.' Michael Usher revealed that Jessica's motivation to tell her story to 60 Minutes was to 'send a warning to others, she did everything wrong, that she should have left at the very first sign of violence .

Before his death, during the phone conversation between Silva and her brother Miguel, she was heard saying: 'He reckons he's gonna come and kill me, right now’. When Miguel tells her to call the cops, an increasingly distressed Silva replies: 'Why do you think I don't tell them so he can bash me up all the f***ing time. I'm sick of it ... and I don't know what to f***ing do any more.' 'Is there anyone we can f***ing contact ... to get him killed or something?' she asks, later adding: 'Don't worry I'll f***ing stab him myself'.
