The events of 31 July 2010
4Early in the morning of Saturday 31 July 2010, the offender was working as a street prostitute in Kings Cross. The deceased approached her from his motor vehicle, and it was agreed between them that they would travel to a secluded part of Rushcutters Bay, where she would perform oral sex upon him for the sum of $70. They travelled to that nearby suburb, and the offender commenced to perform that act. Whilst she was doing so, the deceased as part of his obtaining sexual gratification, said some things about sexual assault of children. The offender reacted adversely to what the deceased said, but did not bring the arrangement to an end or seek to leave his car. To the contrary, it was agreed between the two of them that they would return to the flat of the offender in Macleay Street Potts Point, where she would perform a further sexual act upon the deceased in return for the sum of $150.
5They arrived there very early in the morning. The two of them were alone in a room together. The offender complied with a request from the deceased that she dress herself in particular clothes. The deceased had brought a laptop computer with him, and he connected to an interactive site on the internet whereby one can watch so-called "models" performing sexual acts in real time in return for money. The offender was in a position to see what was being shown on the computer screen, and she saw that one of the people depicted appeared to the offender to be an 11 or 12 year old girl. That further disturbed the offender.
6Thereafter, the offender performed oral sex on the deceased again. Whilst she was doing so, the deceased made reference to having had sex with her when she was a child. He additionally said something about having placed his penis in the mouth of the younger sister of the offender when she was a little girl and whilst she was asleep.
7Those things were said by the deceased in order to heighten his arousal from what the offender was doing. In fact, they were fantasies, because in truth he had never met the offender or her sister before that night.
8Tragically, those enunciated sexual fantasies of Mr Potter were to lead almost immediately to his violent death.
9Unbeknown to the deceased, the offender had been a victim of the crime of child sexual assault for many years. Those offences were committed against her by her stepfather, when she was between the ages of 8 and 15 years. They included many and varied acts of sexual intercourse, and, on at least one occasion, her stepfather saw fit to invite a friend of his to have sex with his stepdaughter whilst he watched. As a defence mechanism, the offender would adopt the strategy of psychologically dealing with these repeated crimes by "blanking out" during them; in other words, going into some sort of dissociative state. Furthermore, the stepfather would threaten the offender that, if she told anyone about what he was doing to her, she would be taken from the family, and he would be free to prey upon the little sisters of the offender (in fact her stepsisters). That threat was one of the reasons why the offender did not reveal what was being done to her whilst she was a child.
10A month or so before her encounter with the deceased, the offender had been sexually assaulted whilst she was working as a prostitute. The way in which that crime had been committed had some similarities with the way in which her stepfather had sexually assaulted her years before. At the time of the commission of that offence, the offender was powerfully reminded of what she had suffered in her childhood. In fact, it was only on the night that she encountered the deceased that the offender had returned to her work as a street prostitute.
11In short, completely unbeknown to the deceased, the offender had a special sensitivity with regard to child sexual assault, which had been exacerbated some weeks before, and she had an extreme sensitivity to the thought of sexual assault upon her little sister.
12Immediately upon the deceased referring to the little sister of the offender, she, to use her own words "sort of blanked out". In the opinion of a psychologist, which I accept, she entered into a dissociative state in which she was not fully aware of what she was doing. To use the language of the partial defence of provocation, she suffered a loss of self-control that I am satisfied was very profound. She picked up a piece of granite that was in the room for domestic purposes and struck the deceased to the head with it at least 30 times. Thereafter, she came to her senses to at least some degree, although she was still suffering from a loss of self-control. She did not do anything to assist the deceased who must have been by that stage very badly injured, if not close to death. Instead, for reasons that are not entirely clear to me, but probably included a desire to hide what she had done, some fear of retribution from the deceased, and an impulse to complete the violent assault that had commenced when she first lost self-control, the offender grabbed a knife and used it to stab the deceased to the throat three times. Two of the wounds were superficial, but one was over 12cm in depth and perforated the carotid artery of the deceased.
13At that stage the offender did not reveal what she had done. Indeed it was quite some time before she left the room and told her then-boyfriend, who had been sleeping in a nearby room, what had happened. During the intervening period, she made a primitive attempt to clean up and to hide her acts. When she did confess to her boyfriend, and he insisted that the police be called, she was not keen for that to happen, and expressed a desire not to go to gaol.
14Eventually police were called to the building and the offender was arrested. She chose to engage in an interview with police without the presence of a solicitor. During that interview she freely confessed her crime. The offender was charged with murder on that day, and has been in custody ever since.
