Background Facts and Evidence
6The following summary is taken from the evidence led by the Crown at the trial. To the extent that there was any dispute concerning the material, I will identify it and make my assessment having regard to the jury's verdict. Before I make a finding adverse to the offender, I must be satisfied of that matter beyond reasonable doubt (R v Isaacs (1997) 41 NSWLR 374). Any findings in his favour may be proved on the balance of probabilities (R v Pilley (1991) 56 A Crim R 202).
7At the time of his death, Hoang Tang, and Ms Toni McCaw were in a de facto relationship. They had three children together. One of their children had died in his infancy. Tuesday, 6 July 2010, was the sixth anniversary of that child's death.
8The deceased, Ms McCaw and the offender were all receiving treatment for drug addiction. The offender lived in Macquarie Fields and had known the deceased and Ms McCaw for some years. He was friendly with both of them.
9On the morning of 6 July 2010, the deceased, Ms McCaw and the offender met while taking public transport to different methadone clinics.
10The offender went to Liverpool and received his dose of methadone. The deceased travelled to a pharmacy in Parramatta for his dose. Ms McCaw received her methadone from a pharmacy in Fairfield. She then purchased a six pack of bourbon and coke from a nearby bottle shop. She consumed some of the six pack at a park. She then travelled to Guildford and met the deceased at a pharmacy where they obtained prescriptions for Serepax and Valium. They travelled to a shopping centre in Fairfield where the deceased sold their prescriptions to another drug user. They both took some Serepax and Valium. They went to a liquor store where Ms McCaw bought some more pre-mixed bourbon and the deceased stole a bottle of bourbon from the liquor shop. By this time it was the middle of the afternoon.
11Ms McCaw and the deceased went back to her home at Eucalyptus Drive, Macquarie Fields. They arrived late in the afternoon. They performed a Buddhist prayer ceremony for their deceased son. They talked about him. They drank some more bourbon and went upstairs.
12Sometime after 7pm, the deceased began making comments to Ms McCaw about an ex-boyfriend. She became worried and asked him to leave. The deceased said to her "We're both going to die tonight". At 7.28pm she dialled 000. The deceased took the mobile telephone from Ms McCaw and she hit him on the arm with a spanner. She threatened to hit him again.
13At this point the offender telephoned the deceased on his mobile phone. He answered it. Ms McCaw yelled out "I'm scared, come over". The deceased ended the call. Ms McCaw told him to leave as he was too drunk to stay.
14Shortly afterwards, the offender knocked on the door of Ms McCaw's home. According to Ms McCaw, the offender "calmed the situation down and took the spanner off me". The offender told the deceased to come and stay at his place. They both left. They were seen leaving by a neighbour in a jocular mood.
15At about 8pm on 6 July 2010 the police attended Ms McCaw's home to respond to the 000 call. One of the officers asked her if everything was alright and she said that it was and that she must have accidentally called 000.
16As I have stated, the offender also lived in Macquarie Fields. His house was near a high school. At the trial a number of witnesses gave evidence of an altercation between two men just outside his house later that evening, although the times varied. The witnesses were clearly referring to the offender and the deceased. Two witnesses described the altercation as having occurred around 11.30pm. One described a fight in which one of them was dragging and punching the other and yelling "Where's my fucking money, where's my fucking money. I want my money now". She heard the victim "moaning". She saw the aggressor collect an "Otto bin" and attempt to put the deceased inside. Her friend also described the encounter in similar terms although her description of the altercation suggested more of a struggle than a one way beating.
17Another witness, a Mr Matthew Gleeson, claimed that between 9.30 and 10.00pm, or possibly later, he drove into the street and witnessed a confrontation in which the offender was on the defensive and the deceased was in the ascendancy. I accept that Mr Gleeson witnessed an altercation between the offender and the deceased. However, for the reasons set out below, I am satisfied that the jury rejected so much of his evidence as suggested that the offender was defending himself.
18As I will explain, these descriptions appear to be the culmination of a confrontation between the offender and the deceased that had started inside the offender's house and spilled outside.
19At approximately 1.30am on 7 July 2010, Ms McCaw was woken by the offender. He told her that he had "done something, something bad happened". The offender said that "Wang's gone for a walk so I am going to find him". He told her to get some clothes. Ms McCaw collected some clothes for the deceased and accompanied the offender to his house.
20They walked to the offender's house through the grounds of the high school. Unknown to Ms McCaw she passed nearby the deceased who was lying in a creek that ran through the school grounds. While they were walking the offender told her that the deceased had robbed him. When they arrived at the offender's house, she saw the deceased's clothes. She recalls the offender being angry and repeating that the deceased had robbed him and that he wanted his phone and money back. She recalled the offender saying that around $300.00 was missing and that he "wants his fucking money". Ms McCaw looked for the money and phone and found the latter in a pot plant on top of the toilet. She observed blood towards the top of the staircase in the offender's home. She began to cry. She recalled the offender stating "[t]hat is where I first hit him".
21Ms MsCaw assured the offender that his items were still in the house and suggested they look for the deceased. They left and the offender took her to the creek, approximately 250 metres from his house. The deceased was naked, lying in the creek on his stomach. She touched him. He felt very cold but she could still hear him breathing.
22Ms McCaw and the offender dressed the deceased. She could see that the deceased had a cut above his eyebrow, a lot of blood on his face and grazes on his feet. Ms McCaw asked the offender why the deceased was naked. The offender said he was "looking for his money, to make sure it wasn't between his butt cheeks".
23They both dragged the deceased up an embankment. Ms McCaw called an ambulance. The offender ran to a nearby ambulance station. The transcript of the 000 call reveals her panic and distress. She did not tell the operator of the offender's involvement.
24The police arrived at the scene prior to the ambulance. The offender was at the scene with a torch and led them to the deceased. Both he and Ms McCaw told them that the deceased had gone for a walk and that he and Ms McCaw went looking for him.
25The deceased was taken to Liverpool Hospital. He had facial and skull fractures with brain injuries. He was suffering from hypothermia and had a number of cuts, abrasions and bruises. There were red marks on his throat. He was unconscious. He never regained consciousness. He died on 8 July 2010.
26Around 6.40am on 7 July 2010 police attended Ms McCaw's home and spoke to her and the offender. Both Ms McCaw and the offender again told the police that they had gone looking for the deceased at the creek and did not know how he sustained the injuries. The offender denied that he had consumed any alcohol or drugs on the previous day other than his prescription medication.
27The offender was taken to Macquarie Fields police station. He participated in two video recorded interviews. In the first interview he admitted attacking the deceased but claimed it occurred after the deceased had touched the offender on the leg and on his genitals. He said he had hit the deceased in the lounge room of the offender's home. The offender claimed that he had been the victim of sexual abuse as a child. The offender was unable to say how many times he hit the deceased, whether he used any weapon, or what part of his body he had hit. He said there was an "... explosion of anger". He also alleged that the deceased had stolen money from him that evening. He said he carried his body to the creek and left it there because he believed he had killed the deceased. He said he only realised that the deceased was still alive when he returned with Ms McCaw.
28At the conclusion of this interview, the offender told them that he lied about the deceased touching him and said it was "not right for him to be known that way". The offender agreed to participate in a further interview ("the second interview").
29In the second interview, the offender admitted that he had lied when he told the police that the deceased had touched him in a sexual way. He stated that after they returned to his place both he and the deceased went to sleep. He said he woke to discover the deceased had taken his money and his mobile telephone. He confronted the deceased and locked the door. He said he punched the deceased when he tried to force his way out the door. He said the deceased fell back onto the staircase. The offender stated that he believed he had killed him and so he carried him to the creek. The offender denied transporting him in the Otto bin and reiterated that he had only hit the deceased once.
30Towards the end of his interview, the offender became increasingly unbalanced and abusive. He was then returned to the charge room area and was provided with a meal which he threw on the floor. The offender was then taken to the dock area where he proceeded to urinate on the floor, defecate and then smear his faeces on himself and the dock.
31A forensic examination of the offender's home revealed a significant amount of blood on the staircase. The blood pattern was consistent with the deceased having been dragged down the staircase. There was blood on the wall adjacent to the staircase. A wooden handle was found in the kitchen. It had blood stains. DNA analysis revealed that it was the deceased's blood. There was an Otto bin near the house with blood stains on the outside and the wheels were muddy. There were track marks in the grass nearby.
32The post-mortem examination revealed that the cause of death was multiple blunt force injuries, primarily to the head and neck. The deceased suffered a number of injuries and fractures to his skull. The forensic pathologist, Dr Matthew Orde, stated that they were caused by two and possibly more separate blows to his skull. Dr Orde also described the deceased as having "multiple surface injuries to the neck, primarily to the front and right side of the neck; the injuries to the left front aspect of the neck have a linear component", and raised the "possibility" of the application of a ligature (i.e. something around the neck). In his evidence he suggested it could have been a belt, but accepted that those marks could also have been the result of the deceased being transported in an Otto bin with the weight of the head outside the bin.
33The deceased also had lots of minor abrasions and bruises all over his body. Dr Orde stated that in isolation some were fairly minor, but considered together they were widespread and quite extensive. He described many of these injuries as non-specific, but said some could have been caused by an implement such as the wooden handle. He also accepted that a number of the injuries to the body were consistent with the deceased having been dragged, including the bruising to the arm pit. Dr Orde accepted that it was conceivable that, if the deceased was dragged, this could have caused some of the bruising.
34The offender gave evidence at his trial. Contrary to his statement to the police on the morning of 7 July 2010 the offender stated that he had consumed a significant amount of benzodiazepine drugs on 6 July 2010 which affected his memory. He recalled coming back to his house with the deceased after he intervened between the deceased and Ms McCaw on the evening of 6 July 2010. He recalled going to sleep and waking to find his money and telephone missing. He stated that he confronted the deceased at the top of the stairs. He recalled there was a fight but claimed that he could not recall anything further. This was said to be due to the effect of the drugs he consumed. In cross examination the Crown Prosecutor suggested that he was feigning a lack of memory.
