The murder offence
10A statement of facts, and a copy of the offender's Record of Interview with Police, were tendered by the Crown on sentence. Counsel for the offender informed me that the facts were agreed, and he made submissions to me regarding the findings I should make, based upon those facts, as to the circumstances of the offending.
11The facts of the murder offence may be summarised as follows.
12In October 2010, Karen Dawson ("Dawson") was a neighbour of the deceased. Mathew Aquilina ("Aquilina") is the adult son of Dawson and is the father of two young boys under the age of 3 years, and a step-father of a third boy under the age of 3 years. Those three boys stayed with Dawson for a period of a few weeks in October 2010.
13Deborah Grant ("Grant") was, in October 2010, the de-facto partner of Aquilina. She resided with him, and her six children, in Casino.
14Kristine Weston ("Weston") was, at the same time, the offender's de-facto partner and resided with him in Casino, in premises next to those of Aquilina and Grant. It was in these circumstances that the offender became acquainted with Aquilina.
15At the time of his death, the deceased resided alone in a caravan on a block of land at Red Range, a small village east of the township of Glen Innes, in northern New South Wales. The deceased was a bachelor, but had strong family connections in and around the Glen Innes area through, in particular, a nephew and a brother. He operated a small fruit and vegetable business from a street cart in Glen Innes in order to supplement his income. He was well known in the local area, was an avid cycling enthusiast, and being unlicensed, used a bicycle as his main mode of transportation.
16Dawson was an openly homosexual single mother who, with her 12 year old son Brandon, lived on a property at Red Range, the boundary of which adjoined that of the deceased. As a consequence, Dawson and the deceased became close friends. They often socialised together, and drank heavily in each other's presence. Due to the fact that the deceased did not have a driver's licence, Dawson would sometimes be observed driving with the deceased in her car in and around the local area.
17On 28 October 2010, Dawson drove the deceased to the "Jackadgery" Caravan Park located on the Gwydir Highway, approximately 120 kilometres east of Glen Innes. The deceased intended to stay the night at the caravan park, and then cycle across the Gibraltar Range back towards Glen Innes the following morning. Dawson arranged to collect the deceased the next day from a location known as "Ranger's Hut" which was about 70 kilometres east of Glen Innes. That evening, whilst at the caravan park, the deceased made a number of telephone calls to friends, informing them of his intentions to "ride the summit" the next day.
18At the time of being taken to the caravan park the deceased had in his possession an "Apollo" brand road bike, a black backpack and a bicycle helmet. The owner of the caravan park told police that at the time the deceased paid for his accommodation, he was observed to have a substantial amount of money in his possession, amounting to at least $1,000.00.
19On the morning of 29 October 2010 the deceased had coffee at the kiosk at the caravan park, purchased sweets for the ride, and left the caravan park at around 8:30am. At approximately 11:30am, he reached Ranger's Hut where he made a number of telephone calls to friends, indicating that he had arrived. A recipient of one of those calls told police that during the conversation with the deceased she heard a female voice in the background, at which time the deceased said that he had to leave because his "lift" had just arrived. The deceased was identified by a number of witnesses as having cycled along the Gwydir Highway that day. He was also identified as being at a public telephone box at Ranger's Hut.
20On the same morning Dawson had driven to Casino to see Aquilina. Aquilina then approached the offender asking him to travel with him to Red Range. Aquilina told the offender that Dawson was having troubles with her neighbour (the deceased) and that he (Aquilina) was proposing to go over there and "sort it out". The offender initially expressed some concerns about going, referring to the fact that he had only recently been released from gaol. He nevertheless agreed to go. The offender saw his role, at that point, as one of "back up" in the event that the deceased was to "get the better" of either Aquilina or Dawson.
21Dawson then drove Aquilina and the offender to her property at Red Range, stopping en route in Glen Innes to purchase a quantity of alcohol. During the journey, Dawson spoke of the difficulties she had been having with the deceased.
22After arriving at Red Range, Dawson left Aquilina and the offender at her property in an area known as The Old Butter Factory which housed an open shed. Dawson then drove to the top of the Gibraltar Range and collected the deceased, before returning to Red Range. Whilst Aquilina and the offender were at Red Range awaiting the arrival of Dawson and the deceased, Aquilina gave the offender a carving knife.
23The deceased and Dawson returned to Dawson's premises at Red Range. When they arrived, the deceased went to the area where the offender and Aquilina were waiting, at which time the offender approached him and they greeted each other. Simultaneously, Aquilina approached the deceased from behind and struck him to the back of the head with an iron bar, causing a laceration to his head. The deceased, who had been stunned by the blow, was assisted by the offender who proceeded to explain to the deceased why he had been struck.
24The deceased was thereafter questioned by Aquilina and Dawson, in the offender's presence, concerning his behaviour towards Dawson. He repeatedly denied the allegations which were put to him. At some point, the offender and Aquilina walked away, at which time Aquilina told the offender he was intending to kill the deceased. The offender replied:
"What? ... Dude, don't need to do that shit, talk to the bloke and try and get him to just stay on his property".
25Aquilina and the offender then returned. The deceased was then assaulted by Dawson and Aquilina in the presence of the offender. Dawson and Aquilina told the deceased that he could not leave, as they wanted to "sort everything out". The deceased walked past the offender, who was seated at the time. The offender got up and told the deceased to remain and "sort things out".
26At one point during the assault by Dawson and Aquilina, the deceased fell over and hit his head on a table, following which he hit the ground. During the fall, the deceased's glasses were broken and he sustained a cut across the nose which drew blood. When the deceased was on the ground, he was further assaulted with the offender watching. It must have been apparent to the offender at this point that he was unlikely to be required to perform any "back up" role as he had originally thought. I am satisfied that the offender was in a position to stop the violence perpetrated on the deceased, but did not do so.
27When the deceased was lying on the ground, Aquilina located a thick piece of rope that was nearby. He used it to fashion a noose which he placed around the neck of the deceased who was still lying on the ground. Aquilina commenced pulling on the rope and continued to do so for 15 to 20 minutes before handing the rope to the offender. Aquilina then grabbed the rope back from the offender, telling the offender that he was not pulling it tightly enough. Aquilina proceeded to pull the rope until such time as the deceased was blue in the face, and obviously dead.
28I am satisfied that the offender was aware that the deceased was going to be killed when Aquilina was pulling on the rope. I am also satisfied that the offender held onto the rope for some short period and pulled on it. However, I am satisfied that the physical act of choking the deceased was that of Aquilina.
29The body of the deceased was then loaded into the rear of Dawson's vehicle by herself, Aquilina and the offender, with the aid of a wheel barrow. The deceased's bike was placed on top of him. The area where the violence had occurred was then cleaned with bleach and hosed off.
30In the company of the offender and Aquilina, Dawson then drove the vehicle, containing the body of the deceased, to an isolated location known as Sandy Hill, located approximately 27 kilometres east of the township of Tenterfield. The body of the deceased was disposed of near a dirt fire trail at that location, and covered with sticks and leaves. All three persons then left the area.
31On 31 October 2010, Dawson, the offender and Aquilina returned to Sandy Hill There, the offender and Aquilina dragged the body of the deceased through a fence line, and rolled it down a steep slope until it hit a fallen tree, where they used sticks and branches to cover it. They then returned to the car and left the area with Dawson, in her vehicle.
32On Monday 15 November 2010, the deceased's brother attended the Glen Innes Police Station and reported the deceased's disappearance to the police. A police investigation was then commenced, and evidence was obtained detailing events leading up to what were the last public sightings of the deceased on 29 October 2010. The police investigation included the use of warrants authorising the interception of telephone services, as well as the use of listening devices at the premises occupied by the offender and Aquilina.
33The use of the listening devices, in particular, provided the investigating police with evidence linking Dawson, Aquilina and the offender to the death of the deceased. Other evidence obtained by the police established that between late October and early November 2010, bank accounts of the deceased were accessed, and the contents used to purchase a variety of items at locations in Northern New South Wales. The police investigation in this respect revealed that the transactions were conducted by the offender, in the company of other persons.
34The offender was arrested on 5 January 2011 at premises in Grafton, New South Wales. He participated in a electronically recorded interview, which has been tendered before me on sentence, in which he made various admissions relating to the deceased's death.
35The body of the deceased was located on 1 January 2011 down an embankment at Sandy Hill. His decomposed remains were still clothed in his bike riding apparel. A length of rope was tied around his neck and had wrapped around his torso, which had been crudely covered by sticks and branches, and left exposed.
36A post mortem was conducted by Professor Tim Lyons, Forensic Pathologist. The ultimate opinion of Professor Lyons was that the noose around the deceased's neck gave rise to neck compression and asphyxia, causing his death. He said that when pressure is applied to the neck area, there are three common mechanisms which can be associated with resultant death, namely:
(a)restriction of the airway;
(b)obstruction of the blood supply;
(c)the application of pressure to nerves of the neck.
37Professor Lyons described the noose as being 40 centimetres in circumference, and found that it had been wrapped twice around the deceased's body. Leaving aside detected defects in the soft tissues of the clavicle, Professor Lyons also observed that there was a defect in the deceased's body consistent with his genitalia being absent. However, he was not able to come to a definitive conclusion as to whether the deceased's genitals had been removed by a person, or whether they had been removed as a consequence of animal predation or heavy maggot infestation.
38It is evident from his statements to the police when interviewed that the offender, from the outset, had some concerns about what might occur if were to go to Red Range. That, in my view, is the only reasonable construction which can be placed upon his reference, when Aquilina asked him to go with him, to the fact that he had only recently been released from gaol. However, I am satisfied that at least at that point, the offender saw his role as being that of a back up for others, rather than the instigator of any violence.
39It was submitted on behalf of the offender that I should find that his involvement commenced at or about the time he was given the rope by Aquilina. However, such a finding would, ignore what had occurred up to that point. Although I am not satisfied that the offender knew that Aquilina was going to assault the deceased with the iron bar upon his arrival, he was necessarily aware, from the point at which that assault occurred (particularly in circumstances where he had been given a knife by Aquilina) of the likelihood of violence being perpetrated on the deceased. Contrary to the submission made on behalf of the offender, I do not regard the fact that the offender chose to come to the deceased's aid at that time as affecting, in any way, the offender's awareness of the likelihood of violence.
40More significantly, as a result of his subsequent conversation with Aquilina, the offender became directly aware of Aquilina's intention to kill the deceased. Whilst the offender's attempt to dissuade Aquilina from carrying out his stated intention was laudable, the fact is that thereafter, and with direct knowledge of Aquilina's intention to kill the deceased, the offender remained present, observing gratuitous violence being perpetrated upon the deceased who was largely defenceless. The offender conceded to police that he had been in a position to stop that violence, but did not do so. Not only did he not stop the violence, he prevented the deceased from leaving the area.
41Counsel for the offender submitted that because a period of time had elapsed following the offender's conversation with Aquilina when no violence was perpetrated on the deceased, the offender was entitled to assume that Aquilina had decided not to take his stated intentions any further. That may be so. However, the submission overlooks the fact that when the violence resumed, the offender observed it, took no steps to stop it, and assisted by preventing the deceased from leaving. He had no reason to think at that point that Aquilina had been dissuaded in any way from his stated intentions.
42Moreover, having been present when Aquilina fashioned the noose, the offender must have been acutely aware, at that point, that Aquilina's previously stated intentions were about to be carried out. There is no suggestion that the offender tried to dissuade Aquilina at that point. Indeed on the evidence, the offender stood by, watching Aquilina choke the deceased with the rope, in circumstances where he was ready, willing and able to assist as and when required.
43The offender himself told police that Aquilina had given him the rope, and that that he (the offender) had then held on to it before Aquilina grabbed the rope from him, telling him that he was 'not holdin' it tight enough'. I am satisfied that the offender pulled on the rope when he was holding it, although it is evident from Aquilina's statement to him that he was doing so with limited force. I am satisfied that in terms of the pulling of the rope, the offender's role was minimal compared with that of Aquilina. However, the offender remained nearby, willing and able to assist.
44The offending had a number of aggravating features. The use of a ligature has been treated as a form of weapon (as to which see Versluys v R [2008] NSWCCA 76) and accordingly this is an aggravating feature pursuant to s21A(2)(c) of the Sentencing Act. Further, the offence was committed in company (s21A(2)(e) of the Sentencing Act).
45The offender has a lengthy history of previous convictions dating back to 1987, recorded in New South Wales, Victoria, Queensland and Western Australia. Whilst those convictions are not on the scale of the present offending, the offender's criminal history is nevertheless an aggravating factor under s. 21A(2)(d) of the Sentencing Act.
46Further, the offender's criminal history establishes that only 9 days prior to the commission of the murder offence, he had received the benefit of a suspended sentence following an appearance at the Southport Magistrate's Court on a charge of possessing a dangerous drug. Accordingly, the offender was on conditional liberty at the time of the murder offence which is an aggravating factor under s21A(2)(j) of the Sentencing Act.
47The offender's participation, on two separate occasions, in the treatment of the deceased's body at Sandy Hill following his death is also an aggravating factor (see for example Knight v R [2006] NSWCCA 292; R v Yeo [2003] NSWSC 315).
48Having regard to the fact that Professor Lyons was not able to come to a definitive conclusion about the matter, I am not satisfied the deceased's body had been mutilated by the removal of his genitalia. Even if I were in a position to be satisfied of that fact, there is no evidence at all which would link that mutilation to any conduct on the part of the offender. In any event, the general principle that treatment of the body of the deceased (of a kind in which the offender was involved) is capable of amounting to an aggravating factor has been extended to cases where such treatment did not involve any form of mutilation: R v Goundar [2010] NSWSC 1170; R v Dong [2010] NSWSC 1242.
49In my view, taking into account all of these factors, the offending falls at the mid range of objective seriousness.
