Mr McArthur - factual findings
16There was no agreement with respect to the facts for sentencing purposes in the case of Mr McArthur. It was necessary in those circumstances for evidence to be led on matters of significant dispute. Those matters were the identification of the particular implement used by Mr McArthur that caused the death of the deceased and the related issue of whether or not Mr McArthur came armed with it, as well as whether or not Mr McArthur intended to kill the deceased or merely to cause him really serious injury.
17Dr Matthew Orde is a forensic pathologist who gave evidence by video link from Canada. Dr Orde is the medical specialist who carried out the autopsy upon the deceased on the day following his death. He prepared a report dated 23 May 2012 that was tendered without objection.
18Dr Orde gave the following evidence concerning the question of what implement may have caused the fatal injury to the deceased:
"Q. You have described the edges of the wound, in the last sentence of the second paragraph under 'torso', 'the inferior edge was somewhat shallow and the top edge was slightly undercut'. Firstly, might you explain that and also indicate what that could mean, what conclusion it is possible to draw as to a knife with a sharp edge and the other side of the knife being the blunt side?
A. I looked at this injury carefully, looking for signs which may point to a particular weapon. And there are difficulties in attempting to do that because we know that various weapons can produce various pattern injuries. There is not always a correlation.
In this case, I noted the one end was somewhat squared and the other end was what more pointed which, to me, suggests that the weapon, probably a knife or similar, would have had one cutting edge and probably one relatively noncutting edge. The shelving is probably, for the purpose of this, neither here nor there. It just reflects the underlying trajectory of the wound path into the tissues."
19Dr Orde was also asked about the grazing type wounds to the deceased's leg. He said the following:
"A. [Photographs] 115 and 116, so we can see there in those photographs, towards the back of the lower part of the leg, the lower part of the calf, there are multiple fairly parallel scratches or shallow cuts to the leg. The spacing of these cuts suggests to me that these cuts would have been made by a serrated edge, as may be seen on a knife..."
20Dr Orde was cross-examined on this issue as follows:
"Q. Now the wound to the chest, could that be caused by something like a screwdriver being forced into the chest?
A. It is always difficult to make certain conclusive comments about the object which caused an injury like a stab wound. The shape of the wound to the skin and to the deep structures depends upon many variables, not least the speed at which the object was thrust into the person's body but also the relative angle and movement between the weapon and the victim. Having said that, I think the injury to the left upper part of the chest was characteristically that of a cutting weapon such as a knife. I certainly wouldn't favour a screwdriver. I think the width that went into the skin would be too long to be accounted for by such a mechanism, so I simply favour a cutting object for that injury. As to the injuries to the right lower leg, again I would favour a cutting object with a longer, broader cutting edge, rather than something like a screwdriver.
Q. You use the term 'like a knife' some object that at least has one edge that is somehow sharpened is what you think would cause those two injuries, is that right? It needs one sharpened edge?
A. There may be two sharpened edges, I can't be certain?
Q. But at least one?
A. At least one sharp edge. I would favour something like a knife and looking at the deeper aspect of the stab wound to the chest, the injury gradually tapered to a smaller width as it went deeper, so I would favour a knife which had a pointed, tapered end. But again, it is difficult to be certain as to that sort of aspect of these injuries.
Q. The difficulty is, it is much easier to make a conclusion about the possibility of a particular injury being caused, if you are provided with a weapon to use for comparison to the injury, is that correct?
A. Yes, the best thing we can do is, if we are shown a weapon, obviously a pathologist will be able to say yea or nay. But it is difficult for me to describe the likely shape of any weapon, just looking at the injuries."
21In re-examination, Dr Orde was not particularly enthusiastic about the suggestion that the fatal injury to the deceased could have been caused by a screwdriver, as the following evidence reveals:
"Q. The suggestion that it could have been a screwdriver that caused the stab wound to the chest, what differences, if any, would you expect to see from what you have seen in this if a screwdriver had been used?
A. If a screwdriver - again, it all depends upon the nature of the screwdriver, the width of the blade, the length of the blade, its sharpness and all the rest of it. So again, many variables come into play. But assuming we are talking about a typical, fairly small diameter screwdriver with a small shaft, then one would expect a smaller injury to the skin. That need not always be the case, of course, because the screwdriver might move relative to the body and then extending the wound. But in this case, if you look at photograph 41 you can, I think, appreciate there that the edges of the injury to the skin are quite clearly cut along the whole length of this wound. So I don't think you could account for that by something like a screwdriver, which has a relatively blunt edge. This means an injury caused by a sharper edged object such as a knife, rather than a screwdriver."
22Chelsea James gave evidence. She confirmed the terms of her conversation with Mr Robertson, referred to earlier at [13], and adhered to what she said when challenged about it by Mr Stratton SC for Mr Robertson. She was also asked about Mr McArthur, as the following passage reveals:
"Q. The other matter I wanted to ask you about is what Mr Robertson said, if anything, about Darren McArthur. Do you understand, I want to ask you about an aspect of that?
A. Um.
Q. I will ask you specifically. You said some things in your statement about the interactions between Mr Robertson and Mr McArthur, correct?
A. Yes.
Q. What I want to ask you is did he say anything about how Mr McArthur came into this job or became involved or why?
A. From what Darren had told me is that he asked Darren McArthur to help him with it. That's he asked him to go with him."
23Linda Sharon Monsuere gave evidence that she knew Mr McArthur, and that about three or four days before 5 December 2011 he told her that he had a job to do in Sydney. She said that on an occasion in late November 2011, Mr McArthur was at her home and told her that "a boy had died on him". Ms Monsuere said that she had known Mr McArthur to carry a knife in the waist of his pants.
24A couple of days after the death of the deceased, Mr McArthur again visited Ms Monsuere. She gave evidence about what was said as follows:
"Q. Did he say anything about the death of this young man?
A. Yes.
Q. What did he say?
A. That the kid died on him, that he wasn't supposed to die.
Q. The following week, did he come around to your house and did he talk about money?
A. Yes.
Q. What did he say?
A. He was wanting the money that he was owed for doing the job."
25It would appear that following this conversation some phone calls were made to Mr Robertson from Ms Monsuere's mobile phone.
26Mr McArthur gave evidence. He maintained that what had happened was a mistake. He said: "I was just told to ask for the owner and to punch him in the mouth." He said that he was asked to do the job by someone called Macca, and that he would be paid in drugs. He was using ice at the time of the offence and had been regularly using illicit drugs. As he said, "I was a bad junkie at the time." Mr McArthur said this in evidence:
"Q. How you came to go down to Minchinbury in Sydney and entered this factory? What led you to do that?
A. I was just asked to give someone a hand.
Q. Who asked you?
A. Darren asked me.
Q. And what did he say?
A. He just said, 'Give us a hand. We are just going down to Sydney to talk to someone'.
Q. Was there anything other than talking to someone suggested?
A. No, I just thought it was just to bash someone or something."
27Mr McArthur was asked about what happened when he entered the premises. He said this:
"A. I couldn't see anybody in there. I didn't think there is anybody there but the roller door was up. I went outside, I was on the driveway a bit and I went back and I heard something. When I walked in there was someone down the back of the factory. I started walking towards the person. I said, 'are you the owner?' They said, 'yeah'. I tripped over something just before I got to the person. I tripped and landed on them. The person pushed me back like that and I just freaked out. Because I landed on him, the way I walked towards him he must have thought something was up and he started lunging at me and I spun out. I didn't know what was going on. I was just going to hit somebody. So as I am falling over, I am trying to get back out, I was thinking of running out. Trying to get to my feet, I tripped over something, I grabbed something and I was just lunging at him. He was coming towards me, I had hold of him and he had hold of me. He went flying over, he went over my head, sort of thing, as I tripped over. He hit the ground. His legs was up this end of me. I slashed at his leg. He didn't move. I just shit myself and then I left, walked out and just ran down the road."
28Mr McArthur denied that he entered the premises armed with anything, including a knife. He said that he stabbed the deceased with something that came to hand on the floor of the premises as he was struggling with the deceased. His evidence was as follows:
"Q. You say you took hold of something. Do you know what it was you took hold of?
A. Um, it was like a saw or something like that. I am not sure, it was just like sharp. It was a piece of metal about [30cm] long."
29Mr McArthur admitted that he took hold of the item in order to stab the deceased. However he was unable with any particularity to describe the implement. He said that he threw it from the car as he was driven away by Mr Robertson. He agreed that he slashed at the deceased's legs with the implement. He described it when cross-examined as "a long piece of metal".
