History of the Proceedings
2 Each of the defendants is entitled to the benefit of pleading guilty to the charges preferred against them. The matter was first listed, in this Court, in relation to each defendant, on 12 April 2002, on which occasion a trial date was fixed for 22 July 2002. It was then stood over for arraignment on 7 June 2002, on which occasion SJB alone was arraigned and entered a plea of not guilty. The arraignment concerning McLean was stood over to 25 June 2002. On that occasion he offered a plea of not guilty of murder, but guilty of manslaughter; as well as a plea of guilty to a charge of larceny of a motor vehicle. The former plea was not accepted but the latter was.
3 When the matter of SJB was listed before me on 16 July, she entered a plea of guilty to murder. As noted hereafter, it was on the following day that she was formally interviewed, and provided to Police her account of the relevant events. Counsel appearing for McLean indicated this day that he would also offer a plea of guilty to murder. It may be noted that his intention to do so was announced and carried into effect on 17 July, that is, before he knew precisely what it was that SJB would say to Police, (although he understood that she did intend to assist them). On that occasion he was reindicted and his plea of guilty to murder was recorded.
4 In relation to the offence involving Mr Tonkiss' motor vehicle, he was given leave to withdraw the earlier plea of guilty to larceny, and pleaded instead to take and drive a conveyance without consent. That plea was accepted by the Crown.
5 Thereafter the matter was listed for sentence on 30 September, 1 October and 22 to 24 October, being adjourned on 1 October to allow for psychiatric assessment of SJB.
6 In a number of respects there are significant matters in dispute between the defendants concerning the killing of Stephen Tonkiss, which occurred at about 12.35 pm on Tuesday 24 July 2001. What is not in dispute is that he died following an entirely unprovoked and senseless attack on his person, in the course of which he received multiple knife wounds.
7 It is also not in issue that this attack occurred shortly after he had driven SJB, at her request, to the premises at Seaforth, where McLean was living. While there, McLean and SJB armed themselves with a knife each, in McLean's case, a silver serrated cutlery knife, and in SJB's case, a Zangler-Icel brand Knife. McLean collected an additional weapon in the form of a relatively large metal nutcracker. Thus armed, they joined Mr Tonkiss in his Mitsubishi Lancer Sedan, and asked that he drive towards Seaforth shopping centre where McLean was ostensibly to be dropped off.
8 When the vehicle reached Ellery Parade, and while it was still in motion, SJB, who was sitting in the rear seat, leaned over and stabbed Mr Tonkiss in the face. Thereafter the defendants repeatedly stabbed him, inflicting a large number of wounds, mainly to his upper body. While this was occurring, the car which he was driving rolled to a halt, sustaining minor damage when it struck the rear of a parked vehicle.
9 A brief struggle ensued between Mr Tonkiss and McLean, before the former managed to escape from the vehicle. He ran some distance to the nature strip outside number 9 Ellery Parade, Seaforth, where he collapsed. While there he received further knife wounds, which I find were inflicted by each of the defendants, and he was punched and kicked.
10 Eventually the two defendants ceased their attack upon Mr Tonkiss, and lifted his body over a low brick wall into the front yard of the adjoining premises.
11 At that point, after taking his wallet, they drove from the scene in his motor vehicle, stopping at St Ives to purchase petrol. They then drove on to Nelson Bay, where they remained until later that night, before driving on to Newcastle.
12 At about 5.35 am on the morning of 25 July, the victim's car was seen and stopped by Police at Newcastle. The defendants were each arrested and taken to Newcastle Police Station. The knife used by SJB was found inside the glove box of the vehicle. The knife used by McLean had earlier been found on the nature strip outside 9 Ellery Parade. Each knife was bloodstained. DNA recovered from the knives was of the same profile as the DNA of Stephen Tonkiss.
13 While at the Police Station SJB, on legal advice, declined to be interviewed. McLean participated in an electronically recorded interview (ERISP), in which he admittedly told several lies, including an assertion that Mr Tonkiss had stopped the vehicle while they were going for a drive and had held a knife to him, while feeling SJB's leg. It was his account that he feared that SJB would be raped, and that the deceased was accidentally stabbed when he struggled with him for the knife. He confirmed this version in a later interview the same day.
14 Ambulance officers who had attended the scene at 12.43 pm found the victim to be in cardiac arrest, and not breathing. His life was pronounced extinct shortly afterwards at Manly Hospital.
15 The post mortem examination conducted by Dr Cala on 25 July 2001, revealed that Mr Tonkiss had received 13 separate stab wounds, the most serious of which were the wounds which he numbered 3 and 4. They were respectively a 25 mm stab wound in the left upper chest, which penetrated the deceased's lung; and a horizontally aligned stab wound in the left chest entering the chest cavity, carrying on through the upper pericardium and through the pulmonary artery, creating a 15 mm wound deficit in the wall of the ascending aorta. The remaining stab wounds which were noted comprised a wound on the left cheek (wound 1), a wound to the right side of the lower neck, penetrating the subcutaneous tissue for a depth of 50 mm (wound 2), a wound in the left anterior shoulder passing into the subcutaneous tissue (wound 5), a wound below the left shoulder on the lateral aspect of the left upper arm passing into the musculature (wound 6), a fish shaped wound on the lateral aspect of the left upper arm which passed into the biceps muscle (wound 7), a further wound on the lateral aspect of the left upper arm which also passed into the left biceps muscle (wound 8), a superficial wound on the lateral aspect of the left upper arm, passing into the underlying superficial subcutaneous tissue (wound 9), a curved wound in the left posterior shoulder region passing into the deltoid musculature (wound 10), a superficial wound in the left upper outer chest (wound 11), a wound in the left mid-outer back region passing into subcutaneous tissue (wound 12) and a wound to the back of the head, passing into subcutaneous tissue (wound 13).
16 A number of other lesser injuries were discovered including incised or stab wounds respectively to the left outer chest, left upper arm, left upper chest, left ear region, right index finger, right middle finger, and left parieto-occipital region. Additionally, abrasions or bruises were seen over the 4 - 5 metacarpels of the dorsum of the left hand, above and below the right knee, left occipital region, left parieto-occipital region, and right back. Some of these additional injuries appear to have been of a defensive type. Others are consistent with blows or kicks to the head and body of the victim.
17 Dr Cala expressed the view that the deceased died as a result of multiple stab wounds, the wounds to the chest numbered 3 and 4 alone having been fatal. He also expressed the opinion that wounds 1, 2, 3, 7 and 9 were most likely inflicted by a person seated behind the deceased, while wounds 4 and 8 were most probably inflicted by a front seat passenger. This observation is of limited value, however, since it assumes that the victim was still in the car when the wounds were occasioned, a circumstance which appears not necessarily to have been the case. Of greater relevance was his observation that of the wounds described, only wounds 3 and 4 were such as to have caused the deceased to collapse on the nature strip.
18 What I have said so far does not explain why it was that the defendants attacked and killed Mr Tonkiss. It is necessary to explore the evidence in this regard, in a little more detail, since it is relevant for an assessment of the objective criminality of each offender. It is also relevant for the question which arises as to their state of mind.
19 There is some common ground in relation to the events leading up to 24 July, as emerged from the evidence given by each defendant, which was supplemented to some degree by the statements of friends and associates, and by call charge records. While each of the defendants gave evidence, the interviews which each had with Police were admissible only against whoever was the maker. Additionally, conversations which SJB had with fellow students were only admitted in relation to her.
20 Before turning to the evidence in more detail, it is to be noted that, at the time of the killing, SJB was aged 15 years, having been born on 3 December 1985. McLean was aged just over 18 years, having been born on 20 April 1983, and Stephen Tonkiss was aged 20 years, having been born on 30 December 1980.
21 McLean and SJB, it is clear, were involved in a close sexual relationship, which had been in existence for about 3 to 4 months before the events of 24 July. SJB had known Stephen Tonkiss for a longer period, and on her account, she had engaged in sexual activity with him on one occasion well before the present events.
22 On Wednesday 18 July 2001 there were a number of telephone calls made by Stephen Tonkiss to SJB, timed at 5.59 pm, 6.24 pm and 6.59 pm, which culminated in an arrangement for them to meet. It appears from the statement of Lorraine Tonkiss that he made those calls in response to a call which had been placed earlier by SJB, in which she had asked whether he was home, and had left her name.
23 It was SJB's evidence that she received these calls at the home of her friend Gaby. Arising from them, Mr Tonkiss drove her, and Gaby, to the lookout near the Quarantine Station at Manly. Some alcohol in the form of Passion Pop was consumed. At one stage Gaby made herself scarce, and in her absence SJB and Mr Tonkiss kissed in his car. She was somewhat vague in her evidence, as to whether this encounter progressed into further sexual activity, remarking either that she could not remember, or was not sure, because of the alcohol she had consumed.
24 At 8.50 and 8.51 pm, call charge records show that reverse charge calls were made from Mr Tonkiss' mobile phone to the landline of the premises where McLean lived. Both calls were very brief, and it seems that these were made by SJB.
25 It was SJB's evidence that Mr Tonkiss drove her back to Gaby's place, from where her father picked her up, later that night.
26 On Thursday 19 July, it is common ground that SJB missed a planned meeting with McLean. However, by chance they met up on a bus which SJB had caught with her friend Gaby, on their way to the city to purchase some concert tickets. After some uncertainty as to whether she would continue with her journey to the city, SJB eventually left the bus with McLean.
27 They returned to his home, where SJB confessed to him that she had "cheated" on him. I am satisfied that, in addition to saying that she had "kissed or pashed" with Mr Tonkiss, she said enough to indicate to McLean that she had been drunk, and may have gone somewhat further than kissing. She denied however, telling McLean that Mr Tonkiss had raped her, and she accepted that whatever had happened between them was consensual.
28 The accounts which each of the defendants gave, in relation to the discussions which followed upon this revelation, as well as in relation to the events on 24 July, differ substantially, and it is necessary to deal with their versions separately.
29 SJB said, in her evidence, that McLean was very angry when informed that she had cheated on him. She said that he required her to hold a knife to his throat, to prove that she was "true" to him and loved him. He also said words to the effect that "You have to stab Stephen because you cheated on me", "you can't live in this world with him here", and "I don't want him alive in this world because I don't trust you in this world with him". There were several variants in her evidence as to what was said, but this seems to have been the substance of the response which she attributed to McLean.
30 She said that McLean showed her how to stab Mr Tonkiss by stabbing a box of Arnott's biscuits. He then asked her to do the same, which she did.
31 On her account the exchanges were very emotional, with McLean being angry and she being distressed.
32 It would seem from the evidence that she stayed at McLean's house until the following Monday, although that is not entirely clear.
33 Whether SJB remained at McLean's house until the Monday or went home earlier, it is certain that they saw each other on a regular basis over the succeeding days. It is also common ground that a number of attempts were made by them to get in contact with Mr Tonkiss over this period.
34 To this end, on Friday 20 July, telephone calls were placed by SJB to the home of Stephen Tonkiss, which were taken by his brother and mother. In the course of them SJB claimed to be a girl called "Cindy" and indicated that she needed to meet Mr Tonkiss to recover a jumper which she had left in his car. She asked for his mobile number but this was not supplied. She said that McLean gave her instructions on what she was to say to Mr Tonkiss.
35 On Sunday 22 July 2001, at 3.21 pm, a phone call was made from Mr Tonkiss' mobile phone to SJB's mobile phone. This call would appear to have followed several calls which had been made by SJB from a payphone, and which were taken by Mr Tonkiss' sister, in the course of which SJB indicated that she wished to speak to Mr Tonkiss urgently, again referring to her need to recover a jacket which had been left in his car. She repeated her request for his mobile number, but this was again refused. On the third occasion the caller identified herself by the first name of SJB, and left her mobile number so that Mr Tonkiss could phone her. Several further phone calls were made this afternoon to Mr Tonkiss' home, only one of which, again being a call from SJB, was answered.
36 On Monday 23 July, at 11.41 am, a call was made from the landline service at McLean's home to the service at Mr Tonkiss' home, lasting some 22 seconds. This call was taken by the victim's brother, and was from a female, who made a somewhat bizarre mention of being "Stephen's daughter".
37 Tuesday 24 July was the day on which SJB returned to Cromer High School, at the conclusion of the school holidays. During that morning, SJB said that she spoke to some of her friends regarding the holidays, and in particular in relation to the problem in which she had found herself with McLean and Mr Tonkiss. They included SS and ND. She said that she informed SS that McLean had said she was to stab Mr Tonkiss in the head. Statements from these witnesses were tendered in relation to SJB, which confirmed that she had mentioned her problem, and, in the case of SS, that she had gone on to say that McLean had asked her to stab Mr Tonkiss. SS counselled SJB that she could not do this.
38 At 10.53 am, a reverse charge call was made from Mr Tonkiss' home to SJB's mobile phone, in which he asked her why she had been calling him. She enquired whether he wanted to meet up. At 11.18 am, SJB used the pay phone at the school to phone McLean at his home. This was a somewhat lengthy call lasting over 5 minutes. She informed McLean that Mr Tonkiss had phoned. He instructed her to arrange for Mr Tonkiss to meet her and drive to his place, to pick him up.
39 At 11.23 am, SJB used the school pay phone to speak to Mr Tonkiss, at his home. In this call she arranged to meet him. A further call was made by SJB from the pay phone at the school to McLean at 11.30 am. This was followed by another call at 12.04 pm from Mr Tonkiss, using his mobile phone, to SJB on her mobile phone, confirming the arrangements for a meeting.
40 She then left school and made her way home. SJB said that, having picked her up outside her home, she asked Mr Tonkiss to drive her to McLean's home, again using the excuse that she wanted to pick up a jumper. Leaving him in the car parked outside, she went to the door of McLean's bedroom, off the veranda. She left her school bag behind, and took one of the knives which he handed to her, concealing it in her pocket.
41 After joining Mr Tonkiss in his car, she said that they set off in the direction of the shops. At one point, she said, McLean turned around and looked at her. Taking this as her signal, she told Mr Tonkiss to stop or to slow down. She then stabbed him in the chin, setting off the series of blows which followed, in the course of which Mr Tonkiss fought unsuccessfully for his life.
42 She was somewhat uncertain, in her evidence, as she had been in her ERISP, as to the number of times she had stabbed Mr Tonkiss. She conceded however, having stabbed him three times, first to the chin at the commencement of the attack, secondly while he was struggling with McLean in the car, and thirdly on McLean's instructions while he was lying on the ground. In this regard she said that McLean had told her, both during the struggle, and while Mr Tonkiss was on the ground, to stab him.
43 It was accepted by her that their plan had been one whereby she and McLean were to meet up with Mr Tonkiss, and that he was to be stabbed. She rejected as untrue the version which McLean gave of meeting up with Mr Tonkiss for the sole purpose of talking to him about the alleged rape and cautioning him not to do it again. It is clear that she entered the car with McLean with the clear understanding that he was to be seriously harmed.
44 It is less clear whether she intended or expected, initially, that he would be killed, although at one point in her cross examination, she said that McLean had told her that he wanted Mr Tonkiss to drive to his home in order to kill him.
45 Her evidence as to her intention when she stabbed him on the ground, was contradictory. In cross examination the following exchange occurred (T 251 and 252):
"Q. It was quite obvious to you that, by the time he'd reached the footpath, he was dying, isn't that right?
A. Yes.
Q. Yet you stabbed him again, didn't you?
A. Yes.
Q. You did that knowing that it would help to bring about his death, didn't you?
A. Yes.
Q. You were spoken to by a number of people from the Department of Juvenile Justice at Yasmar, is that right?
A. Yes.
…
Q. You told those people that McLean said to you, this is whilst Stephen is lying on the footpath to 'make sure he's dead'. Remember telling that to those people?
A. Yes.
Q. Is that something McLean said to you on that occasion or is it something you're making up?
A. I'm not making it up and that's what he said.
