Personal circumstances of Bevan McKellar
38Bevan McKellar was born in 1983 and was aged 28 at the time of the offences.
39His criminal history commenced when he was aged 13. He has been dealt with for a variety of offences including receiving; break, enter and steal; entering inclosed lands; car theft; assault; assault occasioning actual bodily harm; malicious wounding; affray; contravention of an apprehended domestic violence order; intimidation; and larceny. There are multiple occurrences of some of those offences. He has been sentenced to full-time custody on quite a number of occasions.
40His past response to parole has been blemished by revocation of parole on three occasions (2004, 2006 and 2009). He has spent the vast majority of the past 13 years in gaol.
41Bevan McKellar was on bail in respect of a charge of assault occasioning actual bodily harm at the time of the commission of the present offences which is a serious aggravating factor. He received a 3 month prison term for that offence on 20 June 2012 and it was specified to take effect upon imposition. Accordingly, the period in which he has been in custody solely referable to the present offences is 3 months less than it otherwise would have been.
42Dr Olav Nielssen was engaged after the trial to prepare a report in respect of Bevan McKellar. In relation to his state of mind at the time of the offence he told Dr Nielssen, "I was intoxicated ... I had a few beers with the boys and I'm drunk ... next thing I know I'm sitting in here", meaning a prison cell.
43He told Dr Nielssen that he could remember little of his schooling. He could "read a little bit but it's not good". He could perform basic arithmetic. He was good at sports. He left school relatively early. His subsequent employment experience was limited.
44He began drinking alcohol when he was young and it had been a problem over the years. He told a nurse who wrote another report that I will mention shortly that, "I was on the grog from about age 11 and was pretty well drunk most of the time when I was not in custody". He gave up drinking alcohol upon his previous release from gaol (the records indicate this was probably in April 2010) and had not consumed any until the day of the offences. He began using cannabis at around age 12 or 13 and had smoked it most days of his adult life. He had also used methamphetamine, but only "from time to time".
45As to his family background, he told Dr Nielssen that he was the fifth of nine children, one of whom had passed away. His father died when he was young. His parents were from the Wangkumara tribal group from the far northwest of the State. He was born in Bourke and spent his early years there. The nurse's report includes that he had "a sad dysfunction[al] childhood" and that he reported "domestic violence and years of physical and emotional abuse from his father ... and his elder brothers".
46Bevan McKellar sustained a head injury in a high impact motor bike accident in June 2006. Reports by a mental health clinical nurse consultant with the Statewide Community & Court Liaison Service dated 13 January 2011 and by an occupational therapist/outreach worker with the South West Brain Injury Rehabilitation Service dated 17 February 2011 were tendered. They indicate that while frontal lobe damage was suspected, he was transferred from Royal Prince Alfred Hospital to Dubbo Hospital but then discharged. There was no appropriate follow up involvement of a rehabilitation service. Testing indicated moderate memory impairment. He required reminders about attending appointments. Instructions given at the beginning of half an hour of conversation were not recalled by the end.
47Another impairment assessed as consequent to the head injury was a difficulty in controlling his anger: "He stated he has found that if pushed his frustration level becomes too great and he 'hits out'; this has, he stated, been difficult to control since his injury". The author of the South West Brain Injury Rehabilitation Service report indicated that it would provide a variety of rehabilitation services to Mr McKellar. However, it was only 3 months later that he was arrested and held in custody for the present offences.
48Dr Nielssen discerned from his consultation with Bevan McKellar that there were signs of frontal lobe injury with significant memory impairment. He said, in part, "he appeared blank and confused, and was slow to respond to questions and his verbal responses were vague in content and simple in form". He noted that typical symptoms of frontal lobe injury involved impairment of emotional regulation, planning, social judgment and impulse control. There can also be increased susceptibility to the effects of alcohol.
49Dr Nielssen made the following formal psychiatric diagnoses: Traumatic brain injury and Substance use disorder.
50Dr Nielssen concluded his report as follows:
"Mr McKellar has a combination of disorders and a pattern of past behaviour that would predict further offending. He will require ongoing supervision and support after his release, to minimise the likelihood of resuming alcohol abuse and to help make up for the deficits in memory function and emotional regulation arising from his brain injury. However, it is not possible to predict Mr McKellar's individual circumstances, or the services that might be available when he falls due for release, and hence any estimate of future dangerousness can only be made in the most general terms."
51It was submitted that I should find that there was a causal connection between Bevan McKellar's mental condition arising from his brain injury and the commission of the offences. I accept that difficulties with impulse control and particularly with control of anger are consequences of that injury. But a countervailing feature might be that he was aware of the potential for excessive drinking to adversely affect his behaviour. He told Dr Nielssen that his problem with drinking was "the only reason I come to gaol". However, it must also be accepted that his ability to maintain a resolve to be abstinent was rendered more difficult because of his reduced impulse control.
52If there was a causal connection between Mr McKellar's mental condition and the commission of the offences it is indirect and somewhat tenuous. It is notable that he committed a number of offences of violence, likely influenced to a degree by intoxication, both before and after the accident in 2006.
