Subjective features of the respondent AB
23 The respondent was 17 years of age at the time of the commission of the offence and 19 years at the time he was sentenced. His Honour had before him a number of reports including a report from Dr Jeremy O'Dea, a forensic psychiatrist, Dr Yolande Lucire, also a forensic psychiatrist, Mr Greg Fathers, a forensic psychologist, Mr Jeff Otto, Juvenile Justice officer and Miss Karen Clarke, a psychologist with the Violent Offender Program with the Department of Juvenile Justice.
24 AB's father has three children from a former relationship and his mother five children, all significantly older than AB and his sister. All members of the family, including AB are aboriginal (by descent from their maternal grandmother) although they do not identify themselves in this way. AB's father helped his mother raise her children, who resided with them and the new family. One of his half-brothers (DE), has undertaken an elder brother's responsibility for a younger sibling and attempted to help AB during his teenage years and has continued supportive contact with him since the offence. He gave evidence for the offender at the sentence hearing.
25 The relationship between AB's parents broke down permanently in mid 2001 after many short separations. The major reasons for this break-up was continuous domestic violence, accompanied by alcohol and other drug abuse. AB's mother is apparently in receipt of a disability pension due to injuries she suffered during her marriage.
26 AB was brought up in a very small rural community with a population of less than 100. During his formative years his father would take him with him when he went working in the bush, the two of them returning home for weekends before going out the following week. AB's father was a violent and in some respects disturbed individual. He was frequently violent towards AB's mother in the presence of the children. His father often used firearms when making demands. Sometimes violence was instigated by AB's mother, on one occasion attacking his father with a knife. There were not infrequent occasions of cruel violence towards animals, including one occasion when in the presence of the children (AB was then seven) the father shot the family dog for having taken a fowl, this despite the dog having sometime earlier saved some of the children from drowning.
27 AB and the other children were frequently subjected to physical and emotional violence at the hands of his father. AB started to resist his father from as young as ten years. When each of the children was around sixteen, their father required them to leave home, one of them at the point of a gun. Because of his mother's concerns about AB's drug consumption, he was sent to live with his uncle for six months at the age of ten. During this time there was a distinct improvement in his behaviour and he started responding positively at school.
28 AB left home at about the age of fourteen moving in with a cousin, with whom, and others, he drank and took drugs daily. His life was chaotic in almost every respect amounting to little more than finding enough alcohol and cannabis and, occasionally, amphetamines which he used until he "passed out." He did not care about his personal hygiene or eating regularly. His accommodation was somewhat casual. At the time of the offence, AB was mostly living with his girlfriend, then in her mid twenties and pregnant at the time with their daughter who at the time when AB was being sentenced was aged twenty months. The relationship was tumultuous although apparently settled at the time of sentence.
29 AB's mother reported the emergence of temper tantrums in AB at the age of ten. In early adolescence he began to emulate his father's violence. When his mother attempted to discipline him for this, his father would assault her. Sometimes he paid AB as much as $50 for his inappropriate behaviour. When AB was twelve his father encouraged him to break into a shop and, as a reward, he was given a motorbike.
30 AB commenced using cannabis from the age of seven or eight. This was known to his father and he drew upon his father's stored marijuana. By the age of twelve he was intoxicated on most days having started to drink alcohol when he was ten. By the time he was sixteen he described his use of alcohol as "really heavy." He started to suffer blackouts frequently. At the age of eleven AB frequently used hallucinatory mushrooms, ceasing this practice when he was seventeen. From the age of fourteen AB started to experiment with amphetamines and reported using them monthly until he was seventeen. His father supplied him on at least one occasion. He occasionally used LSD when he was fifteen and sixteen years old.
31 AB had been employed as a fence post cutter from the age of twelve. He also worked for his grandparents from time to time and has undertaken other short term and seasonal employment.
32 AB left school in the first term of Year 8 when he was fourteen, having truanted for some of his primary school and most of his high school years. His parents seemed to be unconcerned about this. He had been suspended from attendance on a number of occasions for violence and smoking cannabis. When he left school he was semi-literate.
33 Psychological testing of AB demonstrated a cognitive impairment to a greater or lesser extent against almost every measure and suggestive of some frontal lobe damage, probably related to chronic intoxication to some degree since early childhood.
