JUDGMENT
1 The offender, Shayne William Hansell, pleaded guilty to Manslaughter on 6 July 2007 in full discharge of an indictment charging Murder. The Crown accepted the plea on the basis that the offender's conduct caused the death of the victim, Troy Douglas Carney, on 29 January 2005, that the offender believed that his conduct was necessary in defence of himself or of others, but that it was not a reasonable response in the circumstances, in that the offender used excessive force. The offence of Manslaughter carries a maximum penalty of 25 years imprisonment.
2 The offender stands to be sentenced on the basis of an agreed statement of facts. No other material relating to the objective circumstances of the offence was provided. That statement of facts establishes that on 26 January 2005, the victim and his girlfriend, Ms Picker, went to the offender's home to see the offender's younger brother, Kenneth Hansell. The victim was moderately affected by alcohol at the time of his arrival at about 8:15pm.
3 Kenneth Hansell and the victim consumed a number of full-strength beers over the following hour, at which time the offender arrived with his wife and their seven year old daughter. The offender consumed two glasses of wine with his brother and the victim, both of whom were on good terms and were engaging in vigorous "horseplay". The evening continued in this fashion until about 11pm.
4 Shortly after 11pm, the offender's wife and their daughter left the premises to buy cigarettes at a local service station. The offender, his brother and the victim went outside, then returned to the lounge-room. By this time, the offender's brother was telling the victim to go home and the play fighting had escalated to the point where the offender's brother challenged the victim to hit him. The victim responded by removing a bracelet he was wearing and passing it to his girlfriend, who suggested they leave. Ms Picker left the house and went to her car, expecting the victim to follow.
5 The offender's wife and their child returned to the house. Ms Picker again urged the victim to leave and this time, the victim did leave the house, together with the offender's brother. Both these men were heavily intoxicated at this stage. Whilst Ms Picker was seated in the car, the victim punched the offender's brother, knocking him unconscious onto the ground. The victim then returned to the house, his shirt wrapped around his head, and stood looking into the premises while the offender made a 000 call at about 11:20pm. The offender's wife told the victim to go, however the victim responded by pushing her and headbutting her twice in the nose. Hearing her cries for help, the offender went to her aid, exchanging punches with the victim and wrestling him to the floor.
6 Ms Picker heard screams and returned to the house, where she saw the offender holding the victim face down on the lounge, with the offender's right arm wrapped around the victim's neck and the offender's body lying the full length along the victim's back. Pressure was being applied by the offender's forearm to the victim's throat. Any movement by the victim was met with further pressure to the throat. The victim lost consciousness and began to make noises consistent with restrictions to his airway. Ms Picker warned the offender that his actions were capable of killing the victim but the offender maintained his grip. Ms Picker felt for the victim's pulse and asked the offender to put the victim in the car, but the offender said he was not taking any risks and would wait until help arrived.
7 Ms Picker went outside for about five to ten minutes and when she returned, the offender's position and his grip upon the victim had not changed. Ms Picker noticed that the victim's fingers were going purple. Both the offender's wife and Ms Picker could not find a pulse at that stage. The offender's wife told the offender to place the victim on the floor and he complied. Shortly thereafter, the offender and his wife began performing CPR in an attempt to revive the victim. A call was made for an ambulance at about 11:55pm. When the ambulance arrived, CPR was continued until a pulse was retrieved, but the lengthy deprivation of oxygen resulted in significant brain injury, ultimately leading to the victim's death three days later.
8 The post mortem examination revealed severe neck compression. A complete cessation of air for no more than three minutes was sufficient to cause irreversible damage to the brain. It is apparent that the offender maintained and, on occasions, increased his hold on the victim's throat for a significantly longer period than three minutes, despite Ms Picker's warning and despite objective signs, namely the noises emanating from the victim's throat, that the victim had lost consciousness.
9 It is difficult to be precise, but it is unlikely that more than five minutes elapsed between the 000 call and Ms Picker's return to the house to see the victim being held by the offender. Ms Picker was alerted by the screams of the offender's wife, which co-incided with the victim's assault upon her, almost contemporaneously with the 000 call. There is no reliable evidence before me as to the length of time during which the offender and his wife were performing CPR prior to calling the ambulance. The offender's evidence was that he was not choking the victim for 10 whole minutes, but he conceded that he was on top of the victim on the lounge, applying varying degrees of pressure to the victim's throat for 10 minutes. In any event, the offender was hardly in a position to accurately gauge the passage of time.
