8 After the offender retreated into the home he stood for a time behind the screen door. From this position he called on the deceased to go home. The deceased called out repeatedly that he was going to kill the offender. One neighbour heard a male voice, that I am satisfied was that of the deceased, calling out "I'll kill you. I'll fucking kill you. If I don't kill you today, I'll kill you tomorrow." The voice sounded very angry. There were further threats called out by the deceased in this vein.
9 Yvonne Mace, who lived at 3 Corelli Close, observed a good deal of the events of that evening. She heard Julia Cadogan calling out to the deceased, "Alby can you just go home please". Later as the two men were struggling at the front she heard Julia say, "Leave him alone, go home, I've called the police". A little later she heard Julia telling the deceased to go home and saying, "He's had enough". She heard the offender call out, "I'm old, you belted me around the front yard, just go home and see you tomorrow, you're pissed Alby". The deceased replied, "Yeah that's right you are an old fucking cunt, I'm going to kill you, you bastard". The deceased was very angry he was punching the panels of one of the vehicles that was parked in the front yard.
10 Before Jason returned to the premises the deceased approached the front door. He told Julia Cadogan that his fight was not with her. He took hold of her and moved her away from the front door and he went inside the premises.
11 Within a very short time after entering the home the deceased had been stabbed by the offender. The wound was to the central upper back. The knife penetrated 9.5 centimetres into the deceased's body passing through a number of structures and penetrating the right lower lobe of the lung. The angle of entry was 30 degrees downwards. Considerable force was necessary to cause this injury.
12 Immediately after he inflicted the fatal wound the offender ran out of the house with the knife in his hand. He threw it into the rear yard. The deceased was still conscious and able to move for a short period following the stabbing. During this time the offender returned to the house, he apologised and endeavoured to render assistance to the deceased. When the police attended at the scene the offender was attempting to staunch the flow of blood from the wound. He told the police where the knife was to be found.
13 The central issue at the trial was self-defence. The provisions of Pt 11 Div 3 of the Crimes Act 1900 (NSW) applied in this respect.
14 The jury were directed as to the alternative verdict of manslaughter on two bases: excessive self defence within the meaning of s 421 of the Crimes Act 1900 or the inability of the Crown to prove that the offender was possessed of the intent that would make his act murder.
