18 Later that night the applicant and Wilson left to go to Mrs Thomas's house in Ferntree Gully, armed with a knife, a syringe and a mattock, which Wilson dismantled, separating the handle and the head. As they left in the applicant's car, Rebecca Thomas said to the applicant, "just make sure Mum's safe, make sure."
19 At about 2 a.m. the next morning Mrs Thomas was woken by dogs barking. Although her bedroom door was closed, Mrs Thomas heard the voices of Wilson and the deceased. Mrs Thomas telephoned her daughter and asked why Wilson was at the house. Rebecca Thomas told her mother that he was there to save and protect her. Mrs Thomas heard Wilson say loudly, "you raped my fucking sister, you cunt" and heard the deceased say something like "please, stop." Mrs Thomas picked up the telephone and Rebecca told her to go to the applicant, that he was there to get her. Mrs Thomas opened the bedroom door. She saw the applicant coming towards her with a stick in his hand. The applicant told her to get to the car. Mrs Thomas walked to the front door. Wilson was there. Mrs Thomas thought she could see the deceased's legs on the lounge room floor near one of the couches. Wilson told the applicant that the applicant had broken his arm and the applicant replied, saying he was sorry, he didn't mean to do it.
20 The applicant, Mrs Thomas and Wilson drove back to the applicant's house in Scoresby. Rebecca Thomas helped Wilson out of the car and into the house. He complained of pain in his arm. Rebecca Thomas said that one of the men had blood on his hands, face, watch and shoes. Wilson told her that he had stabbed the deceased in the head and the applicant had stabbed the deceased in the stomach. She recalled someone said that the deceased was dead.
21 According to Mrs Thomas there was a discussion as to what they were to say if the police became involved. It was agreed that Mrs Thomas would tell the police that she spent the night in Scoresby watching television and she had slept on the couch. The others were to say that they had remained at the house in Scoresby watching television. Rebecca Thomas said that the mattock handle, which had been taken to Ferntree Gully, was underneath the car upon its return to Scoresby. She picked up the mattock handle and, assisted by Wilson, hid it under the house. It was proposed that Mrs Thomas would take a taxi to the house in Ferntree Gully to collect her shoes for work that day and that she would find the body of the deceased.
22 Mrs Thomas went by taxi to the house in Ferntree Gully. She told the taxi driver that she had gone to her daughter's house, had watched videos and had decided to stay the night. She said she wanted to go home to collect her shoes and then to go to the city. At the house in Ferntree Gully Mrs Thomas left the taxi and entered the house. She then ran back to the taxi looking distraught. She told the taxi driver to ring the police and said that she thought "he was dead". The taxi driver entered the house and found the deceased, who was obviously dead.
23 Later the applicant was interviewed by the police. The version of events he gave to the police was as follows. He said that he was at home with Rebecca Thomas from 6 p.m. on 24 June 2005. He watched television. At 10.30 p.m. they received a telephone call from Mrs Thomas who said that the deceased had gone ballistic and given her a hiding. The applicant drove alone to Mrs Thomas's house and found her waiting outside. He drove her straight back to the house in Scoresby. He said that he was upset that Mrs Thomas had been hurt, for she seemed to be in pain, and to cool off he left the house and went to a hotel on the Maroondah Highway. He met "an Asian mate from Queensland" who was upset about an injury to his back. He took his friend to the Maroondah Hospital at about 3 a.m. Afterwards he took his friend to a motel and returned home at 5.45 a.m. He drove to his employer's place of business and returned to the house at about 10.30 a.m. Police found the blood-stained mattock handle under the house.
24 The applicant was arrested and re-interviewed. He said that after the telephone call from Mrs Thomas, the applicant and Wilson went to her house for the purpose of rescuing her. They knocked on the glass panel next to the front door and spoke to the deceased. The applicant said that he told the deceased that if he continued to behave as he had, they would call the police and have the deceased charged. The door opened and the deceased tried to punch the applicant. The applicant then punched the deceased and they scuffled. They fell to the floor of the sitting room, where the applicant repeatedly struck the deceased in the head. The deceased picked up the mattock handle and tried to swing it at the applicant. The applicant took the mattock handle from the deceased and struck him several times. He said: "I hit him as hard as I could...." The deceased lay unconscious and bleeding. When the applicant left the house the deceased was unconscious but still breathing. The applicant went to Mrs Thomas's bedroom and took her out from the house. The applicant said that he physically tried to restrain the deceased, but he was too strong. The applicant was frightened that if the deceased got up he would "just obliterate me because he is a good 20 or 30 kilos heavier than me and apparently he is very good with his hands."
25 A forensic biologist gave evidence of blood spatters found in the sitting room at the house in Ferntree Gully, which were consistent with the deceased being struck multiple blows with an elongated instrument. A pathologist who conducted an autopsy on the deceased said that his injuries included numerous stab wounds to the scalp, facial wounds, bruising to the neck and fracture of the larynx, numerous facial fractures, defensive wounds to his arms and hands, pattern bruises to his arms, bruising to the legs, a fractured skull and a heavy blunt impact injury to the left lower jaw. He attributed the death to multiple injuries, the fractured skull and associated brain damage, the facial fractures and compression of the neck. Traces of alcohol and methylamphetamine were found in the deceased's blood. As to the injury to the deceased's neck, the applicant said in his evidence that Wilson told him he had stepped on the deceased's neck.
26 The applicant gave evidence at the trial. He said that Rebecca Thomas told him that she had been raped by the deceased when she was between the ages of eight and ten years and that the deceased had assaulted Mrs Thomas. He was told about the deceased's paranoia and violent behaviour, which appeared to be escalating. The applicant said he had been told that the deceased was very strong and a capable fighter. He said he believed that the deceased was insane and that he was an extreme drug user.
27 The applicant said that on the night of 24 June 2002 Rebecca Thomas answered a telephone call from her mother and said to the applicant that she thought that her mother had been bashed. The applicant said that he concluded that if they did not get Mrs Thomas out of the house, she would be killed. Wilson and the applicant decided to go her house in Ferntree Gully to rescue Mrs Thomas. They armed themselves with a mattock handle, which the applicant took into the house to protect himself. When they arrived at the house the deceased spoke to Wilson through a screen door. When Wilson said that he wanted to come in and see his mother, the deceased told him to "fuck off". The deceased threw a punch at Wilson, and Wilson walked into the house.
28 The applicant said he waited outside hoping that Wilson would sort things out. He heard loud voices and a crash. He went into the house to help Wilson. In the sitting room he saw the deceased on top of Wilson on the couch punching him to the head and chest. The applicant ran up and punched the deceased twice in the head to get the deceased off Wilson. The punches had no effect. The applicant panicked and hit the deceased with the mattock handle. His intention was just to get the deceased off Wilson. He hit the deceased as hard as he could. He denied that he intended to kill the deceased or inflict serious injury. He could not recall how many times he struck the deceased on the head with the mattock handle. He stopped hitting the deceased when the deceased collapsed. The deceased had blood on his face but was still breathing. He appeared to be unconscious.
29 When asked why he hit the deceased so hard, the applicant said:
