Adam James Matthews pleads not guilty to murder of Scott Miller after a fight at Darlinghurst AN accused murderer who punched an acquaintance, causing him to hit his head on an iron railing, didn't know the man had an aneurysm in the base of his brain, a Sydney murder trial has heard. The death of Scott Miller after a fight at Darlinghurst in inner Sydney in February 2011, was "a rare event and something that was completely unforeseen," the Supreme Court was told on Tuesday. Adam James Matthews, 38, has pleaded not guilty to murdering Mr Miller, who died three days after the alleged attack on February 19. The court would hear evidence Matthews punched Mr Miller and stomped on his head while wearing thongs, crown prosecutor Trevor Bailey said in his opening submissions. Mr Miller had an aneurysm which made him susceptible to bleeding of the brain, but Mr Bailey told the jury, "It doesn't matter that the aneurysm was there." There will be evidence (Matthews) struck (Mr Miller), and at the time he intended to do him really serious harm. The court heard Matthews had been drinking at a hotel in Darlinghurst before he saw Mr Miller on the street and told a mutual friend, "I don't like him." He then approached Mr Miller on the street and a fight broke out, the jury was told. "The accused started the fight and initially he came off second best," Mr Bailey said. Mr Miller, who was a big man, knocked him to the ground. Matthews then went for Mr Miller and struck him in the jaw, the court heard. "Mr Miller fell and hit his head on an iron railing," Mr Bailey said. A number of witnesses say the accused, who was wearing thongs, then proceeded to stomp on the head of Mr Miller as he lay on the ground. Defence barrister Nathan Steel said Matthews denied stomping on Mr Miller's head and this would be supported by the evidence. "I anticipate a forensic pathologist will tell you had that been the case, he would have expected to see worse injuries than were observed," Mr Steel said. He said Matthews had no idea that Mr Miller suffered from an aneurysm when he got into a fight with him. "Adam Matthews didn't know that Scott Miller had this aneurysm at the base of his brain," Mr Steel said. It may well be the case that Scott Miller didn't know. During this fight, Adam Matthews didn't know that a punch to the jaw would have caused this aneurysm to burst. He didn't know this would have resulted in Scott Miller tragically dying. What happened was a rare event and something that was completely unforeseen. Mr Steel noted that Matthews was also punched in the face during the fight.= You wouldn't think when Scott Miller threw that punch he did so because he was intending to kill (Matthews) or cause him serious injury. Likewise, we say the same applies to the accused. When people punch someone to the jaw or face, they're not intending to kill that person or cause them serious physical injury from such a blow. The trial continues before Acting Justice Jane Mathews.
