THE man accused of beating toddler BJ Williams to death never disciplined him, a court has heard. Brock Michael Powell, 24, is on trial for the murder of BJ at Melrose Park in January last year. Prosecutors allege BJ sustained brain injuries and had extensive bruising around his face, torso and genital area. They allege Powell beat BJ and Powell repeatedly lied about it. Today BJ's mother, Latara Hunt, told the Supreme Court her former partner knew his boundaries when it came to her two children and Powell never disciplined BJ. Brock Michael Powell, 24, on trial for the murder of BJ Williams at Melrose Park in January last year. We never discussed it. He knew where he was when it came to my kids," she said. Ms Hunt told the court Powell had never hit her but he had thrown "a couple of things at me once that barely missed." Brock threw a cigarette container at my head that barely missed and put a hole in the wall behind me. Ms Hunt said, on the night of BJ's death, she and Powell had consumed methylamphetamine before going out for drinks with a friend. She said they argued when they returned and she went to sleep in her mother's house instead of in the granny flat they shared. She said Powell woke her up "in a panic, shaking me saying 'There's something wrong with BJ.'" Ms Hunt said when she ran to the granny flat, her son was on the corner of the bed and unresponsive. "Brock tried to give him mouth-to-mouth and I remember walking up and touching him and saying 'BJ' and he didn't respond at that stage," she said. The couple took BJ to Flinders Medical Centre. "There nurse tried to ask me what had happened and I sort of stuttered my words and I didn't know," she said. That's when Brock butted in and spat out what he said and I just agreed and the nurse was 'we are not talking to you, we are talking to her' and my reply was 'I don't know'. He said that he had woken up to a whinge and a thud and he thought it was BJ walking around to get into bed with us or get in bed with him. When BJ didn't appear around the corner he said he pulled the screen back and BJ wasn't laying in bed and that's when he found him on the ground between the wardrobe and the bed base. Ms Hunt said when she asked Powell about how BJ had sustained his injuries, Powell always had the same response. 'I found him on the ground.' Never changed, it never varied... whatever he told us stayed the same word for word every time we asked him.
