Mosa Julius Mbele Guilty A man accused of killing a teenage boy because he wanted to show he "owned" a Sydney suburb has been found guilty of murder. Mosa Julius Mbele showed no reaction as the jury handed down its guilty verdict at the Supreme Court on Friday following a day and a half of deliberations. Mbele was charged with murdering the 16-year-old, who can't be named for legal reasons, at Bankstown train station in Sydney's southwest on May 25, 2011. He had pleaded not guilty on the grounds of self defence. In her closing submissions earlier this week, Crown Prosecutor Nanette Williams told the jury they should have no doubt Mbele was the aggressor as he had armed himself with a knife. "This (the stabbing) was a willed act, filled with planning, anger and wanting to let (the teenager) know who ran Bankstown," she said. The court had heard Mbele, then 22, and the dead youth traded a number of physical and verbal blows in and around the station in the hours prior to the stabbing. In one of the altercations Mbele allegedly told the 16-year-old, "I run Bankstown, I own Bankstown." " (The teenager) was a threat to the accused's claim and supremacy at Bankstown railway station," Ms Williams said. The 16-year-old boy's mother hugged the crown prosecutor just after the verdict was handed down. Outside court his extended family quietly hugged one another before thanking police officers for their ongoing support. Mbele will appear before Justice Megan Latham again in August for a sentence hearing.
