Teen's DNA found on rape, murder victim Joan Ryther's clothes The DNA of a man accused of raping and murdering pregnant woman Joan Ryther in Logan was found on the victim's clothes. THE DNA of a teenager accused of raping and murdering Queensland mother-to-be Joan Ryther was found on her clothes, a Brisbane court has heard. The 18-year-old, who can't be named for legal reasons, was denied bail during a hearing in the Supreme Court in Brisbane on Wednesday. Crown prosecutor Vicki Loury told the court the teenager's DNA was found on Ms Ryther's shirt and trousers. A bandage the accused was wearing also had blood stains that matched Ms Ryther's blood, she said. Ms Ryther was three months pregnant when she was attacked while walking to work at Logan, south of Brisbane, on the night of May 21. Ms Loury told the court there was evidence that placed the teenager in the street where the attack occurred. Justice Peter Applegarth said the crown had a "reasonably strong" case and denied bail. Earlier Tim Meehan, acting for the accused, told the court his client was of a "tender age." He argued bail was justified given the case would take some time to come to trial, and that could be as late as 2015. Mr Meehan said his client had co-operated with police and was not a flight risk. He argued the crown's case was not strong, but Justice Applegarth disagreed.
