THE case against a teenager accused of the rape and murder of Logan woman Joan Ryther has been delayed due to DNA hold-ups.
Ms Ryther, who was three months pregnant when she was killed, was found in the front yard of a home in Woodridge.
She was attacked on her way to work at McDonald's in May.
Police prosecutor Sergeant Karen Friedrichs said the investigation had been significant and some forensic evidence was still being analysed.
''There is significant DNA evidence and analysis of clothes and various exhibits,'' she told the Beenleigh Magistrates Court on Monday.
Sgt Friedrichs said the bulk of evidence had been given to the defence, including 231 statements and 133 exhibits.
The 18-year-old accused has been in custody since his arrest in June, and will have to wait until next year to find out if he will stand trial.
The case has been adjourned until February 3.
