A teenager has been refused bail after being charged with the murder of his flatmate who had been missing from their shared home in Sydney's south-west since last week.
Shuo Dong, 19, was taken to Campsie police station upon his release from hospital and was on Wednesday charged with the murder of 28-year-old Qi Yu.
Police said Ms Yu last made contact with her family in China on Friday night.
Police found her car in Burwood the following night, but she has not been heard from since.
Ms Yu's body has not been found.
At a brief mention in Burwood Court this afternoon police said they planned to analyse a forensic sample taken from the 19-year-old.
The application will be mentioned in court next month.
Shuo Dong did not appear in court, choosing instead to stay in his cell.
Bail was not applied for and it was formally refused.
A crime scene has been established at their unit in Campsie.
