The Supreme Court trial of Kylie Jane Hack and Gary Matthews for the alleged murder of Kingston woman Michelle Meades has been delayed.
Ms Meades' remains were found in a burnt out home in Clarendon Vale in September 2016.
The Crown said the delay was the result of many volumes of Crown papers, the review of forensic material and more material to come.
Justice Michael Brett said he was concerned about the delay because Ms Hack, who is innocent until proven guilty, has been held in custody since 2016.
"I'm concerned about the fact she is still in custody and we don't have direction as to when a trial will be," Justice Brett said.
Ms Hack is charged with murder, failing to report a killing and arson.
Mr Matthews is charged with assault, accessory after the fact of murder and failing to report a killing.
Justice Brett adjourned the matter and Ms Hack and Mr Matthews will reappear on March 20.
