A Melbourne man accused of the cold case murders of two siblings has significant health issues and is currently being treated with morphine, a court has heard.
Glen Nash, 58, fronted the Melbourne Magistrates' Court on Thursday where he was remanded in custody over the murders of Doris McCartney and her brother Ronald Swann, whose bodies were found in October 1989.
Mr Nash, who was charged earlier that morning, appeared by videolink wearing a grey long-sleeved top.
His barrister, Neville Rudston, told the court that it was his client's first time in custody.
"There's significant health issues … also, your honour, mental health issues," he said.
The court heard that Mr Nash, of Rowville, was also undergoing radiotherapy treatment.
He spoke sparingly, only acknowledging that he could hear the magistrate.
The bodies of Ms McCartney, a widow, and Mr Swann, who was a World War II veteran, were found at their home on Keith Street in Moorabbin more than 31 years ago.
The mystery over their deaths has long been a source of anguish for family members.
Last week, Victoria Police offered a $1 million reward for information about the case.
Mr Nash will return to court in July.
