A son accused of killing his elderly Melbourne mother will remain in police custody as detectives analyse "significant amounts" of DNA evidence.
Thomas Bednar, 53, was on Monday arrested and charged with the murder of his 78-year-old mother Judy Bednar after she was found dead in her Chelsea home on Saturday morning.
He did not appear during a brief filing hearing in the Melbourne Magistrates Court court on Monday evening.
His lawyer told Magistrate Victoria Campbell he was not aware Bednar had a history of psychiatric illness and was not withdrawing from drugs.
Bednar, however, does have a nightly prescription for 20 milligrams of temazepam, a medication used to treat sleep problems including insomnia.
It is his first time in custody.
Prosecutors have been granted additional time to gather CCTV footage, and send off "significant amounts of DNA evidence" and devices for analysis.
Bednar did not apply for bail and was remanded to next appear before court on October 4.
