A woman accused of murdering her ex-wife remains in custody over concern that granting her bail to her previous address in Adelaide’s south would place her near 35 witnesses in the case, a court has heard.

Prosecutors opposed bail for Anastasia Marshall, 29, pending a Supreme Court Review of her bail application on Monday. 

Ms Marshall — and a man whose name is suppressed — are charged with murder over the death of Krystal Marshall last year. 

The 38-year-old mother was found dead at the scene of a house fire on Barracoota Crescent at Aldinga Beach on October 20.

Anastasia Marshall has previously denied the charges.

Last week, a magistrate granted home detention bail after determining there were “no substantial” safety concerns for the public and no risk of Ms Marshall absconding.

The prosecutor asked for that decision to be reviewed by the Supreme Court.

In the review on Monday, Justice Tim Stanley raised concern about granting Ms Marshall bail to her previous address due to 35 witnesses in her case living in the same area.

The Crown previously argued the gravity of the alleged offending and the likelihood of interference with potential witnesses meant that Ms Marshall was not a good candidate for bail.

The prosecutor told the court there were “numerous prosecution witnesses … who still reside either in that direct area or nearby”. 

Justice Stanley said he also had a “suspicion” that many witnesses on the list provided by the Crown still lived in the area and was “not prepared to allow her [Anastasia] to be bailed to that address in Aldinga.”

He advised her defence that a new location would be needed before he upheld the Magistrate Court decision to grant her bail.

The bail application was adjourned to next week.
