The 62-year-old tavern owner from Gqeberha, charged with the double murder of a Windvogel father and his son, made a brief appearance in the city's Magistrates Court on Tuesday.
Norma Jacobs has been charged with the murders and kidnapping of 45-year-old Edwin de Vos and his 19-year-old son, Leonardo.
Their bodies were discovered next to a gravel road near Addo in August last year.
Both had sustained gunshot wounds.
State prosecutor Melani Hammett told the court that the Investigating Officer had consulted with an Advocate, who in turn wants to consult with the state witnesses.
She asked that the case be postponed for further investigation.
In February, the State dropped all charges against Jacobs' co-accused, Thebisihle Selani.
It has not been placed on record whether Selani will be used as a Section 204 witness (State witness).
Jacobs, who had previously abandoned bail, for fear of her safety, has since been released on bail.
The father and son were both mechanics.
It is alleged that they had done repair work to the accused vehicle before their deaths.
The man and his son were last seen alive when they left their home in Windvogel with Jacobs, allegedly to go and inspect her vehicle.
Jacobs will appear in court again on 29 July.
