A Dublin woman appeared before magistrates in South Africa today and heard it could take up to three months to formally extradite her back to Dublin.
Ruth Lawrence, 42, was detained last month in Bloemfontein on foot of an international arrest warrant.
She was arrested in South Africa as part of a garda investigation into a double murder in Co Meath over eight years ago.
On 12 October, a bail hearing heard that she was willing to be extradited.
Eoin O'Connor and Anthony Keegan were murdered in April 2014.
The friends were found wrapped in plastic sheeting and buried in a shallow grave on Inchicup Island, Lough Sheelin, in Co Meath.
It is believed they had travelled from Dublin to Co Cavan for a prearranged meeting. They were last seen on 22 April 2014.
The pair did not return to Dublin, prompting family members to raise the alarm.
It is believed Ms Lawrence travelled from Ireland to South Africa in 2014 with her then boyfriend Neville van der Westhuizen, who has also been sought for questioning in connection with the double murder.
Today, Ms Lawrence sat in the dock for the five-minute hearing before her case was adjourned and she was remanded in custody to a prison in Bloemfontein.
The National Prosecuting Authority said it estimated that the paperwork would be completed within three months to allow gardaí to fly Ms Lawrence back to Dublin for trial.
