A woman, extradited from South Africa yesterday, has been charged with the murders of two Dublin men nine years ago.
The woman who is aged in her 40's was detained after flying into Dublin airport, and brought before a special sitting of Trim District Court in Meath last night.
She was charged with the murders of Eoin O'Connor and Anthony Keegan on dates unknown between April and May of 2014.
The men who were both from Coolock in north Dublin, were found dead on a small island in Lough Sheelin in Meath, two weeks after they were reported missing.
